The production proces

PGN continuously invests in modern production environments. Computer-controlled machines and measuring equipment have become standard supports for people in the workplace. The result is a high-quality production process that has four phases: Pre-processing, casting, curing and post-processing.

First phase – Pre-treatment

For maximum adhesion between the coating to be applied and the – usually – metal surface of the roll or roller, a thorough pre-treatment is required. The old coating is removed, the roller is blasted and then an adhesive is applied.

Second phase – Casting

PGN now has 3 modern casting machines with large emissions of material. This allows PGN to handle several projects from 10 grams to about 30/35 Kg. In terms of hardness, PGN can vary between 20° Shore A and 60° Shore D.

Third phase – Curing

The curing is carried out in modern ovens. Because we are in possession of a small and a large cure oven, where we can drive with a lifting truck, we can process very small and very large and heavy products. It is a lengthy and accurate process in which the right cure time ultimately yields the desired quality.

Fourth phase – Post-processing

Finishing is performed on precision ground grinding and lathes. They can grind workpieces up to a length of 6,000 mm between the centers with a maximum diameter of 1100 mm and a weight of 5 tonnes without problems.

Measurements are carried out by computer-controlled measuring equipment and read by professionals. Very accurate tolerances of 0.01 mm are feasible, depending on the dimensions and overall condition of the metal cores. The application of a special profiling is possible on specification of the client or in combination with our advice. By using a CNC controlled grooving cutter / grinding unit, all common profile grooves and shapes can be milled or sharpened.
