Renovation of screws and barrels

Renovation of screws for injection molding machines, extruders and others with special carbide material.

We use modern equipment for screw surface treatment with PTA surfacing technology with hardness up to 64HRc.

WE RENOVATE DIAMETERS OF 35 MM – 300 MM UP TO A LENGTH OF UP TO 8,000 MM

PTA welding technology used by us

- eliminates the formation of cracks in the screw overlay layer

- ensures the highest quality and service life of the screw working surfaces

Particularly suitable for extreme conditions (processing of plastics containing abrasive particles)

We also perform screw nitriding.

OUR STANDARD DELIVERY DATES

1 – 2 WEEKS OF SCREW RENOVATION

3 – 4 WEEKS RENOVATION OF THE COMPLETE SCREW AND BARREL ASSEMBLY (including nitriding)

Products Renovation of screws and barrels

Renovation of barrels - honing and nitriding

Renovation of injection molding barrels, extruders by honing. Honing hydraulic cylinders and others.

Renovation of screws STELLITE 1

Hardness of welded layer 55 - 58 HRc Designed for quick repairs. The expected service life of the screw after renovation is limited. We recommend simultaneously ordering a new screw in a higher quality.

Renovation of screws STELLITE 12

Hardness of welded layer 43 - 45 HRc Designed for quick repairs. The expected service life of the screw after renovation is limited. We recommend simultaneously ordering a new screw in a higher quality.

Renovation of screws Colmonoy 56

Hardness of welded layer 52-57 HRc The most used weld suitable for most applications such as film blowing, profile production, etc.

Renovation of screws C06

Hardness of welded layer 58 - 63 HRc. Weld-on suitable for demanding applications such as recycling, rubber processing, etc.

Renovation of screws Colmonoy 83

Hardness of welded layer approx. 60 HRc + 33 Wc (hardness 2400Hv) Weld-on for very demanding applications such as abrasive rubber processing, recycling and more.
