Hot Crimping Systems

As the (typical large) products that are made by Hot Crimping typical have a very high intrinsic value, and even higher service/repair costs, you can only afford to use the best possible production equipment for this.

A high-force weld head (for example MIYACHI PECO M200/7500N) mechanically holds the electrodes. It also feeds the electrical current to the electrodes. Cooling water is applied to cool all components actively to prevent (over-) heating during production. The transformer (MIYACHI PECO TR5/P) is mounted directly on top of the weldhead. The power supply that generates the electrical current for the welding is typically an AC-current MIYACHI PECO power supply, for example type M4P.

Unique for our Hot Crimping equipment is the "weld to displacement"functionality. This allows the equipment to be programmed to reach a certain compression (defined in micron or milimeters), upon which the current flow and heating will be switched off. This compensates for part-to-part variation, and lets you program a parameter that is closely related to joint quality.

A good quality MIYACHI PECO power supply and transformer will accurately emit the electrical power that is programmed. All electrical parameters can be guarded and stored by a MIYACHI PECO MG3. This MG3 is the ultimate in process control for resistance welding and unique for the AMADA MIYACHI EUROPE product offering.

To measure and control the displacement, a linear sensor is integrated in the weldhead and connected to the power supply and the MG3. Displacement is measured and controlled. Another feature is an automatic reset for this displacement, used to compensate for electrode wear and product thickness variations.

AMADA MIYACHI EUROPE offers its expertise to all of its customers to correctly match any Hot Crimping application with the right process and equipment. Typical applications can be found in Automotive (Hybrid & Electric vehicles) as well as in electrical motor and large scale electrical generator production industries.
