Plastic staking is a method of joining components together that uses a molded stud or boss to mechanically retain a mating component. Heat is applied to the boss, softening it. A forming tool is then used to reshape the material into a cap or stake.
Hot-plate welding is the process of welding two plastic parts together using a heated tooling plate. A weld rib or bead on each component is brought into contact with the hot plate. Heat conducts into the weld rib causing it to melt. The heated tool is then removed and the parts are pushed together until they bond to one another.
Vibration welding is the process of welding two plastic parts together using linear vibration. A weld rib or bead on one component is vibrated in shear against another component. Heat is generated from friction causing the weld rib to melt. Vibration is stopped and the parts are clamped together until they bond to one another.
Hybrid vibration welding adds an infrared (IR) preheat to the beginning of the cycle to soften the rib and reduce the amount of particulate flash generated from the vibration cycle.
Spin welding is a method of joining plastic components together with surface friction concentrated in a circular weld joint. One part is spun relative to another and force is applied causing the material to heat and melt. The spinning process stops and the parts continue to be pressed together while they bond together.
Innovative through-transmission infrared welding in a compact package. This technology uses focused IR light energy to replace adhesives. Useful in both linear and spot welding applications.
Ultrasonic welding uses high-frequency vibration to melt and weld plastic. A tool vibrates at ultrasonic frequencies and causes concentrated molecular vibration in the weld joint. The friction between the molecules heats and melts the plastic. Once the vibration is stopped, the tool maintains a holding pressure on the joint to create a bond.
