Die casting of auto parts. The factory has strong technical force, strong ability to develop new products, perfect detection means of automobile parts die casting technology, automobile parts die casting company regards quality as life, takes science and technology as the guide, constantly launches new products. Die casting of automobile parts: Molten metal filling at high speed under high pressure and solidifying under pressure. Methods of making.
1. Advantages: Good casting quality, high production efficiency and good economic benefits
2. Disadvantages: Die-casting mold has complex structure, high manufacturing cost and long production cycle; liquid metal filling speed is high, solidification is fast, feeding is difficult, and it is easy to produce small porosity and shrinkage defects in castings.
3. Application: Large-scale production of small and medium-sized non-ferrous metal alloy castings, of which zinc alloy, aluminum alloy die castings are the most widely used.
Die Casting of Automotive Parts
1. The theoretically calculated clamping force must be smaller than the nominal clamping force of the die casting machine.
2. The theoretical calculation of the chamber capacity should be less than that of the nominal chamber of the die casting machine.
3. The theoretical calculation of die opening force and pushing force should be less than the maximum force and pushing force of the selected die casting machine.
4. The total thickness of the die should be greater than the minimum closing distance of the die casting machine.
5. The maximum distance of die casting should be greater than the total thickness of die and the total height of product.
6. The template size and hole position of the die-casting die-casting machine should be in accordance with the fixed plate size and hole position of the die-casting machine.
7. The exterior dimension of the die and the maximum size of the exterior mechanism extending the die should not touch the tie rod of the die-casting machine, otherwise it will affect the normal operation and use of the die-casting machine.
Investment casting of automobile parts die casting: also known as wax loss casting. Mold (wax pattern) is made of fusible material such as wax. Several layers of refractory coatings are coated on the pattern to make the shell. Casting method of the shell with fused pattern can be poured after calcination at high temperature.
1. Advantages: Castings with good quality and complex shape can be poured, and castings of various metal materials can be produced.
2. Disadvantage: The operation process is complex, the production cycle is long, the cost is high, and the bigger parts can not be cast. Usually they are under 20 kg.
3. Application: Investment casting can be considered for parts with complex shape and difficult machining. At present, the production of carbon steel and alloy steel castings is the most widely used.

How to Choose Die Casting Machine
1. Selection of materials for die castings:
Copper, aluminium, magnesium, zinc, lead, tin and other alloys,
2. The shape and size of die castings.
The maximum projection area and injection specific pressure are used to calculate the clamping force (clamping force) of the die casting machine.
3. Weight of die castings:
Fourth, according to the accuracy of die casting and internal quality (large precision, thin wall, pressure resistance, stress) selection: - This is the most important is the performance of the injection system.
