Our Capabilities

Zinc Electroplating & Zinc Phosphating

Zinc Electroplating has been used for more than 100 years as a protective coating with electroplating as the most prevalent application method. Zinc electroplated coatings protect the base material against corrosion by forming a protective barrier and acting as a sacrificial anode if the zinc becomes damaged.

Zinc Phosphating is a crystalline conversion coating that is formed on a metal substrate by a chemical reaction between the plating bath and the metal substrate with no electricity needed for numerous applications from base coatings for paint and rubber molding to inexpensive rust preventive coatings.

Vibratory Deburring

Vibratory finishing is a type of mass finishing manufacturing process used to deburr, descale, burnish, clean, brighten parts for further processing. Burrs are most commonly created after manufacturing operations, such as stamping, machining, drilling, coining, turning, etc. These burrs are usually detrimental to the function of the part and must be reduced or removed.

In this batch-type automated operation, parts are deburred against each other in either a part-on part process or mixed with specially shaped pellets of media placed into the vibratory bowl. The vibratory bowl and all of its contents are then vibrated causing grinding contact between the surfaces the parts which yields the desired result.

Considerations for specifying vibratory deburring are dependant on the part application, required specifications, amount and type of burr,
required result, etc.
