MOLDMAKER VS. MOLDER The question is always put forward to me, "why go to a Moldmaker? I really don't want a mold, I want plastic parts." On the surface it may make sense to go to a molder for plastic parts. But if you care to look deeper, a good plastic part starts with a good plastic part design and a good mold. When you choose a molder, you are generally talking to someone with limited mold expertise. Often, a molder spends very little time evaluating the plastic part design, leaving that to the Moldmaker. Instead, a molder is more concerned with part weight and cavitation as it affects mold press size. Even if they have "in house" tooling capability, quite frequently a molder contracts out for the new mold. Very little evaluation goes into the part design as it affects the mold. When you choose a MOLDMAKER you get immediate feedback on you part design (a reality check if you will). A Moldmaker looks at a part from all directions relating more to the construction and stability of the part and the practicality of the manufacturing process to repeatedly make that part. The goal is to have a mature part design that leads to a highly manufacturable part with the widest possible process window. A Moldmaker will consider the part design as it affects the following:
