Zinc Alloy Casting Services

Zinc can be cast to precision tolerances, have thinner wall sections, complex shapes and much longer tool life. Aluminum alloy casting China has the capacity to produce aluminum alloy castings with a wide variety of finishes. Our goal is to deliver your cast product exactly to print specifications. Although aluminum cast parts have a larger demand in the OEM marketplace, our ISO9001 certified manufacturing facility has several zinc die casting machines. These machines allow us to supply engineered products that range in size from several grams to nearly 45 pounds.


When to use Zinc instead of Aluminum alloy Cast Parts?


In addition to our first-class aluminum alloy casting machines, our seasoned QC engineering staff interfaces with warehouse production to detect any problems and inspect the product for any defects. Zinc alloy has improved surface toughness and hardness making it an ideal alternative to machined, pressed, stamped and fabricated items. Zinc alloy parts are known for their toughness over competing materials and processes. The overall yield strength of this die casting material is 15 times more than aluminum alloy casting and magnesium alloy casting. The alloy strength is a primary reason why the zinc die casting process is commonly used for many handles, electro-mechanical applications and other housing types.


Alloy Zamak-3 is currently the most popular alloy and widely used. Zamak 3# has good fluidity and mechanical properties, and can be applied to castings that do not require too high mechanical strength, such as toys, lamps, decorations, some electrical components, furniture parts, furniture handles, etc., zamak 5# has good fluidity and mechanical properties, can be applied to auto parts, mechanical parts, electrical components, etc.
