The requirements placed on plasticizing units are continuing to grow. “This is driven, among other things, by the on-going substitution of traditional technical materials, which generates considerable increases in the performance of polymer materials,” reports Günther Klammer, head of the Plasticising Systems division at Engel. “We ensure that even new materials can be processed even faster and to even higher quality standards despite what are in part increasing stresses on mechanical components.” The keys to this are, on the one hand, continuous investment in new machining technologies and, on the other, splitting the screw portfolio in order to offer the best possible solution for every material execution.

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.

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

New designs of medical device components demand a higher level of testing and scrutiny due to the critical nature of their uses and the potential consequences of failure. In health care settings, a malfunctioning device can have life-threatening implications. Rigorous testing is essential to de-risk new designs by ensuring that components function safely and effectively. For this testing to provide meaningful results, the parts need to be representative of production parts. Investment in a steel production tool can be a risky decision point for a product developer, putting leaders in the position of committing to a design that may later need to be changed based on verification and validation test results.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

Long glass-fiber reinforced polypropylene and polyamide are commonly used for lightweight automotive construction – above all when high impact strength, excellent impact behaviour and low weight are required. The processing challenge in injection molding is to keep the fiber as long as possible and ensure uniform distribution of the fibers in the melt.

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

August 29-30 in Minneapolis all things injection molding and moldmaking will be happening at the Hyatt Regency — check out who’s speaking on what topics today.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

“Because errors discovered after we have sourced our metal tooling are expensive and time-consuming to fix, freeform injection molding allows us to replace the binary ‘invest-before-you-can-test’ paradigm of metal tooling with a gradual migration from prototyping that promotes a much higher decision quality, along with lower costs, shorter lead times — and happier development teams,” Staal says.

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

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.

Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

New system automatically cleans mold-cooling lines—including conformal channels—removing rust and calcium, among other deposits, while simultaneously testing for leaks, measuring flow rate and applying rust inhibitor.

This month’s resin pricing report includes PT’s quarterly check-in on select engineering resins, including nylon 6 and 66.

The previous solution was a single flighted 3-zone screw with a bolt-on long glass-fiber (LGF) mixing head. With the demand for injection molding machines for processing long glass fiber-reinforced plastic in rod granule form on the rise, Engel decided to manufacture the screw and mixing head from a single piece and to further optimise the screw geometry. The newly developed LFS offers maximum plasticizing consistency when processing rod granules and reduces fiber breakage. In order to ensure superior distribution of the fiber bundles in the product, the screw geometry was also optimised. Highly effective flight-welding gives the screw the required wear- and corrosion-resistance.

The FIM process starts with a 3D printed mold, its design is the inverse of the desired part and printed from Nexa3D’s xMOLD resin. Once the mold has been printed and assembled, it is placed in a mold base in the injection molding machine. The mold base may be a simple metal plate or a more elaborate master unit die, depending on the application. Material is injected into the cavity to form the part, and the cavity and part are ejected from the mold base to cool. The tooling is compatible with standard injection molding machines, and no special modifications are required.

The flexibility, biocompatibility and stability of silicone make it an essential material for medical device components. However, these components can be challenging to prototype. Thermoset materials such as silicone cannot be melted and built up the way a thermoplastic material can be. There are ways of printing silicone parts, but the results are not as precise and not comparable to injection molded parts. Precision is especially important for medical device assemblies, such as those made by SPT Vilecon.

According to SPT Vilecon CEO Bjarne Andersen, FIM saves customers both time and money. By getting testing done faster and on prototypes made with the right materials, Vilecon can get a design to a “fast fail” or to market sooner — whichever the case may be — thus shortening the time before a product starts generating revenue.

SPT Vilecon, a development and manufacturing services provider in the medical device and pharmaceutical industries, has implemented a prototyping process that de-risks and accelerates the development process by going directly to a representative, injection molded part. Without creating a steel tool. The process is Nexa3D’s freeform injection molding technology (FIM), which uses additive manufacturing to create single-use, dissolvable injection molds.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

The mold and part are then placed in Nexa3D’s xWASH-FIM device. In the washing chamber, the resin is dissolved in solvent, leaving the finished part behind. Besides getting to an injection molded part more quickly, the process also removes some geometric constraints on molding that can require additional tooling in other situations. Unlike a traditional mold, a dissolvable mold does not have to release the part after injection.
