What should be noted during plastic injection molding operations?

I. Adjustment of Production Process

First, check whether the process parameters are the same as those of the actual model, materials and molds.

2. When inputting process parameters simultaneously, the first draft should be produced at a slightly reduced pressure and speed, and then gradually adjusted (based on the product quality ratio).

3. When there are no process parameters, it is essential to understand the mold structure, the amount of glue, and other adjustments. Blind adjustment is strictly prohibited. Pay attention that if the special mold is not glued enough, it will stick to the mold. If there is too much glue, it will stick.

Ii. Operator Production:

1. Check whether the machine's safety adjustment is safe;

2. Whether the operator is familiar with the quality standards of the products to be produced before operation;

3. The plastic injection molding processing factory explains that the processing method must be correct. For instance, the sprue position must be cut flat or leveled, while other edge areas must not be scratched or cut.

4. When inspecting the appearance, pay attention to shrinkage, color mixing, top height, lack of glue, material patterns, etc. Be clear about the limit of the receiving degree.

5. For products with strict appearance requirements, such as mirrors, light buttons, smooth surfaces, etc., which are not painted but installed on the outside, there must be no handprints or oil spots. The workbench should be kept clean and free from scratches and abrasions on the products.

6. During production, a comprehensive inspection of the products should be conducted every 30 minutes. Carefully check the samples and quality inspection packaging instructions to ensure that the qualification rate of the produced products reaches 100%.

7. At the same time, pay attention to whether the nozzle of the machine is leaking rubber, whether the hopper needs to be filled with materials, whether there are problems with the mold, and whether the production tasks are completed every hour.

8. Overview of the plastic injection molding processing factory: When a box is completed, carefully check the quantity, correctly fill in the trademark paper, pay attention to whether it is pasted wrongly, and place the goods in the designated area neatly.
