What materials are used for King Rubber's custom injection moulders?

We have a professional team that selects materials based on specific requirements such as the mold's specific usage, cost, and lifespan.  For some injection molding molds with high requirements for surface quality and complex shapes, like those for exquisite components of automotive interiors, P20 steel might be chosen as this type of steel has good polishing and processing properties.  If the mold needs to work in a corrosive environment, such as molds for some parts in the automotive engine compartment, 420 steel (martensitic stainless steel) would be an option because of its better corrosion resistance.
For molds exposed to high temperatures and high pressures, for example, injection molds for large automotive bumpers, H - 13 steel is more suitable as its toughness, thermal fatigue performance, and wear resistance can exert advantages in such circumstances.  A - 2 steel is suitable for small molds with extremely high precision requirements, like injection molds for automotive electronic components, as it can ensure the mold's precision remains after long-term use.  And D - 2 steel is used for molds with extremely high wear resistance requirements, such as molds for automotive interior parts with special textured surfaces.
Apart from steel, aluminum materials might also be considered.  Aluminum molds are lightweight, easy to handle and install, and have good thermal conductivity, enabling rapid cooling of the injection-molded parts.  The processing cost is relatively low, making it suitable for small-scale and short-cycle injection molding projects.  However, in cases of large-scale, complex, and high-pressure injection molding, steel molds are often a better choice due to their high hardness, high strength, and long-term stability.  In conclusion, the team weighs various factors to provide customers with the best and most economical injection molding mold solutions that meet strict industry standards.  King Rubber has many years of experience in producing high-quality injection molds for various industries and is always ready to cooperate with you to create custom injection molds that meet your needs.  Please contact us at sales@king-rubber.com to learn how we can assist you from part conception and design to engineering, injection mold manufacturing, and the manufacturing of custom parts.
