André J. Wießmann brings over 30 years in elastomer and sealing technology, including his time at Metzeler Technical Rubber and Cooper Standard. As managing director of TRIWES he personally assesses which material suits your application and when a compound of its own is needed. Small series with documented quality are part of that for him. When you call, you discuss your requirements with him directly.

- About us
TRIWES quality holds. Batch after batch.
TRIWES grew out of one ambition: to be an elastomer supplier whose quality is the same on every repeat delivery. That is why the materials are made to our own formulations, the values are fixed before the first delivery, and every batch is checked against them. And why you speak to a person who understands your job technically.
:quality(75) "Unternehmen Erfahrung")
Experience you reach directly
Established suppliers, clear responsibility
We work with established manufacturing partners in Germany, Italy and Thailand, all qualified by us. Which of them takes your order depends on the process required. Specification, testing and release are TRIWES's responsibility.
Dependable quality in every batch
The testing procedures introduced by TRIWES make sure every batch meets the agreed specification. That covers requirements for hardness, temperature range and media resistance as well as the necessary approvals. These requirements apply from the first sample to every later repeat delivery. Your point of contact remains TRIWES.
:quality(75) "Teambild 4 Mitarbeiter - Triwes")
A small team, direct contact
Behind TRIWES stand four people, working flexibly and entirely from home. For you that means named contacts in a team you can keep track of. Our one fixed location is the warehouse in Detmold, from which your goods are shipped. This way of working needs no office building of its own. And when we are on the road, we drive electric.

Responsibility starts with material input
Making elastomers takes raw materials and energy. That is why we look at the planning stage for ways to avoid unnecessary material consumption. Depending on the component, producing a moulded part instead of cutting from sheet can noticeably reduce material input. One of our customers switched over to that process entirely and saved considerable cost as a result. We look for opportunities like that together with you.
Which documents do you need?
Certificates, information for your supplier questionnaire or a technical question. The answer comes from the managing director.
