Plastic Injection Molds

At Eagle Mold Co., Inc., we specialize in the design, engineering, and fabrication of precision molds used in the plastic injection molding industry. Our specialty includes the manufacturing of molds used to produce precision aerospace, medical, and automotive components, but our experience and expertise extends to a wide range of industries. The first step to creating a premium quality mold is creating a CAD model and simulating the molding process. Designs can be created based on a technical drawing of the molded component or a physical specimen that must be reverse engineered. If needed, we can also provide guidance on optimizing a specific component for the injection molded process. There may be ways to slightly modify the part which can save costs without reducing the functionality of the component. Taking this into account early on in the mold design process can greatly reduce production costs. Depending on the component design, specialty features such as hydraulic core pull, two-shot, unscrewing, and hot runner mold types can be used to accommodate unique part geometries.

Once the design has been finalized and approved, the precision mold is machined using advanced CNC milling and EDM equipment. CNC mills have 5-axis machining capabilities, allowing even the most complex designs to be milled in a single set-up. This not only increases machining efficiency, which in turn reduces overall costs and lead time, but increases the precision of the tolerances that can be held since cuts are referenced off a single point, eliminating the variability that inherently results from multiple set ups. Electrical discharge machining, or EDM, equipment provides the ability to machine components to within ±0.0001" and with surface finishes fine enough to meet the quality specifications of the most demanding manufacturing industries.

We are ISO 9001:2008 certified and perform all quality checks and inspections according to our stringent quality management system. CMM equipment is present on the shop floor to perform dimensional inspections when needed. The lead time required to produce a mold is dependent on the level of design work required and extent of the special project, but typical mold manufacturing projects can be turned around in approximately 10 to 12 weeks.
