NADCA Educational Course: Learn the Technology and Processes for Inspecting Die Castings

Posted by Beau Glim on Jul 17, 2019 10:53:25 AM

Understand the advantages of die casting inspection processes

The advantage of the die casting process is to create highly complex geometry parts quickly. Couple this with the disadvantage of die casting, producing parts with internal porosity, and the job of ensuring quality becomes more challenging. This series will take a look at some of the technology and processes for inspecting die castings.

Part 1 - Internal Inspection - This session will look at how to detect porosity in a die casting. From simple density analysis through Computerized Tomography (CT) scanning, this series will look at how the process/technology works and the advantage and disadvantages of each.
Date: July 23, 2019

Part 2 - External Inspection - This session will look at measuring the geometric dimensions of a die casting. Coordinated Measuring Machines (CMMs) have been used extensively for measuring the dimensions and form of die castings, but technology is developing new ways.
Date: July 24, 2019

Part 3 - Functional Tests - This session will look at how functional tests are developed and implemented for die castings. Parts that require pressure or leak tightness need some way to measure that.
Date: July 25, 2019

NADCA Educational Course: "Find Out How Die Casting Lubricants and Sprays Affect Casting Quality

Posted by Paul Brancaleon on Jul 3, 2019 9:40:52 AM

This NADCA series will look at, die sprays, plunger lubricants and their effect on casting quality.

With an in-depth discussion of both die and plunger lubricants we will look at their chemistry, function, application and effects on casting production and quality. The course will review pulse spray, its application and results at two production facilities. Hydrostatic spray will also be reviewed with application examples and use of hydrostatic spray.


(Illustration from the Hill and Griffith Company archives.)


Part 1 - Fundamentals - This course will go through the fundamentals of die casting lubricants. The course starts with the basics of the conventional use of external lubrication and cooling of die cast dies. The methods of spray application and the reason lube is applied to die casting dies. The function, chemistry, care and maintenance of the lubricants is reviewed. The spray section ends with review of potential defects caused by variation in spray application. For each defect, solutions to resolve those defects are taught.

Die Casting Problems - Gas Porosity And Surface Defects

Posted by Hill and Griffith Company on Jun 27, 2019 1:59:47 PM

NADCA EC-515 Die Casting Defects Course Review, Basics for controlling die casting defects - By Dr. Steve Midson

Gas porosity is the biggest single problem in die casting. High gas content prevents heat treating or welding and makes strength unpredictable.

  • There are three major sources of gas porosity for die castings: Trapped air, Steam, Gas from lubricant
  • Gas porosity is round and generally smooth, although it can be flattened to some extent by pressure
  • The actions to reduce gas porosity, in general, are not the same as the actions for reducing shrink porosity

Science or Black Art?, Die Casting Lubricants

Posted by Hill and Griffith Company on May 29, 2019 7:20:21 PM

Article for North America Die Casting Association (NADCA) “Die Cast Engineer Magazine” 2007 by Tim Cowell, Technical Director for The Hill and Griffith Company

Introduction

Early on in the Die Cast Industry, die lubricants were usually a concoction of various compounds that the die caster had available to him.

1. He would create different mixtures and whatever yielded the best results for his specific application was what he used. Although much was learned from this trial and error type of evaluation, this method of die lubricant development was considered more of a “Black Art” than a science. Several decades later, there are some who still believe it. Over the years, die lubricant manufacturers and others have gone to great lengths to develop laboratory methods aimed at correlating a product’s performance in the lab with how it will perform in production, and yet there are still no standardized scientific methods within the industry for evaluating die lubricants. The only true test to determine the functionality of a new die lubricant is by its introduction to the production environment.

GRIFLUBE® Bio-Syn Biodegradable Hydraulic Fluid

Posted by Dr. Morris Murphy on May 15, 2019 2:44:21 PM

GRIFLUBE® Bio-Syn will readily biodegrade as defined by OECD 301 C; and will easily exceed the 60% minimum biodegradability standard, converting CH3-CH2 molecular groups to CO2 within a maximum of 7 days, which exceeds the biodegradability rate of any polyether or polyol ester type fluid.


Hill and Griffith is pleased to submit the following technical information on our Factory Mutual approved fire resistant GRIFLUBE® Bio-Syn hydraulic fluid, as the proactive chemistry of choice for high production foundries, steel mills, casting operations, refineries, and any application which might be predisposed to elevated temperature extremes and have the potential for fire. GRIFLUBE® Bio-Syn was researched and designed as a superior biodegradable fire resistant hydraulic fluid, in comparison to conventional polyol esters, PAG/polyethers, and especially phosphate esters; to offer greater latitude relative to toxicological and environmental compliance, enhanced fire resistance, and maximum lubrication value, for extended wear characteristics in vane and axial piston pumps.

NADCA - Thermal Control Webinar Series - Diecasting

Posted by Dr. Morris Murphy on May 8, 2019 9:29:10 AM

Controlling the temperature of a die casting die through the location of cooling lines is critical to performance and die life.


A properly designed system of water and/or oil lines will process heat energy so the die can be operated productively with the highest part quality possible. NADCA has created a three level approach to addressing thermal control. This series is broken down by beginner, intermediate and advanced courses suitable for people with varying levels of knowledge in this area.
