What are the types and benefits of Knife Heat Treatment?
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.

We appreciate our customers’ feedbacks!
Here’s what some of our customers say about our work.
When does my knife need to be sharpened?
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.
Having problems with lifetime, throughput or cracking?
Ask for DURALIFE V+ KNIVES – the next generation of granulator knives
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.
Key benefits of RAVNE KNIVES
Knife manufacturing technology at SIJ Ravne Systems has evolved tremendously over the years to meet the increasing demand for cost-effective top-quality knives for specific industrial applications (metal industry, recycling, wood and wood processing industry and also paper and tire industry).
