Zinc plating is a sacrificial coating used to protect the integrity of fasteners, stampings, or steel parts. Zinc is the most common and economical type of plating. It provides a continuous coating over the entire part and increase the corrosion resistance. In addition, zinc plating prolongs the life of the base metal, improves the aesthetic value and can be used for identification purposes, when combined with colored chromates.
Parts can be plated to any desired thickness. The degree of thickness will offer different levels of protection.
We are able to provide a parts baking service, which allows for the relief of hydrogen embrittlement.
We have a “continuous feed belt” bake oven and also a “batch” bake oven to take care of customer needs where hydrogen embrittlement is a concern.

Zinc Rack & Barrel Electroplating
WHAT IS ZINC ELECTROPLATING?
Zinc electroplating is a soft, ductile, functional, and sometimes decorative corrosion-resistant finish that protects steel products from red corrosion. Unlike most other commonly used metal finishes, zinc has the ability to protect the substrate even if it has been compromised. The protection is accomplished by a galvanic reaction between the steel substrate and zinc coating. Because steel is more noble than zinc the zinc sacrifices itself to the steel and corrodes before the base metal thereby protecting the steel. The zinc can also be further protected by the addition of a chromate film over the zinc, and even further more by the addition of
a topcoat over the chromate film.
Rack Plating is most often the choice for large, delicate of complex parts. Prior to plating, the parts are evaluated by Plateco’s production engineer so as to provide the most efficient fixturing to the plating rack. This is also a must to ensure optimum plating result.
With the parts fixed to the racks, and thus not subject to damage, the rack plating process provides high-quality plating result. The rack plating process allows for more strict control and can evenly plate even complex parts with intricate contours.
Barrel electro plating is an economical bulk process of zinc plating fasteners, and small to mid-size stampings. The part are processes through a series of alkaline cleaners, and acid pickle to remove oil, scale, and light rust prior to applying the zinc coating. Zinc thickness can range from .0001″ to .001″ with most products requiring. .0002″ to .0003″ of zinc. After the zinc coating is applied, the process is capable of applying a wide variety of top coats, sealers, or torque modifiers. Plateco has a large barrel line that allows us to plate larger stampings than most other barrel processes, allowing Plateco to provide competitive pricing of fasteners, and large sized stampings.
All first run parts are routed through Plateco’s Engineering Department. The purchase order/print is reviewed for plating, and packaging requirements. The parts are carefully measured for weight, area, and volume. Rack plated part are evaluated for the most effective process to fixture the parts to the plating rack. Detailed racking instructions are written, and many time photographs are added to the work instructions to allow machine personnel to quickly process customer parts. This pre-planning allows Plateco to prevent errors in processing, and allow for efficient processing of parts.
