CWM Wins NADCA 2012 Aluminum Die Casting AwardAluminum Die Casted Archery Bow for Children

Key aluminum handle riser component for the new compound bow developed for young archers by industry leader Bowtech, produced as a high-tech die casting by Chicago White Metal Casting, won the 2012 NADCA International Die Casting Competition in the under one lb. classification.

Specifications called for the aluminum die cast riser to meet exacting professional bow tolerances at a targeted marketing price, plus conformance to a machined “hogout” appearance with all evidence of casting gates absent.

CWM Wins NADCA 2012 Magnesium Die Casting Award

Published by:

The central housing for an advanced spotting scope by Leupold & Stevens, world’s leading producer of high-performance sports optics, is designed to offer the sharpest, brightest viewing at distances greater than possible with premium binoculars. Impressive housing specifications called for lightweight portability, absolute ruggedness and 100% waterproof construction— nitrogen filled and guaranteed for life.  The scope housing requirements were met with an ideal solution – die casting magnesium (Mg) parts in order to fill the tall order.  The use of a magnesium alloy for die casting allows the spotting scope housing to be as lightweight as possible while still being able to withstand outdoor elements.

Die Cast Magnesium Housing for a Leopold Spotting Scope

The housing is produced by CWM as a hot-chamber, high-precision die cast magnesium housing, weighing just 8.0 oz. (226.8 gm) with thin-wall sections as narrow as 0.039 in. (1.0 mm). It received an award in the 2012 NADCA International Die Casting Competition in the over .5 lb. classification.

Thixo-to-Hot Chamber Mg Die Cast Conversion

Published by:

After hearing their Asian thixomold supplier say, “We don’t want your business because your volumes are too low,” a high-end producer of electronics with multiple applications for magnesium castings was forced to hunt for a second Asian source to continue manufacturing parts using the existing process.

They found a new thixomold supplier and shortly after moving production, a set of issues began to surface. Getting parts on time became problematic. Stretched lead times resulted in inventory shortages, and with parts coming from Asia they had the added stress of import issues compounding late deliveries. Production was expedited, but that resulted in high set-up fees. In an attempt to leverage the set-up fees, quantities for production runs were increased. However, this resulted in excess inventory, causing yet another set of problems.

New Report on OEM Sourcing’s Return to U.S.

Published by:

A seven-page White Paper has been released by the North American Die Casting Assn. (NADCA) on the resurgence of manufacturing sourcing to U.S. suppliers as reported in major consulting firm studies and by industry and business publications. The overview cites examples of “onshoring” that range from Fortune 500 companies to smaller manufacturers producing toys.

The review notes that North American custom die casters are participating in this trend, with nearly a quarter of NADCA members reporting new gains from die casting projects previously sourced offshore. Factors responsible for recent OEM decisions to return to U.S. suppliers, a trend that is expected to continue, are discussed in detail.

This latest NADCA report is an updating of the research study, “Hidden Costs of Offshore Sourcing,” which NADCA conducted in conjunction with the U.S. Dept. of Commerce in 2004. (A summary of the ’04 study is available to DC2 Design Center registrants in the Center’s “Buyer Resources” section.

The new White Paper is available here in PDF format forimmediate download.

NADCA 2011 Die Cast Design Award to CWM

Published by:

The design engineering teams from CWM and Cast Products collaborated on a new die cast product, a conversion from plastic to zinc. The results were an innovative product design and an award from the North American Die Casting Association for the design’s ingenuity,
cost savings and overall quality.

The award was given in the “under 6 oz. non-electroplated” category and was presented at NADCA’s 2011 Die Casting Congress held in Columbus, Ohio.

Converted from ABS plastic to zinc die casting, the product’s durability and performance was greatly enhanced. The casting is used to hold a camera onto an interactive whiteboard. The camera picks up infrared light from the whiteboard and sends it to a computer. To accurately capture this, the camera had to be rigidly held in place. High product demand created an aggressive timeline to produce parts. The design teams met the challenge and samples were approved for production in just 5 weeks.
