It is an ideal solution for metal materials with low shear strength, such as aluminum die casting, to ensure high vibration resistance and torsional resistance.
■Helicoil When using bolts on a base material with low shear strength, the threads can easily be damaged. Attempting to repair it may require replacing the entire product, but by using a helicoil, you can simply replace the helicoil itself, reducing the risk of needing to replace the entire product for thread repair. This keeps costs to a minimum. ■Kobsert Used for reinforcing threads and repairing damaged threads. It can be mechanically secured firmly without the need for additional fixing pins, washers, or chemical adhesives. Kobserts with sealing rings maintain even higher airtightness. Additionally, it is possible to replace old ones with new ones. Therefore, Kobserts with sealing rings can extend the lifespan of applications and provide high cost-effectiveness. Assembly is also simple and easy. It can be installed easily by anyone without requiring specialized skills. 【Features】 - Thread reinforcement - High airtightness and corrosion resistance - Excellent seismic resistance - Wide variety - Easy installation - Replaceable
Inquire About This Product
basic information
Helicoils are increasingly being made from aluminum due to the requirements for lightweight automobiles, so the demand is growing. The target products include aluminum engines, turbochargers, and magnesium products. When assembling the Cobsert into the application, it should be installed so that the flange is flat with the workpiece. After installation, it ensures that the screw does not loosen even when the parts are subjected to dynamic screw loads or extreme temperatures. If high airtightness is required, Cobserts with sealing rings are recommended. You can choose the sealing ring based on the operating temperature (Max 300 degrees). Custom designs are also possible if you have other requests.
