Manufacturing Process of the Die Ring
After drilling and tapping bolt holes, milling keyways, turning up the basic shape of the die blank, cleaning, drying, vacuum hardening, tempering and finally finishing to the fitting sizes, the entire production of the die has gone through nearly 40,000 separate machining, processing, and handling operations.
We meticulously follow these instructions and manufacture the dies with accuracy and repeatability on the basis of an automated production process.
The heat treatment process is of utmost importance as it guarantees the product uniformity.
Selected high-quality steels with fine grain structures give high strength and durability.
Washing and Polishing
Oil, moisture and machining burrs are removed from the die surface prior to the heat treatment.
Air is removed to create an inert environment. The die is heated in stages controlled by a microprocessor up to a temperature of 1,010 °C, and the steel becomes a hard molecular structure as a result of this process.
In the final stage, and as the die is machined to fit the pellet mill perfectly, a check is conducted to ensure that the product conforms to the original specifications.
The dies are then packedand prepared for dispatch to all parts of the world.
Roll shells operate under extremely harsh conditions. Therefore, it is vital that the dimensions are
