Automotive

Especially in the car interior, a lot is being glued with hotmelt. But hotmelt is also frequently used in bodywork construction (e.g. bumper linings), sound insulation, convertible rear window assembly or for bonding and sealing of headlights. Hotmelt is also increasingly being used in electronics, cable production and sensor technology.

Automotive Interior

Roof linings, cockpit or instrument panel, dashboard, centre console, seats and headrests, door panels as well as door mirrors or parapets, armrests, A- / B- / C-pillars, trunk equipment are finished with fabrics, foils, leather or other materials. The adhesive is applied to a wide variety of materials with balti hotmelt systems in dot or caterpillar form, usually by means of automatic robot application, or flat by spraying, slot nozzle or roller technology prior to laminating, laminating, folding, joining or pressing.

Coating of sheets prior to lamination

Cut-to-size fabrics, foils, foam foil composites or leather are first coated with a roller applicator and then reactivated on laminating machines and pressed with the carrier part.

Bead application prior to edge folding

An adhesive valve or precision dosing pump valve is used by a robot to apply adhesive to the protruding and already laminated material before folding.

Coating fabric/foil from roll to roll

Often, endless fabric, film, foam film, etc. is first coated with reactive adhesive on a coating stand before being vacuum or press laminated on separate systems. Directly linking the systems can sometimes be useful in order to obtain compact, self-contained systems.

Bead application for glueing of retainer / ledge

Depending on the number of pieces, bead and spray application is applied manually or by robot on retainers or intended gluing points on the carrier (e.g. environmentally friendly fibre composite carrier parts) and then joined together in the same way. balti has already supplied complete systems in this area, e.g. with rotary indexing table or partially monitored manual application. The latter e.g. with PUR system, multiple workstation, automatic switch-off of unused application stations, time help/alarms for operators glue application, joining time etc.

Laminating roller blinds / attaching labels

Compartments and storage areas, as well as their covers/lids, can be glued with hot melt adhesive. Whether it's just a handle, a label attached to a knob or ashtray with adhesive, or slats held together with a fabric connection and laminated with a hinge function to form roller blinds, balti can also offer complete concepts here.

Rear window assembly

Convertible tops are not only sewn together, but also glued at different places with hotmelt fabric and glass. balti not only supplies melting plants but also complete assembly cells for the application of glue and subsequent joining and pressing.

Rear window assembly of convertible folding top

Robot system for several vehicle types. Application of hotmelt on the rear window for folding fabric to fabric and for component assembly on the inside. In some cases 2K adhesives are also used for the latter. balti is also happy to integrate such systems, mostly from third party companies.

Car body sealing

Car body sealing / Sun roof modules

Butyl or special high-viscosity PUR adhesives are often used to seal car bodies or roof modules. The balti product segment covers such applications perfectly.

Headlight Assembly

Relatively large quantities of highly viscous and reactive PUR adhesives, with the dual function of bonding and sealing, are applied precisely into the grooves provided and then joined together to form the complete headlamp.

Headlights

From special tandem bag melters, a robot is used to produce uninterrupted and 3-layer headlight hoods with -housings, which are tightly bonded together. Process control is one of the top priorities in such applications.

Insulation

Mats and moulded parts made of fleece, foam, cotton or other natural fibres, are laminated and assembled with hotmelt. In many cases, non-reactivatable hotmelt, so-called pressure-sensitive adhesives or PSA (pressure-sensitive adhesive) are also only used as assembly aids.

Wheel-arch Insulation

Non-woven and foam mats are firmly bonded with a protective film or provided with a thin film as handling protection or, in some cases, only with a strip application.

Batteries

Also in the fast growing environment of battery production for e-mobility balti systems are used for bonding within the batteries as well as for sealing of housings.
