Tension springs join two components and bring them together when they try to detach. High-tension springs absorb and store energy, and when tension is applied, create a resistance to counter the pulling force.
Chemical etching has the perfect manufacturing capabilities for producing springs, flexures or diaphragms as it produces flat and stress free components. Stamping on the other hand will deform the springs causing flatness issues and laser cutting creates rough edges that could cause fatigue fracture.
We are a leading manufacturer of these type of products producing multiple million components just for the automotive industry every month including ABS braking, fuel injection, catalytic converters, etc. We’ve overcome the shift in automotive requirements by implementing CMM support “in process” offering CPK controls for CTQ features. This ensures that the requirements of tighter tolerance and repeatability are achieved.
