  • Why Use Foam Injection Molding ?

    China has started ban of the production and sale of cars using traditional fuels. At present, Nissan, BAIC, Volvo, Changan Automobile and other car companies have announced their schedule of phasing out fuel vehicles and move towards of development of new electric vehicle.  However, subjected to the mileage of electric vehicles, lightweight issue has become one of the tops ones that needs to be addressed urgently by vehicle manufacturers. Therefore, Micro-foam injection molding technology technology is more and more widely used.     What is Foam Injection Molding? Injection Foam Molding is a low-pressure process where molten resin is injected with nitrogen gas or a chemical blowing agent. The resin is then shot into the cavity, without overfilling or packing it out. The blowing agent or gas then expands to push the molten resin to the extremities of the cavities. As the part cools, the internal pressure of the foaming action takes up the internal shrinkage and reduces sinks over ribs or heavy cross-sections.  …

  • How to Select the Right Tool Steel for Your Injection Mold

    When it comes up to the process of selecting right steel for your plastic injections molds, there are a few thing need to be taken into account such as the plastic material you’ll be molding, injection molding cycle-time expectations,plastic part design requirement, expected production volume, injection molding mold costs and etc. These articles here are just to offer some guidance that we should consider when deciding the right steel for the construction of plastic molds. Most commonly used mold steels are P20、718、718H、S136、S136H、NAK80、NAK55、738、738H、S55C、H13、SKD、 DF2、8407、2311 NAK80 . There are always two sides to every coin, so it’s important to know all angels to understand the long-term manufacturing cost VS. just the up-front tooling costs. If you need a steel that is wear-resistant, you are looking at a hardened tool steel of HRC48-52. H13 or 2344 will be your ideal choices due to the fact that H-13 has a good combination of shock and abrasion resistance, and good red hardness.  This material can withstand rapid cooling and it resists premature heat checking.  As a…
