Wear-resistant coatings of table rolls and CCM not only significantly increase a resource of their work, but also allow to avoid damage of products.
Metallurgy
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.
Cast iron retard rolls of the draw block are subject to wear by the passing wire. During operation, the roller was worn by a few millimeters.
HVOF-coatings of Plakart based on WC / Co and MoB / CoCr increase the resistance of the rollers to the effects of melt, wear and sticking. The estimated effect: coatings provide resistance to the rollers to several months without repolishing, and also prevent the formation of rolling marks.
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.
Corrosion under insulation, or underfilm corrosion, is one of the most dangerous threats to pipelines due to the complexity of detection and the speed of development.
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.
