This is an issue whenever you change jobs to a new mold with a different resin. Are the two resins compatible or do they react with one another? No matter how hard you try to purge the previous resin from the system, small amounts will remain on the screw flights. Purging compound may help, but even a small residual amount of the previous resin can provide a catalytic effect. For example, if you accidently mix acetal (POM) with PVC, you and the rest of the people on the shop floor will have an extremely unpleasant emotional and physical experience. Small amounts of either of these two resins catalyzes the decomposition of the other polymer to gases.

The consolidation press developed by Engel in cooperation with its partner Fill (Gurten, Austria) can be used to consolidate fiber stacks with deliberate fiber orientation and different wall thicknesses. All process steps are automated. All told, the consolidation process integrates inserting the fiber stack into the mould, transferring the closed mold to the heating press, heating, transferring the mold to the cooling press, consolidation, cooling and transferring to the initial station, where the mold is opened, the consolidated semi-finished product (blank) removed and a new fiber stack inserted so that the cycle can start again.

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.

Because of the growth of the plastics industry, there has been an uptick in number of new hires for processing plastics over the last few years. With new employees comes the challenge of training—not only on company policies and processing duties, but on safety. With that in mind, this column will focus on a topic I feel does not get sufficient attention. In fact, it is a topic on which most of us do not have all the details needed. In my experience, searches on the internet certainly proved inadequate. That topic is the mixing of different resins in the barrel, hot runners, and hot tips.

To be cost-effective in large-scale production, the stacks must be made and consolidated inline and within the cycle of the injection molding process. As a system supplier, Engel is in a position to offer integrated and fully automated solutions for the entire process – from individual tapes through to functionalisation in the injection moulding process – from a single source.

You will hear true stories of hoppers being blown to and through roofs, endcaps blown through walls, etc. The gases produced upon resin decomposition generate extreme pressures, which can and do blow injection molding machine barrels into shrapnel. The accompanying photo shows the front zone of a machine barrel that blew into pieces. Imagine the damage if it had hit someone! This may not happen often, but it does occur, and you need to be aware its possibility.

The processing and functionalization of thermoplastic continuous fiber-reinforced semi-finished products, such as thermoplastic fabrics or UD tapes, using the Engel organomelt process will be one key focus at Engel's trade fair stand this year at Composites Europe 2018. The world's first large-scale application has been launched in the US. Valeo Front End Modules manufactures front-end carriers with integrated air ducts for a renowned German OEM in Smyrna, Tennessee, believed to be Volkswagen in Chattanooga, Tennessee. In July of this year, the structural components won an Automotive Award from the Society of Plastics Engineers (SPE) for their innovative production based on organic sheets and its outstanding properties. The parts contain a high organic sheet fraction, resulting in significant weight savings and improved crash performance. In addition, it was possible to integrate the air ducts directly into the support using a double-shell structure.

Of course, safety in injection molding extends beyond material compatibility. High temperatures and pressures of 20,000 to 45,000 psi are needed to melt and inject plastic into complex shapes. While these machines are built robustly to handle these temperatures and pressures, it’s best take a serious look at the equipment on a regular basis and not assume all is OK. Do you review the machine/mold upon startup or during production to make sure these pressures and temperatures do not reach out and touch you or a coworker? For example, does the nozzle tip mate properly with the sprue bushing? Is a temperature zone overriding?

At Composites Europe 2018, Engel is setting a further milestone on the road to economical production of thermoplastic composites: The Engel organomelt process is being used for the first time world-wide in the large-scale production of front-end carriers with integrated air ducts.

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.

Determining the source of streaking or contamination in your molded parts is a critical step in perfecting your purging procedures ultimately saving you time and money.

Pick-and-place stacking technology with optical image processing offers highly flexible use. The tapes can have almost arbitrary widths and contours. Because the stacks obtain their shape required for the component during stacking, consolidation can be followed by forming and functionalisation in the injection moulding step without the need for intermediate trimming. Engel is already using this kind of solution for the manufacturing of its own products. The rotation arm of the e-pic robot consists of carbon fiber reinforced tapes.

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

Take a deep dive into all of the various aspects of part quoting to ensure you’ve got all the bases—as in costs—covered before preparing your customer’s quote for services.

The tape-stacking cell was developed by Engel. In order to achieve the shortest possible cycle times here too, it relies on the pick-and-place principle. This means that tapes can be deposited and spot-welded together at three-second intervals. Since the quality of the stack depends on the accuracy of the tape positioning, Engel has equipped the stacking cell with a measuring system comprising high-resolution camera technology. The measuring system delivers data that is used for actively intervening in the depositing process, thus guaranteeing the greatest possible depositing accuracy.

Two systems are used for the production of the blanks. A pick-and-place tape stacking cell with optical image processing and a consolidation press, which Engel will be presenting for the first time at Composites Europe. "With this new development, we have succeeded in consolidating stacks of fiber-reinforced thermoplastic tapes in the injection moulding cycle," says Dr. Norbert Müller, head of Engel’s center for lightweight composite technologies. "The consolidation press can be seamlessly integrated into the overall process, which significantly increases efficiency in the production of tailor-made tape solutions."

Baystar's Borstar technology is helping customers deliver better, more reliable production methods to greenhouse agriculture.

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

This reproducible thermoplastic approach enables integration of the forming process and functionalization, and to merge the supporting structure and functional elements in an adhesive manner. "The fully automated one-shot process contributes considerably to the low unit costs required by the automotive industry," emphasizes Christian Wolfsberger, Business Development Manager Composite Technologies at Engel's headquarters in Schwertberg, Austria. A further benefit: the exclusive use of thermoplastic polymers simplifies the development of recycling strategies with the aim of returning the components to the material cycles at the end of their service life. "We can see that thermoplastic-based composite lightweight design is increasingly becoming the focus of product developers, both in the automotive and aircraft industries," stresses Wolfsberger.
