There are three types of Bollhoff IMTEC® inserts available: IMTEC® CO (Coiled), IMTEC® CF (Cold Forming), and IMTEC® HR (High Mechanical Resistance). All three types offer strong, long-lasting metal threads inside plastic parts. Before the part is made, the inserts are placed into the mold by hand or with a machine. Then, plastic is injected around them, securing the metal pieces inside the application. Each type offers specific benefits: coiled for flexibility, cold forming for efficient production, and high mechanical resistance for demanding applications. This variety means you can select the insert that best matches your performance needs. You can contact one of our fastener experts to find the IMTEC® threaded insert for plastic that best fits your needs!
