polymer processing

Reifenhäuser supplied in 2005 a 35 m high 3-layer blown film line . Essential components of the new wide film extrusion line are: - gravimetric dosing system for each extruder, - 2 extruders, 150 mm screw diameter, - 1 extruder, 200 mm screw diameter, - 3-layer blown film die with internal bubble cooling and 2200 mm die diameter ensuring a high production capacity, - high-performance air ring KRF 2200, - film guiding system with 4 ultrasonic sensing arms, collapsing assembly and side gusseting unit, - 8-ply folding station for C-type folding enabling simple handling of the oversized film widths in greenhouse construction, - fully automatic short-length winder FAC 4200 with bobbin magazine, adjustable for winding different film lengths and to cope with extremely short reel changing cycles, - REIcofol automation system for process control, including film measuring station and indication of side gusseting depth. The new 3-layer blown film line is designed for an extremely high producti...

We would like to present the new series called Polish polymer processing companies . Firstly Zakłady Maszyn Chemicznych „METALCHEM” leading polymer extrusion machinery producer. Some information from the official web page below. Almost since the beginning of its independent existence Zakłady Maszyn Chemicznych „METALCHEM” have produced machines for the chemical industry, gradually increasing the share of plastics processing machines. At present extruders, extrusion lines as well as spare parts for these machines, including chiefly the plasticizing units account for 100% of production. Major events in the history of METALCHEM: Zakłady Maszyn Chemicznych „METALCHEM” Sp. z o.o (Chemical Machinery Plant „METALCHEM” Ltd) is a single-plant company located in the industrial district on the outskirts of Gliwice. The company is a direct legal successor of the state enterprise having the same name. 25.02.1951r. The Minister of Chemical Industry issues an order on establishing a state compa...

Just few words about 12th International Fair of Plastics Processing Plastpol which took place in Kielce, Poland 27-30 May, 2008. Sorry but there will be no sum up and statistics and even my own consideration the next time I will be prepared better. There are only two pictures of extrusion machines. The picture below presents machines from polish plastics machine manufacturer ZMCh Metalchem Gliwice one of it with high torque synchronous motor . PS. Have you visited Plastpol ? Please share your impressions.

This is a book which I do not have to recommend for people who are involved in the extrusion process. For those who are not just briefly one sentence. This book demonstrates how extrusion theory can be applied to actual extrusion problems such as screw design, die design, and troubleshooting . The recommendation can be the author achievements in the extrusion field in numbers of equations and patents.
