If your specification matches one of the grades held in Detmold, we supply from a single roll. Otherwise from ten rolls or sheets.

- How we work
From requirement to tested batch
TRIWES is the right partner when medium, temperature or approval narrow your choice and every repeat delivery has to meet the same values. So that this is documented and not just promised, every batch is checked against the agreed values. We issue the test report on request.
Three routes to your material, small series included
You tell us what the material has to do. We look for the grade that meets your specification, adjust it, or develop a new one. And if no elastomer meets your requirement, you hear that in the first conversation.
1
Stock material
2
Modification
If a grade nearly fits, we change hardness, colour or resistance. A sample is usually with you after a few weeks, depending on material and process.
3
New development
If the material does not exist, we develop it from the formulation up, and for moulded parts with our own tooling. Quantity, date and cost are fixed before anything is built.
At Steinbach AG, we manufacture seals in high volumes for demanding industries. For our material supply, we therefore rely on TRIWES as a reliable partner with technical expertise.

Six steps to delivery
The route is the same whether you need a roll from stock or a formulation that does not exist yet. Only the steps in the middle vary in length.
Applications1
Enquiry
You tell us where the part sits, what it has to withstand and how much you need. A drawing helps but is not required.
2
Technical conversation
On the phone you get the managing director, thirty years in the trade, not a sales desk. He names the grade that comes into question.
3
Formulation and costing
We define the compound or adapt an existing one. Values, price, quantity and date are fixed before anything is made.
4
Sample
The sample is usually with you after a few weeks, made in the same plant as the series that follows and against the same values.
5
Tested delivery
Every batch is checked against the agreed values: thickness measurement, visual inspection, laboratory values.
6
Delivery from stock
Once the series is running, your grade is held in Detmold, including for small call-offs and with no wait for the next batch.
Every batch is tested
You cannot tell by looking at a sheet whether it will hold. That is why every batch is checked at several points on its way to you: thickness at the line, visual inspection after unpacking, physical values in the laboratory, and finally the comparison against the signed delivery specification. Our managing director designed this testing chain himself and introduced it at the partner plants. We issue the test report on request.
What happens when your volume grows
The same plant
The series runs in the plant that already made the sample. Same line, same values.
Volume
Capacity does not hang on a single line. Quantities and dates are agreed individually for series and call-offs.
Repeat delivery
Once the series is running, we hold your grade in Detmold, including for small call-offs.
Development
Our partner plants have their own development departments. A new formulation needs no external laboratory.

Service life begins in the compound
How long an elastomer lasts in service depends largely on its formulation. That is why we develop and produce our compounds ourselves. It keeps the composition in our hands and lets us tune it to the load the part will carry. Rubber, fillers, cross-linking and ageing protection are the basis for the quality and resistance of our sheeting and moulded parts. That applies to all 22 grades, to stock material just as much as to series production. And if your application calls for particular properties, we adjust the formulation or develop a new compound.
Quality you can look up
CompanyISO 9001
Certified quality management at TRIWES.
Partner plants
ISO 9001 and ISO 14001 at the plants producing for you.
Test report
On request, against the signed specification.
Batch traceability
Every metre and every sheet documented, years later too.
What this becomes in the application
This way of working produces parts that hold where you cannot reach them again after installation: inside an analytical instrument, in the cooling circuit of a vehicle, in a building wall. Four applications, each with its job and the material that solves it.
Why it takes 22 grades
If you mix your own, you can grade finely. That is why eight families hold 22 grades, from 25 to 85 Shore A, and every one of them can be shifted further. With property values, resistances and the certifications that exist.
Tell us what your part has to withstand
Ten minutes on the phone will settle whether your part runs from stock or needs a compound of its own.
