Eckold Clinching The joining technique of the future Clinching technology Product program Drives Quality monitoring References for sheet metal and profiles Eckold Clinching is where the future of joining technology begins. Starting with this catalogue the method known as “press joining“ will now be referred to as clinching. Eckold clinching is the innovative and proven technique for joining metal sheets and profiles. The permanent joints are created by cold forming alone, without the use of additional or ancillary parts. The most significant feature of this technique, which is established in the DIN 8593 standard, is that the joint is formed from the material of the metal parts to be clinched. Not only that, the parts to be clinched can be of the same or differing sheet thickness and be made from the same or different materials. The requirements of joints are so diverse that Eckold takes the individual requirements of the user into account. Eckold offers an unsurpassed diversity of joint types in order to allow the ideal clinch to be made for the respective application. Eckold clinching has proven its worth both in use in automatic production lines or with robots and with portable tooling. Clinching of oil-impregnated or painted panels or stainless steels and its ability to cope with fluctuations in sheet thickness are only a few of the advantages that have helped Eckold establish a prominent position in the market. In addition, Eckold offers a joining technique with which metal panels of aluminium alloys or non-malleable materials such as spring steels can be joined to malleable materials. Furthermore, Eckold clinching has special advantages with respect to the environment. No toxic welding vapours or emissions, no noise pollution and low energy consumption present the user with improved working conditions. In comparison with conventional joining techniques, the Eckold clinching offers a saving of up to 55% for investment costs and 25% for operating costs. Technologically, Eckold has remained true to its reputation as a trend-setter. Not only did Eckold introduce the clinching technique to industry 25 years ago, the company more recently set a new milestone with the economical clinching of stainless steels, thus continuing progress for joining technology of the future. 2 The basis of our success is our extensive product range... ... starting with a widely varied tool programme through to a comprehensive range of standard machines and complete production systems: Portable Tools CONECO 45/60 easily portable, mobile, electric, electrohydraulic, hydraulic or pneumatic driven tools Modular MZD 60/6 C-frame range mobile tool with modular construction adjustable fixed C-frame for mobile or stop and large jaw stationary use capacity 3 Multipoint tooling Multipoint tooling for use in presses Stationary machines DFG 500/80 E universal machines, large throath, electrically driven Special installation Automatic production systems 4 The Benefits of Eckold Clinching. Eckold Clinching stands out from other joining techniques as a result of the following benefits: • no thermal effects on the clinch area • no toxic gases or vapours arising • no preservative afterwork • no additional or ancillary parts • no pre-treatment of surface • technique compensates for fluctuations in sheet thickness • also suitable for joining coated sheets • electricity or compressed air are the only energy sources required • suitable for joining sheets of different materials and thicknesses • non-destructive quality assurance possible Examples Engine bonnet – motor car Casing for laboratory or domestic appliances Window opener – car door Flow safety device – gas heating appliance 5 An unsurpassed range of variations for individual problems.

Economic viability and costs Cost comparisons of customers and independent bodies have shown that Eckold clinching is significantly more cost-effective than other joining techniques. Depending on the joining task, the overall costs for the manufacture of a clinched component are approximately 55% of the costs for spot welding, for example. This takes account of both investment costs and operating costs.

This takes account of the user’s health in many respects. Besides the significantly lower physical stresses, Eckold clinching is distinguished by low energy consumption and no industrial effluents whatsoever are generated. All in all, the Eckold technique is a clean and user friendly process. A manual method and a computer-aided online monitoring system can be used for quality control of Eckold clinching. The quality of the clinch element can be examined manually by means of the bottom thickness or width. 100% control is provided by the computer-aided online monitoring system. This can be used to achieve unbroken quality control in automatic plants for mass production. Production becomes more efficient and cost effective because down time and rejection rates are reduced through early detection of load errors.
