Product Description
1. Classification and Characteristics of Coating Service Technologies
In today's competitive manufacturing landscape, the advantages of utilizing a customized injection molding service are increasingly evident for businesses seeking precision and efficiency.
One of the primary benefits of such a service is the ability to produce parts with exceptional design flexibility, allowing for complex geometries and specific material properties tailored to unique applications. By partnering with a provider offering a reliable customized injection molding service, companies can achieve significant cost savings through optimized production runs and reduced material waste.
Furthermore, this approach ensures consistent high quality and rapid prototyping capabilities, accelerating time-to-market for new products. The scalability of a professional customized injection molding service makes it an ideal solution for both low-volume and high-volume manufacturing needs.
Ultimately, engaging a dedicated customized injection molding service empowers businesses to enhance product performance and maintain a strong competitive edge in their respective industries.
PVD Coating (Physical Vapor Deposition)
- Process Characteristics : Thin films are deposited in a vacuum environment by evaporation or sputtering of the target material, with film thickness of 1-10μm, hardness up to HV2000-4000, and temperature resistance of 300-800℃.
- Advantages : Environmentally friendly and pollution-free, high wear resistance, various colors (such as gold, black, rose gold, etc.).
- Applications : Cutting tools (TiN coating extends life by 3-5 times), medical devices (DLC coating friction coefficient ≤0.1), automotive parts (piston ring CrN coating).
CVD Coating (Chemical Vapor Deposition)
- Process Characteristics : Gaseous reactants chemically react on the substrate surface to form a film, suitable for complex-shaped workpieces, with a relatively high deposition temperature (850-1100℃).
- Advantages : Good conformality, dense film, capable of preparing superhard coatings such as carbides/nitrides.
- Applications : Semiconductor insulation layers (SiO₂), cutting tools (TiC coating life increased 4-8 times).
Automotive Beauty Coating
- Types :
- Inorganic Nano Coating : High hardness (alumina/silica components), UV resistant, acid and alkali resistant, maintains mirror effect for over 1 year.
- Glass Cellulose Coating : High gloss, isolates external corrosion, priced over a thousand yuan per vehicle.
- Process : Deep cleaning → Polishing → Coating application → Infrared baking.
2. Industry Application Cases
Industrial Field
- Aerospace : Ion-plated aluminum on titanium alloy fasteners to solve cadmium brittleness issues.
- Electronic Components : PVD prepares semiconductor conductive layers (such as copper/aluminum), CVD deposits polysilicon gates.
Consumer Field
- Automotive Beauty : Basic coating for scratch resistance (UV and acid rain protection), advanced coatings enhance color effects.
- Decorations : PVD rose gold coating on watch cases, colorful coatings on phone cases.
New Energy and Medical
- Photovoltaics : CVD prepares solar selective absorption films (α=1, infrared emissivity=0).
- Medical Equipment : Stainless steel electrolytic polishing + SUS304 antibacterial oxide film (Ra ≤ 0.4μm).
3. Core Competency Comparison of Service Providers
| Capability Dimensions | Advantages of Large Enterprises | Characteristics of Small and Medium Enterprises |
|---|---|---|
| Mass Production | Monthly capacity of 500,000 pieces (fully automated PVD line) | Flexible order acceptance (minimum 100 pieces) |
| Customization | Provides FEA simulation + material matching tests | 72-hour rapid prototyping |
| Environmental Technology | Zero wastewater discharge system | Chromium-free passivation process (RoHS certified) |
4. Selection Suggestions and Precautions
Material Compatibility
- Aluminum alloys 6061/5052 are suitable for anodizing; titanium/stainless steel prefer PVD.
- Car paint surfaces need polishing to repair scratches before coating.
Process Selection
- High wear resistance requirements : Hard PVD (TiAlN) or CVD carbide coatings.
- Complex shapes : CVD conformality is better than PVD.
Quality Control
- Mandatory tests: film thickness (eddy current meter), adhesion (cross-cut test), salt spray test (≥500h).
5. Technology Development Trends
- Intelligentization : AI optimizes PVD deposition rate, film thickness uniformity ±0.1μm.
- Low-temperature Process : Plasma-assisted CVD reduces temperature to 600K.
- Composite Coatings : PVD multilayer structures (e.g., TiN+MoS₂) reduce friction coefficient.
