What should be noted during plastic injection molding operation?

1、 Adjustment of production process:

①Check whether the process parameters are the same as the actual model, material, and mold;

②When inputting process parameters simultaneously, start producing the first can of beer at a slightly reduced pressure rate, and then gradually adjust (based on product quality ratio);

When there are no process parameters, it is important to know the mold structure, adhesive dosage, and other adjustments. Blind adjustments are strictly prohibited. Note that if the dedicated mold is not glued enough, it will stick to the mold, and if there are too many adhesive lines, it will stick.

2、 Operator production:

①Check if the machine's safety adjustment is safe;

②Are the operators familiar with the product quality standards before operation;

③ The plastic injection molding factory states that the processing method must be correct, such as: the nozzle position must be cut flat or approved flat, and other edges must not be damaged or cut flat;

④ Check the appearance and pay attention to shrinkage, color mixing, top height, missing glue, flowers, etc. And clarify the uncertainty of the maximum acceptance;

⑤Products with strict appearance requirements, such as mirrors, light knobs, smooth surfaces, etc. It has not been sprayed with oil and assembled outside, so there must be no fingerprints or oil stains. The workbench should be kept clean and the products should not have scratches or abrasions.

⑥During the production process, a comprehensive inspection of the product is conducted every 30 minutes, carefully checking the samples and quality inspection packaging instructions to ensure that the product qualification rate reaches 100%;

⑦At the same time, pay attention to whether the nozzle of the machine leaks glue, whether the hopper needs to be loaded, whether there are any problems with the mold, and whether the production task is completed every hour;

⑧ Carefully check the quantity, fill in the trademark paper correctly, pay attention to whether it is pasted incorrectly, and place the goods in the designated area in order.
