Designed for high temperature, vacuum, and precision optical applications



Custom Metal Aperture Discs: Your Guide to OEM Precision Machining
In the world of precision engineering, "standard" parts rarely fit "critical" applications. Whether you are designing a new optical sensor, a laser alignment module, or a vacuum chamber component, off-the-shelf components often fail to meet the specific geometric or material requirements of your system.
At our factory, we don't just sell parts; we engineer solutions. As a leading custom metal disc manufacturer, we specialize in transforming complex concepts into tangible, high-precision reality. We understand that for R&D teams and procurement specialists, flexibility is just as important as accuracy.
Beyond Standard: Total Customization Capabilities
Our manufacturing philosophy is simple: if you can draw it, we can make it. We utilize a combination of Chemical Etching, CNC Machining, and Laser Cutting to offer a level of customization that traditional stamping cannot match.
1. Dimensional Precision
We push the boundaries of micro-machining. Our capabilities allow us to produce custom aperture slits and holes with diameters as small as 0.1mm. Whether you need a thin shim or a thick structural disc, we maintain tight tolerances (typically ±0.01mm to ±0.02mm) to ensure the part fits your assembly perfectly.
2. Geometric Freedom
Unlike mechanical punching, which is limited by tool wear and shape constraints, our chemical etching process allows for complex geometries without increasing costs.
- Complex Apertures: Flower shapes, slots, or irregular polygons for specific diffraction control.
- Half-Etching: We can create countersunk features or folding lines on the same part without secondary operations.
- External Profiles: Intricate outer shapes with alignment notches or tabs.
3. Material Versatility
While we are known for our expertise in refractory metals, our supply chain is extensive. We process a wide range of materials to suit your environmental needs:
- Molybdenum & Tungsten: For high-temperature and vacuum applications.
- Stainless Steel (SUS301, SUS304, SUS316): For general corrosion resistance and durability.
- Copper & Brass: For electrical conductivity and EMI shielding.
- Aluminum & Kovar: For lightweight or thermal-matching applications.
From Prototype to Production: Our Process
We know that speed is critical in product development. As a provider of rapid metal prototype service, we have streamlined our workflow to support you from the initial concept to mass production.
- DFM Analysis: When you send us your CAD files, our engineering team performs a Design for Manufacturability (DFM) analysis. We identify potential risks—such as stress concentrations or tolerance stack-ups—and suggest optimizations before we cut any metal.
- Rapid Prototyping: For OEM precision parts, we prioritize speed. We can often produce samples within days, allowing you to test and validate your design quickly.
- Scalable Production: Whether you need a single custom disc for a lab experiment or 10,000 units for a commercial product launch, our Shenzhen precision machining lines are equipped to scale with your demand.
Featured Solution: The Custom OEM Approach
A prime example of our capability is our work with Custom Molybdenum Aperture Plates.
A client recently needed a specialized metal disc for a high-vacuum electron microscope. The requirements were strict: a specific alloy to match thermal expansion rates, a complex internal slit to shape the electron beam, and absolute cleanliness.
- The Challenge: Standard machining left burrs that interfered with the beam, and the material was difficult to source.
- Our Approach: We utilized our chemical etching line to process the custom molybdenum alloy. This ensured a burr-free edge and perfect dimensional stability. We also applied a specialized cleaning process to remove all organic contaminants.
- The Result: The client received a fully functional, vacuum-compatible custom metal disc that integrated seamlessly into their system.

Questions and Answers
Frequently Asked Questions (FAQ)
Q: What file formats do you accept for custom quotes?
We accept standard CAD formats including .DXF, .DWG, .STEP, and .IGES. For the most accurate quote, please include material specifications and tolerance requirements.
Q: Do you support low-volume orders for prototyping?
Yes. We understand that R&D projects often start small. We are fully equipped to handle low-volume orders and custom prototypes with the same attention to quality as our mass production runs.
Q: Can you customize the surface finish of the discs?
Absolutely. Depending on the material and application, we can provide black oxide coating, gold plating, passivation, electropolishing, or specific surface roughness treatments to reduce glare.
Q: How do you ensure quality in mass production?
We employ rigorous Quality Control (QC) measures, including optical projection inspection and CMM (Coordinate Measuring Machine) testing, to ensure every batch matches the approved sample specifications.
