Requirements of die casting manufacturers for the quality of their products

Views: 0     Author: Site Editor     Publish Time: 2021-10-25      Origin: Site

The die casting process is an important technology in modern industry. It makes it possible to produce metal parts with complex shapes, well-defined contours and thin walls and deep cavities. Because the molten metal remains highly fluid at high pressures and speeds, it is possible to obtain metal parts that are difficult to process by other processes. The product we would like to introduce today is related to the die casting process. aluminum alloy die casting is the main product of die casting manufacturer and it plays an important role in many fields.

What are the technical requirements of die casting manufacturers?

The quality and technical requirements of die casting manufacturers are very high. First of all, the die casting should be checked for all dimensions and surface quality in accordance with the drawings and the requirements put forward by the customer. aluminum alloy die casting frontal surfaces are not allowed to have cracks, fissures, under-casting, shrinkage and any penetrating defects. At the same time, although the accuracy of die casting is relatively high, but worse than plastic, and the drawing force than plastic, usually the structure can not be too complex, if necessary, the complex parts should be disassembled.


What are the common defects of aluminium alloy die casting?

Casting cracks

This is a crack that forms at higher temperatures and tends to occur in alloys with greater volume shrinkage and in castings with more complex shapes. The main causes of this are poorly designed castings with sharp corners and excessively wide variations in wall thickness. To avoid this, die casting manufacturers will improve the structural design of the casting to avoid sharp corners and to achieve a uniform wall thickness with a smooth transition.

Shrinkage

Shrinkage is also a problem that can easily occur during the production process. Aluminum alloy die casting shrinkage generally occurs near the inner sprue in the thick part of the root of the fly riser, the thick and thin wall transition and has a large plane of thin wall. For this situation, die casting manufacturer needs to correctly grasp the pouring speed to avoid the involvement of gas.

Aluminum alloy die casting is not suitable for small batch production, the main reason is the high manufacturing cost of die-casting aluminum, die-casting aluminum machine production efficiency, small batch production is not economic. We recommend that you take a closer look at the advantages and disadvantages of aluminium alloy die casting before you buy it.


The main advantages of aluminium alloy die casting

The dimensional tolerances of die castings made by die casting are very tight and the surface accuracy is very high. aluminium alloy die casting can be assembled in most cases without further machining. At the same time, the dimensional consistency and interchangeability of aluminium alloy die casting reduces operating costs to a certain extent.


With the continuous development of the aluminium alloy die casting industry, the renewal and innovation of various generations of products requires a wide range of aluminium alloy die castings with complex shapes and high precision requirements, ltd. founded in 2004, we moved to xiegang town at the end of 2017 for business and development request.
