Where die casting makes "cents"
include sand and investment casting of zinc, magnesium, and aluminum alloys, permanent mold casting for aluminum and zinc alloys, and semisolid-metal (SSM) processes for both magnesium and cold-chamber zinc alloys. Powdered metal is yet another option for producing aluminum and magnesium components

Die casting makes short work of small-lot parts
Switching from machined RF shields to precision die castings let Anritsu Co., Morgan Hill, Calif., cut costs in its Site Master series of analyzers, which are made in small lots. The company estimates payback on its die-casting investment will take only six months. "Most of these components

Pigment Dispersions Using Sonic Techniques
, casting of methacrylates, electrocoating of metal parts, etc. The balance of this report will be devoted to presenting some of the systems and the special contribution Sonolation has to make. Since many of these systems are more or less unique, at least in the eyes of the manufacturer, we will not bore

A better way to cast aluminum
casting process helps minimizes secondary machining operations and spin balancing processes. Sand casting involves temporary molds made from metal or wood patterns. Consequently, up-front investment for tooling is low, but per-part prices are usually higher than permanent-mold castings. Conversely

NET-SHAPE metal parts in one shot
fills, voids, and porosity are possible. Volumetric shrinkage of wax and metal during cooling mostly determine the degree of flatness in an investment casting. Shrinkage at the part center is termed "dish" shrinkage, drip, or outofflat. Dish is controllable with special techniques but cannot

MICRO: Brainstorming Team
Working in the wet cleans group at International Sematech in January 2000, Pat Lysaght was casting about for a method his team could use to quantify its edge wraparound cleaning technique. The senior member of the technical staff approached two colleagues in the consortium's analytical lab

Cost-conscious molding
a permanent graphite mold to rapidly produce 300 to 20,000 parts. The parts are from ZA-12, a zincaluminum alloy (approximately 11% aluminum) that's harder, stronger, and more durable than brass, bronze, plastic, or aluminum alone. A knowledgeable casting house can use this molding technique to go
