Prototype mold is also called the injection mold. The tool life of prototype mold is shorter than mass production mold, which means the molds will be reduced in some machining process. For example, more than one cavity can share with a universal mold base. Also, we will choose different grades of steel material according to the quantity of your products, quality and surface finishing requirement. This is the best way for shortening processing time and saving the cost of the tool. Reaction injection molding and Rapid tooling services injection molding have almost the same name, so even experienced engineers and designers might think they are the same process. But “Reaction” signals a big difference – unlike injection molding, RIM techniques utilize low-viscosity liquid polymers in thermoset – not thermoplastic – processes. Raw materials and molding techniques can be selected and even customized to precisely deliver desired weight, strength, density and hardness characteristics. The result is large polyurethane parts with much lighter weight than those created by more commonplace processes.
