China Plastic Injection Molding operator processing requirements
1, Quality operational requirements for plastic products
1, The injection molding forming of the product, must ensure that the product structure is complete. There is no less material, more material phenomena.
2, Plastic product surface bright, uniform chromaticity, full.
3, Plastic product surface is not filled with flowers, impurities, defects such as black spots.
4, The product shape is neat, there is no deformation, distortion. And the internal products are obvious bubble phenomena.
5, The product can cooperate with relevant parts is normal. Without external force can not be separated.
6, The assembled product to need, after assembling the operator’s need to introspection. To ensure that
products meet quality requirements. There is no installed in place, packing, and has a fracture phenomenon.
2, The Plastics quality management in products trimming
1, The plastic molding product of the inlet with trimming knife cutting. Cutting mouth who can not have express
white appearance.
2, When trimming knife trimming, forcibly when repairing products shall repair products outside introversion.
The resistance force direction is not allowed to have another hand block.
3, Product trim on the handle of the strength should be uniform. Can guarantee hard cut products as much as possible, long group of the front, middle not stagnation. A fix to the end, to ensure that after trimming the edges of the beautiful appearance.
4, The surface of the injection molding product by trimming does not allow defects wavy lines, and uneven in china companies.
5, To remove the inlet area, trimming should level off, allow the phi 10 from minor scratches, trimming to improper. Other parts that are not allowed to have should be trimming undeserved cause scratch defects.
6, To put front height is greater than 0.2 mm should be handled for trimming (unless adjusting injection parameters to solve). Especially in the production Product outline on the edge of the phi front must be removed.
7, For different products, it is suggested that we should use different types of trimming knives (if mold making is nice,
Not need it). To ensure product quality, improve the efficiency of trimming.
8, Don’t allow should trim other qualified on the surface of the damage caused by improper operation. Such as good surface scratches, cut, etc.
3, China injection molding company product storage and handling
The product stacked on the pallet height should not exceed 1.2 mm. The number of the same specifications for each building product must be the same, with winding mode finally. For small products in the turnover box, the bottom in the turnover box height should be 10 cm. The turnover box has a loading weight of not more than 25 kg.
