Techmetals’ president Phil Brockman is often the last electroplater that some customers visit on their search for solutions to persistent finishing issues or to plate unique parts. But it’s easy to see why most major aerospace, medical, defense, oil/gas, mold shops, and automotive manufacturers end up at Techmetals’ expansive facilities in Dayton, Ohio.

Progress in Replacing Decorative Electroplating Chrome Coatings on Plastics with Physical Vapor Deposition Coatings
Decorative electroplated chrome coatings on plastics have been produced for decades. For environmental reasons, there has been a shift away from hexavalent chrome (Cr6) to trivalent chrome (Cr3) with increased investments towards elemental chrome PVD coatings to maintain the true chrome appearance.
This overview takes a look at vacuum deposition technologies as processes that may be used to create coatings that can be substituted for or enhances the properties of electroplated coatings. Initially, this work discusses trends in metal finishing and environmental regulation.

MVRE is underutilized in the treatment of industrial wastewaters that are typical of metal fabricating and finishing industries. Increasing energy costs, rapidly decreasing freshwater resources, and growing sensitivity towards the environmental impact of industrial management practices are the driving forces in the development of more sustainable technology.

Ionic liquids have also been considered for parts cleaning applications because of their negligible vapor pressure, high thermal and electrochemical stability, and low melting points of less than 100°C.
To help optimize its solvent vapor degreasing process while minimizing solvent exposure in the workplace and the environment, Miba Bearings US uses Dowper SVG double-stabilized perchloroethylene in the Safecare system from Safechem North America LLC, a subsidiary of Dow Chemical Co.
In the finishing world, there are four common precision cleaning processes: hydrocarbon, aqueous, semi-aqueous, and vapor degreasing. Each has its strengths and disadvantages, but one of the biggest problems with aqueous and semi-aqueous cleaning is the quantity of electricity they take.
I am interested in coating PVC foam boards with paint. I heard that vacuum coating is a process that will work for this application. Can you direct me to a company that can either supply the equipment to vacuum coat, or provide the service to vacuum coat?
For more than forty years, academic and industrial researchers from all over the world have taken a strong interest in alternative processes for hard chromium plating using hexavalent ions. The benefits of substitute processes are obvious, as the toxic and carcinogenic aspects of hexavalent chromium are well known.
I am interested in coating PVC foam boards with paint. I heard that vacuum coating is a process that will work for this application. Can you direct me to a company that can either supply the equipment to vacuum coat, or provide the service to vacuum coat? Are you aware of any other methods that could be used to coat these boards?
