Zinc Die Casting Moulding And Mold Manufacturing

Zinc Die Casting Moulding And Mold Manufacturing

The mould or die can be divided into two sections that mounted securely in the machine, one of them are moveable while another part is stationary. In the beginning, two die halves are clamped together tightly by the die casting machine. Then inject the molten zinc into the mould cavity, where it hardens rapidly. After the zinc alloy castings become solidified, separate from the mold halves, and the casting is ejected. The complexity of mold design is according to the desired zinc casting parts, simple or complex metal castings can be made with PTJ zinc casting service.PTJ is one of the best mold makers in China, offering mold manufacturing solutions for every industry. We own advanced techniques, highly skilled staff that employ superior tooling and high pressure die cast processes to ensure that the mold parts are of the cheapest price and highest quality. Whether you need rapid tooling, mass production mold making with tight tolerances, our team of experienced specialists can offer a cost-effective solution at each stage. Contact our expert team and get a price for your tooling/mold making service, we will quote you a die casting and mold manufacturing price in 24 hours!

  • - According to the materials used in the product, the shape and accuracy of the product and other indicators, the process is analyzed and the process is determined.
  • - Determine the position of the product in the mold cavity, analyze and design the parting surface, the overflow system and the pouring system.
  • - Design the core assembly and fixing methods of each activity.
  • - Design of core pulling distance and force.
  • - Design of ejector mechanism.
  • - Determine the die-casting machine, design the mold base and cooling system.
  • - Check the relative dimensions of the mold and die-casting machine, and draw the process drawing of the mold and each part.
  • - Design completed

Our Experience For Zinc Die Casting Material

Traditional die-cast zinc alloys are No. 2, 3, 5, and No. 7 alloys, and No. 3 zinc alloy is currently the most widely used. In the 1970s, high-aluminum zinc-based alloys ZA-8, ZA-12, and 2A-27 were developed.

Commonly used zinc alloy applications:

  • - 3": Good fluidity and mechanical properties. It has the best combination of mechanical properties, casting properties and economy. It is used in castings that do not require high mechanical strength, such as toys, lamps, decorations, and some electrical devices.
  • - 5": Good fluidity and good mechanical properties, high wear resistance.
  • - Used in castings that have certain requirements for mechanical strength, such as auto parts, electromechanical parts, mechanical parts, and electrical components.
  • - 2": Used for mechanical parts that have special requirements for mechanical properties, high hardness requirements, and general dimensional accuracy requirements.
  • - zA8: Good fluidity and dimensional stability, high creep resistance.It is applied to die-casting workpieces with small size precision and high mechanical strength requirements, such as electrical devices.
  • - For example, ZA-3 is used for exterior parts of mobile phone accessories such as face shells. ZA-8 is better; ZA-8 and ZA-12 are better for internal parts such as brackets.
