Poor surface texture of injection molded products refers to the fact that the texture on the surface is not in accordance with the requirements in terms of thickness, depth, density, gloss, etc. Problems such as scratches on the texture, incomplete texture application in certain areas, and corrosion in non-textured areas are major challenges for mold manufacturers. Since poor surface texture of injection molded products seriously affects the appearance of the products, and corrosion further reduces the strength and quality of the products, no one is willing to purchase products that are not up to standard. Therefore, mold manufacturers must solve the problem of poor surface texture of products. So, what are the causes of poor surface texture of products?

1.The surface of the pre-molding die has poor polishing, which prevents the mold cavity surface from being accurately replicated during the product molding process. As a result, uneven glossiness will appear on the product surface. 

2. The skin patterns are too fine and do not connect with each other. This makes it very likely for air to get trapped within the patterns, thereby causing various defects in the product. 

3. The materials of the steel parts are different, uneven, and have laser welding, which is brought to the surface of the product during the processing. 

4. The filling speed of the plastic mold is too slow, resulting in insufficient pressure in the mold cavity to replicate the mold surface. 

5. The viscosity of the plastic raw materials is too high, resulting in poor fluidity. As a result, the surface of the product will exhibit undesirable surface patterns such as skin lines, air lines, and injection lines. 

6. The mold temperature and the melt temperature are too low, and the size of the gate and the flow channel is too small. Under such production conditions, the products are prone to various defects.
