Four common problems in blow molding processing products

Blow molding processing inevitably encounters certain problems in the daily production process, mainly because the products produced often have some defects. Today, the editor will introduce four common problems of blow molding processing products, mainly divided into the following four aspects:

1. Insufficient attention. This situation is often caused by inaccurate adjustment of the screw position at the beginning, or by low melt temperature, insufficient mold temperature, or low secondary injection pressure and rate. If it is caused by the above two problems, adjustments can be made.

2. The uneven color of the product is often caused by dead corners in the mold, prolonged residence time of raw materials in the barrel, uneven plasticization, and other issues. 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 materials flowing through early cooling, so it is important to control the temperature during the blow molding process.

4. Demoulding deformation. This is very easy to understand, often caused by multiple factors such as deformation during the trial molding stage, uneven raw materials, incorrect angles, etc. At the same time, if the cooling time is very short and the model does not cool properly before peeling off, it can also lead to deformation.

The above is an introduction to the "four common problems in blow molding products". Blow molding is a relatively delicate industry, especially for plastic parts. If there is slight discomfort, it can lead to installation problems. Therefore, these four problems should be avoided as much as possible during processing, and precision should be achieved as much as possible.
