What is Tubular Formed Components？

Tubular formed components are metal parts created by precision forming of tubes into complex 3D geometries, featuring lightweight hollow structures. Widely used in automotive exhausts, medical catheters and aerospace fluid systems.Stainless Steel Compression Springs

Key Advantages

Lightweight

40-60% weight reduction vs solid parts with maintained strength.

Flow Optimization

Ra0.1μm inner surface reduces fluid resistance by 30%.

Integrated Structure

Forms multi-branch/variable-diameter systems in one piece.

Material Efficiency

Cold forming saves 50% material vs machining.

Fatigue Life

Strain hardening extends service life 3-5x.

How They Work

Compression springs operate based on Hooke’s Law (F = -kx), where the force exerted is proportional to the displacement. When an external load is applied, the spring’s coils compress, storing elastic potential energy. Upon release, the stored energy causes the spring to rebound to its original shape.

Key Characteristics

✔️

Size Range - Processes 0.5-300mm diameter tubes with 0.1-15mm walls

✔️

Forming Accuracy - ±0.05mm diameter, ±0.5° angle tolerance

✔️

Surface Quality - Achieves medical-grade Ra0.4μm finish

Key Design Factors

✔️

Thinning Control – Limits thinning to 80% of material elongation

✔️

Die Clearance – Maintains 1.1-1.3x wall thickness gap

✔️

Lubrication – Food-grade lubricants for medical/food applications
