Miniature zinc die casting offers the highest precision at the lowest tooling cost.
Major advantages of the miniature die casting process include:
- Ability to die cast complex net shape, flash-free parts with specified features and tolerances as-cast
- No post-casting machining, with gate removal eliminated by automated degating or part-on-part deburring.
Because no trim tool is required and tools are significantly smaller, miniature zinc die cast tooling is often far less costly than conventional tooling.
Although part intricacy drives tooling cost, a simple 2 x 2 inch miniature die cast tool can cost as little as $8,500.
Long tool life is another advantage of the process, with up to 1MM cycles possible.
Finally, because of the fast cycle times, the cost of parts are generally a fraction of the cost of conventional die casting, typically costing pennies compared to dollars, making miniature die casting an excellent choice for small parts.
CWM offers zinc alloys #3, #5, #7, and ZA8, each with their own advantages. Miniature zinc die casting can economically replace other manufacturing processes such as plastic, screw machine, cold heading, and stamping, while offering greater dimensional control and lower costs.
Miniature zinc die cast components are often used “as-cast” with no further surface treatment. If required, however, CWM offers a broad range of cosmetic and functional finish options. These include corrosion protection coatings, plating, paint, or electro deposited coatings. And, when extremely tight tolerances are specified, CWM provides a complete range of CNC and conventional machining capabilities.

When production runs for a machined part increase, advanced net-shape die casting can offer substantial unit cost savings compared to part machining to specifications. Such cost reductions are being achieved for a wide variety of machined part applications in a range of alloys and part sizes. In the case of many small precision parts, the net-shape 4-slide miniature die casting process can be used to replace a brass machined part at no sacrifice in mechanical properties for significant savings at even low production volumes.
