Mengikut kaedah membentuk, plastik boleh dibahagikan kepada plastik termoplastik dan plastik termoset. Plastik termoset, seperti serbuk bakelit, terbentuk secara kekal dengan menekan di bawah pemanasan dan tekanan. Acuan bakelit secara berkala tertakluk kepada tekanan dan dipanaskan secara berterusan pada 150-200 darjah. Termoplastik, such as polyvinyl chloride, are usually formed by injection moulding. Plastics are heated in a separate heating chamber and then injected into colder moulding chambers in a softening state to exert pressure, thus bringing about cold and hard moulding.
The manufacturing cost of plastic moulds is high, and the material cost only accounts for a small part of the cost of moulds. Oleh itu, when choosing steel, steel with good technological performance, stable performance and long service life should be preferred. Secara khusus, the following requirements are put forward for plastic moulds:
- Excellent machinability: The geometric shape of the cavity of plastic mould is very complex, and it requires processing deep holes, deep grooves and other difficult-to-machine parts. Steel must have the ability
of easy cutting. When choosing steel, if other conditions can be satisfied, it is the basis for the final selection.
- Prestasi penggilapan yang sangat baik: no matter what kind of plastic mould, the allowable surface roughness of its cavity is very small, almost all of them require mirror gloss. To achieve mirror gloss, steel must have good hardness. Pertama sekali, the impurities in steel should be as few as possible, and there should be no bubbles, and the microstructures are uniform, in large quantities. Surface roughness is also an important condition for moulds used in production.
- Good surface corrosion machinability: Many moulds require that the surface of the moulded plastic parts be patterned with various other materials, such as leather, silk, cloth, fine patterns, dan lain-lain. This requires that the quality of the steel is fine and uniform, otherwise the effect of corrosion is not good.
- Good wear resistance and toughness: Plastic moulds are subjected to thermal alternating load for a long time, and also to friction for a long time. If only one side of friction resistance is considered, and the other side of periodic alternating heat load is not considered, the high carbon high alloy steels manufactured by cold-punching moulds will inevitably have insufficient toughness and cause cracking.
- Good quenching performance and small deformation: most of the cavity parts of plastic moulds must be heat treated, which requires steel to have good hardenability and small deformation. Secara amnya, thermoplastic moulds can be processed by tempering and pre-hardening, while thermosetting plastic moulds must be hardened.
