And so the next one hundred years begins

capability, which offers economic advantages in industrial assembly because, compared with metric screws, there is no need for time-consuming part preparation and the number of work steps can be reduced. For example the ALtracs® Plus screw, which is specially designed for light alloys and other non-ferrous metals, can be fastened directly into the cast hole of transmission housings or steering columns. For applications with the ALtracs® Plus screw, the ALtra CALC® prognosis program provides further valuable support, and FEM-supported component design is also possible. The self-tapping SHEETtracs® screw is most suitable for the process-reliable assembly of pre-punched thin sheet joints. A typical application for the SHEETtracs® screw is fastening of housing walls of washing machines or dryers. And for direct fastening into thicker steel materials, the Spiralform® screw guarantees a secure and long-lasting connection.

Fastening technology for composite and lightweight design Lightweight and composite design is continuously being integrated into almost all components of future vehicles. Auto body construction in particular is characterized by a wide range of materials used. If, in addition to one-sided accessibility during assembly, the removability of the fastener is also important, the flow drilling FDS® screw is the fastener of choice. The screw fastens steel sheets and aluminium without the need of a pilot hole and with exceptional quality. The FDS® screw is constantly being further developed; for example, a version with a special sealing function is used for fastening battery systems of electric vehicles. Another option for joining different materials and semi-finished goods is the so-called EJOWELD® “friction welding”. This innovative development now provides the option to join composite designs, in particular lightweight materials and ultra high-strength steels, with a friction element installation tool suitable for robots. With EJOWELD® the joining process is fast, automated, high strength and reproducible.

Fasteners for foam and sandwich structures EPP (expanded polypropylene) foams are often used in applications that need to be as light as possible or that have to absorb large amounts of energy in a very short time in an emergency, such as crash pads in car door modules. EJOT® EPPsys is a product group specially designed for connections in this material. These plastic fasteners can be screwed directly into the foam. Going one step further, the EPPsys RSD friction weld dome is inserted directly into the EPP foam using the friction welding process, bonding with the molten material. A similar process is also used by the TSSD® thermal adhesive bonding boss, which penetrates the component by means of rotation and the associated heat input and creates a positive-locking connection. In addition to rear window shelfs and loading floors from the automotive sector, the application portfolio also includes the sandwich and honeycomb structures frequently used in aviation, in which the TSSD® can be used to set fixing points in the aircraft galley, lavatory or baggage racks.

The operational suggestion and recommendation scheme is introduced. An important innovation, which over the decades has led to permanent improvements in everyday production. Employees whose suggestions are acknowledged receive a “reward.”

Fastening solutions for the micro range The trend toward miniaturisation of components continues across all industries. “Smaller, lighter, more efficient” is also the demand on the fastening technology. With the self-tapping EJOT micro screws significant weight and costs savings can be realised even in the smallest installation space. They have all the advantages of the larger dimensions and, due to their tight fitting thread, achieve high mechanical strength even in difficult installation situations. Due to their self-tapping geometry inserts are unnecessary. In the final assembly of components the EJOT micro screws can be used flexibly. This ranges from manual assembly to automated serial assembly, which is already standard in the numerous industrial micro applications. The field of applications for micro screws is wide. It ranges from small housings that need to be fastened, for example sensors in radar systems or rearview cameras in modern cars, to circuit board screw connections in the sound processor of a cochlear implant.

Individual precision cold-formed parts The variety of possible applications for cold-formed parts made of steel, aluminium or copper is virtually unlimited. The EJOFORM® cold formed parts are always tailored to the customer's specific application. They fulfill a wide variety of functions, for example as a bracket, stop bolt, spacer and contact sleeve, adjusting element or safety-relevant component in braking systems. The individual products are manufactured in a multi-stage cold-forming process. With this technology, a wire section is formed into a complex cold forming part over several forming steps. Individual finishing steps and refinements are then possible, for example machining or coating. In many customer applications, this means that instead of several parts having to be assembled to form a complete functional part, only one EJOFORM® part is used. Particularly in comparison to turned parts with a great deal of material input, the customer also benefits from the economic advantages of this manufacturing process, which become greater the higher the production quantity and thus the material savings.

Hybrid parts and components EJOSYST® is the term for individually developed functional components made by EJOT. In customer applications, these parts can take on a wide range of functions, such as compensating for manufacturing tolerances or thermally induced length changes, fastening, positioning, sealing or even transferring motion and torques. Various sized headlamp adjustment systems are also part of the EJOSYST® portfolio. Both manual and motorised adjustments are possible. The range of applications includes a wide variety of lighting systems such as halogen, LED or laser applications in cars and trucks. EJOSYST® products are based on plastic injection molding and cold forming technologies. Focus of the development is always the individual solution for customer-specific requirements. The assemblies are found, for example, in electronic parking brakes, car seat adjusters or in the onboard electronics of electric vehicles.

Highest quality – sustainable

In the Construction market unit, global quality leadership in the Building Fasteners and ETICS Fasteners customer segments was and is the driver behind all developments.

>>Text: Jutta Rathmann

Of course, this also applies to the “Distribution” customer segment that was newly created at the beginning of 2022. “Highest quality – but also sustainable,” one would add today, even if the topic of sustainability is not a trend that came about only recently. Quality and sustainability are by no means contradictory. They are the basis for many innovative products and further developments. With numerous business areas, the Construction market unit is much broader than its well-known competitors. “Everything from a single source” is the customer-friendly idea behind it, which includes not only high-quality application solutions, but also comprehensive services.

