Industrial knives and wear parts manufacturing specialist

Leading manufacturer of waste management and recycling machines and solution, Protechnika also specialises in supplying long life knife applications and wear parts, primarily for the recycling industry but also for other industries.


The cutting tool is a crucial factor in meeting the industry's productivity and quality demands. Sharp knives that stay sharp longer produce the high quality required for virgin material blending accuracy. And knives that stay sharp longer require less machine downtime for resharpening, increase cutting efficiency and reduce cost.

Our product range includes all types of machine knives, counter knives and screens as well as a wide range of accessories for industries such as clamping plates, screws and knife holders. For all our products, we follow your specifications and together select the most suitable steel, the right hardness and surface treatment for you.

At our Debowica based factory, we have the capability to develop and manufacture industrial knives, blades and wear parts to any specification, all manufactured to the finest tolerances from a variety of high-quality materials. Advanced Heat treatment processes are also available. All machining is done using state of the art CNC machines and grinders.
