Eliminate retapping of units: Some installations can increase stamping runs from the same die-sets and eliminate barrel or vibratory finishing steps in deburring. The ability to plate flat parts: Surface protection guide for steelwork exposed to atmospheric environments ht tp: In hot-dip galvanizing, molten zinc often fuses parts together, resulting in lost time, effort and materials.

Neither will be great for long-term marine exposure, I would suggest a high-build organic coating system probably with a zinc-based primer or thermal spray base layer. Specializing in Mechanical Zinc Plating and Galvanizing Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses.

Appearance is uniform comparatively smooth with a satiny texture and has none of the discolored and mottled effect o hot-dip galvanizing.

Mechanical Plating & Galvanizing

Hot dip galvanising is generally more durable and sturdy than mechanically applied zinc layers. Batch to batch conformity: Mechanical plated arts can be given post plate treatment of dichromate dye for color-coding and phosphate for improved paint adhesion and waxing.

Thickness depends only on asfm amount of zinc powder. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.

Historical Version s – view previous versions of standard. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Download Now Defense manufacturing is all about project manufacturing and project accounting. We, as qualified professionals, can plate low carbon steel, cold rolled steel, high carbon heat-treated steel, various tool steels, high strength alloys, free-mechanical steels including leaded steels.

The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Sacrificial metal coating is applied with coverage to all surfaces of the part to the corners recesses, threaded areas as well as to the flat, more exposed regions.

For equivalent thickness, mechanical galvanized is equal or superior to conventional galvanizing methods.

Nonmagnetic Coatings on Magnetic Basis Metals. CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. Because B95 Galvanizing is an extension of mechanical plating technology; it does not produce hydrogen embrittlement and does not require lengthy non-reliable post-plate baking cycles. CIP offers two post-plating services: Hot Dip Galvanizing Resin Impregnation.

Mechanical Galvanizing does not fill valleys of threaded fasteners and their parts mate quickly and easily. All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright b6955. Mechanical Galvanizing is a room temperature process that does not detemper heat-treated parts.

The inch-pound equivalents of SI units are given for informational purposes. Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.