In the Building Fasteners area, the original concentration on fastening solutions for the building envelope of industrial buildings (industrial lightweight construction (ILB), flat roof (FLD) and rainscreens (VHF)) was initially supplemented by applications for solar, window and glass facade technology (FGF). Timber as a material has been noticeably gaining in importance for industrial buildings for years, so that EJOT Construction is also taking up this challenge. Especially since the other young business field of anchoring technology is full of synergy effects for timber construction and rainscreens.

The inclusion of synergy effects and the system concept with a view to the big picture are particularly important in the Construction market unit. In the future, we want to not only supply high-quality connecting and fastening elements, but also offer our customers comprehensive and holistic systems. This system concept also requires a fundamental rethinking in sales, because in the system concept this takes place exclusively as a project business. The focus here is on planners and architects in particular – an important task especially for sales engineers.

“Everything from a single supplier” also means that the business activities of the Construction market unit is by no means limited to products. Service related to the application of the products plays a central role, from the pre-dimensioning to the pull-out test on the construction site to the rental or sale of self-developed setting or assembly devices and the offer of software tools such as ANCHOR FIX (a new and convenient dimensioning software for anchoring products) or the ETICS product configurator.

By definition, an external thermal insulation composite system (ETICS) is related to ecology and sustainability. The high-quality products of the customer segment ETICS are sold exclusively through system providers. This ensures that all components in the system work together. In Europe, EJOT is the industry leader in the field of ETICS anchors with many unique selling points. The ISO family for fastening attachments provides additional products that help to improve the overall performance of an external thermal insulation composite system. The ISO-Bar ECO for greening ETICS facades takes the ecological idea into account in a special way. Profiles for all applications complete the ETICS range.

1990

In January 1990, the construction of the 2800 square meter hall at Bienhecke in Bad Laasphe is completed. The setup of the storage space and the EJOMAT department follows. In addition to the shipping, packaging and final inspection departments, space is also created for a new electroplating shop.

How sustainable are EJOT's ETICS and Building Fasteners products really? In the Construction market unit, improvements are constantly being made, like the use of recycled or bio-based plastic. With EPDs (Environmental Product Declarations) which were obtained on a voluntary basis, Construction already enables its customers to objectively evaluate the product-specific carbon footprint. Being an industry leader, remaining innovative and actively shaping the future – this includes getting involved in committees, boards and trade associations in the construction industry. This is how trends are set and product developments are designed at an early stage – corresponding to the market development of designs and systems. E

Professional applications for the building envelope

The EJOT Market Unit Construction caters to selected segments of the building industry with professional applications on facades and for the interior construction of buildings. EJOT offers a wide product range, special fastening know-how and customer-specific service in the different core segments.

>>Text: Katrin Strübe

Industrial Lightweight Construction This core segment focuses on innovative fastening elements for attaching trapezoidal profiles and sandwich panels to structures made of steel and wood. The classic product in this area is the self-drilling screw JT3-2H-Plus-5.5. For years, it has been an integral part of the EJOT core business.

The optimised and unique tip geometry of the new EJOFAST® Plus self-drilling screws enables safer application to the surface thanks to the even more finely shaped tip. Displacement or slipping is almost impossible. At the same time, the load-bearing capacity values were improved once again. The slim, single-start threaded drill point produces no sharp-edged swarf that gets stuck in the material and require time-consuming removal.

With the new self-tapping screw JZ5-6.3, EJOT offers a twosteel self-tapping screw with a hardened thread-forming zone, which is characterised by a particularly high level of process reliability when thread-forming. It is the strongest EJOT screw on the market so far. Self-tapping screws, also known as thread-forming screws, do not have a drill point. In a preceding work step, a through hole is created. However, the thread is formed automatically when the screw is then tapped in, eliminating the need for work steps and other tools such as tap drills or additional fastening elements such as washers and nuts. Self-tapping screws are mainly used for particularly thick or high-strength steels, where self-drilling screws reach their process limits. Timber construction The goal of the Market Unit Construction is to be able to offer solutions for all building areas in which fastening elements are required. It is therefore a logical consequence to include products for timber construction in the portfolio.

Whether for fastening above-rafter insulation, in stair construction or interior construction – T-FAST® wood screws are ideal for the fastening of wooden components in structural and non-structural timber construction.

With the T-FAST® series, EJOT offers a range of zinc-plated wood screws that are regulated by ETA-18/0812 and correspondingly CE-marked. The wood screws with partial thread enable strong contraction and firm connection of the wooden components with rapid work progress. They can be installed in areas that are not weather exposed or in usage classes 1 and 2 according to EC5. Rear Ventilated Facades The rear-ventilated facade offers great design freedom and versatility. EJOT is a system provider and reliable partner in this area. The various system components, services and comprehensive advice lead to a homogeneous but individual solution.

Our award-winning CROSSFIX® substructure system is a revolution in rear-ventilated curtain wall construction. It is the first stainless steel substructure that can be equally used for horizontal and vertical support profiles. The use of 100 percent stainless steel significantly reduces the thermal bridge allowance in the system. CROSSFIX® increases the flexibility, facilitates assembly and simultaneously reduces storage costs. The system has an ETA rating, which reduces the amount of planning, creates cost certainty and saves time and money.
