We are a professional manufacturer for custom compression springs. This cylindrical helical compression spring is fabricated from SWC / SWPB carbon spring steel wire and finished with nickel plating for corrosion resistance.

The production process includes CNC spring coiling, stress relieving tempering heat treatment, end grinding, deburring, full dimensional inspection and nickel plating. Our custom service allows adjusting wire diameter, outer diameter, free length, coil count and surface treatment according to your engineering drawings or physical samples. Suitable for compact mechanical assemblies requiring stable elastic force and reliable repeated compression performance.

This small precision compression spring is widely used in small electronic devices, household appliances, office equipment, automation components, medical instruments, sensors, pneumatic fittings and consumer hardware assemblies for pressure holding, buffering, resetting and elastic supporting.

We provide full custom & OEM service for compression springs. You can send your technical drawings or physical samples for quotation. We support custom adjustment on material selection, wire diameter, outer diameter, free length, coil number, end type and surface coating. Our CNC spring workshop can produce prototype samples and mass production orders for your project.

• Consistent elastic performance: Heat treatment removes internal stress to prevent spring fatigue and force decay during repeated compression.
• High dimensional precision: End grinding & full inspection solves uneven end face and size deviation issues.
• Nickel plated surface: Improves rust resistance and surface conductivity, avoids oxidation in humid working environment.
• Flexible custom support: No need to compromise your design; we manufacture springs strictly matching your drawing requirements.
• Reliable batch stability: Mass production keeps uniform quality for all spring units.

• Raw material incoming inspection to verify steel wire mechanical property.
• In-line dimension check during CNC spring coiling.
• Post heat treatment hardness & elasticity testing.
• 100% dimension inspection after grinding and deburring.
• Surface plating quality inspection before packing.

We implement full quality tracking for every custom compression spring batch.

• Sample order: Samples can be prepared within 3-7 working days after drawing confirmation.
• Mass production: Lead time depends on quantity and custom specifications, normally 10–20 working days.
• Shipping: We support international shipping via DHL, FedEx, UPS, sea freight and air freight. Packed with anti-rust packaging to protect small springs during transit.
