Zinc Miniature Die Casting. In miniature zinc parts designing, the zinc die casting process has significantly evolved. Zinc miniature die casting has produced tiny geometrically designed complex parts with several features, great precision, thin walls, multi cored holes, and a flash-free, sculptured shutoffs.
Some companies have been producing miniature zinc die casting for several years. Using their four-slide, high-speed machines, which are microprocessor-controlled, they were able to offer their customers, engineered products, tool designs, rapid prototyping, maintenance, and manufacturing.
According to experts, miniature designs require a special approach to design and engineering. To be able to create a miniature zinc die casting design a designer must put all the disciplines together on the part design, tooling, and processing. There are things that are needed to consider in designing a zinc miniature die casting. The design should conform to the minimum thickness of .014 inches.
Die Casting Tooling layout should match the geometry to assure proper fill and gating, ability to overflow thin wall sections, proper tool control and half registration, ability to eject part consistently, ability for runners to degate, parting lines optimal location and proper cavitation. The designer should also analyze the operations for secondary options and operations for sequencing.
To ensure success, it is important to disclose the post-cast forming operations. Consider the effect of plating on features and tolerance if the parts require plating for cosmetics or corrosion protection. These are only some of the few things that are needed to consider in zinc miniature die casting. This type of casting requires deeper considerations on the die cast supplier earlier before the start of the process.
