This picture shows a very typical long oblique core pulling structure in mold. This is a technology widely used especially in Automotive products. This requires tight tolerance during machining each components, and also requires for good bench work skill during fitting and assembly. Tiny deviation can cause failure. With our top advanced machining machines like Makino, GF AgieCharmilles, Sodick, for those special inserts tolerance as tight as 0.002mm can be reached; our bench workers are all highly proficient and skillful guys with more than 10years experience in this industry. These has greatly enable us to undertake most complex projects successfully! In some cases of long oblique core pulling tools, we need to use 3D printing inserts to make sure 100% accuracy so that all fits each other exactly like what designed in 3D drawing. To make sure long-term safety for mass production, DLC coating is highly recommended. With cooperation to our Israeli partners, we have been keeping improving our technology and knowledge to different kind of tools by using the most updated technology to get projects done neatly and efficiently. This is our key of keeping our customers satisfied. Therefore how does the mold is affect the smooth and efficient injection molding production? It is mainly reflected in the following aspects: Product quality: At least 70% of the product quality is determined by the mold, and the impact on high-precision plastic injection products is more prominent. 1) Only when the precision and quality of the mold meet the requirements, can it meet the prerequisites for smoothly and efficiently producing products that meet the precision and surface requirements. 2) For the appearance of the product, the texture surface mainly depends on the texture quality of the mold, and the smooth surface and mirror surface mainly depend on the polishing quality of the mold cavity surface.  3) For the non-appearance surface of the product, the surface quality of the mold can directly reflect the roughness of the product surface. 4) For product size (except for product shrinkage and injection molding process), the most direct impact is the dimensional accuracy of the mold. The higher the dimensional accuracy of the mold, the higher the dimensional accuracy of the product.
