As a company, is your adoption of new technology passive and by accident or strategic and planned?
Responses to the annual survey are tracking well ahead of the previous year, and you still have time to complete your response and see how your facility stacks up.
When determining the best ejection option for a tool, molders must consider the ejector’s surface area, location and style.
Make your life easier by paying close attention to the procedural steps detailed in the test standards.
Here are answers to some frequently asked questions—and troubleshooting advice—to help you maintain your granulator blades.
Follow these detailed tips to get the jobs you want. This installment focuses on the mold and the molding machine.
An ever-growing number of sensors on injection molding machines provide real-time transparency into a press’s inner workings, but the low-tech sensors humans come with are still vital to keeping a plant running.

Let’s take the mystery out of rheology by showing how the wealth of information it provides can be used by processors to solve real-world production problems.
They are being specified more often for recycling applications to increase flexibility. But there is still no such thing as a GP screw and recyclers need to consider other processing approaches.
These articles garnered the most reader attention among stories posted in November 2020 by Plastics Technology: implementing automation, gauging residence time, the history of polymers and more.
What does it take to automate a horizontal injection molding cell to handle micro-sized inserts and molded parts? General-purpose top-entry robots and tooling may not be up to the job.
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.
There is no “one size fits all” solution in automation. When considering what it would look like in your plant, hone in on the staff, products, space, and goals that are specific to you and the automation system that you will be installing.
The blown film industry has evolved from monolayer film structures to multilayer ones for a variety of food and non-food packaging applications. Here are typical problems with these structures and tips on how to solve them.

Failing to calculate and accurately account for residence time can compromise material integrity before it’s even injected.
Save time and money by properly controlling the feed-throat temperature. In some cases—but not all—it can help you solve a bridging problem.
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.
Advances in downstream extrusion equipment have boosted production control.
Using a slit-die viscometer connected to a lab extruder can generate accurate data on melt viscosity at various shear rates and temperatures, a useful QC tool in processing.

Well-equipped and well-staffed testing lab elevates competence of custom processor.
When, where, how and why to use them.
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.
Metalworking shops and plastics plants make for interesting comparisons of their responses to the COVID-19 challenge.
Focus on six key metrics to help you determine when a process is lined out and stable enough to start production.
Statistical process control (SPC) can help plastics processors determine the factors responsible for product quality variation and provide a roadmap for improving the production process.
