Anodizing
Anodizing creates a protective oxide layer on some metal surfaces. It increases corrosion resistance, surface hardness, and wear resistance while providing a unique look to the parts.
Our standard service is type II anodizing, which can be color-customized. Type III anodizing is also available for surfaces that need to be extra hard.
How it is done: The part is cleaned to remove oils and contaminants, then submerged in a sulfuric acid bath. An electric current is applied to form a porous oxide layer. If coloring is required, electrolytic or dip coloring is used. Then, the part is sealed in boiling deionized water and blow-dried.
Applications: Aluminum, magnesium, and titanium accept anodizing the best.

Painting
A good paint job is one of the best ways to make your product stand out. Many colors and surfaces can be achieved, such as matte, flat, gloss, and semi-gloss.
Procision uses 6-axis painting robots for fast turnaround and consistent results.
How it works: Painting is done in climate-controlled spray rooms. The part is first cleaned and prepared, and then PPG automotive polyurethane paints are used to replicate your desired color, tint, or hue. Parts are dried in infrared ovens for the best results, and then sent to our quality inspection department for color matching tests.
Applications: Most materials can be painted, including plastics, metals, and composites. However, some specialized resins like PTFE are difficult to paint without extensive preparation.

Pad Printing
Pad printing is one of the best methods for adding logos, labels, and detailed graphics to a flat or slightly curved surface. It is fast and inexpensive, but is limited to one color at a time.
How it works: A rubber pad picks up ink from an etched printing plate and transfers it onto the part’s surface. The stamp’s flexibility allows it to conform to curved shapes.
Applications: Pad printing is compatible with many plastics, metals, and coated surfaces. In addition to branding, it can be used to mark part numbers, serial codes, and other identifying information.
Procision
Laser Etching
Laser etching is an even more durable marking technique that can be applied to flat surfaces. It doesn’t add color, but is more precise and provides finer resolution and detail than other methods.
How it works: A low-power laser is used to burn away a minute amount of surface material in a controlled pattern, revealing the base material in contrast to the surrounding area.
Applications: This process can be used to add company logos and graphics, serial numbers, QR codes, manufacturing data, and other information. Etched surfaces won’t fade over time and can’t be accidentally wiped off, so they’re useful for products that might be exposed to adverse environments.
Sanding And Polishing
Sanding and polishing are applied as preparation for other services, to remove burrs, or to achieve smooth surface effects.
How it works: Sanding relies on abrasives of varying grits, while polishing uses fine powder, rouge or paste. Depending on the application, sanding and polishing is performed by hand or with rotary buffing tools.
Applications: It’s ideal for plastics, metals, and composite materials where surface smoothness impacts function or appearance.
Procision
Vapor Polishing
Vapor polishing is a specialized finishing process for making optically clear plastic parts.
How it works: First, the part is sanded, usually between 1000 and 1500 grit. Then, Weldon 4 solvent is heated to the boiling point in a controlled environment. The resulting vapors are sprayed onto the workpiece, causing it to melt and flow at the microscopic level which evens out any minor imperfections.
Applications: It is used mainly to create clear polycarbonate (PC) parts. Other plastics like PMMA also accept this finishing well, though it typically has good transparency right after molding.
Procision
Blasting
Blasting treatments are used to remove minor surface imperfections, clean contaminants, and create specific surface textures.
How it works: High-pressure guns are used to spray abrasive media onto the workpiece. Sand, glass beads, walnut shells, garnet, or even pure water can be used. The media impacts with the workpiece, removing rust, contaminants, and small marks while imparting unique and subtle effects to the surface.
Applications: Most metal and some kinds of hard engineering plastics can be media blasted. In virtually all cases, the result is a uniform matte or non-reflective surface without any noticeable orientation or pattern.
Depending on the abrasive media and technique utilized, it can also improve adhesion for the later application of paint or primer.
