Stretching machine

In the production of electrical heating elements, laminated elements can show length variations of up to 2%, which impacts the accurate distribution of dimensional tolerances. The CSM MACHINERY straightening machine is the ideal solution to compensate for these length differences, thereby optimizing the production process and ensuring maximum precision.

This machine, characterized by its simple yet robust construction, requires minimal maintenance. Its straightening action improves the linearity of the heating element, guaranteeing a superior final product quality. The CSM MACHINERY stretch-to-length machine is designed for use with heat-treated heating elements and is ideal for medium to large production batches.

  • Stretching + cleaning of terminal pins
  • Stretching + electrical tests

It is possible to add one only additional station to do in automatic an additional operation that can be added to the machine, such as cleaning of terminal pins, by means of electropneumatic units with rotating mandrel and appropriate tooling.

It is possible to add one only additional station to do in automatic an additional operation that can be added to the machine, such as electrical tests. This consists of an instrument to measure the ohmic value (mod. 232/00), an instrument to measure dielectric strength (Mod. 232/10) and a pair of pneumatically moved contacts are included.
