Yesterday, a fan sent me a message, told me that his die casting production of light fittings, always deformed, have you ever encountered deformation problems in die casting? So how can we improve the deformation of die casting?
First of all, we must control the cooling speed of the die casting, if the cooling speed is too fast, it is easy to crack, and the cooling speed is too slow, it is easy to deformation.
Secondly, we should pay attention to the structural design of die-casting parts, avoid designing structures that are easy to deform such as sharp corners and thin walls, and try to make the shape of the parts symmetrical.
The third is to choose the die casting material reasonably, the heat treatment performance of the material has a great impact on the deformation, so the suitable material should be selected. To correctly select the three parameters of the die casting process, such as injection speed, injection specific pressure, pressure holding time, etc., should be adjusted according to the actual situation.
