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.
Machine manufacturing
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.
Plungers of the pumps which are pumping over chemically active environments are subject to influence of an erosion and corrosion. Production of plungers from special staly expensively also does not provide an acceptable resource.
Using high-speed flame spraying carbide coatings, we apply and restore worn chrome coatings of hydraulic rods.
The engineers of JSC "Plakart" designed and manufactured technological equipment for mounting the wheel in the rotator of the surfacing installation.
JSC Plakart performs repair of cylinders, hydraulic cylinder rods using high-speed carbide coating. The technology of repairing the rod involves removing the old chrome coating, applying a new layer by high-speed spraying and further grinding and polishing up to grade 12 of purity. Depending on customer needs, we can offer.
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.
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.
