While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

Additionally, our team worked with a major plastics parts supplier where we helped overhaul their SMED program in order to further reduce changeover times. Upon arrival, we noticed all machines were equipped with magnetic platens (which makes quick bolt changes possible), and the changeover times were averaging over five hours, sometimes crossing shifts. Through analysis of internal and external operations, and moving internal activities to external ones, changeover times were reduced to less than one hour. The availability improvement also allowed the customer to bring back parts manufacturing that had been outsourced.

PT Tech Days is designed to provide a robust, curated, accessible platform through which plastics professionals can explore these trends, have direct access to subject-matter experts and develop strategies for applying solutions in their operations.

A good SMED quick changeover program can help optimize financial performance by converting non-value-add time into value-add time.

Adapting quick changeover tools to existing equipment can provide many improvement opportunities. Hydraulically driven and magnetic clamping system can shave several minutes per changeover, and they are safer and reduce maintenance costs. The system will eventually contribute to lower labor requirements since operators can now achieve what two or more maintenance technicians used to perform. And, there should be no wait time for the task.

The creator of the SMED concept, Shigeo Shingo, believed that changeover time can be reduced by 59/60th. And while I agree that this impressive level of improvement is possible, sustaining it can be exceedingly difficult and is often complicated by changes in the cadence of manufacturing operations. Re-balancing entire manufacturing lines may be required to effectively deliver and sustain SMED excellence.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Employee turnover and training shortfalls may create a wide range of performance issues on a single piece of equipment. Managers should analyze each changeover time. Are they consistent and indicate the process is being successfully repeated to achieve low variability in changeover times? Are these times consistent for each shift? If you do not have a solid training program and have granular performance monitoring, you can almost guarantee your changeover times will increase, which will cause chaos. Throughput velocities will be reduced, and work-in-process bottlenecks will result. The production quality and costs will soon be challenged. All too frequently, manufacturers do not recognize the symptoms until customer dissatisfaction occurs and financial penalties are assessed. To be successful, people require training and changeover times must be measured to ensure quick changeover value is sustained.

A homogenous melt is required for consistent part quality, but achieving it requires balancing a number of factors, including barrel usage and temperature as well as screw speed, backpressure and residence time. Learn how to prepare your melt for molding success in this two-part series.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

Economic swings bring previous expedient decisions to light. Machine and/or process restrictions degrade production velocity as equipment that was optimized for a certain product is put into service on another part and results in profit erosion. This is where a good SMED quick changeover program can help optimize financial performance by converting non-value-add time into value-add time. By using a toolbox full of SMED-specific methods in a robust process, and by leveraging SMED experts who bring both historical and state-of-the-art technical knowledge into the equation, will achieve the quickest possible changeover time.

When it comes to the internal setup time, there’s a huge human element in assessing the work.  The standards referenced must be fully understood in the context of the time the standard was developed compared to today. Controls, tools and the changeover process need to be continuously challenged to drive down the changeover time.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

While working for a Tier 1 automotive supplier, we performed a SMED activity to reduce the changeover times at a plant in India. Changeover times were reduced from three hours on average to consistently less than one hour. This was accomplished through internal and external changeover operation analysis and videotaping. This video analysis method identifies areas that create unnecessary or misplaced activities that can be moved and/or eliminated, resulting in a streamlined changeover process.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

In the plastics manufacturing industry, implementing Single Minute Exchange of Die (SMED) is known to reduce changeover times. It also creates value by optimizing activity against time—all while reducing waste. While SMED’s value may be increased or reduced by marketplace demand and therefore the need for optimum throughput, improving changeover can be done under any economic condition, including today’s COVID-19 crisis and recovery phases. I’ll go into detail on how to successfully implement SMED while sustaining it for a more profitable future of your plastics manufacturing plant.
