REGENERATION OF MACHINE PARTS
The reconditioning of machine parts is often a complex process involving many technical issues. Its aim is to restore 100% functionality to the new part, at a lower price than buying a new part. Thanks to advanced surface engineering processes, it is often possible to extend the service life of a remanufactured part. Reconditioning mainly concerns: conveying, mixing and dosing systems for highly abrasive media, shafts and rotating equipment, ball valves, hydraulic cylinders, grinding rollers, grinding knives and hammers, shredder elements, screw feeders, moulds, screens and others. The reconditioning process consists of several essential steps.

LABORATORY ANALYSIS OF WEAR PROCESSES
When the wear process is caused by the same media over and over again, it is possible to simulate the working process in our laboratory. We perform tests on samples of selected coating materials, reducing the costs and risks of introducing new materials and technologies and estimating the cost-effectiveness of a solution.
01
CLEANING THE PART
It is used to remove dirt, grease, lubricants and surface rust from the detail.
02
ANALYSIS OF WEAR AREAS
Recognising the wear process, identifying possibilities to reduce it.
03
SELECTION OF REPAIR TECHNOLOGY
Among the repair technologies, the most common are: thermal spraying of regeneration layers, surfacing or cutting off and welding a new part of the component. Previously, any remaining old coatings are removed from the workpiece.
04
APPLICATION OF WEAR-RESISTANT LAYERS
Once the wear process has been accurately identified, we can apply coatings with specific properties to ensure longer component life. Depending on the operating conditions and other expectations, these can be thermal sprayed, hardfaced or plastic-coated.
05
COLLECTING OPERATIONAL EXPERIENCE
After the nominal service life of the component, we are able to estimate the condition and degree of wear of the remanufactured part and determine the financial and technical benefit for the customer. It often happens that by increasing the service life of one area of the part – the need for service downtime arises for another reason – e.g. a second friction pair component or wear of another area of the part. We then select a coating system that provides the maximum benefit based on our experience.
