Injection Molding

At Poly-Tek, we employ state-of-the-art plastic injection molding machines that are highly automated to ensure an efficient process. Injection molding is a typical process for the production of parts molded in large volumes, frequently used in high mass production. The associated mold costs are in comparison to other processes is relatively high. Injection molding machines are characterized according to their clamping force. Poly-Tek is capable of molding parts requiring up to 1500 tons of clamping force. Poly-Tek and its design associates have been building plastic injection molds for over 50 years. We’re capable of continuous flow molding using 50+ cavities with tolerances as small as +/- 0.002mm.


We help companies navigate plastic injection molding methods to streamline products and processes, save money and work smarter. We don’t just manufacturer the right parts, we evaluate the full process, helping companies deliver and outperform the competition.
