Para Tech Coating, Inc. is ready to meet your production coating needs at one of our fully equipped and staffed coating centers. We operate as an extension of your manufacturing team, committed to your business success and partnering in problem solving, training, quality assurance, and on-time production scheduling.

PTC provides application engineering support for every project, with engineering runs typically completed according to customer’s schedule. Production is accomplished using large automated static coating systems for fixtured parts, and tumble-coat deposition equipment for high quantity, uniform parts that lend themselves to tumble coating.

Areas to remain uncoated are precisely masked, and parts are placed in fixtures and positioned in the coating chamber. When the deposition cycle is complete, coated parts are unmasked and inspected in accordance with quality control standards. Small components can often be treated by tumble coating, which minimizes handling and provides complete Parylene coverage.

Parts such as printed circuit boards, medical components or other assemblies that require selective Parylene coverage must be masked before coating to restrict exposure to the polymerizing gas in the vacuum chamber. Parts are then placed in fixtures that hold them in place during the coating cycle and provide the optimum combination of chamber loading and exposure to the monomer gas.

Unfixtured, high quantity and uniform components that do not require masking can be placed in a rotating cylinder sealed within the coating system vacuum chamber. The components are kept in motion throughout the deposition cycle, allowing the polymerizing gas to reach and coat all surfaces evenly. Multiple component types can be treated simultaneously in this manner without sorting or isolation.
