Buyer's guides, process explainers and industry news for anyone specifying plastic recycling and extrusion equipment — how shredders, washing lines and pelletizing lines are configured around a given feedstock, and which plastics can realistically be recycled at scale.
26 Jul After the die, pipe and profile are still soft enough to deform. A vacuum calibration table holds them to size while cooling water sets the shape. This guide covers how vacuum and cooling work together, how a calibration table differs from a sizing tank, and what goes wrong when tooling or alignment is off.

26 Jul Single screw extruders move a stable melt at steady output. Twin screw adds real mixing, venting and control over heat-sensitive material like PVC. This guide covers how each one works, which materials suit which, and what the choice means for pipe, profile, compounding and recycling lines.

26 Jul Granulators, shredders and crushers all cut plastic down, but they take different feed and leave different output. This guide covers what each machine does, how cutting action and screen size decide the result, when one stage is enough, and how the choice affects downstream washing, extrusion or pelletizing.
