Why Die Casting

Why Zinc Casting?

Metal castings, in general, are found in 90% of all finished products such as door knobs and hinges, hand-held razors, zippers, automobiles, cell phones, etc. In fact, die casting is frequently referred to as the fast way to go from raw material to finished product. The process occurs when molten metal is injected into the hollow space of a steel die. While there are a number of metals one can use to produce a die casting, the production cycle is the fastest and produces the strongest, most durable part, when a zinc alloy is used. For instance, a zinc die cast mold will produce at optimum over one million times, while the same die cast mold using aluminum alloy will only produce about 100,000 times.  When producing a zinc die cast, there are two types of machines used: the conventional hot chamber and the high-speed, multi-slide machine. At Hoffman, we use multi-slide machines which allow us to produce high volume jobs involving very close tolerance, high complexity, while producing minimal waste. These four key components, coupled with the 100% waste recyclable nature of zinc, present a low cost solution.

Why Aluminum Castings?

Aluminum Castings are beneficial due to their high strength to weight ratio and the high volume of near net shape parts. Hoffman Die Cast specializes in using K-Alloy. 

Why K Alloy? 

K-Alloy is a highly corrosion resistant Aluminum die casting alloy with superior properties. K-Alloy is beneficial for applications where harsh environments cause corrosion, where chromate or other coatings are undesirable and when designs call for better heat dissipation. This means parts do not require a coating; reducing the cost for our customers.
