Warpage and deformation of injection products are very difficult problems. Mainly from the mold design to solve the problem, and the forming conditions of the adjustment effect is very limited. The causes and solutions of warpage and deformation can refer to the following items:
1) When the deformation is caused by the residual stress caused by the forming conditions, the stress can be eliminated by reducing the injection pressure, increasing the mold temperature, increasing the ... Read more
According to the causes of bubbles, the solutions are as follows:
1) When the wall thickness of the product is large, the cooling speed of the outer surface is faster than that of the center part. Therefore, with the cooling process, the resin in the center part shrinks and expands to the surface, resulting in insufficient filling in the center part. This is called a vacuum bubble. The solutions are as follows:
a) According to the wall thickness, determine the reasonable gate ... Read more
If it is a matter of manufacture, it is important to bear in mind that various topics are always related in this field, since many of the processes always go hand in hand with others and especially when it comes to additive manufacturing, a procedure that has become so popular during the last years.
