Compression and extension springs
Coiled springs for axial loading — wire diameters from 0.2 to 12 mm, cylindrical or conical geometries to specified load and travel curves. Compression and extension springs cover the bulk of axial loading applications — from fine instrumentation springs in audio and tech equipment to heavier industrial springs in fitness and appliance components. We work with wire diameters from 0.2 to 12 mm, in spring steel, stainless steel and music wire grades, with geometries ranging from standard cylindrical to conical, barrel and hourglass forms. Load and travel curves are specified together with the geometry — not derived from it after the fact. That means the spring meets the function, and the function is documented for traceability across the production run. Typical applications include valve assemblies, mechanical actuators, instrumentation components and load-bearing parts in appliance, fitness and audio equipment.

Torsion and shaped springs
Torsion springs, leg springs and custom-formed wire components for rotational loads and complex geometries. Torsion and shaped springs handle the applications where standard coil geometry is not the answer — rotational loads, hinge mechanisms, custom wire forms with bends, hooks and integrated mounting features. We design the leg geometry, hook configuration and mounting features as part of the spring itself, eliminating the secondary fabrication steps that often follow when springs are sourced as standard catalogue items. The result is a single component that drops directly into the assembly without intermediate fitting work. Typical applications include hinge assemblies, latch mechanisms, return springs and custom wire components for design furniture, lighting fixtures and appliance hardware.

Heat treatment and finishing
Stress relief, hardening, tempering and surface treatment integrated into the same delivery — spring arrives load-tested and ready for assembly. A formed wire is rarely the deliverable. It needs to be stress-relieved or fully heat-treated to set its mechanical properties, surface-treated for corrosion protection, load-tested against the specification curve, and often combined with other components before it reaches the production line. We integrate these operations into the same job, scheduled and documented as one flow rather than three separate sub-contracts. Heat treatment, surface coating and load testing run on the same QA chain as the forming itself, with material certification preserved end to end. For you, that means one purchase order, one point of contact and one set of inspection records — instead of coordinating multiple suppliers and absorbing the lead time between them.

Engineered before
it's wound.
Design for manufacturing
Most spring specifications come in as a finished drawing — geometry locked, material chosen, load curve assumed. Too often the assumptions don't survive contact with the actual application, and the spring either fails on test or costs more than it should because the design fights the manufacturing process.
​
We bring spring engineering into the conversation early. Before the wire is selected, our engineers review the load case, travel requirements, fatigue cycle, end-condition geometry and integration with the surrounding assembly — the decisions that determine whether the spring performs reliably and whether it is economical to produce.

The earlier we're involved, the more we can remove from your cost and rework. A 30-minute DFM session often saves weeks of iteration later.

CNC is rarely a standalone process. We combine it with casting, forming and finishing to deliver complete components — often in a single purchase order.
Spring manufacturing as one link in a complete supply chain.
Most suppliers sell springs as a catalogue item or a stand-alone component. We don't. At Pamatek, spring manufacturing sits inside an integrated flow that runs from wire selection through forming and heat treatment to surface finishing, assembly and logistics — managed by one team, documented through one QA chain, delivered on one purchase order.
​
That's the difference between buying a spring and buying a finished assembly where the spring is engineered into the function — with material, geometry and load characteristics specified together rather than negotiated separately.
