Once the part design was finalized, the participants needed to choose the parting line, gate locations and orientations. To up the challenge for Moldex3D in creating a robust process for the part, the parting line was placed around the base edge of the part, while the gate was located in the bottom corner, leaving the largest boss a relatively long distance from the start of flow — a scenario that can often result in sinks.

technotrans says climate protection, energy efficiency and customization will be key discussion topics at PTXPO as it displays its protemp flow 6 ultrasonic eco and the teco cs 90t 9.1 TCUs.

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

The companies settled on a complex part that could lead to defects if a good process was not utilized. The part design applied featured through-holes and ribs, with varying wall thicknesses — design aspects that can make defects such as weld lines, sink and hesitation highly possible.

To showcase the potential benefits of utilizing Moldex3D to apply simulation for the optimization of a tool design and process creation, the company created a test part design along with Fortify.

Dr. James Stern, HDPE Business Development Manager, North America, at ExxonMobil, commented: “This new product will be an ‘enabler’ for the value chain to create truly innovative solutions for blow-molded HDPE bottles and containers. Ongoing commercial tests and trials with converters and brand owners are proving highly successful, so we are confident about the interest this new solution will generate across the value chain.”

Injection molding simulation software has long been used to optimize a mold design prior to its fabrication. Now Moldex3D is working with additive manufacturing technology supplier Fortify to optimize the process that will be run on the printed tooling, maximizing its limited production run.

This is particularly useful when rapidly printed tooling is being used to expedite product design, and getting high quality parts in your hands quickly is the primary objective. As Moldex3D frames the situation: “For short-run quantities where defect-free parts are more important than a perfectly centered process, these starting parameters may be all you need.”

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

ExxonMobil has introduced a new Paxon HDPE grade that creates what the company calls a “paradigm shift” in properties normally associated with unimodal HDPE resins. Offering a “step change in environmental stress cracking resistance (ESCR) performance without compromising stiffness, impact, top load performance, or processability,” Paxon SP5504 is suited for household and industrial chemical (HIC) bottles and containers for bleach, wipes, agricultural chemicals, and similar products.

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

Moldex3D and Fortify acknowledge that under certain conditions hundreds and possibly thousands of parts could be molded from a printed tool, but it is much more common to mold 50 to 200 components from such a mold. The challenge of using a printed tool then becomes the fact that molding process development alone can take 10-20 shots before good parts come off the press. “When process development for a tool that is estimated to last 50 shots takes 20 shots to get a defect-free part, you are nearly 50% through the mold’s life before you have a representative part,” Moldex3D says.

In this collection of articles, two of the industry’s foremost authorities on screw design — Jim Frankand and Mark Spalding — offer their sage advice on screw design...what works, what doesn’t, and what to look for when things start going wrong.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

“Blow-molded HDPE parts typically contain PCR in the core of multi-layer bottles and containers,” said Mark Canright, Global Polyolefin Product Technology, ExxonMobil. “In California, for example, the current mandate for PCR content in blow-molded HDPE parts is 25%, and this is expected to rise in the next year. But adding PCR can impact the properties of virgin material, such as ESCR and top load. Paxon SP5504 enables converters to add even more PCR without significantly compromising the properties of the finished parts.”

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

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

This Knowledge Center provides an overview of the considerations needed to understand the purchase, operation, and maintenance of a process cooling system.

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.

Moldex3D’s Scott Sazin says that once the design was finalized, the mold files, molding resin (Vydyne 47HT nylon 6/6) and the machine parameters for the 30-ton Nissei NEX-IV were all sent to Moldex3D to perform its benchmark simulation. Moldex3D also considered the thermal properties of Fortify’s DT tooling resin, as well as the 30-second air blast to cool the face of the tools which is part of Fortify’s molding process. Moldex3D ran four different processes with varying fill times, choosing the one with shortest fill time and lowest residual stress, automatically generating a report for Fortify prior to it running the tool in the real world.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

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.

A 3D printing startup technology’s ability to evenly disperse functional additives to photopolymers and align reinforcing fibers within the resin during cure is drawing moldmaking interest.

With the industry driving toward increased recycling of post-consumer plastic waste, ExxonMobil has demonstrated value-in-use at PCR levels at and above 25%, which may help brand owners and converters to meet changing sustainability targets.

Fortify notes that the molding tenets typically applied to its molds call for low injection pressure and velocity, challenging the simulation software to completely fill the part without sinks or visible weld lines while remaining within the recommended process parameters.
