Torsion springs generate a controlled moment against rotational movement, storing energy through angular deflection and returning the mechanism to its set position. Maktel produces torsion springs from 0.20 to 9.00 mm wire diameter for automotive, defence, appliance, electrical-electronic, machinery, lock mechanism, hinge system and actuator applications.
Product range
We produce single and double torsion springs, right and left wound, open or close-wound, in round wire, multi-strand wire and, for suitable projects, square-section material. Straight, angled, radial, axial, short or extended arms; hooked or bent ends; symmetric and asymmetric double-torsion geometries and custom end forms are produced to your drawing — arm length and geometry directly affect moment characteristics and installation performance.
Design and engineering support
We evaluate wire diameter, number of coils, M1/M2 moment values, working and free angle, inner/outer diameter, hub/pin diameter, winding direction, arm lengths and angles together with the installation space; cycle count, temperature, corrosion and mechanical load conditions guide the design. Engineering support on material, moment characteristics, arm geometry and manufacturability is provided from technical drawings, samples or functional data.
Material, heat treatment and quality control
We use EN 10270-1 DH class patented wire, EN 10270-2 Cr-Si high-tensile wire, oil-tempered wire, high-tensile stainless wire, multi-strand/rope-type wire and square-section materials. Stress relieving, thermal stabilisation, shot peening and application-specific surface treatments are applied. Dimensional checks, angle checks and force/moment tests are carried out in-house; approved products are packed in line with traceability requirements.
