More than 45 years of experience make Gerlach unique

From the beginning the product is the focus…

Elastic profiles, mostly made of a rubber material, more and more also of silicone, are our daily companions, without us perceiving or even seeing them properly! But they play a key role in many applications: they seal windows and doors in our homes and cars, for example. They ensure that our environment remains comfortable, warm and dry. They are made of natural or synthetic rubber and must be vulcanized to be permanently elastic. Exactly this process is carried out in the vulcanization plants of GERLACH Maschinenbau.

We, Gerlach Maschinenbau GmbH, are the worldwide technology leader in continuous hot air vulcanization. Our customers receive from us tailor-made systems according to their individual ideas – always adapted to the requirements of the final product.

The various vulcanization and drying channels from Gerlach

In addition to hot air, Gerlach also uses other energy sources in the vulcanization and drying ducts with exhaust air cleaning. These include in particular microwave and infrared energy as well as a process-specific combination of these with the hot air. In addition to vulcanization, the cooling of the extrudate and the profile pull-off are an essential part of the extrusion process. Gerlach Maschinenbau also builds and supplies these machines. Depending on the requirements of the customer from the automotive, facade construction, water/waste water treatment, hose production or various other branches of industry, Gerlach’s delivery program includes the individual machine as well as the fully equipped production line for the entire extrusion and vulcanization process at the customer’s site.

The technological “know-how” paired with the excellent mechanical engineering, in execution and quality, have for many years been a guarantee for an efficient and successful rubber vulcanization for our worldwide operating customers.

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.
