What are the main defects of Motorcycle engine cover die casting?
Answer: There are undercasting (not full of material), cracks, deformation, cold separation, cold lines, shrinkage, pores (sand holes), mechanical strain, sticky mold strain, delamination, wrong mold, slag inclusion, surface cavitation , Blistering, fleshy, lack of meat, etc.

What is the temperature of the aluminum alloy liquid suitable for die-casting production?
Answer: 650℃~720℃

What are the characteristics of die casting production?
Answer: (1) High production efficiency, mechanized or automated production can be realized;
(2) Good product quality: A, high dimensional accuracy, high surface finish; B, good mechanical properties; C, good interchangeability; D, clear outline, thin and complex castings, patterns, patterns, characters, etc. can be obtained High definition
(3) Good economic effect: A. Excellent economic indicators; B. Low cost of die castings; C. Can be used as a combination of parts;
(4) Die-casting equipment and molds have high investment costs and are not suitable for small batch production.

What aspects are involved in the design of die castings?
1. That is, the requirements of pressure casting on the shape and structure of parts;
2. Process performance of die castings;
3. The dimensional accuracy and surface requirements of die castings;
d. Determination of parting surface of die-casting parts; part design of die-casting parts is an important part of die-casting production technology. The following issues must be considered when designing: selection of mold parting surface, gate opening, selection of ejector position, casting The shrinkage of the casting, the guarantee of the dimensional accuracy of the casting, the prevention of the internal defects of the casting, the relevant requirements of the casting hole, the relevant requirements of the shrinkage and the size of the machining allowance, etc.;

What are the design principles of die castings?
a. Correctly select the material of die castings,
b. Reasonably determine the dimensional accuracy of die castings;
c. Try to make the wall thickness evenly distributed;
d. Add craft round corners at each corner to avoid sharp corners.

How are automotive casting products manufactured?Automotive parts are manufactured using different techniques. The main processes used in production have to provide efficient and lightweight results. To achieve these results, the following processes are maintained.
High pressure die castingThis process produces products with less porosity and more perfection. High pressure die casting is the most widely used process in the manufacturing of automotive castings. It makes use of pressure techniques to fill the mold with molten metal and the ejection of a set part in the mold. The pressure techniques produce complex parts and reduce the need for more parts in the assembly.
