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.
