ZN Process

The IOSSO-ZN Process specifically transforms every-day soft zinc alloy parts into hard, extremely wear resistant materials. The patented process bonds directly with the zinc alloy surface to provide a hard outer case not simply a surface deposited coating. A new diffused surface is the result which is extremely hard and tough. Designers can now incorporate the die cast technology with the IOSSO-ZN Process to produce economical components with excellent strength and precise, close tolerances.

Zinc diecasting is probably the fastest, most convenient one-step manufacturing process to produce complicated metal parts. Precision close tolerance casting eliminates most machining operations. Instead of using expensive brass, iron and specialty steel castings or forgings, the IOSSO-ZN processes put conventional zinc die castings into contention to replace many of these expensive previously used alloys.
