During the operation of the injection molding machine, the outer diameter and width of the screw cutting comb change as a result of wear, which reduces the performance of the machine and the quality of the products. Thus, the worn screw requires repair or replacement with a new one.
Chemicals and processing
Sprayed carbide coatings are used for the production of plugs and bearings capable of operating in conditions of dry friction. The use of steel plugs and bearings with thin carbide coatings is much more efficient than the use of parts sintered entirely from hard alloy.
The thickness of the sprayed babbit layer can be from 1.5 to 30 mm, the recommended thickness for the production of bearings - from 2 mm. Obviously, spraying a new babbit costs somewhat more than refilling the old one.
The assets of the company "Plakart" hundreds of sprayed bearings and several turnkey spraying systems. Contact our regional centers for babbit spraying.
Metallic chimneys and exhaust shafts of boiler and gas pumping plants are very difficult to protect against corrosion with lacquer or polymer compositions: temperature drops up to 600oC quickly burn protective coatings and leave the pipe unprotected against corrosion. Spraying aluminum-containing protective coating can solve the problem of protecting the chimney from corrosion for 15-20 years.
Wear-resistant electrical insulation coatings provide dielectric properties of products even in conditions of very strong abrasive and hydroabrasive wear.
The replacement of galvanic chrome plating of ball valves with high-speed flame spraying of nickel and cobalt-based alloys is the result of the development of the 1990s, which became the de facto standard in the production of modern valves and fittings in Europe and the USA.
Wear-resistant, corrosion-resistant heat-resistant internal coatings for gas flues. Alitizing by metallization of the internal surfaces of gas flues by flame spraying aluminum. Coatings withstand temperatures up to 800oC, work in vapors of sulfuric acid.
Rods of compressors are operated in the conditions of continuous production, sometimes in aggressive environments, therefore the working surfaces of the rods are nitrided or with the use of coatings.
Chemical resistant solid anti-corrosion coating for containers. Protection against chemical corrosion by spraying aluminum and zinc coatings. There are often situations when corrosion becomes a serious problem for equipment operation. Even small chemical impurities often cause rapid corrosion of the unprotected metal.
