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.

Performance profile
The product portfolio includes commercial products, usually fittings, sheets, insulation products, foils and adhesives, as well as in-house products. These are the core areas of hose technology, profiles, sealing technology, molded parts and coatings. Elastomers, foams and rubber are processed. One of GuK's strengths is the customer-specific assembly and finishing of merchandise.
In summary, it can be said that GuK offers a wide range of products that leaves no questions unanswered. In order to meet this requirement, GuK also offers containers, special technical lubricants and products in the areas of pump technology, safety and the environment in addition to the basic range.

Quality
GuK introduced a quality management system shortly after it was founded and has been certified in accordance with DIN EN ISO 9001:2015 since 1996. The core idea of GuK is: "The customer is at the center of our actions, to inspire him, his loyalty and satisfaction, is the goal of all employees". We want to be a competent and reliable partner for our customers.
