dies materials include 45# steel, 6061 aluminum plate, alloy cast iron.
Common steel materials for injection dies include P20 steel, 718 steel, etc. Injection molding materials such as AS styrene-acrylonitrile copolymer, polycarbonate, etc. Of course, the metal materials commonly used in dies include many types, each of which has its specific application scenarios and performance characteristics. The following are several commonly used molddies metal materials and their applications:

45# steel:
This is a high-quality carbon structural steel, commonly used for medium-carbon quenched and tempered steel. It has excellent comprehensive mechanical properties, but low hardenability and is prone to cracking during water quenching. Small parts are suitable for quenching and tempering, while large parts are suitable for normalizing. 45# steel is often used to manufacture high-strength moving parts, such as turbine impellers, compressor pistons, shafts, gears, etc.
Q235A (A3 steel):
This is a widely used carbon structural steel with high plasticity, toughness and welding performance, as well as certain strength and cold bending performance. Q235A is often used to manufacture various general parts and welding structures, such as tie rods, connecting rods, pins, shafts, screws, nuts, etc.
40Cr:
This is a widely used alloy structural steel, which has good comprehensive mechanical properties, low-temperature impact toughness and hardenability after quenching and tempering. 40Cr is suitable for manufacturing medium-speed and medium-load parts, such as machine tool gears, shafts, worms, etc. After high-frequency surface quenching treatment, it can be used to manufacture parts with high surface hardness and wear resistance.
HT150:
This is a gray cast iron, which is often used to manufacture large parts such as gear boxes and machine tool beds. HT150 has good wear resistance and strength.
35 steel:
It is suitable for manufacturing various standard parts and fasteners, such as bolts, nuts, etc. 35 steel has appropriate strength and good plasticity.
65Mn:
This is a commonly used spring steel, suitable for manufacturing various small-sized flat and round springs, such as seat springs, spring springs, etc. 65Mn can also be used to make brake springs, cold-rolled spiral springs, etc.
0Cr18Ni9: This is a commonly used stainless steel. Due to its excellent corrosion resistance and beautiful appearance, it is widely used in food equipment, general chemical equipment and other fields.
Cr12:
This is a high-carbon and high-chromium type of Ledeburite steel with good hardenability and wear resistance. It is often used to manufacture cold stamping dies and punches with small impact loads.
DC53:
This is a high-strength and toughness cold working die steel. After high-temperature tempering, it has high hardness and high toughness. It is suitable for manufacturing precision cold stamping dies, drawing dies, etc.
The selection of these materials depends on the specific purpose and required performance of the die. For example, cold working die steel is mainly used to manufacture dies for pressing and forming workpieces in a cold state, such as cold punching dies, cold extrusion dies, etc.; hot working die steel is used for processing workpieces in a high temperature state, such as hot forging dies, die casting dies, etc. Of course, if you need to custom dies and produce a batch of products, you can choose to cooperate with Mulan Group. Mulan Group supports the customization of various stamping and injection dies, and the processing of various products. If you choose to process the products yourself, you can also take back the dies. Our cooperation method is flexible.
