Renewal of a machine tool bed
with WEICON WR
In this application, the original cast coating is first removed by heating to over 200 °C. The surface is then rebuilt using the steel-filled epoxy resin system WEICON WR. WEICON WR is particularly suitable for potting and gap filling applications as it offers high compressive strength and can be processed with precision. The area to be filled is slightly overfilled to allow precise mechanical reworking after curing. The surface is then milled and fitted with new cooling channels, restoring full functionality of the machine bed. WEICON WR enables permanent repair of the machine tool, reduces downtime and avoids high investment costs.
Manufacture of axle gaiters
with WEICON Mould Release Agent and WEICON Urethane 45
For the production of axle gaiters, a clean mould and reproducible casting process are essential for dimensional accuracy and function. The mould is first cleaned with WEICON Cleaner Spray S to reliably remove residues. It is then pre-treated with WEICON Mould Release Agent, which enables clean demoulding of the components. The actual casting of the axle gaiters is carried out with WEICON Urethane 45, an elastic polyurea casting resin with good recovery and high mechanical strength. The material cures to a flexible, durable structure and is ideal for reproducing different geometries. This allows axle gaiters to be produced economically and precisely without relying on expensive original parts – a flexible and cost-effective solution for mechanical engineering.
Bonding of polyethylene strips to aluminium rails
with WEICON Contact VA 30 Black and WEICON CA Primer for Polyolefins
In strapping technology, polyethylene strips are bonded to aluminium rails as sliding guides for plastic straps. Due to the very small bond gap and the low-energy surface of polyethylene, this application places special demands on adhesive technology. WEICON CA Primer for Polyolefins is first applied to ensure proper adhesion. The bonding is then carried out with WEICON Contact VA 30 Black, a rubber-filled cyanoacrylate adhesive with high strength and excellent shock and vibration resistance. This creates a permanently high-strength bond between polyethylene and aluminium that reliably withstands mechanical loads during machine operation.
Manufacture of truck axles
with WEICONLOCK® AN 302-71, WEICON Black-Seal and WEICON Flex 310 M® 2 K
In truck axle production, screw connections and sealing points must withstand extremely high mechanical and thermal loads. The screws on the differential gearbox are secured with WEICONLOCK® AN 302-71. This high-strength, medium-viscosity threadlocker reliably prevents loosening even under strong vibration and high loads. The differential is sealed with WEICON Black-Seal, an oil- and grease-resistant silicone sealant. WEICON Flex 310 M® 2 K is used for sealing and bonding additional vehicle components. This fast-curing, elastic adhesive enables full-surface bonding and bridges gaps of up to ten millimetres. The combined use of these products creates permanently secure, load-bearing and assembly-friendly connections that reliably meet the high demands of mechanical and commercial vehicle engineering.
Bonding of roller journals
with WEICONLOCK® AN 306-30
When joining roller journals in mechanical engineering, precise and highly durable connections are essential, especially at high speeds and under torsional forces. The inner surfaces of the rollers are first mechanically roughened and then thoroughly cleaned with WEICON Surface Cleaner to ensure optimal adhesion. Bonding is carried out with WEICONLOCK® AN 306-30, a high-viscosity, high-strength retaining compound. It is especially suitable for passive material combinations such as aluminium and stainless steel. The adhesive reliably withstands dynamic loads and high speeds and ensures a permanent force-locked connection. Thanks to the ergonomic WEICON Pen system, AN 306-30 can be applied easily, cleanly and with minimal material waste, making it ideal for precise applications in mechanical engineering.
Bonding of nitrile butadiene rubber (NBR) to steel on gripper jaws of a paper roll cutter
with WEICON GMK 2510
For the permanent bonding of NBR rubber to S355 steel, the materials are first mechanically roughened and then thoroughly cleaned with WEICON Cleaner Spray S. Both surfaces are then coated with WEICON GMK 2510 contact adhesive. After an evaporation time of around 10 minutes, the materials are joined and tapped with a rubber mallet. The temperature-resistant, impact-resistant two-component system ensures a strong and reliable bond even under mechanical stress. Thanks to simple processing and high adhesive strength, this method is particularly efficient and durable in mechanical engineering.
Temporary securing of workpieces during wire EDM (wire electrical discharge machining)
with WEICON Contact Gel and WEICON CA-Remover
During wire EDM, workpieces must be fixed as any movement could damage the precisely manufactured components. With a gap of around 0.3 mm, premature movement is particularly critical as it could cause the part to tilt. WEICON Contact Gel is pressed into the gap with a spatula, activated with water and then left to cure for around 10 minutes. Through shock curing and the curing time, the adhesive reaches the required strength to prevent tilting. After EDM machining, the adhesive can be reliably removed using WEICON CA-Remover. In this way, residues can be removed more easily than with previously used two-component epoxy adhesives.
