Company

Mr. Dipl.-Kaufmann Max Drossbach leaded the company through the difficult World War II years and exited a quick development in the post-war period. The original production line was mostly replaced by new, forward-looking and self-developed products. Mr. Max Drossbach actively participated up to his old age at the company's operation, which he designed and formed during his 40-years function. He was awarded with the golden citizen medal of the city Rain am Lech. The street in which DROSSBACH head office is located was named after him. Mr. Max Drossbach passed away January 1971 at the age of 81.

The first metal pipe is been mass-produced and thus the first metal pipe machine is launched. These metal pipes are mainly used as displacement pipe. Later will follow metal pipe for the applications chimney pipe repair, post-tensioning technology and ventilation.

The first corrugated plastic pipe machine DROSSBACH launched was the HD 25. This corrugator produces mainly PVC pipe from 7 to 25 mm / 1/4" -1". Later the materials PE and PP are added.

The development of the pipe technology is pursued very fast. The first mass-produced flexible PVC pipe is launched. This pipe took off its triumphal course as 'AGROFLEX', the leading drainage pipe for agricultural application.

A typical pipe laying of the AGROFLEX drainage pipe at about 1968.

With the HD 500-T1 it is for the first time possible to produce bigger pipe with diameters from 80 to 530 mm / 3" - 21". Nowadays still common features are already in this machine, such as a PLC control, a power lack emergency removal and a pipe forming with vacuum.

From the USA we got the task to produce a PVC sewage pipe up to ID 36" (ID 914.4 mm). The resulting HD 1200-T1 corrugator is the first machine world-wide, with circulating mold blocks in a shuttle conveyor and additionally is equipped with a parking station to produce various pipe lengths with socket.

According to the market requirements the development of the HD 250 corrugator is a chain of reasoning. As this machine is the ideal tools to produce cable protection and drainage pipe. The direct water cooling and the full vacuum system at the mold blocks and a mold block size adapted to the respective diameter result into a maximum production speed of up to 22 m/min / 72 ft./min.

At that time the biggest corrugator world-wide - the HD 1800 - for corrugated plastic pipe up to ID 1.500 mm (OD 1.800 mm) / ID 60" (OD 71"). Also in the matter of technique this machine is ahead of the times: Equipped with a parking station to produce pipe with socket in different length, centering ring to maintain the die gap between outer nozzle and mold blocks, a direct water cooling system for the mold blocks, emergency removal, automatic compensation of mold block height increment and a modem for remote maintenance, the HD 1800 is in the year 2001 the benchmark to produce biggest corrugated pipe.

The HD 500 corrugator receives a complete update. Direct water cooled master mold blocks with mold block inserts and a very high production speed up to 11 m/min / 36 ft./min identify the the new HD 500. This machine is already equipped with elastically supported inlet kurves, thus an afterwards adjusting of the mold block clearance during the heating up is not necessary anymore.

The product development of the SPF 450 S represents a quantum leap in the production of spiral metal pipe. The customers have with this machine all components in one machine frame, material decoiler, strip profiling unit and automatic cutter. The full computerized machine can be programmed for production batches and is working completely self-contained. Due to a multitude of setting options the adjustment and the diameter change is easy and quick.

The HD 1200 corrugator is been completely reworked in 2003. The master mold blocks and mold block inserts is installed in that machine, thus the change of diameter tools is getting quicker and easier. Additional these are now directly cooled with water for achieving a higher performance. The diameter range is now from ID 150 to ID 1000 mm (OD 1200 mm) / 6" to 39" (OD 48").
Furthermore the design of the machine HD 1200 is awarded.

At the end of year 2006 the construction of the new HD 1800-T2 corrugator is completed. With this machine the tool compatibility between the big size corrugators is consequently followed, here with the HD 1200 corrugator for the diameters from ID 500 to ID 800 mm / 20" - 32". As standard at DROSSBACH the HD 1800-T2 is equipped with a parking station to produce pipe in various lengths including socket and a modem for remote access.

The machine SPF 250 was presented for the first time at the DROSSBACH OpenHouse in 2007, which is specially developed to produce chimney pipe. This machine covers the main demand of chimney pipe from diameter 50 to 250 mm / 2" to 10", for flexible single and double wall pipe. Of course the SPF 250 is capable to produce flexible single and double wall ventilation pipe as well. Very fast this machine became the bestseller in the DROSSBACH metal pipe machine range.

The world's biggest cross die head extrudes a third material layer on a double layer pipe. This tool was developed at DROSSBACH within three years to enable a client with an extensive range of HD production lines to produce and sell a HDPE high-load pipe system for sewage application. The cross die head can be shift into the line on demand and improves pipe dimensions up to 1.800 mm OD / 71".

With the launch of the SR 300 DROSSBACH offers a universal machine for many fields of application. On this spiral pipe machine can be produced: post tensioning pipe from 25 to 300 mm / 1" - 12", flexible exhaust pipe for truck exhaust systems from 4" to 12", flexible single and double wall chimney liner and und flexible single and double wall ventilation duct from 2" to 12"

Since november 2012 DROSSBACH Maschinenbau GmbH, M.D.S. Meyer Gmbh and WPS - Water Pipe System GmbH are part of one group of companies. This provides synergies that benefits our customers throughout the entire value added process. These synergies give expertise in all facets of corrugated plastic pipe business, starting with design through manufacturing and commissioning the corrugators including lifetime service by DROSSBACH. For development, design and the choice of the ideal sealing system M.D.S. is your partner and finally the production and supply of corrugated pipe and fitting systems by WPS.

The development of the corrugator HD 800 is complete and this is presented to the plastics exhibition K-show 2013 in Dusseldorf.
As 'little sister' of the HD 1200 corrugator this machine contains the same advantages, a shuttle-system for the mold block circulation, a parking station to produce various pipe length with socket, master mold blocks and mold block inserts for a quick dimension tool change. By request there is a tool compatibility possible to the corrugators HD 500 and HD 1200.

DROSSBACH succeeded to develop a die head which allows 4 different material layers in the corrugated pipe. If allowed according to standards hence it is possible to produce a corrugated plastic pipe made of recycled material while the outer layer is made of very thin high quality material. This could save a lot of material costs. Also it is possible to save the expansive masterbatch, as only a very thin outer layer has to be done in coulor. This die head is suitable for the corrugators HD 500, HD 800 and HD 1200 and allows a production from ID 150 to ID 500 mm. Die heads for further diameters available on request.

There was the task to offer a small and economic machine to produce mainly chimney liner from 50 to 200 mm / 2" to 8". Based on the platform of the SR 200-T2 we developed the SPF COMPACT. This machine is reduzed to the bare essential minimum, without giving up the DROSSBACH-typical features. A material decoiler and an automatic cutter could be added optionally anytime.

Modular system enhanced!

Third generation of HD500 corrugated pipe machine.

The corrugator HD500-T3 comprises well proven engineering solutions implemented by DROSSBACH in 3-rd generation of big size machines.

What is new:

• State-of-the-art servodrives, no calibration needed during life time operations.
• A full automatic vacuum control and control of the process temperature and coolant flow,
• Very easy access to the mould block inserts for tool change and maintenance due to special doors on both sides of the corrugator and pneumatically openable roof.
• Electrically driven side adjustment of the corrugator with position memory for a very easy final tuning during production.
  

That all guarantees a reliable and trouble free lifetime pipe production.
