Plastic injection moulding, PVC extrusion type machinery are widely used in plastics industry. PE pellets, PP pellets, HDPE pellets, PVC powders, calsium carbonate, plastic compounds, regrinds can be transferred between different equipments within the production site. Powder, granular, flake, regrind or pellet type bulk solids are handled by conveying, mixing and dosing systems.

Process begins with bulk material loading to silos. Bulk materials within big bags, sacks or tanker trucks are conveyed to storage silos. They are weighed and transferred to mixers. After mixing plastic materials are transferred to injection moulding or plastic extrusion machinery. Central conveying systems are used instead of stand alone vacuum conveyors for large capacity plastic production factories.

Central plastics feeding system is used to feed PVC, PP, PE, HDPE type plastic materials to large number of injection moulding or extrusion machinery. Each machine has its own feeding hopper with built in level sensors. The central plastics feeding system monitors the product level in the hoppers and feeds the machine hoppers automatically.

Components of Plastic Injection Moulding and Extrusion Feeding Systems

Bulk Material Storage Silo: PVC, pp, pe granules, CaCo3, plastic compounds are stored in storage silos. PVC Plastic PP PE Compound Storage Silo
Pumping System: Supplies required conveying air for pneumatic conveying of plastics. PVC plastic granule pellet powder transfer pump

Control Panel: Used for controlling plastics handling systems. PLC controller is used in the system with PC based reporting functionality. PVC, polypropylene, polyethylene, plastic compounds, calcium carbonate, mixing, conveying, storage systems are controlled by intelligent software. PE PP PVC plastic handling system automation panel

PVC, Plastic Loading Unit: Used to feed the injection moulding and extrusion machinery. Special designed loading hoppers can be used individually or can be fed by central feeding unit at the same time. PVC Plastic Vacuum loaders central feeding system
