Custom manufacturing
Knives and ripper teeth made to drawing, sample or existing part
Most recycling knives and ripper teeth are not stock items but order-specific custom builds. We manufacture to your drawing, to a sample or from a worn original part – including a material and hardness recommendation.
What does "made to drawing" mean? In manufacturing to drawing, an industrial knife, ripper tooth or wear part is produced exactly to the dimensions, hole patterns and material requirements specified by the customer – as opposed to catalogue goods with fixed dimensions. Where no drawing exists, an existing part or photo is often enough as a template for an accurate reproduction.
Process
How a custom build works
Enquiry & documents
You send a drawing, sample, photo or existing part along with any available details on dimensions, material and quantity.
Technical clarification
We review geometry, load and operating conditions and clarify any open points directly with you.
Material & calculation
Recommendation on material grade and heat treatment, calculation based on batch size and target price.
Manufacturing & delivery
Manufacturing, heat treatment and inspection – on request included in a framework agreement.
Documents
These details speed up the calculation
The more complete the documents, the more precise the material and price statement. The following helps most:
- Drawing with dimensions, tolerances and hole pattern (PDF, DXF/DWG or sketch)
- Alternatively: a sample, existing part or meaningful photo with dimensions
- Material and heat treatment, if already known or desired
- Quantity per order and expected annual demand
- Desired production batch size and target price, if available
- Desired delivery date and repeat requirement
Why this matters
Dimensions, material and quantity directly affect price and service life
| Detail | Effect on the result |
|---|---|
| Dimensions & drawing | Fit accuracy, installability, less rework |
| Material grade | Service life, impact toughness, abrasion resistance |
| Heat treatment | Hardness, wear resistance, tendency to chipping |
| Annual volume | Option for framework pricing and quantity scaling |
| Production batch size | Unit cost, set-up effort, delivery time |
| Target price | Balancing material choice vs. economy |
| Repeat requirement | Suitability for a call-off agreement & stocking strategy |
Good to know
No drawing available? No problem.
Reproduction from a sample
A worn original part provides geometry and hole pattern – we technically reconcile the worn edges.
Reproduction from a photo
A dimensioned photo is enough for a first assessment; for series production we recommend a drawing.
Material change possible
Even with a reproduction, we check whether a different material improves service life economically.
