Selection of high-pressure die-casting machine needs to be comprehensive consideration of a number of factors, including technical parameters, process requirements, material properties and equipment performance and so on.
By carefully evaluating these criteria, you can select a high-pressure die casting machine that meets your production needs and ensures high-quality castings.
Selection Criteria for High Pressure Die Casting Machine
Technical Parameters and Process Requirements
Injection Pressure: High-pressure die casting requires high injection pressure to ensure that the molten metal completely fills the mold cavity and overcomes the resistance of gases. For example, aluminum die casting typically requires an injection pressure of 90 MPa.
Mold Design: The design of the mold directly affects the quality of the die-casting parts and production efficiency. The mold needs to have an effective cooling system to shorten cycle times and ensure that the mold material can withstand high temperatures and pressures.
Chamber Capacity and Locking Force: The chamber capacity must meet production requirements, while the locking force must exceed the product of the injection pressure and the projected area to prevent mold cracking or flash formation.
Material Selection
Alloy Type: Different alloys have distinct performance characteristics. For example, aluminum, zinc, and magnesium alloys are suitable for cold chamber die casting, while copper and lead-based alloys are appropriate for hot chamber die casting.
Sustainability and Cost-Effectiveness: When selecting materials, it is necessary to balance quality, cost, and environmental impact. For instance, although zinc alloy is more expensive, its superior properties make it more attractive in certain applications.
Equipment Performance and Stability
Mechanical Performance: The selected die-casting machine should feature high precision, high rigidity, and low maintenance frequency. For example, the HDC series cold chamber die-casting machines improve equipment stability and reliability by optimizing the hydraulic system and injection unit design.
Operational Safety: The equipment should be equipped with safety devices, such as hydraulic safety valves and emergency stop buttons, to ensure the safety of operators.
Intelligent and Automated Features: Modern die-casting machines typically come with real-time monitoring systems and intelligent quality management systems that can automatically detect and reject defective products, thereby improving production efficiency.
Economic and Efficiency Considerations
Production Efficiency: High-pressure die-casting machines should have the ability to fill and cool quickly to shorten production cycles and increase output. For example, optimizing process parameters (such as injection speed and holding time) can significantly enhance production efficiency.
Maintenance Costs: The maintenance costs of the equipment are also an important factor in selection. For instance, HTS offers a full-system service, including maintenance of the injection plunger, oil circuit, and ring heaters, which helps reduce long-term operating costs.
Environmental and Sustainability Factors
Energy Efficiency: Since die-casting is a high-energy-consuming process, selecting energy-efficient equipment can reduce production costs and minimize environmental impact.
Material Recycling and Reuse: Choosing equipment and processes that support material recycling and reuse helps achieve sustainable development goals.
Other Considerations
Supplier Support and After-Sales Service: When selecting equipment, it is crucial to consider the supplier’s technical support capabilities and the quality of after-sales service. For example, suppliers should offer at least a 5-year warranty and have a comprehensive training and technical support system in place.
Customization Needs: For complex parts or special applications, customized equipment or specialized functional modules may be required, such as high-flow quick-change valves or high-performance servo motors.
