Preparation for injection moulding
The plastic inside the mould is gradually and evenly coated, melted and adhered to the entire surface of the mould cavity under the action of gravity and heat, and shaped into the required shape, and cooled and shaped. The injection process generally consists of: adding material - plasticizing - injection - cooling - demoulding, so what to do before the injection mould processing molding preparation matters
The reasonable choice of materials and the requirements of the prescribed heat treatment for drop-forged parts are important to increase the strength and service life of shaft components and, at the same time, have a large impact on the processing of shafts. Shaft components are generally made of 45 steel, with different heat treatment specifications (e.g. normalised, tempered, quenched, etc.) to obtain strength, toughness and resistance to wear, depending on the working conditions.
