How to set the under-voltage protection of injection molding machine

To switch the position of low voltage protection, generally look at the distance between the guide pillars of the mold, and start to switch the low voltage when approaching the guide pillars. The lower the low pressure, the safer it is, as long as the mold can be closed. Generally not higher than 50% of the maximum clamping force.

According to the size of the mold, it is good to clamp the mold smoothly with minimum pressure. In the case of uncertain pressure, the low-pressure locking pressure can be gradually increased from small to large to ensure that the mold is protected.

Low voltage protection means that when there is something on the surface of the mold, it will automatically open the mold in order not to damage the mold. This process is under-voltage protection.

Extended data:

There are three main aspects in the evaluation of plastic products.

The first is the appearance quality, including integrity, color, luster and so on.

Second, the accuracy between size and relative position;

The third is the physical properties, chemical properties and electrical properties corresponding to the use. These quality requirements have different scales according to the application of products.

The defects of the product mainly lie in the design, manufacturing accuracy and wear degree of the mold. But in fact, technicians in plastic processing plants often encounter such a dilemma: using technical means to make up for the problems caused by mold defects has little effect.
