Blow molding will inevitably encounter certain problems in the daily production process. The main reason is that the products produced often have some defects. Today, the editor will introduce four common problems of blow molding products to you, which are mainly divided into the following four aspects:

1. Short injection. This situation is often caused by inaccurate screw position adjustment at the beginning, or because of low melt temperature, insufficient mold temperature or low secondary injection pressure and rate. If it is caused by the above two problems, just adjust it.
 2. The color of the product is uneven. This situation is often caused by the mold having dead corners, the raw material staying in the barrel for too long, uneven plasticization, etc. These situations can be gradually eliminated.
3. There are wrinkles at the far end of the gate. This situation is often caused by the mold being too large and the raw material flow cooling too early, so the temperature must be handled well during the blow molding process.
4. Demolding deformation. This is very easy to understand. It is often caused by multiple situations. For example, deformation in the mold trial stage, uneven raw materials, and unequal angles will cause this problem. At the same time, if the cooling time is very short, the mold is not cooled well before demolding, which will also cause deformation.
 
The above is an introduction to the "four common problems of blow molding products". Blow molding is a relatively delicate industry, especially for plastic parts. If there is a slight discomfort, it will lead to problems such as installation. Therefore, the above four problems should be avoided as much as possible during processing, and be as precise as possible.
