The "Impulse Welder" is an energy-saving type of spot welding machine that allows for safe thermal fusion with excellent quality stability, thanks to our unique instant heating and cooling method. It can adjust heating and cooling times, resulting in uniform and beautiful welding surfaces without burning or stringing. Additionally, due to the low residual stress, it enables welding that is less prone to wear over time. Preheating is unnecessary due to instant electrification, which also reduces power consumption waste. Moreover, since it uses a joining method that does not involve metal parts, it contributes to a reduction in the number of components, lightweight products, and improved recyclability. 【Features】 - Compatible with welding thermoplastic resins such as ABS, PMMA, PP, PE, PBT, and PPS. - Various finishing shapes can be accommodated by exchanging welding chips. - Three types of control methods are available. - No noise, vibration, or odor is generated during operation, allowing for comfortable work (cooling air noise will occur). *For more details, please refer to the catalog available for download in PDF format. You can also check examples of use for joining the same materials, joining different materials (by riveting), hole sealing, and outer circumference riveting.
