Custom CNC Machining Service, 6061 Aluminum Precision Cavity Housing for Semiconductor Equipment OEM Components

This precision cavity housing is custom manufactured by our CNC machining service. We select high-quality metal materials as the core foundation to guarantee stable mechanical performance, vacuum suitability and surface finish for semiconductor equipment assemblies. Strict material inspection is implemented before production, to avoid material defects that may affect dimensional tolerance and service life.

✦ Highlight note:Material performance is the first guarantee for semiconductor vacuum components.

We take material control as our core advantage. Different materials bring completely different performance for your cavity parts:

1. 6061-T6 Aluminum (Our mainstream material for this cavity housing) Good machinability, moderate strength, low outgassing property, lightweight and excellent thermal conductivity. It is widely adopted in semiconductor vacuum assemblies.

✦ Highlight note:Low outgassing is critical for semiconductor vacuum environment.

2. High-precision CNC machining characteristics Our 5-axis CNC equipment completes complex inner cavity, threaded holes, positioning notches and mating surfaces in one clamping. It reduces cumulative clamping error and ensures coaxiality and flatness of the cavity. Internal burrs are fully removed to prevent particle pollution inside the chamber.

✦ Highlight note:One-setup machining ensures consistent precision for complex cavity structure.

3. Custom material diversification capability We are not limited to aluminum alloy. According to your working environment requirements, we can switch to other raw materials:

• 7075 aluminum: higher strength, suitable for high-load structural cavity
• 316L stainless steel: corrosion resistance, suitable for special gas / wet process environment
• PEEK: high temperature resistant non-metal cavity for special insulation demand

✦ Highlight note:We support material substitution based on your working condition requirements.

4. Other core strengths

• Strict first article inspection & full dimension report available upon request
• Clean packaging for semiconductor-grade parts to avoid contamination
• Support prototype small batch and mass continuous production
• Custom surface treatment to meet anti-corrosion, wear-resistant or low-reflection demands

This precision cavity housing component is designed for semiconductor equipment. ✅ Semiconductor vacuum chamber modules ✅ Wafer processing & test equipment ✅ Precision automation & optical inspection instruments ✅ New energy and aerospace precision fluid chamber parts

✦ Highlight note:Suitable for high-cleanliness, high-precision closed cavity assembly.

Q1: What materials can you use to make this cavity housing? A: Standard material is 6061-T6 aluminum. We also support 7075 aluminum, 304/316L stainless steel, brass, PEEK, POM and other engineering plastics. You can select materials according to pressure, temperature and vacuum requirements.
