Modular 'Plant' Brings HPDE Pipe Extrusion to Site
Modular sytems can extrude 4- to 26-in. pipe and has capability up to 48 in. in lengths of 500 ft or more.
Troubleshooting Pressure Fluctuations in Piston-Type Melt Filters
Piston filtration offers many advantages over other systems. While pressure fluctuations could be regarded as their weakness, there are many ways to avoid them, both from the mechanical and the process side. Small adjustment can make a huge difference in the overall performance and efficiency of the system.

Optimizing the Effective Life of Screws and Barrels
By adopting a few relatively simple practices, plastics processors can extend the life of the vital components of their plasticating unit. Here’s how to get started.
When to 'Adapt,' When to Retool?
That is the question pipe and tubing processors typically confront when they specify a line for one product, only to have to add to the product mix when business conditions change. Here are some tips to guide you to the right answer.
Materials Knowledge Pays Off at Teel Plastics
Well-equipped and well-staffed testing lab elevates competence of custom processor.
Fast, Precise Machine Helps Tubing Processor Make the Cut
Instead of turning down a job or farming out cutting to another company because of downstream bottlenecks, Eagle Elastomer can now handle all extrusion process functions in-house.
PPEs Are Here to Stay: Is Your Sheet Line Ready?

Israeli Pipe Processor Adds Potent Single-Screw Extruder
Billed as ideal for large-diam. pipes, new extruder provides processor with higher output and better quality while consuming less power.
Extrusion: Solving Surging in Two-Stage Screws
This usually crops up when the two stages are not matched in output. The best solution is to install a pressure-adjusting valve at the discharge end of the extruder.
Extrusion: Go from Fluff to Blown Film With Twin-Screw System
System bypasses pelletizing step and can reprocess barrier films.
Shopping for a Barrel? Consider the Full Cost of Ownership
Beyond just the “invoice price” of a barrel, processors should consider factors like the composition of the inlay, quality of the backing material, straightness, concentricity, machining imperfections and packaging/handling, to understand the true cost of owning a barrel.
