Steel parts often require some form of heat treatment to increase their hardness and obtain maximum strength and durability. We need to carefully consider the heat treatment processing requirements to ensure the optimum performance properties can be achieved from the steel used to manufacture the machine blade.

Ensure proper handling of the knives always to avoid damages and assure a long lifetime.

For perfect knife performance, proper and timely maintenance is required. It is recommended to follow machine instructions from machine manufacturer for installing the knives and setting correct cutting gap.

An industrial knife is the heart and soul of the recycling process. It crushes and mills different types of waste – reusable raw materials (PET, plastics, copper, aluminium, rubber etc.) into granulate. Waste is never completely homogeneous. Normally it contains a variety of foreign bodies, which is why knives are usually under constant pressure. Consequently, chipping and breaking of the blades occurs quite often and is nothing uncommon.
