Fasteners for precision weighing Swedish specialist fastener manufacturer Bumax has supplied its premium Bumax 88 fasteners for one of Flintec’s most recent weighing modules to meet industry strength and reliability requirements as well as European standards. manager at Flintec Germany. “The Bumax 88 fasteners used in our 55-20 weighing module have proved to be highly reliable and we have had no issues to date. We are very likely to use Bumax fasteners on future products, depending on the environmental and design specifications we have.”

in faster deliveries, lower costs, better logistics and, consequently, our Asian customer satisfaction.” The purchaser of the new Vector furnace is a manufacturer specialising in flat thread rolling dies, header punches, various bolt forming tooling and drill point dies, with 30 years of experience. For further busi ness development, the customer needed to add a vacuum furnace that would allow treatment of tools for fastener production. Liu Yedong, managing director of Seco/ Warwick China, commented, “Vector gives our customers the comfort of reliable production planning as well as great flexibility and independence. The parts produced must be of high quality, because they are subject to very high requirements in terms of quality, durability and precision. “Thanks to the unique design benefits such as directional cooling, we can be sure that the final product will meet these high expectations.” Seco/Warwick, Inc www.secowarwick.com silos, tanks or other storage solutions. The built-in load cell offers a wide range of precise weighing capacities from 7.5t to 300t. The 55-20 is equipped with an integrated lift-off system and bump stops. The low-temperature toughness of Bumax 88 is a crucial property for the 55 20 weighing module that helps to avoid breakages in low temperatures, when conventional steel can become brittle. The module has an operating temperature range of -40°C to +80°C. The enhanced properties of Bumax 88 fasteners are achieved through a higher molybdenum content (minimum 2.5 per cent), a unique manufacturing processes and the sourcing of high quality European steel.

Flintec, a manufacturer of precision weight-measurement technologies, chose Bumax as the supplier of premium fasteners for its latest load cells. The load cells are electro-mechanical sensors used to measure force or weight, and provide accurate performance across a diverse range of applications, from automating car manufacturing to weighing shopping at supermarket checkouts. New types of load cells are continuously being designed to meet the needs of this ever-changing market. “When we designed the new 55-20 weighing module, Bumax was able to meet all our demands for high-strength fasteners to ensure performance and reliability,” said Klaus Fuchs, engineering

The properties of the Bumax 88 stainless steel fasteners include high strength, corrosion resistance and durability. They are also maintenance-free. The Flintec 55-20 weighing module is a low-profile unit that enables customers to install load cells beneath the legs of their

the furnace, even parts with problematic shapes. The furnace is equipped with a convection heating system to improve heat transfer efficiency during heating at lower temperatures. A round heating chamber with good temperature distribution and an efficient and ergonomic vacuum pumping system are characteristics of this furnace. An efficient cooling system ensures a maximum hardening pressure of up to 15 bar abs. “Asia is an important market for us, where we have had our branch and production

An Asian thread rolling die conglomerate has chosen Seco/Warwick as a vacuum furnace supplier. The Vector® on order will be used for vacuum hardening and tempering fastener dies, and will be the third delivery for this customer. The Vector vacuum furnace ordered features a compact design. The heating chamber’s medium size (600 x 600 x 900) enables efficient simultaneous heat treatment of many types of parts. The characteristic feature of the design is directional cooling, which ensures uniform cooling of all of the work inside
