NADCA Congress Session Spotlight - Tim Cowell, Technical Director at The Hill and Griffith Company to present at the Die Casting Congress & Tabletop 

In the weeks leading up to the 2017 Die Casting Congress & Tabletop NADCA highlights information on papers that will be presented during the congress sessions. The following paper is scheduled to be presented on Wednesday, September 20: Computer Modeling II - 8:00-9:30 AM, Session Chair: Charles Monroe

Plunger Lubricants and Porosity: How they interrelate within the Die Casting Process
Timothy Cowell, Technical Director, Hill and Griffith Company

High Pressure Die Casting is a manufacturing process in which molten metal is injected, with a die casting machine using applied force and high pressure, into a steel die to form various products (castings). Within this process, there are large numbers of variables that need to be controlled to make an acceptable casting. If these variables are not controlled then defects within the castings (parts) occur making them unusable.

Hill and Griffith Company at the 2017 Metalcasting Congress Show

Posted by Hill and Griffith Company on Wed, May 03, 2017 @ 10:01 AM

It was a very successful 2017 Metalcasting Congress show according to the traffic at our booth and many of the attendees.

Joe Murphy, sales representative for MODERN CASTING Magazine said, "It was good seeing you at Metalcasting Congress. Having personally visited over 70 exhibitors, by nearly all accounts it was a terrific, upbeat, positive and very productive show for many. (As I shared with you, one supplier has now gone to a second shift and moved to a larger facility to keep up with the demand of "more back orders than they've ever had in the company's history." This is a direct verbatim quote.)

Cleveland Rocks with Grifcote FR 50 Concrete Form Release

Posted by Hill and Griffith Company on Fri, Feb 03, 2017 @ 10:57 AM

(This week's post comes from CONCRETE PRODUCER and their article titled "Cleveland Rocks, Allega Cos. answers Corps contract commanding nearly 120,000 tons of wave-worthy precast." Here's a link to the article. They included this statement about Hill and Griffith in a caption to one of the photos, "Lindsay Precast Concrete demonstrated handling and stripping features of a prototype prior to a nod from Anthony Allega for 49 additional dolos forms. After testing a handful of form oils, the producer opted for Hill & Griffith’s Grifcote FR 50 Concrete Form Release.")

Cleveland Rocks 

Hill & Griffith’s Grifcote FR-50.

 

A weather front emanating from Superstorm Sandy in October 2012 tested infrastructure well inland of metro New York and New Jersey, the area hardest hit by precipitation, wind and storm surge. Among federal and state agencies contending with long-term responses to Sandy-level exposure is the U.S. Army Corps of Engineers Buffalo District. It capped the 2015 and 2016 construction seasons closing repair and upgrade contracts—Oswego Harbor Detached Breakwater, New York; Cleveland Harbor East Breakwater, Ohio—using non-proprietary precast concrete structures known as dolosse, in tandem with limestone or granite armor block.

District engineers outlined finished structure air content, flexural and compressive strength, plus surface quality specifications for respective Oswego and Cleveland project precasters, Lakelands Concrete Products of Lima, N.Y., and Allega Cos. of Valley View, Ohio. Both determined that highly fluid, self-consolidating mixes are the best solution for accelerated production of structures that will be submerged or subject to frequent Great Lakes wave exposure through a service life plausibly extending into the next century. Early indicators suggest the dolosse installations contribute to a Corps roster proving the efficacy of SCC for structures prone to extreme weather or temperature events, sharp freeze-thaw cycles, and rare, but catastrophic loads.

Hill & Griffith’s Grifcote FR-50.

Dolosse resist breakwater or shoreline erosion from waves and undercurrent through their mass and energy-dissipating geometry. Known as dolos individually, the monolithically cast structures comprise three members of octagonal cross section: Uniformly sized shanks connect fluke ends. The latter are flared, tapered members running in opposite directions, along X and Y axes. Dolosse are fabricated in four- to 16-ton sizes, sans lifting hardware, and placed by sling so each structure interlocks such that even the most forceful waves or undercurrents meet long plain or reinforced precast concrete chains of inordinate tonnage.

