Stainless steel is resistant to rust and staining, making it perfect for kitchen appliances and medical equipment. Its strength and aesthetic appeal also make it a popular choice for architectural designs and automotive parts.

Steel is a strong and versatile material, widely used in construction and manufacturing. Its high tensile strength makes it suitable for structural components, while various Subtypes enhance its properties for specialized applications, like tools and machinery.

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.

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.

POM is strong and has a low-friction surface, making it perfect for precision parts like gears and bearings where things need to fit just right and work smoothly.

PMMA (acrylic) is clear, weather-resistant, and won't fade. Ideal for outdoor displays, signage, and lighting, it holds up well in the elements.

Polycarbonate is super durable and clear, with amazing impact resistance. Commonly found in bulletproof glass and safety gear, it can take a hit without cracking.

PEEK is strong and can handle high temperatures without losing its strength. Found in high-performance industries like aerospace and medical implants, it's built for extreme conditions.

Polypropylene is tough, chemical-resistant, and handles higher temps. It's commonly found in car parts, containers, and packaging, especially where exposure to heat or chemicals is common.

PPSU (Polyphenylsulfone) is a high - performance engineering plastic. It has excellent heat resistance (stable at 180°C long - term), good chemical resistance, high mechanical strength, and superior electrical insulation. Biocompatible and sterilization - resistant, it’s widely used in medical, aerospace, chemical, food, and electronics fields.

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. 

Polishing process can be applied for different metals such as Aluminum, Brass, Stainless Steel, Steel.

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.

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.
