Precision Die Casting Die FactoryAboutDie casting structureWhat are the control elements, and what are the control system elements for the die casting structural parts of the car body.
1. The coordination between the product design and the die-casting drawing of the body structure, and the selection of alloy materials involved in the product drawing, are related to the casting process and its reasonable feasibility. The die-casting performance of the die-casting alloy should be evaluated in accordance with the astm b85 aluminum alloy technical standard, and the stress load area of the important components of the die-casting alloy structure must be clearly marked to provide a basis for the cutting and sample inspection of the die-casting, and ensure the quality of the die-casting parts.
2. In casting and mold manufacturing, design the structure of drainage system and mold flow analysis, design the process of die casting die, design the pouring system, develop the thermal balance layout of the mold cooling and heating control system, and design a key gate section and proportion, and other technical research schemes should be reasonable, effective and feasible, and ensure the quality of the enterprise's products in the high stress area. If necessary, press locks can be selected appropriately by improving the projected area Tonnage of mould force and management of vacuum die casting production capacity Span>
3 Precision Die Casting Mold FactoryAboutDie casting structural partsWhat are the control elements, castingDie casting structureThe high plasticity requirement of general mechanical properties is a prominent feature, and the selection of alloy chemical composition should not only fully consider the service performance, but also take into account the molding requirements of die castings and the uniform development of wall thickness.
Precision Die Casting Mold FactoryAboutDie casting structureWhat are the mechanical property requirements of the control elements: tensile strength≥ 250Mpa, elongation ≥ 10. According to the performance requirements, combined with the chemical composition of GM-1 and the characteristics of the structural parts in the product drawing, multi-component batch tests are carried out. The silicon element close to the eutectic composition is selected to meet the needs of thin wall and complex shape of die casting products. Another feature of silicon addition is that recent microscopic analysis shows that silicon element is used in the solidification process of castings Expands and reduces shrinkage. However, the tendency of thermal cracking generated by other elements is balanced, and the casting stress is also restrained. However, silicon reduces the hydrogen solubility in liquid alloys span>
