In-House Testing


The advantages of in-house testing for the Norma Group include a steady growth of know-how within the organization; rapid availability of test results for engineers and customers; elimination of external inspec- tions; and a reduction in delivery times. “The reliability of joining products is of major importance because they are con- sidered to be mission critical: if only one element develops a leak, this can have a negative effect on the entire vehicle’s ability to function,” Potts said. “For example, urea lines are a critical component of a vehicle’s emission-control system and SCR exhaust- gas after-treatment.” Norma Group engineers are developing the next genera- tion of joining systems with lighter-weight plastics that are even more resistant to high temperatures and pressures. And in accordance with its sustainability strategy, Norma Group also is using plastics that can be reused or recycled. “Plastic materials which can be reused or recycled are becoming more and more important,” Potts said. “They also offer an opportunity to replace conventional materials, which often are heavier and more expensive.” For example, the company recently announced the devel- opment of a new quick connector made of recyclable plastics such as fi berglass-reinforced polyamide 6 (PA 6) or polyam- ide 12 (PA 12). Norma Group’s V2-XC (X-treme Conditions) connector withstands especially high temperatures, pres- sures and vibration. Well-suited for trucks, as well as commercial and agri- cultural vehicles, the V2-XC can be used in systems for air intake and crankcase ventilation. The new connector can maintain temperatures of up to 150° C and overpressure of up to fi ve bar.


‘Steadily Increasing’ “Our customer requirements are steadily increasing,” Potts said. “It makes sense for us to continue development of plastic products.”


In addition to its development of new plastic products, the company also is testing its metal products with the goal to continually reduce weight and increase heat resistance.


An emplo ee studies a part dur ng V2 connector production. An employee studies a part duriing V2 connector production.


With hot-gas tests, for example, temperature fl uctuations of over 1000° C can be generated using a cooling system and a gas burner. V-profi le clamps that are used in the exhaust gas system are exposed to this type of stress. Norma Group invests approximately 5% of the turnover generated by its Engineered Joining Technology business in research and development. R&D of new technologies, prod- ucts and solutions, as well as modern test capacities, is a key element of the company’s strategy. The company manufactures a wide range of innovative connecting solutions and water management technology offer- ing more than 35,000 products to customers in 100 countries with around 6700 employees. Norma Group joining products can be found in vehicles and trains, ships and aircraft, build- ings and water-management systems, as well as in applica- tions for the pharmaceutical and biotechnology industries. The company had sales of approximately €895 million in 2016. Norma Group operates a global network of 28 produc- tion facilities, as well as numerous sales and distribution sites across Europe, the Americas and the Asia-Pacifi c region. Norma Americas is an integral part of the Norma Group. It manufactures high-quality clamps, connectors and fl uid systems with more than 1300 employees at nine production facilities in North and South America with annual sales of about €382 million.
