Compression moulds are moulded by using plastic in the closed mould cavity by means of pressurized heating. Generally, compression moulds are suitable for thermosetting plastics, such as phenolic plastics, amino plastics, unsaturated polyester plastics, etc.
Compression mould consists of three transitions: pre-pressing, pre-heating and moulding:
The main equipment for compression mould is presses and moulds. The most used presses are self-contained hydraulic presses, with tonnages ranging from tens of tons to thousands of tons. There are lower pressure presses and upper pressure presses. The moulds used for compression moulding are called pressing moulds and are divided into three categories: overflow moulds, semi-overflow moulds and non-overflow moulds.
The main advantage of the compression mould is that it can mould large flat products and can be mass-produced, but its disadvantage is that the production cycle is long. MDC Mould uses ultra-precision processing technology to create a compression mould that minimizes damage to the mould cavity during moulding and waste of composite materials, and can produce high-precision and high-quality products.
