Equipment to Produce Precision Injection Molded Components


Some end-users prefer to utilize different vendors for each step of the injection molding process. Once an engineer at one firm has completed the design and the mold has been cast at another, the difficult task of finding the proper equipment to produce precision injected molded components begins. Other end-users feel, however, that quality control is better served and that it is generally more economical to have a single company provide the entire array of injection molding services under one roof.

Regardless of the approach one take, various types of industrial strength machines are needed to produce custom molded components, most notably, machining tools and injection molding presses.

Machining Tools

Mold production is performed by one of two devices, a Computer Numerical Control (CNC) system or an Electrical Discharging Machine (EDM).

Modern CNC systems integrate computer aided design (CAD) and computer aided manufacturing (CAM) programs. A component design is developed in the CAD program and then fed to the CAM program which ultimately controls the production of the mold.

EDMs utilize a completely different method of producing a mold. Instead of metal on metal tooling, like CNC, EDMs remove unwanted material through the use of high energy electrical discharges. The smaller, more versatile electrodes in EDMs allow for greater flexibility in producing complex components.

With both these systems, the real difficulties in custom plastic injection molding lay in the design process. Not only must the actual component be designed but an appropriate production process must also be crafted. Once these two items are finalized, the actual production is computer controlled.

Injection Molders

Injection molders come in a variety of shapes and sizes. All have one feature in common, though; they inject a substrate into a mold under extremely high pressures. The similarities end here as there are literally dozens of specialty models that can produce molded parts in a panoply of sizes, shapes and materials.

Some molders use different substrates. Others enlist the aid of water or vibration in the molding process. Still others operate at the microcellular level. Experts are required to efficiently utilize each of these machines.
