Precision Injection Molding

The small parts are just as important! Throughout more than 30 years in business, Tri-Tech Tool & Design located in South Bound Brook, NJ, has truly mastered precision injection molding from solving design deficiencies to working with resins from the simplest polyethylene to high heat, performance-engineered materials. No matter what your plastic injection molding needs or challenges, we can help you meet them.

Efficient Operations
To meet the demands from a wide-range of industries, Tech Tool & Design operates two molding houses with a wealth of mold presses ranging from 30 to 200 tons of clamp force. Our primary plant houses 17 high-quality presses supplemented with a secondary plant featuring an additional 5 complete ‘lights out’ molding lines monitored largely through the Internet. Here, a support shift takes care of the basic part-time responsibilities of product inspection and packaging of daily production.

Top-Quality Injection Molding Equipment
Keep part costs at their lowest while maintaining long-term performance. Let us make your precision plastic parts with the most efficient equipment available. 13 of our 23 molding presses are all electric models, the most precise in the industry. All our machines are equipped with dryers to handle the most demanding molding applications.

Gauges and Fixtures
Your precision injection parts will not only undergo typical measurement and visual inspections – we will also design gauges and test fixtures to assure that we meet all your precision injection molding needs.

Fixed Prices that can last years!
Our specialty is small precision parts. Long-term commitments and higher volumes of small precision parts can mean significant savings for our customers. Some Tri-Tech customers have seen little or no increase in their per-part cost since they started working with us.
