Frequently Asked Questions #
What if your components came with eco-conscious packaging – without extra cost?
At DMS Group Taiwan, sustainability is standard. We use recyclable, minimal-waste packaging to help reduce environmental impact while ensuring your parts arrive protected and ready to use.
What is anodizing and why is it used?
Anodizing is an electrochemical process that thickens the natural oxide layer on metals like aluminum. It provides corrosion resistance, improves wear resistance, and allows for coloring. This is essential for parts exposed to harsh environments, such as aerospace or automotive applications.
What is the difference between polishing and buffing?
Polishing creates a smooth, shiny surface with a reflective finish, while buffing achieves a higher-gloss, mirror-like finish. Buffing is typically used for decorative purposes, while polishing is ideal for smoothness and friction reduction.
What is passivation, and why is it important?
Passivation is a chemical treatment that enhances the corrosion resistance of stainless steel by removing free iron from the surface, preventing rust and oxidation. It is commonly used in medical, aerospace, and food industries for parts requiring hygiene and long-term durability.
What is the benefit of a brushed (satin) finish?
A brushed or satin finish creates fine, uniform lines across the surface, giving it a matte look. It is especially suitable for stainless steel, as it reduces fingerprints, hides scratches, and adds a modern, professional aesthetic.
What is powder coating and why is it used?
Powder coating is a dry coating process where powder is applied electrostatically and then baked. It provides a thicker, more durable finish than liquid paint and is resistant to chipping, scratching, and fading, making it ideal for outdoor and industrial applications.
What is electroplating, and why is it important?
Electroplating coats a metal surface with a thin layer of another metal (e.g., chrome, gold) to enhance corrosion resistance, hardness, or aesthetic appeal. It is widely used in electronics, jewelry, and automotive parts for both protection and appearance.
