Brass (H59/H62) has desirable properties for a number of applications, such as handles, automotive terminals and musical instruments.

It is low friction and has excellent electrical conductivity and its golden appearance make products looking excellent.

Copper (Cu-ETP) displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.

Titanium (Ti6AL-4V，TC4，TC5，Ti-6Al-4V-ELI) parts are frequently used in the aerospace, medical, military and marine industries.
Surgical equipment
Compressor blades
Airframe and space capsule components
Pressure vessels

Zinc alloys are promising biodegradable metals due to their desirable corrosion characteristics and good biocompatibility. Zinc alloys are used for a range of applications including cosmetic vehicle parts, complex part housings, and fuel system components. At Marigold, we normally use Zamak 3 for Zinc alloy. It exhibits similar machinability to copper but are less abrasive to tooling. Automotive part shells and small electric motor casings are typical applications for this type of zinc.

Plastics are also very popular option for CNC machining because of its wide choices, relatively lower price, and significantly faster machining time needed. We provide all common plastics for CNC machining services.

Sand blasting results in parts with an identical surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments such as anodizing.

Sandblasting can be applied for various of materials of rapid prototypes, like ABS, Aluminum, Brass, Stainless Steel, Steel etc.

Anodizing is one of the most widely used finishing for rapid prototyping parts, it improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. It is often applied in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

At Marigold Rapid, we can offer different anodizing colors like clear, black, red, blue, gold, grey.

Painting is one of the most widely used surface treatment in industrial products or our daily life. With painting we can achieve different kinds of finishes, such as matt painting, glossy painting, textured painting, soft touch painting, and in theory any color is possible upon request.

At Marigold Rapid, we use both Pantone code and RAL code for color reference. And quite often customers also provide golden samples to us for our reference during production.

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. 

At Marigold  Rapid, the most common colors we offer for powder coating is black and white, but we can basically offer any RAL or Pantone code colors upon request, and also glossy or matt finishes are available.

Electroplating is majorly applied to modify the surface features of an object (e.g corrosion protection, lubricity, abrasion). Some of the other common applications of electroplating involve:
· Improving wear resistance.
· Improving the thickness of the metal surface.
· Enhancing the electrical conductivity like plating a copper layer on an electrical component.
· Minimizing Friction
· Improving surface uniformity.
