Transfer molding is also called transfer molding.
Transfer molding is a molding method for thermosetting plastics. During molding, the molding material is first heated and softened in a heating chamber, and then pressed into the heated mold cavity for curing and molding.
Transfer molding has different types of work depending on the equipment: в┘ movable plate type; в┌ tank type; в█ plunger type.
Transfer molding requires plastics to have greater fluidity before reaching the curing temperature, and to have a faster curing rate after reaching the curing temperature. Phenolic, melamine formaldehyde and epoxy resins can meet this requirement.
Transfer molding has the following advantages: в┘ There is less waste on the product, which can reduce the amount of post-processing; в┌ It can mold products with delicate or fragile inserts and perforations, and can keep the correct position of the inserts and holes; в█ The product has uniform performance, accurate size and high quality; в▄ The mold wear is small. Disadvantages are: в▌ The manufacturing cost of the mold is higher than that of the compression mold; в▐ The plastic loss is large; в▀ Fiber-reinforced plastics produce anisotropy due to fiber orientation; вр The plastic surrounding the insert sometimes reduces the strength of the product due to poor melting.
