Our Post Finishing Options

Polishing
Polishing is often used to deburr and remove machining marks and to make product surface looks smooth and even, it is manual work and preparation for further processes like painting or sandblasting etc.
We can also do high polishing to get transparent PMMA (acrylic) parts, often used for lightguides or lens.
Vapor polishing for PC products are also available, these parts are normally functional parts for testing, so very often used for prototypes.
Sand Blasting
Blasting is used to clean and deburr parts, it can be an independent process or a preparation for later surface finishes, such as anodizing or painting. It involves the controlled spraying of the abrasive media against the surface of the product.
At Marigold Rapid., we often use sand blasting, aqua blasting and bead blasting.


Painting
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. Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic. Painting can have a protective effect on parts, it is an effective method to protect metal from oxidation and corrosion.
Anodizing
Anodizing is widely used for electronic products made from aluminum, magnesium or titanium. Anodizing helps to resist corrosion, increase surface hardness, improve resistance to wear and dissipate heat.
At Marigold Rapid, we often apply Type II anodizing, which involves adding tints or dyes to parts for a variety of different colors. We can also do Type III anodizing, which we call “hard anodizing”, for parts that require harder surface than normal anodizing.


Powder Coating
Powder coating is a process of coating metal with a plastic finish applied in powder form and baked to a fluid state to bond it to the metal surface. Powder coating is mainly used for coating of metals, such ashousehold appliances, drum hardware, automobile, motorcycle, and bicycle parts.
At Marigold Rapid, the most popular colors to apply for powder coating is: black, silver, white, blue and red.
Brushing
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Brushing finish is produced by mechanically polishing or wearing away the outer surface of the metal. Brushing finish can be applied overall or selectively, in one or multiple directions.
At Marigold Rapid, we offer brushing surface finish mainly for CNC machined rapid prototyping parts or sheet metal prototypes.


Passivation
Passivation is a chemical treatment for stainless steel and other alloys that enhances the ability of the treated surfaces to resist corrosion. There are many benefits of passivated equipment and systems:
Passivation removes surface contamination.
Passivation increases corrosion resistance.
Laser Marking
Laser marking is a very cost-effective way to make logos or custom lettering to your designs and is often used for custom part tagging, it can be easily applied for prototypes and scale to production.
At Marigold Rapid, laser marking can be applied to the mold or directly to final parts, it ensures crisp, consistent information on each part or serialization.


Electroplating
Electroplating is the process of using electrodeposition to coat an object in a layer of metal(s). Engineers use controlled electrolysis to transfer the desired metal coating from an anode (a part containing the metal that will be used as the plating) to a cathode (the part to be plated).
At Marigold Rapid, electroplating is widely applied in numerous sectors for coating metal objects, the added metal has a desired property the original object lacks and is primarily used to improve corrosion resistance.
