Zinc Die Casting
Components

Prototyping

Zinc die castings can be prototyped using several techniques, depending on specific properties of interest. One popular prototyping method is to machine the shape from a solid piece of zinc alloy. This method is especially useful when a limited number of parts with relatively simple features are required. It should be noted that mechanical properties of machined zinc components will be inferior to those of a like shape die cast part.

Types of Die
Casting Machines

Miniature Casting operates conventional as well as four-slide die casting machines with single- or multi-cavity dies. We have the capabilities to manufacture components up to 4 inches in any direction, and under 6 ounces in weight.

Die casting is the most accurate of the casting processes. The reason for this is that the zinc alloy is molded in steel dies machined to very tight dimensional tolerances.

Design Points to Remember

  • Elimination of machining is one of the greatest benefits of the die casting process and every effort should be made to take advantage of the precision of miniature die casting.

Design’s effect on all secondary operations (including machining and finishing) should be considered before finalizing the design, so that the die casting process will provide the maximum benefit.

Coating Systems

MCC, as a full-service die casting company, provides designers and engineers assistance in obtaining the proper coating finish in order to achieve the desired functional or cosmetic results. When selecting a top-coat system, the designer must fully understand the properties of the casting and coating as well as the service conditions the product will be expected to withstand. Many engineering applications do not require surface coating of zinc castings. Their excellent casting and material properties often enable them to be utilized as-cast. Coatings and finishes are specified to enhance the properties of castings by providing a decorative finish, increasing corrosion resistance, and improving engineering properties.
The coating systems available for zinc castings offer a wide spectrum and are most often classified into three categories: chemical, metallic and organic finishes.
