Haichen cold chamber die casting machine spare solid Plunger Piston head parts
| Die casting machine Piston head |
The mechanical activation head is one of its core components, the main cost is the high mechanical strength, the molten metal is inserted into the mold cavity, and the number of operational parts is directly determined. |
Haichen Die Casting Machine Piston Head based on the provided information:
1. Cold Chamber Die Casting Machine (e.g., C-Series) Injection System
- Haichen's cold chamber machines use multi-stage injection control (slow injection, first fast injection, second fast injection, and intensification stages).
- The injection plunger (analogous to the piston head) is precisely positioned via a magnetic linear encoder.
- Critical components, including the plunger, are designed to withstand high pressure (up to 1600 bar) and temperatures (600-700°C for aluminum/magnesium alloys).
- Material: High-quality alloy steel or specialized cast iron is likely used for the plunger head, supported by hydraulic components from German/Japanese brands (e.g., Rexroth, YUKEN).
2. Hot Chamber Die Casting Machine (e.g., HCH-Series) Injection Mechanism
- The plunger head is immersed in molten zinc/lead alloys, requiring corrosion resistance and thermal stability (operating at 400-500°C).
- Hydraulic systems (Vickers, Yuken) ensure rapid response and stable pressure, implying the piston head must handle high-frequency cycles without deformation.
3. Material & Manufacturing Standards
- Haichen adheres to JB/T8083-2000 (Chinese industry standard) and EU CE safety certifications.
- Critical components undergo FEA (finite element analysis) and CAD/CAE optimization, ensuring structural integrity under extreme conditions.
- While exact piston head material grades are unspecified, components exposed to molten metal are confirmed to use heat-resistant alloys with surface treatments (e.g., nitriding) for wear resistance.
4. Maintenance & Reliability
- Regular inspections of hydraulic seals and lubrication are recommended to prevent piston head wear.
- Haichen supplies replaceable wear parts (e.g., seals, piston assemblies), confirming the piston head is designed for easy replacement.
Haichen's piston heads prioritize durability under high thermal/mechanical stress, likely using high-strength alloy steel or specialized cast iron. Cold chamber designs focus on aluminum/magnesium compatibility, while hot chamber models emphasize corrosion resistance for zinc/lead alloys. For specific technical parameters (e.g., dimensions, material grades), users should consult product manuals or contact Haichen directly.
