Mini Stainless Steel Tension Spring | 30mm Durable High Elasticity

Product Description

The Mini Stainless Steel Tension Spring is a high-precision extension component designed for delicate mechanical assemblies that require consistent return force and exceptional durability. With a standard overall length of 30mm, these miniature springs are engineered to provide a reliable "Precision Reset" function in compact spaces where standard-sized springs simply cannot fit.

Manufactured by the METS Team, each spring is crafted from premium-grade 304 or 316 Stainless Steel, ensuring superior corrosion resistance and high elasticity. The coils are tightly wound with a controlled initial tension, allowing the spring to maintain its structural integrity and performance even after millions of expansion cycles. Whether it is for the paper feed mechanism in a high-speed printer or the intricate components of a consumer electronic device, our mini tension springs deliver the consistent performance that global OEMs and manufacturers demand.

Key Features

• High-Precision Elasticity: Optimized for a smooth, linear spring rate, providing accurate and predictable tension throughout its working stroke.

• Superior Corrosion Resistance: Made from high-quality stainless steel, making it ideal for use in humid or challenging industrial environments without rusting.

• Miniature & Compact: At 30mm in length, it is specifically designed for micro-mechanisms and precision instruments.

• Durable English Loops: Features standard circular hooks (loops) that are meticulously formed to prevent stress concentration and ensure secure attachment.

• Smooth Surface Finish: Precision-polished to reduce friction and noise during operation, enhancing the overall lifespan of the host device.

Technical Parameters

Industrial Applications

These small-scale tension springs are critical for the seamless operation of various high-tech devices:

• Office Automation (OA): A core component for printers, scanners, and photocopiers, specifically in paper-tray sensors, feed rollers, and scanning head return mechanisms.

• Consumer Electronics: Used in gaming controller triggers, camera shutter assemblies, and retractable cable systems.

• Medical Instrumentation: Integrated into surgical tools, diagnostic equipment, and fluid control valves where hygiene and precision are mandatory.

• Automotive Sensors: Found in small latch assemblies, mirror adjustment motors, and interior switchgear.

• Precision Hardware: Used in high-end locks, telecommunication devices, and micro-switch components.

Customization Services

The METS Team provides comprehensive "B2B Customization" for your specific engineering blueprints:

• Dimensional Customization: We can adjust the wire diameter, coil count, and hook height to achieve the exact spring constant ($k$) required for your device.

• Hook Angle & Style: Choose from crossover center loops, side loops, or extended hooks at specific angles (e.g., 90° or 180°).

• Material Grading: Beyond standard 304, we offer 316 stainless steel for medical/marine use or music wire for high-cycle applications that don't require rust-proofing.

• Force Testing: We provide load-deflection charts to verify that each custom batch meets your exact force specifications.

Support and Services

• Engineering Consultation: Our team assists in calculating the required force and material stress levels to optimize your spring design.

• Small-Batch Prototyping: Rapid sample production (7-10 working days) to help you validate your prototype before mass production.

• Strict Quality Control: 100% inspection of critical dimensions and load testing to ensure batch-to-batch consistency.

Packing and Shipping

• Bulk Packaging: Packed in moisture-proof polybags and high-strength cartons to ensure safe arrival.

• Tape & Reel: For automated assembly lines, we offer specialized carrier tape packaging (upon request).

• Fast Global Shipping: Reliable export via Air (Express DHL/FedEx/UPS) or Sea Freight for large-volume B2B orders.

FAQ

Q: What is the benefit of using 304 Stainless Steel for these springs?

A: 304 Stainless Steel offers a perfect balance of high tensile strength and excellent corrosion resistance, ensuring the spring remains functional even in environments exposed to moisture or chemicals.

Q: Can you produce springs with a specific "Initial Tension"?

A: Yes. We can adjust our CNC winding parameters to provide more or less "initial tension" (the force required to start separating the coils) based on your mechanical needs.

Q: What is the typical lead time for a custom order?

A: Standard samples take 7-10 days, while mass production typically takes 12-18 working days depending on the volume.

Q: Do you offer RoHS or REACH certification?

A: Yes, all our stainless steel materials are fully compliant with RoHS and REACH environmental standards.
