Made to drawing or available from stock – you decide what fits your demand
Many knives, ripper teeth and wear parts are order-specific custom builds: matched to machine, material, hardness and target price. At the same time, we keep frequently needed standard sizes in stock for short-notice delivery – with no compromise on material quality.
- Manufacturing to drawing, sample or existing part
- In-stock standard dimensions for immediate use
- Material and hardness recommendations from experienced steel and application engineers
How we calculate
The more precise the details, the better the price, batch size and stocking strategy
We don't work from a list of fixed unit prices – every part is calculated technically and commercially. The following details help us find the most economical result:
DimensionsMeasurements & geometry, ideally with a drawing
MaterialMaterial grade & heat treatment
VolumeAnnual demand & repeat requirement
StrategyBatch size, target price & stocking strategy
For regularly required articles, annual agreements, framework prices and call-off models are available – reducing procurement effort and securing availability.

The right steel determines service life and economy
Wear parts in recycling plants face impact, abrasion and changing material hardness. We select tool steels and heat treatment specifically by load case – not by catalogue default.
Tool steels
Cold-work and hot-work steels as well as HSS grades, depending on impact, pressure and abrasion load.
Heat treatment
Hardening, tempering, case hardening – matched to toughness and wear resistance.
Special designs
Carbide-tipped and wear-optimised variants for extreme service-life requirements.
Frequently asked
Answered briefly
Are there list prices?
No. Dimensions, material, hardness, quantity and target price drive the calculation – there are no flat unit prices for technical wear parts.
Can you manufacture from a sample?
Yes. An existing part or photo is often enough as a starting point; a dimensioned drawing adds further accuracy.
From what quantity is a framework price worthwhile?
With recurring demand – often from just a few call-offs per year. We review it individually.
