What methods are there to prevent plastic molds from deforming during processing?

Many mold injection merchants and mold manufacturers are most afraid of plastic mold deformation. If it deforms, it will affect our normal production and cause certain harm to our interests. So, what methods can we use to prevent plastic mold deformation?

To prevent forming deformation:

The deformation of plastic molds is mainly caused by uneven shrinkage and internal stress in the mold. Therefore, we can take preventive measures as follows:

1. The number of gates should be appropriate, and each gate should be balanced

2. Choosing the correct gate shape and position can be seen based on the mold shape.

3. Prevent deformation caused by demolding

If the shrinkage rate of the material is relatively small, it should be noted that when the forming pressure is high, the plastic part is easy to stay in the mold cavity. In addition, during mold design, demolding should be carried out without deformation of the plastic parts to prevent deformation.

The design, production, and molding process of the mold should be considered based on the drawing. The key is how to ensure that the actual mold size obtained is within the size tolerance range required by the drawing, which is also a problem that designers must solve, otherwise it will affect the mold.
