Success with fastenings

Early cooperation is a factor of success – proven cost reduction throughout the value added chain – quality increased by greater process reliability.

(PresseBox) (Forchtenberg, Germany, ) Prices are the result of costs. This simple formula is the basis on which Ubrig & Söhne, an industrial engineering company based in Heiligenhaus in Germany, has formed its company philosophy - to be included at an early stage in its customers’ development processes. Together with its own suppliers, the company develops Integral solutions right from the start of the project. The result has paid off in many years of trust in the company’s skills and expertise. Within the automotive industry Ubrig & Söhne is known as a company, which, by closely cooperating with experienced suppliers, makes no compromises on quality - even under extreme cost pressures.

Confirming this philosophy, Mario Metzger, Product Manager at screw specialist Arnold Umformtechnik GmbH, Ubrig & Sohne’s longstanding development partner, said: “throughout the 15 years we have worked with Ubrig & Söhne we have been involved at the earliest possible stage with new development projects.” Since the beginning of the 1990s Ubrig & Söhne has been using Arnold Remform threadforming screws for its fastenings. It was then that Ubrig started to carry out its component assembly with traditional screw fastenings on a bigger scale. Remform screws became the obvious choice due to their low screw-in torque and high overtorque. They complied with the specified requirements profile to the fullest extent. And they are much less expensive than metric screw/nut fasteners. “At present around 80 percent of our screw fastenings are Remform products from Arnold,” said Peter Langer of Ubrig Industrial Engineering.

Plastic gains recognition
Together with Arnold Umformtechnik, Ubrig & Söhne has made its mark on the process of direct fastening into plastics. As they worked together, both companies had recognised at an early stage that plastic was increasingly in use as a material in the automotive industry. Its moulding capacity, the weight, and recyclability are all positive points in favour of the synthetic material. “The comparatively flexible material is particularly suitable for direct screw fasteners,” commented Langer, explaining the decision to buy fasteners from Arnold. “Thread-forming screws are particularly advantageous where the core hole is pre-cast.”

In close cooperation with the design engineers at Arnold, Ubrig & Söhne soon recognised that Remform fasteners in particular have a positive effect on costs. There is no need for inserts or inlays, so the cost of materials goes down. The high screw-in speed achieved and the fully automated casting of parts means that cycle times are short. Plant utilisation and productivity increase consistently. “The reduction in costs is running at over 60 percent compared with traditional fasteners”, stated Langer, as he justified the decision to go for this type of fastener technology.

New qualities
Such effects are the result of the special capacity of Remform screws to form the thread itself. The asymmetric thread geometry of Remform screws is constantly opening up new application fields on the product line at Ubrig & Söhne. The patented profile reduces the edge stresses that occur as the thread is formed. The flank angles, which diminish towards the crest of the thread, ensure that radial stress is reduced. This considerably reduces the risk of the boss splitting; at the same time Remform screws increase the safety of the joint. The flank that is averted away from the screw head has been provided with a radius. The steep side that has moved towards the head retains the plastic and raises the flank overlap. This guarantees high cross-thread forces while maintaining tensile force and torque. And the steep flank also ensures that the driving forces are transmitted axially - in the correct direction. Compared with 30-degree low angle screws the engineers at Ubrig & Söhne were able to prove strip load measurements and the difference between minimum overturn torque and maximum screw-in torque can often be well over 30 percent.

“Overall we are using a proportion of around 80 percent of direct screw fastenings in plastic – and it is rising”, continued Peter Langer. “This development will continue.” Together with the specialists at Arnold we are able to comply with the quality parameters set by the manufacturers, even under heavy cost pressure.”

The ARNOLD Group – solutions which connect
Whereas the Arnold name has always signified and still does stand for “fasteners”, in recent years the range of products has expanded.

Today, Arnold is a group of companies supplying a comprehensive range of fastener products and related services besides the parent company ARNOLD UMFORMTECHNIK GmbH & Co. KG, Forchtenberg-Ernsbach in Germany, members of the Arnold Group include subsidiaries Arnold & Shinjo, also based in Forchtenberg-Ernsbach, Germany, and ARNOLD Technique France, based in Lyon, France. In 2003 the overall group, employing just under 500 people, achieved a sales turnover of over Euro 80 million. The transformation from a purely manufacturing company into a comprehensive service provider to the fastener industry began in the mid 1970s, when the company decided to conccentrate on manufacturing very high-quality technological fasteners. As it entered the higher quality fastener market, the company faced new challenges. Today Arnold works with major companies in the automotive and electrical industries, both at home in Germany and abroad, and becomes involved early on as their customers develop and design new parts. First of all this requires intensive on-site consultation along with comprehensive customer services, and secondly it requires highly qualified employees who can rise to, and meet the demands of the market.

•To be able to meet the particular demands of each of the industrial sectors, Arnold has divided its marketing activities into automotive and trade and industry divisions. Thus, customers can call upon specialist teams able to offer customised advice in order to provide innovative solutions.

•To meet the challenge of such development partnerships, our qualified staff develop the best possible fastener solutions by visiting customers at home and abroad, and implementing the results of their visits at our own engineering design and development departments.

•By constantly analysing industry applications, the products themselves, and users´requrements, ARNOLD is always in an excellent position to be able to develop new solutions to problems and incorporate thm into the development process. So, with ARNOLD´s own production expertise, we are able to produce top quality innovative products and individual industry solutions that set new market standards. Furthermore, ARNOLD is an important and integral part of the Supply Chain. Working very closely with OEMs and their suppliers, ARNOLD is able to react very quickly to changes in the market, and to incorporate the knowledge gained into enhanced products for customers. A Pre-Sales and After-Sales service covering Key Account Management, modern logistics systems and customer seminars rounds off the range of ARNOLD services.

The Arnold Group is a wholly owned subsidiary of the Würth Group, which with over 50,000 employees and more than 320 companies world-wide operates on a global basis with earnings of over 6 billion euros. So, against that background, the Arnold Group represents a secure partner in the best possible position to serve the global requirements of the market.

Die ARNOLD Gruppe – Lösungen, die verbinden
Wurde der Name Arnold in der Vergangenheit noch oftmals automatisch mit dem Begriff „Verbindungselemente“ gleichgesetzt, so hat sich dies in den letzten Jahren grundlegend geändert.
Heute ist Arnold eine Unternehmensgruppe zu der neben der Muttergesellschaft ARNOLD UMFORMTECHNIK GmbH & Co. KG, Forchtenberg-Ernsbach (D), noch die Töchter Arnold & Shinjo, ebenfalls Forchtenberg-Ernsbach (D), und Arnold Technique France, Lyon (F), gehören. Die Unternehmensgruppe erwirtschaftet mit knapp 500 Mitarbeitern über 80 Mio.€ Umsatz. Der Wandel setzte bereits Mitte der 70er Jahre ein, als man sich auf die Herstellung von anspruchsvollen Verbindungselementen konzentrierte.
