What does that mean when the composite material is pressed and molded? What are pressing forming? What are the characteristics of press molding equipment? Its development
Can be used to shape complex products. The principle is similar to that of injection molding. One is used for thermosetting, heating and cooling in molds, one for thermoplastic, and the other for heating in the barrel and molding cooling in the mold.
Molding: mainly used for thermosetting resins. There is a special molding machine. Molding pressure is much greater than the above. The mold structure is also more complex.
Different conceptsCompression molding refers to hot forming: mainly for thermoplastic materials (sheet), the use of hot forming machine, Blister molding, I think it should also be considered as a branch of hot stamping, vacuum or high-pressure gas will be used to assist. Hot pressing sheet forming a relatively small depth, relatively simple structure, low precision products, such as packaging materials, plastic pallets, plates in the dishes and so on. There are also forming plate pressing molding (lamination)