Sealing of metal housings in the manufacture of emergency lighting systems
with WEICON Flex 310 M® HT 200
In the manufacture of emergency lighting systems, metal housings are reliably sealed with WEICON Flex 310 M® HT 200. Sealing is carried out prior to powder coating and requires even application with high positional accuracy, as the components are safety-critical. The Pressure Gun Airflow 3 enables precise application of the sealant, allowing both flow rate and material quantity to be accurately controlled. This results in a uniform and durable seal that meets the requirements for safety, resistance and further processing in mechanical and plant engineering.
Bonding and securing of housings in the production of agricultural machinery
with WEICON Easy-Mix RK-7100 and WEICONLOCK® AN 302-43
In agricultural machinery – particularly in engine-driven mowers for steep slopes and challenging terrain – housing joints must withstand extreme loads. The base unit can be equipped with various attachments and therefore requires a connection technology that is both robust and flexible. The housing is bonded using WEICON Easy-Mix RK-7100, resulting in a high-strength, durable joint. In addition, WEICONLOCK® AN 302-43 is used as a threadlocker to reliably secure fasteners against vibration and dynamic loads. This combination ensures dependable performance even under harsh operating conditions typical of agricultural and construction equipment. At the same time, adhesive bonding enables cost-effective and efficient production in mechanical engineering.
Maintenance and servicing of injection moulding tools for long-lasting performance
with various WEICON products
For reliable corrosion protection during storage, WEICON Corro-Protection Magenta is used – a wax-based protective coating that prevents flash rust. Before reuse, the tools are cleaned with a mould cleaner. For the lubrication of ejectors and moving components, WEICON Anti-Friction Spray MoS₂ or WEICON PTFE-Spray can be used; these grease-free dry lubricants reduce friction. For particularly demanding metal components, WEICON Anti-Seize High-Tech is recommended – a metal-free assembly paste that reliably prevents seizure, wear and contamination. In addition, mould release agents facilitate demoulding and ensure smooth production processes. The targeted combination of these products ensures effective corrosion protection, high temperature resistance and the maintained functionality of the injection moulding tools.
Thread sealing of pump pipelines
with WEICONLOCK® AN 305-77
Before assembly, the threaded joints of the pump piping are thoroughly cleaned with WEICON Cleaner Spray S to remove oil and dirt residues. WEICONLOCK® AN 305-77 is then applied as a thread sealant. Compared to conventional sealing with hemp, the anaerobic sealant reduces application time by up to 75%. After full curing, a pressure test confirmed that the assembly reliably meets the required specification of 4 bar. The simple assembly process and significantly reduced installation time increase productivity and ensure reliable and repeatable sealing in mechanical engineering.
Bonding of polycarbonate brackets for cable harnesses in vehicle construction
with WEICON Easy-Mix RK-7000
In the underbody of fire service vehicles, polycarbonate brackets are used to securely fix cable harnesses. The brackets are bonded to various metal substrates, including hot-dip galvanised surfaces as well as wet-painted and powder-coated metals. Bonding is carried out using WEICON Easy-Mix RK-7000, whose broad adhesion range enables reliable bonding to a wide variety of surfaces. The rapid curing of the structural adhesive is optimally matched to the specified cycle time and supports an efficient manufacturing process. This ensures a permanently secure fixation of the cable brackets, even with varying substrates and high demands in vehicle construction.
Filling the gap on a rotor shaft in a gravel washing plant
with WEICON WR
For a load-transferring connection of a rotor shaft in a gravel washing plant, a gap injection is carried out using WEICON WR. The free-flowing, steel-filled epoxy resin is introduced into the existing gap and completely fills it. After curing, a high-strength bond is formed that provides both a form-fit and force-fit connection and reliably withstands the mechanical demands of the system. The simple application enables rapid and cost-effective repair in mechanical and plant engineering.
Bonding of brass screw caps in polycarbonate control housings
with WEICONLOCK® AN 301-70
During the manufacture of control housings, brass screw caps are bonded into polycarbonate housings. Following a material change to polycarbonate, an adhesive and sealing solution is required that ensures a secure bond without damaging the plastic material. The use of WEICONLOCK® AN 301-70 enables reliable bonding while featuring a reduced acid content. This significantly minimises the risk of stress cracking in the polycarbonate. The solution is ideally suited for use in mechanical and equipment engineering and supports durable, process-reliable production of the control housings.
