Custom plastic mold design and construction requires experts. Pittsfield Plastics’ complete tool room, staffed by highly trained tool makers, manufactures a mold developed thru the process of integrated Product Design.
Rapid prototyping and computer-aided mold design:
There are several steps in the design of the mold.
Economic analysis:
We will develop an economic analysis that will show you the options to get the most cost effective part from a mold designed to meet your custom plastic molding engineering standards.
Tool design:
Our tooling engineers design the tool, defining the critical aspects such as mechanical action, ejection, manifold design, and runner system.
Development of specifications:
We agree on a specification sheet. That sheet is used as basis to compare sources.
Multi source tooling options:
We can source your custom mold tool in our own shop in Pittsfield, MA for an American-made product. Or we can source your tool in the Far East or Eastern Europe.
Selection of the successful vendor:
We conduct an interactive process of selection of the vendor. After a joint decision is made, we award the purchase order and begin the process of monitoring the progress of the mold. If needed, we schedule visits to the vendor to monitor construction.
Acceptance of the tool:
Final acceptance is done at the vendor’s shop. Once the tool is accepted, it is crated and shipped to our Pittsfield, MA production facility.
Maintenance of the tool:
Pittsfield Plastics Engineering maintains all tools for its customers. It assures tools will be securely stored and production-ready.
