Production of Plastics Sheet Material

摘要

To produce plastics panels preset quantities of virgin plastics material, regrind plastic material and masterbatch are fed into an upper feed hopper 18 having an outlet door 19 operated by a ram 20. The material is delivered, on demand, from the upper hopper 18 into an intermediate hopper 21 with outlet clamshell doors 22, 23 which are rapidly opened and closed by fast acting rams 24 to deliver supply material into the main feed hopper 26. A constant supply of predictable quality mixed raw material is provided for extrusion to form panels.
