射出模具製造

The injection molding process can be roughly divided into the following six stages: Mold closing, glue injection, pressure holding, cooling, mold opening, and product removal. The above process is carried out repeatedly, and the products can be produced periodically in batches. The molding of thermoset plastics and rubber also involves the same process. 然而, the temperature of the barrel is hotter, the temperature of the plastic is lower, and the injection pressure is higher. The mold is heated, and the material needs to be cured or vulcanized in the mold after injection, and then released while it is hot. The trend of today's processing technology is developing in the direction of high technology.
