Five Things to Know About Automatic Crimping Machines
By Zachary Kozak, Marketing & Communications Analyst, Komax Wire

ire crimping is an important part of production lines that depends on the performance and reliability of a wire crimping machine. Such ma- chines are available in a variety of configurations, as both manual
and automatic systems. For larger production requirements, however, auto- matic wire crimping machines help original equipment manufacturers (OEMs) to meet demanding quality standards, such as the IPC/WHMA-A-620 and SAE AS7928 for wire crimping. In the quest for an optimum automatic wire crimping system solution, a manufacturer should identify five key re- quirements before adding an automatic crimping machine.
(1.) Understand the production volume that must be handled by a wire crimping machine. A wide range of wire crimping machines are cur- rently available from a number of vendors, ranging from semiautomatic sys- tems to fully programmable, computer-controlled systems with flexible, inter- changeable crimp and cutting modules and powerful control software. This available variety and number of choices can make a selection of a machine dif- ficult. But by running an analysis of the production volume that must be han- dled by a wire crimping machine, including the number or crimps required for each job, an automatic wire crimping machine can be optimally matched to the needs of a production environment. In addition, firms such as Komax Wire can help a specifier to understand how to make an optimum machine selection by consulting on the capabilities of semiautomatic machines versus fully au- tomatic wire crimping systems.

(2.) Understanding the requirements of a manufacturing facility's current and future applications. Product innovation, especially in industries such as automotive, military, and aerospace, is a main driver to an OEM's long-term sustainability. As products and applications evolve, so will the wire harness requirements of the customer. How will these application changes affect fu- ture production requirements? In regards to fully automatic crimping ma- chines, the flexibility of the machine should act as a defining characteristic for a typical contract manufacturer. Double crimping, military-qualified crimp- ing, ferrule crimping, tinning, and seal insertion are all common applications among OEMs in North America. When adding a wire crimping machine, fu- ture requirements should always be part of the planning and selection process.
(3.) Choosing the right crimping system supplier. A number of suppli- ers are available, offering many different types of wire crimping system solu- tions. A wire crimping system represents a major capital investment for any manufacturing facility and a firm that makes such an investment should ex- pect the full technical support of the system supplier. Many manufacturing facilities rely on one fully automatic crimping ma-
chine to meet all of their production needs, and technical service from the sup- plier is critical for maintaining wire crimping system performance or, in the worst-case situation, repair should a machine stop running. Some wire crimp- ing system suppliers train and certify their technicians across all products while others train technicians only for specific product categories. When se- lecting an automatic wire crimping system, the service structure and capabil- ities of the supplier should be considered as part of the purchase.
(4.) Product quality and performance. Specifications for different ma- chines from different manufacturers can be readily compared from data sheets provided on each company's website. In addition, some criming ma- chine suppliers may offer testimony from customers on their sites, allowing specifiers to review the comments of those who have selected and used differ- ent machines. In addition, the quality of today's automatic wire crimping systems is
very much connected with the available software for that system, such as crimp-force-analyzing (CFA) software. One of the fastest ways businesses can cut costs is by reducing unnecessary scrap material, and CFA software can help to reduce costs in manufacturing of wire and wire harnesses. This soft- ware can detect inaccurate strip lengths, missing strands, crimp height, and insertion depth. While many companies today may not use CFA software or techniques, making the necessary changes to incorporate CFA may pay divi- dends for such a small investment. Reducing the number of faulty crimps can save money in a manufacturing process.
(5.) The need for a durable and robust system that will provide reliable performance on wire crimps. Word-of-mouth referrals are usually the most accu- rate means of sorting through the different choices and supplier literature on dif- ferent wire crimping systems. When attempting to identify the strengths and weaknesses of different wire crimping systems, such as evidence of reliability and how the machine hold up over time. A low priced, low quality machine may look great on paper, but the potential problems, such as crimp repeatability, for
an aging machine may affect its long-term return on investment (ROI). Contact: Komax Corp., 1100 East Corporate Grove Dr., Buffalo Grove, IL 60089-4507 % 847-537-6640 fax: 847-537-5751 Web:
