Elastomer diaphragms are vibration-resistant seals with a demanding requirement profile. They enable dynamic sealing tasks that cannot be realized with conventional materials such as rubber seals or O-rings.
Great attention is paid to resistance to changing pressures, temperatures and media while maintaining unrestricted mobility and durability.
Elastomere GmbH is one of the pioneers in this field and has a wealth of experience when it comes to customized solutions for complex diaphragm tasks. Its expertise covers not only the shaping of the diaphragm, but also the production of fabric-reinforced base fabrics.

GuK GmbH is your specialist consultant in the field of rubber and plastics technology. We see ourselves as a solution provider and competent partner for our customers, who benefit from the comprehensive know-how and innovative spirit of our 26 employees. GuK has premises with a floor space of 1,500 square meters, the technical equipment of which is constantly being modernized and expanded. When the company was founded in 1994, it already had a manually operated punching machine, an automatic punching machine for small batches of up to 5,000 pieces, a band saw and a machine for automatically cutting hoses and molded parts to length, but later a laminating machine for coating existing materials as "self-adhesive" and a cutting plotter were added. The cutting plotter enables the cost-effective production of small batches without the need for a punching tool. In 2000, GuK entered the field of elastomer molded part production, where customer-specific, drawing-based parts are produced in series. Our water jet cutting machine has been in operation since April 2006 and a 3D printer since 2014.