The Corps Buffalo District used a formula factoring statistical 20-year wave height and 10-year water level to determine 16-ton and 6.5-ton dolos sizes for the New York and Ohio installations. Located near the southeastern corner of Lake Ontario and serving the first U.S. port from the St. Lawrence Seaway, the upgraded Oswego Harbor structure marks the District’s first use of 16-ton dolosse. Lakelands Concrete fabricated 997 of the 11-ft. long structures with conventional reinforcement (Concrete Products, July 2015). The dolosse represented the bulk of a $19 million contract Michigan’s Durocher Marine completed in November 2015.

Slightly trailing the New York engineering and casting schedule were preliminaries for the much more ambitious Cleveland Harbor work, centered in Lake Erie about two miles east and one-half mile north of downtown Cleveland. Buffalo District engineers specified the 6.5-ton dolosse, plain and 8.3-ft. long, for 4,400 feet of breakwater structure, which sustained more than $31 million in damage attributable to the Superstorm Sandy-spurred weather system. The Corps found that the intensity of the winds over Lake Erie created extraordinarily rare waves, measured at nearly 18 feet offshore of Cleveland.

Great Lakes Dock & Materials customized a precast handling device in house, and turned to a GPS-guided, crane cable-mounted topographical 3D system, Posibloc, for precise dolos placement. Companion Visibloc technology recorded each unit’s location, so the crane operator could target subsequent placements for optimal density and interlocking. Although not Posibloc-prescriptive, the Cleveland Harbor contract required a system a) with positioning technologies and sensors to produce a 3D image of dolos being placed; b) capable of guiding the crane operator to place units in designated positions with interlocking control; and, c) equally accurate above and under water.

The contractor deployed two 100-dolosse barges for June 2015–November 2016 breakwater repairs and upgrades. Anthony Allega Inc. began fabrication in April 2015, whereby Great Lakes Dock & Materials approached peak season with a two- to three-month dolosse inventory. SITE PHOTOS: Andrew Kornacki, Corps Buffalo District

CONTRACT ESCALATION

MasterGlenium HRWR assured self-consolidating properties in the mixes for the dolosse, each requiring 3.25 yd. Between its rapid placing rate and zero vibration requirements, the self-consolidating concrete proved critical to a 300- to 350-dolosse weekly production schedule. Allega Cos. mobilized fabrication at its headquarters property, running on both sides of the Interstate 480 crossing at Valley View, Ohio. PLANT PHOTOS: Concrete Products

After securing the precast contract, Allega Cos. mapped a dolosse production and storage plan at its headquarters, south of Cleveland and about 15 miles from a precast off-loading point. The site is the base of fleet and plant equipment supporting Anthony Allega Inc., a building and heavy/civil contractor operating mainly in Ohio; and Allega Concrete Corp., a four-plant, northeastern Ohio ready mixed producer.

Seasoned in precast barrier and sound wall fabrication, Anthony Allega enlisted Canal Fulton, Ohio-based Lindsay Concrete Products to fabricate 50 forms, enabling 300 dolosse output on a six-day schedule. Through lead Cleveland Harbor contractor Great Lakes Dock & Materials LLC, Muskegon, Mich., the Corps initially called for 12,577 dolosse. Anthony Allega was set to cover that quantity over an April 2015–October 2016 production window. Site assessments, coupled with the availability of additional funding, compelled Buffalo District engineers to increase the precast order to 18,257 dolosse. The schedule for two shifts of casting plus form stripping and maintenance crews went from six to seven days a week in 2016.

The option of self-consolidating mix specifications allowed Anthony Allega and Lindsay Precast to design freestanding dolos forms, with the 1.67-ft. octagonal end of a fluke serving as the lone charging port. Individual stands bear two hinged form sections: one main, with full 8.3-ft. fluke and shank tapering from 2.67 to 1.67 ft.; the other with remaining fluke and clamped end. Anthony Allega staged production between a 200-yd./hour batch plant and storage area equal to 2,000 dolosse.

Concrete Form Release Agent Biodegradability

Posted by Hill and Griffith Company on Thu, Nov 17, 2016 @ 05:02 PM

Biodegradability Redefined and Volatile Organic Compounds Update

Government regulations are changing the rules for compliance – but what are they?

