0.075mm Gold-Plated Tungsten Wire Medical Micro Springs | Sichuan Winner

Ultra-Fine Precision. Advanced Materials. Engineered for Medical Innovation.

Precision at Just 75 Microns

In the rapidly evolving medical device industry, miniaturization, precision, and material reliability are becoming increasingly important.

As medical technologies advance, manufacturers require smaller and more sophisticated components that can meet demanding dimensional and functional requirements.

At Sichuan Winner, we focus on ultra-fine metal wire processing and customized precision spring solutions.

Our 0.075mm (75μm) Gold-Plated Tungsten Wire Micro Springs combine the distinctive material properties of tungsten with precision micro-coiling technology and gold-plated surface finishing, offering potential solutions for specialized medical device components.

With a wire diameter of just 75 microns, these miniature springs demonstrate the possibilities of micro-scale manufacturing.

Why Choose Gold-Plated Tungsten Wire?

Tungsten is a high-density metal recognized for its extremely high melting point, mechanical strength, and dimensional stability.

When combined with a gold-plated surface, tungsten wire can provide additional electrical contact and surface characteristics that may be useful in specialized miniature components.

Key Material Advantages

• Ultra-Fine Wire Diameter: 0.075mm (75μm), suitable for compact spring geometries.

• High-Density Tungsten Core: Offers distinctive material properties for specialized precision designs.

• Precision Gold-Plated Surface: Provides a conductive surface for applications requiring electrical contact.

• Micro-Coiling Capability: Enables the development of miniature spring structures.

• Customizable Specifications: Spring dimensions, coil pitch, number of turns, and plating thickness can be tailored to customer drawings.

Final material suitability depends on the specific medical device design, operating conditions, and validation requirements.

Precision Manufacturing for Medical Device Components

Manufacturing miniature springs from 0.075mm tungsten wire requires careful control of multiple processing parameters.

Wire tension, coil diameter, pitch consistency, surface condition, and plating integrity can all influence the performance of the finished component.

For medical device applications, dimensional consistency and traceable quality requirements may be particularly important.

Depending on customer specifications, evaluation may include:

• Dimensional inspection and microscopic examination

• Surface quality and coating integrity assessment

• Spring force and mechanical performance testing

• Fatigue and durability evaluation

• Material identification and traceability

• Application-specific cleanliness and biocompatibility assessment

Testing requirements should be defined according to the intended application and applicable regulatory standards.

Potential Applications in Medical Technology

0.075mm gold-plated tungsten wire micro springs may be evaluated for specialized medical device applications, including:

1. Miniature Medical Instrument Components

Precision springs may be used in compact mechanisms requiring controlled movement and repeatable mechanical response.

2. Medical Electrical Contact Assemblies

Gold-plated wire surfaces may offer advantages in certain low-current electrical contact designs.

3. Medical Sensor Components

Miniature spring structures may be considered for specialized sensor assemblies requiring compact mechanical or electrical interfaces.

4. Diagnostic Equipment

Ultra-fine precision springs may support the development of miniature components used in laboratory and diagnostic instruments.

5. Customized Medical Device Mechanisms

Application-specific micro springs can be developed according to customer drawings and technical requirements.

These are potential engineering applications, not claims of clinical suitability or regulatory approval.

Quality Considerations for Medical Applications

Medical device components may require additional quality controls beyond those used for general industrial products.

Depending on the intended use, manufacturers may need to evaluate material compatibility, coating durability, cleaning processes, particulate generation, sterilization compatibility, and biological safety.

For patient-contacting applications, biological evaluation may be required under the applicable ISO 10993 framework.

Medical device manufacturers are responsible for determining the appropriate regulatory pathway, risk management requirements, and validation activities for their finished devices.

Sichuan Winner's gold-plated tungsten wire micro springs should not be considered certified for medical implantation or patient contact without the necessary application-specific testing and approval.
