Surface Protection Solutions for Industrial Components & Conveyor Chains
At MaTech, we deeply integrate surface treatment capabilities into our casting, CNC precision machining, heat treatment, and conveyor chain production systems, providing customers with complete manufacturing and surface protection solutions. Based on material type, service environment, and performance requirements, we can match suitable surface treatment processes for steel castings, iron castings, aluminum alloy castings, and conveyor chains. This enhances product reliability and durability under humid, high-wear, corrosive, and heavy-load operating conditions.
Why Choose Matech for Surface Finishing Service?
In industrial component manufacturing, surface treatment not only affects product appearance, but also directly impacts corrosion resistance, wear resistance, and long-term operational reliability. When surface treatment processes are outsourced from multiple suppliers, issues (such as extended logistics time, unclear quality responsibility, uneven coating thickness, and poor adhesion) often arise.
Matech integrates common surface treatment processes within a single quality management system, achieving seamless, coordinated manufacturing from raw material production, precision machining, and heat treatment to final surface protection. Equipped with professional testing equipment—including coating thickness gauges, salt spray chambers, and adhesion testers—we ensure consistent and controllable quality for every batch. By providing your product drawings and performance requirements, our engineering team can develop a tailored surface treatment solution, balancing manufacturability with long-term reliability.

At Matech, surface treatment is not merely a post-processing step – it is an integral part of overall manufacturing quality and product reliability. We deeply integrate surface treatment capabilities with casting, CNC precision machining, heat treatment, and conveyor chain production, to provide long-term, stable surface protection solutions for industrial components. Share your drawings or technical requirements and engage with our engineering team for further consultation.
Surface Treatment Capabilities
We divide our surface treatment services into four main areas: pre-treatment capabilities, core process capabilities, testing capabilities, and support services.
Process Validation & Sample Testing: For new materials, new drawings, or special requirements, sample parts are produced and subjected to a full range of performance tests (including adhesion and salt spray), to validate process feasibility before moving to batch production, thereby reducing trial-and-error costs.
Selective Protection & Masking: Precision masking is applied to non-treatment areas, precision threads, bearing seats, sealing surfaces, and other critical zones. Using high-temperature resistant tape, dedicated fixtures, or peelable coatings, to ensure clear boundaries and no seepage or plating deposition.
Custom Hanging Tool Design: Dedicated hanging tools are designed for irregularly shaped parts or high-volume products, to optimize part orientation and electrical contact points, balancing coating uniformity with production efficiency while minimizing hanging marks and other surface defects.
Environmental Compliance & Documentation: Full compliance with RoHS, REACH, and other environmental regulations, with third-party test reports available from accredited laboratories.

Frequently Asked Questions
1
What are the main advantages of Dacromet coating compared to galvanizing?
Compared with conventional galvanizing, Dacromet coating provides superior corrosion resistance and significantly better salt spray performance. It also reduces the risk of hydrogen embrittlement, making it especially suitable for high-strength fasteners and chassis components.
2
What colors are available for anodized aluminum alloys?
Standard anodizing can produce a variety of colors, including black, blue, red, gold, and green. Hard anodizing typically results in a dark gray or dark brown finish, with greater emphasis on improving wear resistance and surface hardness.
3
Does surface treatment affect the dimensional accuracy of parts?
Yes. Processes such as zinc plating and Dacromet coating add a certain thickness(approximately 5–15 μm), while anodizing involves a combination of embedded and grown layers (resulting in a total increase of about 50% of the film thickness). For precision mating surfaces, appropriate machining allowances should be considered, and we can provide recommendations during the DFM stage.
4
Do stainless steel parts require surface treatment?
Depending on the operating environment and performance requirements, some stainless steel components still require surface treatment. For example, passivation improves corrosion resistance, electropolishing enhances surface cleanliness and stability, and surface hardening improves wear resistance. Especially after welding, machining, or in heavy-duty operating conditions, proper post-treatment helps improve long-term product reliability.
