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.

Learn to Properly Operate the Die Casting Machine

Posted by Hill and Griffith Company on May 24, 2017 4:28:39 PM

Setup, Startup, Warm-up, Shutdown and Safety - Learn to Properly Operate the Die Casting Machine with courses from the North American Die Casting Association.

This year NADCA will be focusing on presenting thier Nation Courses in webinar format. This will allow participants to gain a thorough understanding of the subject matter without the additional cost of travel. There is also the option to attend all courses in a designated Level in order to fulfill certification requirements. NADCA's Operating the Die Casting Machine series is next up on their 2017 course list. Operating the Die Casting Machine is a course detailing the basic die casting setup, startup, warm-up and shutdown.

The Role of Die Casting Lubricants Video

Posted by Hill and Griffith Company on May 17, 2017 2:35:37 PM

The material presented in this video are some highlights from NADCA’s online webinar – The Role of Die Casting Lubricants  – presented by NADCA’s Beau Glim. Die lubricants are a necessary part of high pressure die casting. The lubricant provides a thin layer to protect the die steel from molten metal. The full presentation discusses what die lubricants are and characteristics important to die casting, how to apply die lubricants in operation, problems caused by improper use of die lubricants, and alternatives to conventional die lubricants.

Mold Releases and Release Agents Information

Posted by Hill and Griffith Company on May 10, 2017 4:02:47 PM

Film-forming lubricating oils, solid lubricants, waxes, or fluids that prevent other materials from sticking or adhering to an underlying surface are called mold releases and release agents. Unlike permanent non-stick coatings, release agents typically require replenishment and are non-curing.

Release Agents for Die Casting: General Aspects and State of the Art

Posted by Hill and Griffith Company on May 5, 2017 3:47:50 PM

Some basic features are common for all kind of release agents (R.A.). They are:

  • Incompatibilty with the product to be demoulded both chemical and physical. If moulded material absorbs the release agent, release power is extremely poor and surfacial defects are highly probable. Lubricating effects to help moulded material flow and moulded item extraction.
  • R.A. should not be washed off mechanically by moulded material flow.
  • In the case of die casting a basic property is thermal resistance at high temperature.
  • Materials technically available in die casting release agents formulation are mineral oils, special silicones, waxes and esters.
  • We need also surfactants because our products are water based.
  • The job in formulating release agent is mostly empirical and requires a lot of experience. A set of analysis the obtain a coherent picture of thermal resistance of materials commonly used was not exaustive because of the instruments limitations.
  • Die casting R.A. are water based because the water evaporation heat is very useful to cool down moulds. For this reason are used at high dilution.

Material: AE44 Magnesium
Process: Cold chamber high pressure diecasting
Weight: 23.1 lbs.
Application: Automotive mounting structure for steering, gear, sway, bar and engine roll restrictor. Originally designed as a weldment of steel stampings, the magnesium diecast structure reduced mass by nearly 9 lbs. and consolidated 15 parts into one large casting with corrosion mitigation and load distribution parts. The subframe was a CAE-driven design with stringent stiffness targets. The final design met all stiffness, durability, dimensional, and strength performance requirements, as well as requirements for elevated temperature proof load at attachment points.
