Examples of repair
A few examples are given below of the repair works carried out by the Makai Kft. (Ltd.) in various special fields.
Hydraulics - Printing machines - Manufacturing of machines - Plastic industry - Vehicle industry
Protection of ancient monuments
Hydraulics:
The most frequent damages on the chromed surface of the piston rods are:
Seizings |
Strong abrasion |
Scratches |
Corrosion |
These defects are naturally found on the inner surface of the cylinder pipe as well
before repair | under repair |
after repair | |
Printing machines:
Typical damages are dents on the surfaces of the printing rollers caused by fallen objects (Allen key, screw, etc.), abrasion under-size on the edges of the cylinders, and ageing. An example is also given of the case when the bearing location in the sidewall of the machine gets worn – a situation rarely met, but still causing problems:
It has to be stressed that on-site repair on printers has the great advantage that cylinders do not have to be removed.
In the case of bearing locations in the sidewall of the machine, they can only be repaired after dismantling.
Manufacturing of machines:
We have worked on various industrial machines and equipment, and fixed the manufacturing defects and damages of large parts.
Typical faults included dimensional deviation between inner and outer diameters, and surface damages. We have prepared coatings as requested to alter the properties of a given surface, such as corrosion resistance, wear resistance or electric conductivity. On-site repair was highly beneficial in these cases as well, because transport cost and repair time could be saved.
Fitting inner bearing locations to size: |

Fixing the dimensional deviations of outer bearing locations: |
|
Repairing surface damages: |
|
Partial protection of surface against corrosion: |
|
Increasing the wear resistance of bores: |
Applying surface coating to increase electric conductivity: |
Plastic industry:
We have repaired damages on the surface of plastic processing dies, and have coated the surface of extruder screws to improve wear resistance and sliding properties.
Vehicle industry:
We have applied tampon galvanizing for the repair of vehicle parts on several occasions. Typical defects are wearing caused by rotating of bearings, wearing out the running surface of seals, wearing of high precision parts with fitting metal surfaces, and leaks due to ageing.
Wear caused by a bearing: |
|
Repair of ageing traces: |
|
Seizing caused by a seal: |
|
Protection of ancient monuments:
We have reconditioned metal ancient monuments as well.
