TPR ABS Over molding, plastic injection molding parts

Surface modification and marking

Surface modification of plastic parts. The surface quality of plastic parts can be evaluated by the roughness of the surface of GB/T 14234-93 plastic parts. However, the surface quality of plastic parts is related to the gloss and transparency of plastic materials. The surface roughness of plastic parts is very poor. The low surface hardness and the instability of body size make it difficult to measure and evaluate the surface roughness of plastic parts.

The surface roughness of injection moulded parts is generally worse than that of the cavity surface, and it is related to the injection process. In recent years, plastic parts with decorative patterns have been widely used. Surface modification can improve the appearance quality and added value of plastic parts.

Convex and concave lines and markings on plastic parts. In order to facilitate control or decoration, knobs, handles and bottle caps and other plastic products often have some convex or concave lines. When designing the punch and concave, the direction of the punch and concave should be the same as the direction of demoulding. The direction of the punch and concave makes demoulding more difficult. After changing the structure of the punch and concave, the demoulding can be carried out smoothly. When designing convex and concave lines, attention should also be paid to the distance between the lines should be as large as possible to reduce the difficulty of die manufacturing.

Marks, words and symbols on the surface of plastic parts can also be moulded. There are three types of markings on the surface of plastic parts. It is difficult to process concave marks on the surface into convex marks on the forming die. The marking of convex shape on the surface of plastic parts is processed into concave shape on the tool, which is more convenient. But convex plastic markings are easy to damage. Under the surface of the plastic part, mark it with a convex shape. The marked part is assembled with insert parts. This is the most common way to set tags. Note that the convex mark in the pit is about 0.2 mm lower than the surface of the plastic part.

In order to ensure the strength of the plastic marking itself, the width of the marking should not be less than 0.3 mm. The interval between markers should be greater than 0.4 mm. The depth or height of the marker is 0.2-0.5 mm, and should not exceed 0.8 mm. The mark itself has a demoulding slope of more than 80.

In addition to setting reinforcing bars, the strength and stiffness of products can be improved, and the reinforcing structure can also be set on the products. The bottom of the container is designed as the curved surface of the outer arch, the curved surface of the inner arch and the convex platform, so as to improve the strength and stiffness of the product and increase the beauty. Prevent warping by thickening the edges of the container.
