Increase profitability and quality by upgrading your anodizing process with us.
Thinner coatings
Compared to other coating methods, the anodizing process establishes thinner coats on the surface of the substrate. This quality makes it useful for use on precision machined parts, as the coating thickness does significantly affect part size.
Longer lasting color
As materials that undergo the dyed anodizing process display long-lasting color that is highly resistant to UV radiation and fading, they are ideal for use in outdoor applications.
Smaller environmental impact
With advanced sewage system, waste water generated from the anodizing production process is treated as clean as possible. Additionally, we use environmentally friendly chemicals.
Higher durability
Anodized surfaces display exceptional hardness and abrasion resistance, especially when compared to paint and powder coats. Anodized material is less likely to scratch, chip, or flake, resulting in much longer service life.
Greater corrosion resistance
Anodized surfaces are highly corrosion resistant, making them particularly useful for applications regularly exposed to water, salt spray, and other corrosive substances.
Lower cost
The price of anodizing metals is on par with other coating processes, such as painting and powder coating. The enhanced durability of the anodized finish ensures a longer component lifetime, thereby reducing the cost of maintenance.
Feel The Value Stream In TDC Production
Raw Material of Stainless Steel
Value: Stable properties, suitable for bending and forming
Selecting the materials of materials cost
Most products use Q195. If the material hardness requirements and functional test requirements are high, Q235 is selected, and if the corrosion resistance (such as humidity, food contact environment) or the surface is smooth and shiny, the stainless steel material is selected.
Stamping Process
Value: Multiple stamped lines for 30% efficiency up
Stamp on stainless steel small sheet to get hinge parts. Stamped hinges offer high quality, precision, and at lower cost than machined or extruded hinges, due to the efficiencies of progressive die metal stamping.
Piercing Process
Value: Precise and quick process
Cutting holes in hinge through press machines.
Anodizing Process
Value: 20% finishing cost lower & 30% surface effect up
Our hinges are anodized through advanced automated equipment by our professional team. Quality and stable anodizing finish is one of our advantages comparing to our competitors.
Automatic Assembly
Value: Save 10% on labor cost and 10% Improvement in quality
Automated assembly machines responsible for multiple set of hinges at a time. No extra labors needed and highly under controlled.
Quality Inspection of Semi-product
Value: Keeps semi-products under quality standard
100% inspecting the finish, the cup, the holes, the pumps and the sharp edge whether they are passed for next operations.
Innovative Packaging
Here’s something new invented by Maxave. With our creative boxing methods that utilize the max room of regular box, we save shipping cost and improve shipping efficiency.
Value: 20% packaging room saved & 5% shipping cost cut

Raw Material Control
What values do you look for in a company? The following values are at the heart of our company DNA. They guide the way that we work with our clients and with each other at every level of our organisation. These values represent the foundations for creating wonderful furniture hardware. Material control procedures also allow for effective raw material traceability which is essential for guaranteeing product quality and performance claims. We have a close rapport with our preferred suppliers who understand our quality requirements and work with us to assure materials meet our high standards.
-
Manufacturing Control
Manufacturing procedures are established for each individual product. Throughout the manufacturing and packaging stages there are in-process checks to make sure all products are being manufactured to meet specified parameters. Standard Operating Procedures govern each manufacturing operation and are routinely reviewed to maximize efficiency while maintaining quality. Line clearances and room clean up are done at the conclusion of each run, to keep each patch of products are under good preservation.