January/February 2010 | PRECAST INC.

By Bob Waterloo , Technical Sales Manager, Concrete Release Agents, Hill & Griffith Co., Indianapolis

Have you ever played a game with others and in the middle of the game they start changing the rules? Frustrating, isn’t it? Or maybe you played a game and nobody knew what to expect next. You don’t know if the old rules apply, or if they are making the game up as they go along (perhaps so they can win?). On the other side of the coin, perhaps the changes were made so that the playing field is leveled, or perhaps the original “rules” were unreasonable and left everyone confused and in doubt.

    It appears that this is what is happening with the definition of biodegradability. New federal rules, regulations and definitions are now in effect, but there has been little in the way of notification to the players. The purpose of this paper is to provide precasters with current information on this changing environmental landscape to help them make decisions regarding form release agents.

Biodegradability

One thing is for certain: Humans generate a lot of garbage (both personal and industrial), some of which is considered toxic waste and some of which will contaminate our environment. Perhaps we won’t see the impact of this contamination for years to come. Other waste, both personal and industrial, will degrade back to the natural environment over a short period of time and may even be beneficial to our environment. But how do we know what is – and what is not – environmentally acceptable? And what are we using in our plants that is environmentally responsible or detrimental to the environment?

    As outlined in “Form Release and the Law” (Precast Inc., Jan/Feb 2006), the word “biodegradable” has been terribly misused. Given enough time, everything is biodegradable. Unfortunately, in many cases, by the time the degrading process has taken place, the environment is contaminated. For that reason, and many others, I’m sure, the U.S. Environmental Protection Agency (EPA) issued guidelines as to how and when the word “biodegradable” can and should be used. Further, while there is no official organization to verify the use of the claim of biodegradability, the U.S. Federal Trade Commission (FTC) has issued some general guidelines on what type of products qualify as legitimately biodegradable. They have even sued some companies for unsubstantiated, misleading and/or deceptive use of the term on product labels.

    More attention is now being paid to biodegradability, and many agencies, companies and organizations are getting involved. Again, given enough time, anything is biodegradable.

    Because the word “biodegradable” has been inappropriately used in the past, it is important that we understand how it is truly defined and what criteria a product must meet in order to be considered biodegradable. One definition of “biodegradability” can be found in the EPA 1998, “Fate, Transport and Transportation Test Guidelines, Office of Prevention, Pesticides and Toxic Substances (OPPTS) 835.3100, Aerobic Aquatic Biodegradation”; and in EPA 712-C-98-O and ASTM D-5864-00, “Standard Test Methods for Determining Aerobic Aquatic Biodegradation of Lubricants or Their Components.” This reference gives everyone the guidelines to be followed when determining biodegradability and using the word “biodegradable” in claims relating to various products, including concrete form release agents. The U.S. EPA definition includes an allowable “28-day half-life” of materials in order to be considered biodegradable. Half-life is the time required for the decay of one-half of a given component in a system.

    Precast operations that are near free-running water or have relatively shallow aquifers should be especially concerned about contaminants in the soil that may adversely affect the environment. A word of caution: Just because a release agent is “water-based” does not necessarily mean it will meet the EPA requirement to be classified as biodegradable. If you plan to use a form release (or any material, for that matter) that claims to be biodegradable, ask whether the material meets the 28-day half-life criteria that U.S. EPA describes. As there are often misunderstandings on the term “biodegradable,” it is wise to go that extra step in clarifying that the material meets the criteria you require.

    While it appears that there are no federal mandates on biodegradability of concrete form release agents, we can certainly expect new rules and regulations in the future. How soon is anyone’s guess, but we do see more precasters trying to pre-empt the regulations that are expected, or are in some cases already in effect in their local region (wetlands are a good example).

    Based on my research, there is no current legal definition of “biodegradable” or “biodegradability.” The ASTM (American Society for Testing and Materials) defines the term as “degradation caused by biological activity, especially enzymatic action, leading to a significant change in the chemical structure of the material.” The EPA, however, has given more specific guidelines of biodegradability (like the 28-day half-life that have been accepted by industry and governmental agencies.)

