Injection Table Mould is a part that gives plastic shape and size during moulding. Although the structure of the table mould may vary greatly due to the variety and performance of plastic, the shape and structure of plastic products and the types of injection machines, the basic structure is the same.

Injection table mould is divided into thermosetting plastic moulds and thermoplastic plastic moulds according to moulding characteristics. According to the moulding process, the mold can be divided into transfer mold, blow mold, casting mould, thermoforming mould, hot pressing mould (compression mould), injection mould, etc. The hot pressing mould can be divided into overflow mould, semi-overflow mould and non-overflow mould in overflow mode, and the injection mould can be divided into cold runner mould and hot runner mould in the gating system. According to the way of loading and unloading can be divided into mobile, fixed two kinds. Table mould is also classified according to different processing techniques. The injection mould injects molten plastic into the cavity of the table mould at a certain speed and pressure. After the plastic is cooled, the mold is opened to take out the molded injection product.

The compression moulding table mould is simply called a compression mould, which directly adds plastic raw materials into an open mould cavity, closes the mold, the plastic becomes a flowing state and fills the mould cavity under the action of heating and pressure, and then hardens and shapes the product through chemical crosslinking or physical cooling.

The compression moulding table mould uses a heated mold to heat and press the plastic sheet into shape, then opens the mold, takes out the moulded product, and puts it into cold water for shaping and cooling. Compression moulding is an important technical process in moulding and processing. It is widely used in industrial production and processing and plays an important role in people's lives. Generally, powder, granule, pellet, sheet or even a blank with a shape similar to that of the product is put into the cavity of a heated table mould, then the mold is closed and pressurized to form and solidify or vulcanize the product, and then the product is obtained by demoulding. This method is especially suitable for forming thermosetting plastics (see thermosetting resin). Disadvantages are long production cycle, low efficiency and poor dimensional accuracy of products.
