Many European machine manufacturers in the automotive and agricultural sectors
have opted for tension springs made at our plant. Continuous development in the process of production of tension springs has led to complete satisfaction and long-term cooperation with our customers. The tension springs are manufactured on the automatic machines of the world-renowned Wafios brand, which at the same time leads to a very high accuracy of the springs.
We manufacture tension springs with different end types, depending on the needs of spring assembly in equipment.
- tension springs with an English coupling
- tension springs with an German coupling
- tension springs with a hook coupling
- tension springs with a swivel coupling
Tension springs are characterized by a high expansion coefficient. Depending on the nature of the work of the tension spring, different types of materials are used – so as to meet customer requirements and the correct operation of the entire device.
- spring steel grade SM
- spring steel grade SM
- spring steel grade DH
- spring steel grade 1.4310
What distinguishes our tension springs from the competition?
- long spring fatigue value
- certified materials
- modern heat treatment of springs
- short delivery times
An uninterrupted development process in the field of spring manufacture has enabled us to wind tension springs from rods ranging from 0.30 mm up to 20.00 mm.
We can supply our customers with tension springs in several versions:
- zinc-plated springs, silver or gold color
- springs painted in a RAL color of the customer’s choice
- black springs with oil protection
