Although die casting component design can be complex, following a few fundamental principles will help minimize die casting issues during the production phase and subsequent performance in the end product. CWM created these comprehensive guidelines to aid you when designing for die casting, whether it is for aluminum, magnesium, or zinc alloys. Each design guide incorporates over 75 years of CWM’s die casting knowledge into a condensed guide for the OEM product design engineer.
Also included are papers from the North American Die Casting Association (NADCA) which can assist OEMs in optimizing die casting component design, specifications and overall die cast production processing.
|Product Design for Die Casting
|NADCA: Coordinate vs Geometric Dimensioning Intro
Presentation of "Standard" and "Precision" tolerances as outlined in the latest NADCA Product Standards Manual, plus outline of Coordinate Dimensioning vs the advantages of the GD&T framework for specifying die cast parts.
|NADCA: Die Cast Production & Finishing Checklists
Key factors in specifying the production and surface finishing of die cast parts, based on NADCA Product Standards Manual guidelines. Helps assure clearer communication between OEM purchaser and die caster. (2015)
|NADCA: Pointers for Designing Die Castings
Die castings offer exceptional design freedom while at the same time achieving excellent mechanical properties for a product component. Selected features should be designed to enhance casting quality and avoid unnecessary casting costs. This article offers details on key points to consider in optimizing the cost-performance equation for a die cast part.
|NADCA: Product Standards Manual Overview
Illustrated condensed overview of the basic contents of the die casting industry's authoritative "Product Specification Standards for Die Castings" reference manual, as originally established in 1997.
