Extruding solutions for PVC-m

The flexible Apollo system can be used in both multiplexed and simultaneous injection modes. The supporting software is industry proven for increased productivity, and is easy to use for small inspection scopes, while still having the power required for supporting large-scale inspections. The system’s lightweight design and digital capabilities are suited to simple, single person operations as well as applications where multiple testers and large data rooms are required. Its durability and portability make it suitable for applications such as ferrous and non- ferrous in-service tube testing and surface component testing. Additional features include full signal capture, configurability up to 1,024 channels and 256 frequencies, a wide frequency range of 1Hz to 10MHz, and automatic gain control.

Modified Poly Vinyl Chloride (MPVC) is a thermoplastic pipe and fittings material for use in applications such as water distribution, air distribution and mining. MPVC pipes

competitors’ machines, providing over 400 different screw geometries for 65 different models from the top extruder manufacturers in the world.

are a popular choice in Latin America and Oceania where large mining companies and exploration sites are located. Extruding PVC-m compound presents processing issues due to the requirements of additional energy input for proper plastification which is directly correlated to physical properties, such as toughness, impact and creep rupture regression, of the finished pipe.

 American Maplan offers over 400 different screw geometries

American Maplan has developed a specific screw design incorporating a special flight geometry that provides optimum plastification without sacrificing output rate or melt temperature increase due to shear. American Maplan manufactures single, twin-parallel, twin-conical and parallel extruders and offers screw designs for
