Surface Finish

Optional Surface Finish Colors & Textures

Surface finish, sometimes known as surface texture or surface topography, is the nature of a surface as characterized by the three properties of lay, surface roughness and waviness. Specification of surface finish are typically found on technical drawings for mechanical parts, especially where parts have A surface, provide a soft touch, fit together securely, or work in extreme conditions. Each manufacturing process produces a surface texture, and it is quite typical to add an extra process (or multiple processes if required) to modify the initial texture in order to make the resulting texture more practical and affordable for long-term use of product lifecycle.

Upon your component has been designed you may be considering several sorts of surface finishes, and we want to supply you with a finished part that can be placed straightly into your assembly process, rather than a raw part to help you save money and streamline your operation. At GEMS Manufacturing, we offer the ultimate in value-added secondary operations for Surface Finish.

General Advantages Of Applying Secondary Finishing Treatments

Here are some of the general advantages of applying this secondary finishing treatment to a metal or plastic part, including –

  • Increased durability
  • Improved decorative appeal
  • Enhanced electrical conductivity
  • Higher electrical resistance
  • Higher chemical resistance
  • Higher tarnish resistance
  • Potential for vulcanization

Common Surface Treatments

Texturing, Polishing, Anodizing, Bushing, Powder Coating, Oil Spraying, Sand Blasting, Heat Treating, Soft Touching, Chrome Plating, UV painting and so on. Find more details below, or contact us directly to discuss the best surface finish for your application.

  • Polishing
    If you need a smooth, non-textured finish, a buff polishing machine might be the way to go. This machine buffs the product’s surface with a cloth wheel, resulting in a high, glossy finish. The method is frequently used for decorative items that require gloss and smoothness. Buff polishing machines tend to smooth out a product’s edges, and the procedure is less successful for applications requiring delicate, fragile, or recessed features due to the cloth wheel’s range limitations.
  • Anodizing
    Anodizing is an electrochemical technique that turns a metal surface into an anodic oxide finish that is decorative, long-lasting and corrosion-resistant. As known to all, aluminum is ideal for anodizing, other nonferrous metals like magnesium and titanium can be anodized as well. The anodic oxide structure is made completely of aluminum oxide and is derived from the aluminum substrate. This aluminum oxide isn’t applied to the surface like paint or plating; instead, it’s totally merged with the underlying aluminum substrate, so it won’t chip or peel. It has a porous, highly organized structure that allows secondary processes like coloring and sealing to take place.
  • Brushing
    Brush metal finishing, unlike plating, is an effective secondary process for removing surface defects. To smooth out a product’s exterior, this finishing process generates a uniform, parallel grain surface texture. To generate this effect, an abrasive belt or wire brush is frequently used. Furthermore, the belt or brush’s single direction can result in slightly rounded edges perpendicular to the grain.
  • Powder Coating
    Powder coating creates a decorative finish that is similar to painting but with greater durability. The method entails melting dry plastic powder onto metal to create a textured, matte, or glossy finish. A textured powder-coating process can also be used to cover up existing surface flaws in an simple and effective manner.
  • Sand Blasting
    Sandblasting process is commonly used in projects that require a consistent matte texture. Sand, steel shots, metal pellets, or other abrasives are blasted into a substrate at high speeds in this process (also known as bead blasting). It produces a smooth, clean product texture, which is especially noticeable in soft metals.
  • Plating
    Plating process coats or changes the surface of a substrate with a thin layer of metal, such as nickel or zinc, using a chemical bath. Electroplating coats the substrate with an electric current, whereas electroless plating uses an autocatalytic approach where the substrate catalyzes the reaction. As a finishing technique, plating has a number of advantages, including improving a product’s durability, corrosion resistance, surface friction, and exterior appearance. Plating process, on the other hand, aren’t designed to smooth out surface flaws.
  • Blackening
    Blackening process applies a thin coating of black oxide over a product’s surface to generate a matte black finish with exceptional abrasion resistance. The product is placed into a sequence of tanks containing cleansers, caustics, and coolants during the high-temperature procedure.

Integrated Factory Resources

We are your one-stop manufacturing solution provider for customized products with the joint effort & support from our 120 partnership subcontractors mainly for the production of metals & plastics. We can expand much faster but the top management decide to keep GEMS a compact, dedicated and professional company, which allows our team to really focus and deliver on your projects without any excuse or compromise. We strive to be a long-term, reliable and trustworthy partner of our customers rather than just being a contractor, and look forward to growing the company with customers’ success.

Manufacturing Veteran Team

With the passing years, we are proud to build up a manufacturing veteran team with rich experience and full expertise to fulfill your specific demand. From mold making, injection molding, die casting, stamping and sheet metal, to 2nd processes like CNC machining, oil spraying, powder coating and chrome plating, and then assembling and packaging and related, we always have someone in house to be an expert to resolve the issues in different stages of product development. We also specialize in providing charger, cable and hub, plus other electronic accessories that support a complete set of product.

Strong Project Management

“Think global, act local” is the principle of our work. Time, quality and cost are the three key elements to be considered throughout the product development from concept design to mass production. A detailed plan with weekly conference call update is a critical gateway to ensure these three key elements are successfully implemented, also assuring that all parties are on the same page. Communication is the Secret to Success . Everyone works independently to take care his own job, but together we are a team to get things done and are your daily eyes and ears onsite in China.

Flexible Operation & Customization

We offer a wide variety of products, such as mold, component and assembly product, and certain value-added services. For logo or branding product, we have in house resources to complete a color mix that can perfectly match a brand’s unique colors in fast and cost-effective way. Understood the client needs production parts but having a hard time to find a vendor since the order quantity is as low as 1000 or lower. GEMS is well set up for low volume injection molding or die casting projects. Surely our team is also capable of building SPI Class 101 mold that is designed & made for 1 million cycles or more of producing the same high quality parts consistently.
