We’ve all had annoying experiences with loose threaded fasteners, such as loose screws in eyeglasses or door handles. In the worst case, they can even lead to truly hazardous situations. With its innovative ThreadLoc system, Arnold Umformtechnik has now developed a unique complete range of chemical and mechanical thread locking technologies that can meet the need for keeping screws and bolts tight in every situation.

The automotive division of Hetal-Werke, located in Alpirsbach (Germany), is intensively looking for alternatives to conventional joint technologies. In the future, ATP^® TriPress fasteners from Arnold Umformtechnik are expected to be used in place of conventional weld-on studs. These press-in studs match the requirements profile of the company, which specialises in the full scope of kinematic subassemblies and hinges in the passenger car seating area.

Alufast^® aluminium screws from Arnold Umformtechnik are especially advantageous for joining magnesium components: transmission, housing, load-bearing, stiffening... Especially with material pairs exposed to thermal stress, they significantly enhance the security of threaded fastener joints. Furthermore, Alufast^® aluminium screws weigh only one-third as much as equivalent steel screws. Particularly with large volumes the weight savings can amount to the equivalent of several metric tons of steel per year.

“Conform” product line is made of multifunctional precision parts produced by metal forming instead of turning. This change in production method alone is sufficient to allow cost savings of up to 80% to be achieved.

The number of vehicle failures due to electronic components is increasing every year. Electronic components are involved in nearly half of all emergency assistance calls received by the German motorists’ association ADAC. Often coming from screws, microscopic contamination particles on interconnects regularly cause failures in control units. To solve this problem, Arnold Umformtechnik has developed the Cleancon concept.

The RIVTEX system solution from Arnold Umformtechnik and Arnold & Shinjo is a high-quality alternative to conventional welding. It cuts parts assembly costs whilst assuring every quality requirement.

The “innovation factory” is housed in the company’s historic original building. Experienced ‘old hands’ work side by side with bright new talent on research and development projects for the new joining systems of tomorrow and the day after.

Remform screws from Arnold Umformtechnik GmbH & Co. reduce the overall assembly cost of plastic parts as they do not require nuts or inserts. They furthermore ensure the highest levels of assembly security, due to a specific design that creates a large difference between the forming torque and the stripping torque. The main application of REMFORM for plastic parts assembly is the automotive industry.

Taptite 2000^® generation of thread forming screws combines efficiency advantages with process reliability. A total cost saving of up to 88% can be achieved in threaded fastener assembly.

Arnold provides two new reliable and cost-effective assembly methods to answer to the continuously evolving use of plastics. Remform screws is a solution for detachable plastic parts joints whereas Arnorld Tripress (ATP) are dedicated to permanent joints for ductile light metals or plastics.
