Northern Industrial Plating can satisfy your needs by applying the following finishes:

Hard Chrome Zinc Plating Electroless nickel plating Decorative plating

Hard Chrome
Industrial Hard Chrome plating is applied on bearing surfaces, seal areas, cylinder shafts, pins, chipper knives, seal rings and many other different items. It is also used to build up, repair and increase the life of the part. Most pieces are polished after plating, however some parts need to be ground. We are capable of doing both procedures in our facility.

Hard Chrome provides a hardness and a resistance to corrosion and wear. Hard chrome is ideal for parts that are subject to friction, corrosion and high temperatures. Hard Chrome is used on tools, dies, shafts, machine parts and much more.

Zinc Plating
Zinc plating, zinc chromate and dichromate plating are a valuable tools when used to combat the corrosion of steel. The zinc corrodes before the steel does, sacrificing itself for the benefit of the steel. Chromate conversion coatings are available to enhance the zinc coating and to provide a choice of color-coding.

• zinc chromate (silver)
• zinc dichromate (gold)
• black plating.

The zinc plating of metals can be divided into two groups. These groups are:

• Barrel
• Rack

Barrel Plating is used when the plating is done inside of a perforated barrel, and the barrel is rotated to even the plating. It is mainly used in the plating of small diverse objects, devoid of sharp and long edges that tend to plate badly.

Rack Plating is used for plating objects that are too heavy, too large, or too complicated to barrel plate. These can vary from small things such as keyholes, to large rollers. Most rack plating set-ups, are made up of copper rods, that conduct electricity very well, and are very durable. The objects are clipped to this copper rack and then put in to the electrolyte solution. The placement of the copper rack in the solution is crucial because if the rack is placed incorrectly, the plating may be lop-sided and uneven.

Electroless Nickel
Electroless Nickel is an advanced auto-catalytic plating process that does not use electricity to plate nickel on a part. Instead, parts are placed in a solution of nickel, phosphorus, and a few other items such as boron, where a chemical reaction occurs at the surface of the part to create a nickel-alloy deposit. The deposit, which looks like polished stainless steel, has a hardness of 48-52 on the Rockwell C Scale. Electroless nickel can be plated to most surfaces (copper, brass, steel, stainless steel and aluminum), including non-conductors.

Decorative Plating
Brass: We do decorative brass on many different objects from bathtub feet to doorknobs. Brass plating gives a gold finish similar to gold plating and a much more reasonable price. However, due to the oxidization of the metal, this coating must be clear coated after plating to protect if from the elements.

Nickel: We provide nickel plating for your decorative and protective nickel needs, with plating on steel, copper, and brass. We can nickel plate everything from stained glass, spurs and load cells.

Chrome: Chromium plating prevents rust in smaller parts in places like tight corners. It is applied to so many different types of articles that the brilliant, bluish appearance of the metal is familiar to everyone. The deposit does not tarnish and requires only occasional washing with soap and water or wiping with a soft cloth to remove any accumulation of dust and dirt from the surface. We are experienced in the decorative chrome process and we do it well.
