Consulting & Planning

In addition to plant equipment, the selection of the right mixtures of materials plays a major role in the quality of the final product. By working closely with different manufacturers, we are able to test your mixtures on our extruder plants and subsequently perform common optimisation. Finally we will advise you on the vulcanization process for your production line and provide you with detailed information about the surface structure, the quality and the calculated production time of the final product.


The process technology is one of our most important core components and reason for the high efficiency of the GERLACH industrial engineering. Through close cooperation with scientific institutions, we are always working on further optimisation and refinement of the mode of operation. In addition, we provide you with support with the design of your vulcanization line with our many years of experience. With the aid of our partners, we configure the industrial engineering components to optimally adapt to your application.

The acquisition of machinery is always an investment that must be calculated and prepared. Particularly for special-purpose machines, many financial institutions have difficulties in assessing the value and classification of the assets. For this reason, we have been working closely with well-known financing service providers for many years and we are happy to arrange suitable contacts. No matter whether it is leasing, financing or price-sharing – we will find a tailor-made solution together with the appropriate credit institutions.

Hot air shock channel type 111

With the diverse options of our hot-air shock channel type 111, we offer a compact and flexible unit. By using special materials, shock temperatures of up to 550 °C can be generated. The accelerated hot air flowing turbulently in the duct generates the fastest possible heat transfer. For further performance improvement, all our pre-shock variants can be optionally added.

Cooling channel type 179

Specially designed surge nozzles characterize our cooling channel type K179. Even in extremely polluted and calcareous water, the cooling function is maintained by the permanent water flow. Additional stowages allow the profile to be submerged and guarantee good heat dissipation. The built-in blow-off stations with rigid and flexible nozzle systems ensure perfect drying even for complicated profiles. The use of heat exchangers for connecting existing cooling systems is self-evident.

SHF 147

With the integrated exhaust air purification (PCT) and the tried and tested recirculation system, the SHF 147 shock channel is an efficient high-performance system. Designed for high production speeds, this plant technology is predominantly used in automotive profile extrusion. The modular construction in 3 m zones consisting of shock, microwave and hot air zones is supplemented by additional options, such as selective profile transport via driven rollers or conveyor belt, as well as other additional functions. As a result, you get a smooth and matte profile surface, fine cell structure with moss rubber, as well as fast solidification of the profile geometry.

Pre-shock type P 158

Through the use of special short-wave infrared radiators, excellent profile surfaces as well as early dimensional stability with solid and moss rubber products are achieved. Characteristic for this machine is the radiator arrangement in four different planes and thereby a selective possibility of the 360 ° pre-crosslinking of the product. The machine equipment and very good power modulation, in the range 0 – 100%, enable high flexibility in production operation. For the support of the profile, removable guide rollers can be used with the possibility of an axial distance adjustment depending on the profile sag. The IR radiators are protected in all levels by special glass panes and the integrated cooling also ensures an increase in the service life.