    Based on the Federal Trade Commission (FTC) definition, only products that contain materials that “break down and decompose into elements found in nature within a reasonably short amount of time when they are exposed to air, moisture and bacteria or other organisms” should be marketed as “biodegradable.” Also, the FTC acknowledges that even products appropriately labeled as biodegradable may not break down easily if they are buried in a landfill or are otherwise not exposed to sunlight, air and moisture, the key agents of biodegradation (aerobic vs. anaerobic).

    According to federal regulations (Federal Register Part 260 16 CFR 260 7), the claim of biodegradability must be substantiated using environmental biodegradable testing. As form release agents are subject to both aerobic (with oxygen) and anaerobic (without oxygen) conditions, it is normally necessary to evaluate degradation under both conditions before claiming “biodegradability” to whatever extent.

    The half-life of a material is still the most common definition of whether a material can truly be considered biodegradable. That is still true, but there have been alternative guidelines published that change the wording and allowances of being biodegradable. Originally, concrete form release agents were required to have a half-life of a maximum of 28 days in order to be classified as biodegradable. (EPA 1998 Fate, transport and transportation test guidelines, office of Prevention, Pesticides and Toxic Substances (OPPTS) 835.3100, “Aerobic Aquatic Biodegradation”; and in EPA 712-C-98-O and ASTM D-5864-00, “Standard Test Methods for Determining Aerobic Aquatic Biodegradation of Lubricants or Their Components”)

    The Consumers Union maintains that if a manufacturer has solid scientific evidence demonstrating that the product will break down and decompose into by-products found in nature in a short period of time, then claiming that it is “biodegradable” is not deceptive. Words like “Environmentally Acceptable,” “Environmentally Friendly,” “Environmentally Preferable” and “Environmentally Responsible” are also used to describe items produced with biodegradable materials or, in many cases, part biodegradable material, without knowing if the whole formulation could be rated as biodegradable.

    The California Advertising Statute, amended April 30, 1991, states that a manufacturer cannot claim that a product is biodegradable unless it meets the following definition: “Biodegradable means that a material has the proven capability to decompose in the most common environment where the material is disposed of within three years through natural biological processes into nontoxic carbonaceous soil, water, carbon dioxide or methane.”

    Also, the term “bio-based” is used to describe products from vegetable, plant or animal based materials. However, just because the term “bio-based” is used, it does not necessarily mean the composition is readily biodegradable or ultimately biodegradable. It would depend on the other base oils that may be included in the formulation.

    The EPA and FTC (Federal Trade Commission) have restated the definition of biodegradability into two specific clauses:

1. Readily Biodegradable – Pertaining to the material having a 60 percent or greater degradation in 28 days.

2. Inherently Biodegradable – Pertaining to having a maximum half-life of 60 days or less.

The Degradation Accumulation Expert Group of the Organization Economic Cooperation Development (OECD) Environmental Committees has established a series of tests that classify compounds as:

• Readily Biodegradable – Rapid and compete mineralization

• Inherently biodegradable – 20 percent to 70 percent biodegradable within 28 days

• Non-biodegradable – Negligible removal of material under test conditions

The OECD recommends that degradation rates, or half-lives, are preferably determined in simulation biodegradation tests conducted under conditions that are realistic for the particular environment they are subject to or presented with (surface water, sediment, soil, etc.).

    The OECD’s 301-B CO2 Evaluation Test (Modified Sturm) is probably the most recognized test in the lubricant (petroleum solvent) industry, and is listed in the EPA Guidelines.

    The EPA and FTC now recognize ASTM OECD-301 B Modified Sturm procedures within ASTM-5684-00 and CEC- 33-T-82 as “Standard Test Methods for Determining Aerobic Aquatic Biodegradation of Lubricants.” While these tests may be expensive, they provide reliable and repeatable results for testing of biodegradability. The test method “covers the determination of the degree of aerobic aquatic biodegradation of fully formulated lubricants or their components on exposure to bacterial inoculums under laboratory conditions,” according to the “Renewable Lubricants Manual” (see listing in “References”).

