Plastic mold steels are used in the manufacturing of plastic molds, depending on the type of plastic raw materials used and their resistance to various factors such as wear, pressure, and corrosion. These steels are developed to suit the characteristics of different plastic materials. There are various types of plastic mold steels widely used, such as 1.1730, 1.2312, 1.2738, 1.2311, 1.2344, 1.2379, 1.2767, 1.2842, 1.2083, 1.2316, 1.4112, 1.8519, and 1.8550.
It is hardened steel that can achieve a mirror-like shine with a hardness of 280 - 325 HB.
1.2767 (VNC4) (45NiCrMo16)
1.2379 (CPPU) (X153CrMoV12)
It can be used in molds of plastics such as bakelite, which has an abrasive effect. Due to its 4% nickel content, its hardenability is very high. Its brightness ability is good.
Used for mandrels and screws hardened to the core. Plastics containing feeders cause significant abrasive wear.
Hardened to 280-325 HB, it gives very good results in the screw, barrel making, and plastic molds.
1.2316 (R65) (X38CrMo16)
1.2083 (HC50) (X40Cr14)
It is a steel that can be used in molds of plastics such as PVC, which have a corrosive effect, without the need for hardening. 1.2083, which can be hardened as a core (50-54 HRC) in molds that must be completely stainless, and 1.2316 as a holder form a good pair.
It has the best combination of toughness, abrasive wear and corrosion resistance. Due to their high toughness, these materials are used as screws and nozzles in plastics containing abrasive additives such as glass fiber or metallic oxide.
Problems such as core movement, burr formation, and bearer crushing, which are usually experienced in materials with low mechanical properties such as platinum or iron, can be overcome with this steel.
