injection molded parts
injection mold tooling
The method of injection molding involves heating plastic to high temperatures sometimes in excess of 600 degrees and forcing the liquid plastic, under extreme pressure and clamping force into a steel mold. The mold is then rapidly chilled and the part is ejected. This happens all with- in seconds. Injection molding is the ultimate method for part manufacturing and high volume production.
- parts with complex geometry and high levels of detail are easily achieved - cycle times are fast making parts cost effective - multiple parts can be made in one mold meeting production demands - close tolerances are easily met, sometimes under .001
Advantages with injection molding
Some of our capabilities include: - process a wide range of materials including engineering grades - overmolding and hand loading threaded inserts - 75 - 700 ton injection molding machines - 2 grams to 64 ounce in part weight - part design and CAD drawing services - U.S. and offshore mold manufacturing - full fabrication and CNC machine services - 24 hr / 6 day production capabilities
Depending on your requirements, literally thousands of materials can be injection molded. These range from polypropylene used in toys, to ABS used in consumer electronics, to nylon used for engineering grade applications, to silicone used for high heat requirements.

Plastic injection molded parts can be:
- reinforced with glass or graphite, exhibits metal characteristics - resistant to extreme hot or cold temperatures -40 to 500F - resistant to caustic chemicals and ultra violet light exposure - low CLTE (co-efficient of linear expansion) good for outdoor applications - exhibit rubber like characteristics when using thermoplastic elastomers - anti-stat inhibitors for electronic requirements - chrome plated for automotive applications For a definition of some common plastic terms seeplastic terms
