Project Background

A global electronics manufacturer required a reliable supplier to produce miniature sensor contact pins used in electronic equipment.

The component was designed as a critical electrical contact element inside the sensor assembly.

Although the part size was extremely small, its performance directly affected:

• Electrical contact reliability
• Assembly accuracy
• Product stability

The customer provided:

• 2D engineering drawings
• 3D CAD models

Based on the customer's requirements, YS Precision developed a complete manufacturing solution covering:

• Brass material preparation
• Swiss CNC turning
• Precision inspection
• Gold plating
• Export packaging

The project required:

60,000 precision sensor contact pins

with a total production cycle of approximately:

20 days from material preparation to finished delivery.

Project Overview

Manufacturing Challenges

Producing Miniature Precision Components with Consistent Quality

For electronic applications, miniature components often have critical functional requirements.

Although the sensor contact pin is only a few millimeters in size, manufacturing challenges include:

1. Ultra-Small Precision Machining

The part dimensions:

• Maximum diameter: Ø2mm
• Length: 9mm

create challenges such as:

• Material vibration
• Tool accessibility
• Dimensional stability

Swiss CNC turning provides excellent stability for these miniature components.

2. Tight Dimensional Control

The customer required critical dimensions controlled within: -0.01mm / +0mm

This required:

• Stable machining parameters
• Accurate tooling management
• Continuous process monitoring

The goal was not only to produce qualified samples, but to maintain consistent quality throughout: 60,000 production pieces.

3. Functional Gold Plating Requirement

The sensor contact pins required: 0.5μm gold plating

The gold coating was applied to achieve:

• Reliable electrical contact
• Improved corrosion resistance
• Long-term surface stability

Machining quality was critical to achieving consistent plating performance.

YS Precision Manufacturing Solution

Swiss CNC Turning Combined with Complete Manufacturing Management

After reviewing the customer's drawings, YS Precision selected Swiss-type CNC turning as the optimal production method.

Instead of providing machining only, we managed the complete manufacturing process:

Engineering Review

Analyzing:

• Part structure
• Critical dimensions
• Machining feasibility
• Surface requirements

Precision Swiss CNC Turning

Manufacturing miniature brass components with stable repeatability.

Surface Treatment Management

Coordinating gold plating requirements.

Quality Control

Ensuring finished components meet customer specifications.

Why Swiss CNC Turning Was the Right Choice

1. High Stability for Miniature Components

Swiss-type CNC machines use a guide bushing system to support the material close to the cutting area.

This helps reduce:

• Cutting vibration
• Material deflection
• Dimensional variation

2. Excellent Repeatability for Volume Production

For 60,000 pieces, production consistency was critical.

YS Precision controls:

• Tool wear
• Machining parameters
• Inspection frequency
• Process stability

to maintain reliable output.

3. Efficient Manufacturing of Complex Small Parts

Swiss CNC turning can integrate multiple operations:

• Turning
• Grooving
• Chamfering
• Precision forming

Reducing secondary processing and improving consistency.
