What is the process of hard chrome plating?

Image
  Hard chrome plating   is a process in which a layer of chromium is applied to a surface to improve corrosion and abrasion resistance, reduce friction, and extend the life of parts used in extreme wear conditions. Hard chrome plating demonstrates excellent hardness and lubricity, and is the premier engineering choice to reduce friction, minimize wear and prevent galling. These characteristics are applicable for critical engineering applications, including: machine tool cutting surfaces, cylinder bores, strut rods, crankshafts and  hydraulic shafts . Hard chrome is also applied to molds because of its low surface energy and resultant release properties. Chem Processing can hard chrome plate steel, aluminum, or copper materials, as well as many exotic alloys. Hydraulic cylinder rods , bearing fits and seal areas frequently get damaged and worn from heavy use. When no longer functional, a part can be hard chrome plated and polished or ground back to OEM Spec. This process c...

WHAT IS DEAD ROLLER SHAFT AND LIVE ROLLER SHAFT

 live shaft and dead shaft rollers can be used for the same application and the choice is a function of the machine’s mounting system. But at other times, the differences between the two designs mandate a clear choice.  DEAD  ROLLER  SHAFT S: Roller design is bearings pressed into the ends of a hollow tube (the roller body) with a long shaft running through the bearings and extending out the ends of the rollers. The roller is considered to be a “dead shaft” because the shaft does not turn. The shaft is fixed to the machine or frames mounting system by clamping or bolting and the roller body turns about the shaft via the bearings. Roller shells can be steel, aluminum, or carbon fiber and many times are thin-walled, making them ideal for light load and high-speed web applications. Commonly used as idler rollers due to light-weight, low-turning inertia and the availability of low friction bearings which reduce roller drag. Roller rods  must be web or nip driven bec...

What is ST52 Steel Plate

The ST 52 belongs to a standard structural steel grade. A  St 52 Steel Plate   is designed with a superior chemical composition of carbon, silicon, manganese, phosphorous, and sulfur. The content embedded in these plates gives them enhanced resistance to corrosive and oxidative media. The St52 Plate is designed for thickness above 6mm and more. These plates have enhanced resistance to pitting and crevice corrosion. They provide good stability and support to different applications. St52-3 Plate is a low manganese carbon grade that doesn’tputs pressure on subsequent modules. These robust plates can be easily welded in place following standard procedures. The versatile St52 3 Steel showcase slightly lower strength and tolerance compared to an St52 plate. These lightweight components comply with different national and international standards. The St52 Steel Sheetis produced in thicknesses below 6mm and above 0.5mm. These sheets don’t provide stability and add an aesthetical appeal...