 

Concrete Form Release agent VOC limits resized 600

Volatile Organic Compounds in the United States and Canada
    United States. In September 1999, the Environmental Protection Agency enacted Volatile Organic Compounds (VOC) regulations that affect the concrete industry. These regulations can be found in the Federal Register, Vol. 63, No. 176, Friday, Sept. 11, 1998, under 40 CFR-59, [AD-FRL-6149-7], RIN 2060- AE55, National Volatile Organic Compound Emission Standards for Architectural Coatings, pages 44848-48887. There are 64 materials used in the concrete industry that are subject to VOC regulations and limits. Concrete form release agents are listed (specifically) and allowed a maximum of 450 gallons per liter (g/L). Further, some individual states have passed legislation allowing a maximum of 250 g/L or 2.1 pounds per gallon of VOCs. Fifteen states and the District of Columbia have passed legislation reducing the allowable levels of VOCs in concrete form release agents from 450 g/L (federal allowable levels) to 250 g/L. Keep in mind that any state can have more stringent requirements than the federal levels, but no state can be less stringent than federal levels. As of today, the following states have maximum allowable levels of VOCs of 250 g/L: California, Illinois, Ohio, Virginia, Connecticut, Delaware, Maine, Vermont, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and the District of Columbia. All of these states are members of the South Coast Air Quality Management District (SCAQMD), the Ozone Transport Commission (OTC) or the Lake Michigan Air Directors Consortium (LADCO). While individual states have taken the initiative to make changes in lower allowable VOC levels, the
EPA has yet to act on making the requirements nationwide. We can, however, expect the bureaucracy to follow suit in the near future based on the number of states that have already taken this step forward.
    The U.S. EPA has been forecasting changes to the VOCs (on form release agents and other products), but has not taken any steps to make these changes. It continues to forecast “in six months,” but has not yet taken any definitive action. Is EPA leaving the individual states to make the changes in anticipation of a federal mandate? Perhaps so, considering the activity of state legislatures to take matters into their own hands without federal government involvement.

Canada. The Canadian Ministry of the Environment – Environment Canada has also become a player on VOCs. Dating back to April 26, 2008, the Ministers of Environment and Health published a Notice of Intent entitled “Federal Agenda on the Reduction of Emissions of Volatile Organic Compounds from Consumer and Commercial Products.” This document outlined a series of measures intended to reduce emissions. The thenproposed “Volatile Organic Compound (VOC) concentration Limits for Architectural Coating Regulations” were published in the Canada Gazette, Part I, on April 26, 2008. The proposed regulations set out specific VOC concentration limits for 49 categories of architectural coatings, including form release compounds. In the case of concrete form release agents, the effective date for a maximum allowable level of VOCs of 250 g/L is Sept. 9, 2012.

Conclusions
• Biodegradable/biodegradability continues to be left to ambiguous interpretation. However, there are now established test methods that give positive indications of the environmentally friendly or responsible attributes of many materials, including form release agents. It behooves you and your supplier to discuss and substantiate claims of biodegradability in order to protect your operation and your environment.
• Biodegradability “redefined” has some benefits to the precast industry as there are some petroleum solvents that are readily and inherently biodegradable. On the negative side, there is a price to be paid for this quality.
• We can expect the U.S. EPA to continue its efforts in reducing VOCs to a federal level of 250 g/L.
• Without specific testing, it is difficult for a supplier to the industry to make claims regarding biodegradability and VOC compliance. As definitions become more specific, and allowable testing procedures are outlined, suppliers must invest in the precast industry by making reliable data available to the precaster.

Sixth graders at Oakridge Upper Elementary School, Muskegon Mich., dug their hands in sand to build molds to make castings last week as part of an AFS Foundry in a Box demonstration. Reg Crowe, retired, Jill Koebbe, Air & Water Compliance Group, Jeff Cook, Eagle Alloy Inc., and Rob Kriger, Eagle Alloy Inc., led students in Mrs. Rikki Grave’s 6th grade science class on Friday, March 13, showing them how to make a sand mold, pour molten tin, remove the sand from the solidified casting and clean the casting’s surface. Since its inception, the Foundry in a Box has been utilized at events and schools throughout the country. For more information on Foundry in a Box, click here.

The American Foundry Society is a not-for-profit organization formed in 1896. With its headquarters in Schaumburg, Ill., AFS provides members and consumers with information and services to promote and strengthen the metalcasting industry.
