Injection Molding (May 01, 2009)
High performance machine for reduced cycle times
The new Allrounder H injection molding machine from Arburg is designed to combine high performance with energy-efficient drive technology, making it well-suited for thermoplastics processing with reduced cycle times.
The abbreviation “H” also stands for the machines’ hybrid drive concept: the powerful combination of electric and hydraulic machine components integrated in the Allrounder H.
The servo-electric clamping units originate from the electric Allrounder A series, and are complemented by hydraulic injection units from the Allrounder S advance. This combination is further enhanced by performance-adapted hydraulic accumulator technology.
Servo-electric drives optimize energy use, and offer up to 40 per cent in energy savings, because in addition to the servo-electric drive and braking energy recovery, the hydraulic accumulator is also driven with the minimum amount of installed pump capacity and by motors of efficiency class EFF1.

is introducing MonoPol, a new family of injection molding resins based on water-soluble polyvinyl alcohol, a safe, non-toxic, biodegradable polymer.
MonoPol can be used for various lost core applications where it can form a temporary structure around which other materials are formed. The water-soluble structure can then be dissolved away, leaving a hollow finished article.
The MonoPol family reflects the variety of formulations that are used to create films of differing performance. The material can be tuned to work at different fabrication speeds and different temperatures. Molding also allows structures to be customized by changing wall thickness and dimensional strength.
MonoPol is currently available in four different grades: ColdWater Soluble (from about 10C) to very Hot Water Soluble (above 70C). MonoPol is MoldFlow-certified and each grade is available in a full range of colours. Mechanical properties can be adjusted and customized for specific applications.
