Frigel Firenze: New standards for cooling and temperature control

Friday, July 20th, 2001

Frigel Firenze S.r.l., 40 years long experience in plastic processing field, is able to introduce into the market new and revolutionary machines:

It is a machine for air cooling of blow film extrusion process.
In fact, cooling of the air in film production process is the key factor for:
- production increase (up to 20 %)
- 30 % energy saving if compared with a traditional system
- better and stable product quality
- higher brightness and transparency of the film
- max. productivity 24 h on 24
The company developed its own control allowing the machine reaching lower working temperature (very close to 0°C).

HT AG: Expansion of production into Russia

Friday, July 20th, 2001

European PVC window profile leader HT Troplast AG, Germany, which bought the financially ailing German profile extruder Gebrüder Kömmerling Kunststoffwerke GmbH in October, has expanded production into Russia and started up a major in-house PVC compounding line at its KBE window profile plant in Berlin.

Koch-Glitsch: First Presentation at K 2001

Thursday, July 19th, 2001

Koch-Glitsch, an American based company with subsidiaries in several countries of Europe, presents the first time at K’2001 their static mixing and reaction equipment for polymer production and processing.
With a novel type of flow model the mixing efficiency of the SMX and SMXL mixing elements at laminar flow conditions is demonstrated using a viscous fluid.

The new developed mixing nozzle KMH-KSM for injection moulding machines is presented. It is homogenising the melt during the injection process at 30 to 50% lower pressure drop as compared with earlier designs. The nozzle can be disassembled completely in its individual parts and can be easily cleaned or checked. A system of notches assures always the correct assembling of the unit.

For homogeneous melts in extrusion melt blenders in two different versions are shown based on the well proven SMX mixing elements. With the type KMB-S they are installed in a sleeve whereas with the type KMB-R the elements are welded to a rod an equipped on one end with a support ring. Both versions will be placed in the flow channel of the melt just upstream the die.

For the polymer production several products will be presented. Mixer heat-exchangers for viscous, temperature sensitive polymer solutions or polymer melts are exhibited. SMXL or KHT mixer packing, installed into the pipes of shell and tube heat exchangers do improve the heat transfer coefficient by factor 5 to 6. Contrary to the shell and tube heat exchangers in the SMR mixing reactor shown the product is flowing around the pipes. The SMR is used as reactor for polymerisation reactions or in general for cooling and heating of viscous fluids. The SMX polymer mixer is successfully proven for admixing low viscous additives or colour pigments to the polymer melt just upstream the garanulation system.

Thatcher Tubes: New production facility

Thursday, July 19th, 2001

Thatcher Tubes LLC,USA, is expanding plastic tube production capacity at its plant in Woodstock. Thatcher will build a 30,000-square-foot addition that will house additional extrusion lines and boost warehouse space. The firm expects to complete the project by the first quarter of next year.

Fischer of Staffhausen bought a 15 percent stake in Kirn, Germany-based Simona, which makes semi-finished products such as sheet and rod, as well as pipe, molded parts and fittings.

Egeplast: 40.000 tons PE pipes in year 2000

Tuesday, July 17th, 2001

The world-largest manufacturer of PE pipes, Egeplast Werner Strumann GmbH & Co KG in Germany, has produced approx. 40.000 tons in the year 2000. The German market amounts to 230.000 tons, a growth of 5 per cent p.a. With 140 employees Egeplast achieved a turnover of EURO 57 million last year.

UNICOR: New corrugator generation

Monday, July 16th, 2001

More and more (so-called technical) pipes for technical and industrial applications, such as for automotive industry, medical applications etc. are produced on corrugators. Standard corrugators confront the manufacturer with the problem of the fixed (= non-variable) chain lengths. These fixed chain lengths very often mean that a certain, not negligible quantity of non-usable product (waste) is produced, because the fixed chain length does not take into account the specific product length.

In order to overcome this inconvenience, UNICOR GmbH Rahn Plastmaschinen, has launched two new corrugator generations. The (traditional) corrugator models UC 15 and UC 58 have become “variable” in chain length. This means that the chain length of the corrugator can be extended in steps of one mould block length in order to meet the required product length, thus avoiding costly waste. This variability of the chain length allows the manufacturer to choose e.g. a chain length of 46 moulds for product A and 63 moulds for product B on the very same corrugator. As the construction of the corrugator is based on the construction set principle, the change-over time needed from one chain length to the other is very short.

Rauwendaal & Paulson Training: Extrusion Training

Monday, July 16th, 2001

New interactive training programs for extrusion are planned by a new partnership of Rauwendaal Extrusion Engineering and Paulson Training Programs, USA. Both firms will also jointly offer each other’s current interactive extrusion training programs, which range from basic operator training to advanced engineering. Future courses to be developed jointly will include Statistical Process Control in Extrusion, Troubleshooting the Extrusion Process and Extrusion Downstream Equipment. The troubleshooting program is expected to be the first to be released.

Jana Labs: Buying of Pipe Testing Business

Thursday, July 12th, 2001

Jana Laboratories, USA, has purchased the pipe-testing business of Specialized Technology Resources (STR).STR has had over 30 years of pipe- testing experience. Jana Labs specializes in chemical-resistance and burst testing of plastic pipe. The merged business reportedly will be the largest independent test laboratory for plastic piping systems in North America.
