Precision Metal Machining Solutions
Specializing in Hard-to-Cut Materials, Vacuum Components, and Surface Treatment Integration — Ensuring High-Specification Process Precision
In semiconductor and high-tech manufacturing processes, metal components require not only micron-level dimensional precision but also exceptional corrosion resistance, high vacuum airtightness, and low particle generation characteristics. We offer a one-stop integrated service encompassing material selection, precision CNC machining, and Surface Treatment.
Distinct from general machine shops, we are deeply rooted in the semiconductor equipment sector, specializing in the precision manufacturing of hard-to-cut materials such as Titanium, Nickel-based alloys (Hastelloy, Inconel), and Molybdenum. For critical components within vacuum chambers, acid/alkali-resistant electrodes, or structural parts, we execute precision machining based on customer specifications (Build to Print). Furthermore, we fully support R&D teams with small-batch prototyping and testing, ensuring components demonstrate exceptional performance under rigorous process environments.
Our Service Scope
Equipped with mill-turn compound machining, grinding, and welding technologies, we provide optimal processing solutions tailored to different metal characteristics:
Specializing in the precision machining of high-hardness and high-toughness materials such as Titanium, Hastelloy, Inconel, and Molybdenum.
Precision milling and turning of materials such as SUS316L and SUS304 to manufacture key chamber consumables, flanges, and piping fittings, paired with Electropolishing (EP) to ensure high cleanliness.
Providing precision structural machining for A6061/A7075 aluminum alloys and Oxygen-Free High Conductivity Copper (OFC), suitable for electrode heads, thermal modules, and lightweight carriers.
Integrating post-processing services such as Anodizing, Hard Anodizing, Electroless Nickel, Black Nickel, Teflon Coating, Gold Plating, and Silver Plating to simplify your procurement process.
Core Advantages (Why SY Tech?)
1. Technical Strength in Mastering "Hard-to-Cut" Materials
Titanium and Nickel-based alloys often cause tool wear or dimensional instability due to severe work hardening. We possess an extensive database of machining parameters and special tooling configurations to overcome material characteristics, achieving tolerances of ±0.01mm for Titanium and Hastelloy (depending on part structure).
2. Flexible Support for R&D Development & Testing
We understand the "low volume, fast iteration" needs of the R&D phase. Whether it is single-piece Prototyping or small-batch trial production, we are willing to work with engineers for testing and verification, assisting you in solving feasibility issues in structural design.
3. Semiconductor-Grade Surface Quality Control
The value of metal parts often depends on "Surface Treatment." We strictly control our partner surface treatment facilities to ensure complete pore sealing in anodization and smooth Electropolished (EP) surfaces, avoiding process contamination caused by coating peeling or chemical residue.
4. Strict Internal QC Standards
Our factory is equipped with 2.5D vision measuring instruments and high-end measuring tools to perform full inspections on critical dimensions. From confirming raw material hardness to final product dimensional tolerances, we execute rigorous quality inspection procedures to ensure shipment yield rates.
Solving Common R&D and Process Challenges
We assist you in solving various "physical challenges" in material applications:
| Common Field Challenges | Our Solution |
|---|---|
| Metal corrosion in acid/alkali tanks leading to process contamination | We suggest switching to Titanium or Hastelloy. These materials possess excellent resistance to strong acids and alkalis, with a lifespan far superior to standard stainless steel. |
| Poor airtightness in vacuum components (Leak Issue) | Ensuring flatness and roughness (Ra) of the Sealing Surface through precision machining, paired with Electropolishing (EP) to reduce gas adsorption and improve vacuum performance. |
| Part softening and deformation in high-temperature environments | Introducing Molybdenum or Inconel heat-resistant alloys to ensure structural rigidity is maintained in furnace processes exceeding 1000°C. |
| Aluminum parts scratching easily or generating particles | Performing high-hardness Hard Anodizing or Electroless Nickel plating to significantly improve surface hardness and wear resistance, preventing particle generation. |
| Cannot find a vendor willing to accept R&D sample orders | We fully support low-volume R&D prototyping. Whether it's a single screw or a set of critical components, we provide professional machining services and advice. |
