As versatile as the range of possible applications for fastening technology, as versatile are the possibilities for the production of cold-formed fasteners. EJOT EJOFORM® products are innovative and customer specific fastening and design engineering solutions. They meet various requirements, such as bracket, stop bolt, spacer or adjustment element. The individual products are manufactured in a multiple step cold-forming process. With this technology a wire section is formed into a complex fastening element in up to six blows.
EJOFORM® products are engineered parts consequently designed for the customer specific case. Early involvement of the EJOT application engineers offers great possibilities to make use of the numerous cost saving potentials and application optimisation. Expert monitoring from the first concept idea to the launch of production is an important part of EJOT's operating principle.
The special optimisation possibilities for EJOFORM® products can best be explained with an example. The EJOFORM® cold-formed component (image to the right) is produced in a 5-step cold-forming process and it saves ca. 25% of material compared to a turned part (image to the left). Other application engineering advantages also arise. For example the EJOT solution with integrated external hexagon recess can transfer much higher tightening torques compared to the slotted recess. The cold forming part can also be equipped with every type of thread (here DELTA PT®), in order to meet all possible requirements and materials.
The economic advantages when using EJOFORM® products are due to the manufacturing procedure. The relatively high launch costs, caused by high tooling costs, amortise with a certain quantity depending on the product, due to the high efficiency and economy. Compared to a turning or milling production the relatively high output of forming machines results in a significant improvement of the costs structure for the customer, which becomes even more distinct with large quantities. Even material cost savings of up to 80% - depending on the product design - are realistic.
The accurately manufactured EJOFORM® fastening elements can be adjusted or improved through different processes. Depending on the application and individual requirements EJOT delivers optimised fastening technology all from a single source.
In order to realise for example drill holes, clearance grooves, balls or undercuts, parts with complex geometry can be machine finished. Internal threads which are formed and not cut can also be realised according to customer request.
EJOFORM® products are produced from various materials. Mainly tempered steel and aluminium are used, but if required the parts can also be manufactured from stainless steel. The common strength category is achieved through heat treatment according to DIN ISO 898, for special threads the respective EJOT company standard is applied. Galvanic coatings correspond to DIN EN ISO 4042, other platings, for example to withstand up to 1.000 hours salt spray testing, are also possible.
