La plus grande différence entreattaches standards and non-attaches standards is whether there is standardization. The structure, size, drawing method, marking and other aspects of attaches standards have strict specifications set by the country. (Parts), common attaches standards include threaded parts, keys, pins, rolling bearings and so on.
Non-attaches standards are different for each mold. The parts on the mold that are in contact with the glue position of the product are generally non-standard parts. The main ones are the front mold, the rear mold, and the insert. It can also be said that except for screws, faucets, thimbles, rubber rings, springs, and mold blanks, almost all the rest are non-attaches standards. If you want to purchase non-attaches standards, the purchaser should generally provide design inputs such as technical specifications, draft drawings, etc., and the supplier will evaluate the difficulty of realization of non-attaches standards based on this, and initially estimate the production of non-attaches standards Cost, batch size, production cycle, etc.
