As the SUJ2 bearing steel is largely used, the guide post has superior durability and interchangeability in terms of the guiding performance. This plastic injection mold component features premium quality, high precision and beautiful metallic luster; it has outer guiding post and inner guiding post.
H-13, P-20, 420ss - Alloy Tool Steel Inc.P-20 is a very popular mold steel grade. P-20 is used for plastic injection and compression molds, and zinc die casting dies. Molds from this material can be made and placed directly into service. P-20 has a machinability rating of 65% of a 1% carbon tool steel.

How To Choose Material For Injection Molds, S7, P20, NAK S7 is probably the most common steel used in the USA for plastic injection molds, or moulds for the rest of the world. This steel is relatively easy to machine, can be hardened to Rockwell 54-59, which is certainly hard enough for a mold. It is easy to polish to a high lustre, is
How To Choose Materials For Plastic Injection Mold Tools When considering plastic injection molding for a project, product designers and engineers should consider not only what thermoforming or thermoplastic resin to use but also the choice of metal for the injection mold tool. The choice of tooling raw material influences production lead times, cycle times, finished part quality, and cost, among other things.
Jan 13, 2021 · While there is no general purpose steel for plastic plastic injection molds, P-20 steel has been regarded as the workhorse of the industry. Supplied in the pre-hardened state at Rc 30-32, it is very tough, yet fairly easily machined.
Plastic Injection Molds:Steel Vs. Aluminum RevpartJun 26, 2018 · Advantage:Steel. While both steel and aluminum are usually suitable for a broad range of standard injection molding resins, steel can offer an advantage if youre working with more complex or advanced formulations such as those reinforced with glass, fiber or other additives.
Porous Steel Improves Mold Venting Modern Machine ShopDec 15, 2001 · Editor. Permeable steel improves the quality of injection-molded parts by facilitating the escape of trapped gases. Unvented air produces a glossy surface on plastic parts (left). With proper venting, parts come out of the mold with a matte finish that is
P-20 What material are injection molds made of? Since moulds have been expensive to manufacture, they were usually only used in mass production where thousands of parts were being produced. Typical moulds are constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. What is plastic Mould steel? P-type or plastic mould steel are classified 
TOOLING:How to Select the Right Tool Steel for Mold Aug 25, 2016 · For molding materials that do not contain abrasives like glass fibers or corrosive ingredients, P-20 steel is the most common choice. But with smaller tools for high-volume production, hardened tool steels are always a good option to prolong the tool life with reduced maintenance.
Your Ultimate Guide to Plastic Injection MoldingFrom there, the process will just repeat itself where the clamps have to push the two halves of the mold close together. Plastic injection molding is best in producing plastic parts that have to be mass-produced, like car parts, medical instruments, bottle caps, mobile cases, etc. Things to Consider with Plastic Injection Molding
Dec 04, 2018 · Plastic Injection Molding Materials Al-7075. Aluminum 7075 is a high-strength aluminum alloy with a relatively large percentage of zinc. Pros. Aluminum has the best heat transfer properties of common tool metals. Why is this important? It means the tool can be heated and cooled quickly and efficiently. This has two advantages.
