UNICOR´s new corrugator highlight, the UC 1800, was supplied in 2007 for the first time. The machine supports mould blocks in metrical and imperial system thus permitting the simultaneous use of mould blocks of different lengths.

K 2007 was crowned with success for UNICOR presenting its products including the UC 1800 and the Compact Die Head to the world.

In 2006, after some new developments, UNICOR presented its new UC 1200. This machine allows for the production of pipes with 1,200 mm o. d. inclusive coupling in one production process.

Up to then cuffs had to be produced with injection moulding techniques. Especially for the production of cuffs up to 500 mm o. d. this process now can, investment cost saving, be transfered to UNICOR corrugators by the development of new mould blocks.

With a Management Buy Out (MBO) together with the NORDholding Unternehmensbeteiligungsgesellschaft mbH situated in Hannover, the UNICOR management has acquired the UNICOR GmbH Rahn Plastmaschinen from the UPONOR corporate group.

Members of the management:
Klaus Kaufmann (Managing Director), Ralf Mittermüller (Director Sales Dept.), Gerhard Häfner (Production Manager), Hubert Koßner (R&D Manager)

UNICOR passes the certification audit for the Quality Management System according to DIN EN ISO 9001:2000.

UNICORs success concerning large-size corrugators is documented by the 25th machine leaving the technical lab in Hassfurt. Innovative features such as the 1986 patented shuttle principle, the disc die head technology and the parking station as well as the experience lasting for decades strengthen UNICORs role as a market leader.

With its innovative UC 100 UNICOR could prove its change from a machine building company to a technology supplier. The high visitor interest on the fair showed that UNICOR corrugators exactly meets the requirements of the international markets.

for large-sized Corrugators

The first of the new middle sized Corrugator generation with revolutionized technology is presented during this symposium. The main characteristics of these corrugators are:

• pneumatic muscle
• clothoid curve
• cooling channel with looping effect in the forming blocks
• wear parts made of technical polymers
• separate vacuum and cooling channel

With the newly developed UC100, UNICOR starts a new machine generation for small and middle sized pipes.

New automatic coilers presented.

Specially suitable for:

• Multi-layer composite pipe
• PEX pipe

Specially suitable for:

• Corrugated pipe
• Smooth pipe

Inner and outer layer consist of two different materials: ideal for technical applications.

From October 25th to November 01st 2001 UNICOR successfully presents new technologies for corrugated pipe production at the K 2001 show and receives an international award from SolVin for PVC-innovations.

The UC1000 optimizes the production of double wall pipes in sizes ranging from 200 i.d. to 1,000 mm o.d.

The vario corrugator allows the adjustment of the chain length to the product length. Thereby, the highest possible efficiency in production and most economical utilization of raw material is achieved.

for the production of corrugated pipes from 3.0 mm i.d.

The world-wide largest MLC-pipe sizes 90 mm/110 mm are presented to the market. A product range from all in all 14 nominal sizes is available from now on.

Now: production speed 25 m/min!

The UC75 revolutionizes outputs: 30 m/min. of PE double wall pipe size 40 mm.

Extension of facilities for building large-sized corrugators in Hassfurt.

The founder of UNICOR, Dipl.-Ing. Horst Rahn, is honored for his achievements with the award "Entrepreneur of the Year".

In 1996, the "Special Award for Ecology and Innovation of the Bavarian Ministry of Economy, Traffic and Technology" is awarded to UNICOR.

UC250 revolutionizes the manufacture of double wall pipes of small and mid-sized diameters by using direct mould block cooling combined with vacuum forming.

UNICOR Extrusionstechnik Zella-Mehlis adds downstream equipment for soft profiles to its product range.

For the development of the Multi-Layer-Composite-Pipe with a diameter of 9 mm, the Innovation Award of the Federal State of Thuringia is granted.

DIN-ISO 9001 certification for Unicor Extrusionstechnik GmbH.

By using a new, closed cooling circuit for the direct mold block cooling with vacuum forming, a tremendous rise in output is achieved.

The MLC-pipe, consisting of an overlapped welded aluminum pipe with inner and outer layers of plastic, tightly bonded to the aluminum layer by means of a special adhesive, presents an innovation on the sanitary pipe market.

With the UC 850, UNICOR starts a new machine design for large-sized pipes which is still used today. The shuttle principle is going to stand its ground in corrugator construction over the years to come.

An own technology for the manufacture of MLCP lines is developed and the extrusion lines are built according to this concept.

After the fall of „The Iron Curtain“ UNICOR buys the "Suhler Maschinenfabrik" with a long tradition in building machines.

With the building and opening of own production halls the UNICOR concept was fulfilled.

The Shuttle technology opens up a new way for the economic production of large sized single and double wall pipes made of PE. PP and PVC by reducing the number of mould blocks required.

UNICOR means UNIversal CORrugator. Corrugators, i.e. machines for the manufacture of single, double and triple wall pipes, engineering, design, development as well as the sale of the corrugators are the beginning of a story of success.
