Different types of Prototype Molds Making prototype molds is as much as art as it is a science and there are a range of feasible mold types that can be utilized in order to develop prototype parts. Here are some of the few common variants for prototype molds: 1, MUD Molds MUD Molds stands for Master Unit Die molds. Sometimes, it also can refer as Mother moldbase with interchangeable inserts. It includes mold insert and moldbase, the inserts can share the same moldbase. Usually the mold manufacturer owns the mold base and will manufacture the insert by CNC, EDM and wire cut according to the design. MUD Molds can reduce your up-front injection mold investment while maintaining the production unit part cost. 2, Prototype Hand Tooling Hand tooling options simplify the mold a lot, the production of the part requires the operator to put the insert or slider into the mold by hand, then demold parts after the injection process is complete. For example, the part with inner thread, if you make it as a full automatic mold, you have to make it as a unscrewing mold, the price mold is high. If the part volume is low, you can make the thread as a insert, put the insert into the mold for molding, demold the insert by hand. Prototype mannual tooling is by far the most cost-effective means of injection molding a part. 3, Aluminum Mold Tooling Manufacturing Aluminum is easier than manufacturing steel. 4, Steel Prototype Mold If we use steel prototype mold, we can check both the part design, tooling structure and production issues. Choosing the right type of prototype mold can be complicated as there are many options available. However, if you know the material and design that you want to develop, it can help you decide which type of variant should you used. Each of the types has its pros and cons that you can take into consideration before choosing the one that suits your requirements.
