Zinc die casting services
Zinc alloys are the easiest for die casting. Ductility is high and impact strength is excellent, well suited for mass production of small parts with good dimensional accuracy. High productivity and relatively low cost.
ISO 9001:2015 and IATF 16949:2016 certified.
What is zinc die casting?
Zinc is cast with the fast-cycling hot chamber die casting process, which utilizes a component called a gooseneck that is submerged in a furnace filled with molten metal. Metal automatically enters the shot chamber through a hole in the gooseneck. A vertical plunger then seals the hole and drives the metal into the back of the die with high pressure. The part rapidly solidifies (within seconds), and the part is ejected from the tool.
Advantages of zinc die casting
1. Zinc alloy has the characteristics of small crystallization temperature range, low melting point, easy filling and forming, not easy to produce sticky mold, and can prolong die casting life.
2. Zinc alloy has high mechanical properties, can be die-cast a variety of complex, thin-wall castings can be a variety of surface treatment, especially with good electroplating, and has good room temperature performance.
3. Electrically conductive,Thermally conductive,Exceptionally corrosion-resistant,Fully recyclable.
4. High Precision and Excellent Properties.
Zinc die casting Material
Zinc Alloy 2, also known as Kirksite or Zamak 2 (ASTM AC43A), is the highest strength and hardness of the Zamak family.
Zamak 3 (ASTM AG40A), or Zinc Alloy 3, is the most widely used zinc alloy in North America and is usually the first choice when considering zinc for die casting for a number of reasons.
Zamak 5 (ASTM AC41A) or Zinc Alloy 5, is the most widely used zinc alloy in Europe.
Zamak 7 (ASTM AG40B), or Zinc Alloy 7, is a modification of Zamak 3. It is a high-purity alloy containing lower magnesium content and has a tighter impurities specification. This results in improved casting fluidity, ductility and surface finish.
ZA-8, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. ZA-8 contains approximately 8.4% aluminum and is the only ZA alloy that can be hot-chamber die cast, an important consideration when selecting a material for a component.
ACuZinc5 is an alloy researched and developed by General Motors. It is best known for its creep performance, surface hardness, and lubricity.
EZAC is a hot-chamber zinc die casting alloy with superior creep resistance, high yield strength, and high hardness.
ZA-27, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. The number 27 represents the appro
Zinc Die Casting Surface Finishing
Choose from our various surface finish options to increase corrosion resistance and add vibrant colors to your zinc die cast parts.
Oil spray
Makes a product with rich color, uniform coating, environmental protection. The surface of die castings needs to be cleaned, deoxidized and chemically pretreated.
Tumbling
Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.
Polishing
Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.
Sand Blasting
Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.
Electroplating
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
Laser Carving
The physical degeneration of the melting and gasification of the processed material under laser irradiation achieves the processing purpose.
Phosphatization
By using specific phosphating solution, a layer of phosphating film with good anti-corrosion effect can be formed on the surface of magnesium alloy
Pad Printing
Printing picture or text on another object with the carrier improves the aesthetics of the product, and increases the added value and market competitiveness.
