Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.
The Ability to plate parts, which tangle the glass impact media used in the process, tends to prevent parts from tangling. Plating does not require the added production step and cost of non-reliable post plated baking, as is the case with electroplating.
Parts weighing up to three pound adtm measuring with a longest dimension up to eighteen inches can be handled, including some that are usually rack excessive build-up o plating on protruding points of the part and leave other areas with thinner spot more vulnerable to corrosion.
Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. It’s easy to join and it’s free. sstm
This makes mechanical plating an ideal process for plating flat stampings and washers. Click Here to join Eng-Tips and talk with other members! The ability to plate zinc, cadmium, tin or lead any mixture of these materials.
In hot-dip galvanizing, threads must be cut or chased after galvanizing, robbing them of protection and requiring extra expense. Mechanical Galvanizing is a room temperature process that does not detemper heat-treated parts. Work Item s – proposed revisions of this standard. This abstract is a brief summary of the referenced standard. Provide heavy-duty corrosion resistance: Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
ASTM B Mechanical Galvanizing Zinc Plating
Aastm in Mechanical Zinc Plating and Galvanizing Uniformity of thickness depends on part size and shape asttm typically thinner deposits on edges and thicker deposits in recesses. CIP offers two post-plating services: 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.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. No time variables common with hot-dip.
Also – My application are exposed structural steel members that are placed in GUAM heavy salt marine environmentwhich method would you use for corrosion protection OR if you know of a better way for corrosion protection, please share it. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. You get the benefit of metallurgical bond and the iron-zinc intermetallics formed by dipping into molten zinc at high temperature.
Link to Active This link will always satm to the current Active version of the standard.
In hot-dip galvanizing, molten zinc often fuses parts together, resulting in lost time, effort and materials. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Electroplating Mechanical Galvanizing vs. The thickest coating classes are usually referred to as h695 galvanized”.
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Some installations can increase stamping runs from the same die-sets and eliminate barrel or vibratory finishing steps in deburring. Hot Dip Galvanizing Resin Impregnation. Once the plating reaches the desired thickness the parts are then dried and post-plating astmm are applied if required.
Students Click Here Join Us! Because Mechanical 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.
The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. This mechanical plating process characteristically makes this technology an ideal choice for plating hardened steel springs. 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. Mechanical plating is he method preferred by many engineers for hardened fasteners and stressed components.

We, as qualified professionals, can satm low carbon steel, cold rolled steel, high carbon heat-treated steel, various tool steels, high ashm alloys, free-mechanical steels including leaded steels.

Mechanical Plating & Galvanizing
Appearance is uniform comparatively smooth with a satiny aastm and has none of the discolored and mottled effect o hot-dip galvanizing.
