When the pressure of injection mold cavity is insufficient, the extrusion pressure of melt on the surface of mold cavity is low, which is especially obvious on the surface of the workpiece far from the gate. In the middle part of the process, the cavity pressure is higher, the surface replication degree is better, so the luster is less. The area closest to the gate has the highest pressure and the best reproduction, so the surface of the product is matte. Avoid the use of large pressure loss of the latent gate and point gate, and use a large gate thickness and width. On the premise of not affecting the appearance, the number of sprue should be increased appropriately, the length ratio of melt filling mold should be reduced, and the pressure of mold cavity at the end of flow should be improved. Sandblasting on the surface of the mold can eliminate some sharp corners, which is beneficial to the copy of the leather grain and reduce the possibility of bad copy on the surface.
Injection molded plastic parts (Making plastic parts) are designed as rectangles for the panel operation of the oven. The four corners have protruding columns for easy insertion into the assembly accessories. The horizontal bar in the middle can distinguish the functional operation. Plastic panel is easy to install and operate.
