There are internal and external differences for automobile covers, and correspondingly, there are also internal and external cover molds. The surface quality of the inner cover is mainly due to springback and distortion. The stability and reliability of the mold is mainly to prevent strain and improve the warpage and deformation of the part; the surface quality of the outer cover is mainly scratches, holes and edge burrs, For problems such as partial depression, forming quality of the bonding surface, and gap after assembly of the assembly, the mold requires that the working part be well-made, the assembly is precise, and the mold movement is smooth.
It should be said that China has fully possessed the ability and technology to manufacture a complete mid-size car body mold, but the mold is not mass-produced. No matter which mold factory makes any set of molds, it is ultimately the specific personnel who undertake its design and manufacturing tasks. Finish. We can do a lot in terms of overall experience accumulation and standardization, but because it’s a one-piece production, it’s really up to the individual level. At present, the inner panel molds of china OEMs are mainly produced in China, while some key outer panel molds are outsourced. Outsourcing is based on richer experience abroad, and the contracting party has greater expectations in terms of product manufacturing cycle and quality. In fact, there are many problems with outsourced molds, but for the contracting party, psychologically, they will think that there are more china problems. All in all, automobile panels have large dimensions, and are produced in line with in-line molds; small and medium-sized automobile stamping parts are more commonly used abroad with multi-station progressive molds, which are highly efficient. With the continuous development of the china auto industry, China’s auto mold industry is also making continuous progress, and the competitive advantage of foreign auto mold factories will be gradually weakened, and everyone will eventually recognize china molds more and more.
