Core Advantages
Dimensional Stability
Zamak 5 material has a low coefficient of thermal expansion, resulting in minimal dimensional change after processing. Combined with three-dimensional coordinate measurement, critical dimensional errors are controlled within ±0.03 mm, ensuring assembly consistency.
Dense Structure
Utilizing 125 MPa high-pressure die casting, integrated cooling channels in the mold regulate the solidification rate, and metal-filled components, the casting density exceeds 98%, minimizing internal defects.
Precision Machining
Critical areas are CNC-drilled and tapped, achieving positioning errors of less than 0.02 mm. Combined with a closed-loop measurement system, this ensures high-precision alignment with the overall vehicle structure.
Surface Treatment
The surface is sandblasted, pickled, then nickel-plated or spray-coated. The coating thickness is controlled at 12–15 microns. Salt spray testing lasts for at least 96 hours, making it suitable for corrosive environments.
Material Selection
-It is extremely dimensionally stable in nature and non-cytotoxic in nature, thus most suitable to most motor part uses. Zamak 5 is slightly hard in strength because an additional quantity of copper has been included in it and is employed in motor part production where motor part specification requires superior physical qualities.
Die - Casting Process
- Mold Design: Critical design is necessary in this situation. Die-casting temperatures and pressures have to be withstood by this mold. It is created in accordance with precise shape and size specifications of the part in the car, including factors like channels to control solidification speed in zinc alloy.
- Melting and Shotting: The zinc-aluminum alloy is heated between 400 to 450°C in most uses. When heated, it is injected in to die cavity by means of high-pressure (generally between 10 to 175 MPa). High-pressure is used to fill every section of die to achieve an accurate part with intricate detailed patterns and improved surface finish.
Post - Processing
- Trimming: Trim off the excess material (such as flash) around the part after die-casting is completed. This is most often achieved by means of presses or trimming tools.
- Surface Treatment: Surface treatments have been used to beautify zinc die-casting alloy to render it more corrosion resisting in nature. Treated commonly used treatments are chrome plating or nickel plating by process of electroplating, painting, and powder coating.
- Machining: Certain motor vehicles have machining carried out in addition to drill, tap, or to obtain desired dimensional tolerance to form certain features such as mounting holes.
why choose us?
- Dimensional Inspection: All the parts get inspected by accurate measuring tools in the form of coordinate measuring machines (CMMs) to validate these have been manufactured to dimensional tolerances prescribed.
- Non-Destructive Testing: X-ray testing and ultrasonic testing methods are employed to check internal defects in the die-castings in the form of cracks or porosity.
- Mechanical Testing: Production sample is employed to conduct tensile strength testing, testing of hardness, and testing by impact to ensure part is in conformance to performance standards in these.
