Technology of plastic injection process

For plastic products, the degree of groovedness of the color of oil injection processing is generally selected above 10, do not choose low gloss matte, because its surface hardness will be relatively low, below 1H, and at the same time, the oil injection processing is not wear-resistant. Generally, the hardness of the paint after drying is above 2H, but when the hardness is too high, the paint will be brittle, so the general surface hardness should not exceed 4H. In order to achieve the surface hardness requirements of oil injection processing, the dual combination cross-linked type is generally selected The edge line of the paint at the same time injection processing is difficult to be straight, and often has saw defects caused by flying oil.

The plastic injection process of plastic products is a surface processing method that heats the thermal injection material to a molten or semi-fused state through a heat source, atomizes and sprays it onto the surface of the workpiece through a high-pressure air stream, and forms a special coating on the surface of the workpiece. Thermal injection. With the large number of “overlapping continuous deposition” of plastic particles, the bonding between particles should be mostly mechanical, and there must be a certain number of holes. At the same time, thermal spraying is performed in the air, and particles in the molten state will oxidize, so oxide inclusions should be present in the coating.

Nowadays, plastic products are ubiquitous, but people in today’s life do not have the functional requirements of plastic products as long as they are easy to use. Now the appearance must not only be beautiful, but also economical. In terms of cost performance, the injection surface treatment of plastic products plays a vital role in product marketing.
