Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

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

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

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.

Milacron has filled the corners of its 26,600-square-foot NPE2024 booth with technology representative of its various fellow operating companies and preferred partner brands, including DME, FANUC Roboshot, Mold-Masters and its own injection molding machine line with the debut of its M Series. Milacron’s Andy Stirn says most prominent will be a 1,070-ton M-Series injection molding machine running a SyBridge Technologies 2-cavity tool for 5-gallon pails featuring in-mold label (IML) decoration and up to 50% recycled content via coinjection and a Mold-Masters valve-gated hot runner.

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.

The Mold-Masters hot runner controls are fully integrated into the Milacron’s injection molding machine control, with plans to utilize different resins and mixes of materials, including in different colors, to showcase how the coinjection technology can hide or reveal the core in a very controlled manner.

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

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.

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.

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.

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.

In a partnership with Kurz, Milacron is introducing its new M series two-platen servo-hydraulic machines. In a touch display application geared toward the automotive or appliance markets, Kurz-supplied decorative and functional foil is fed through the open tool for back molding. The 500-ton cell has three integrated robots, including one that enters the mold with an infrared heater used to heat the foil. Another robot removes the molded part from the press and places it on a fixture for trimming. The finished part is then moved to another fixture where it’s backlit to show the different patterns and buttons that are revealed as it is interacted with by consumers.

In a time where sustainability is no longer just a buzzword, the food and beverage packaging industry is required to be at the forefront of this innovation. By adopting circular packaging processes and solutions, producers can meet regulatory requirements while also satisfying consumer demand and enhancing brand reputation. Join Husky to learn more about the broader implications of the circular economy — as well as how leading brands are leveraging this opportunity to reduce costs, increase design flexibility and boost product differentiation. Agenda: The cost and operational benefits of embracing circularity Key materials in circular packaging — including rPET and emerging bioplastics How to design a circular food and beverage package Strategies for selecting sustainable closures to future-proof packaging solutions Optimization and streamlining of production processes for enhanced efficiency How Husky Technologies can enable your sustainable success

Stirn says the pail is a great application to utilize coinjection for sandwiching recycled content between layers of virgin resins, but there are others. While 5-gallon pails would normally run in cycle times of 18-25 seconds, Milacron is targeting 18- to 20- second cycles for the show display. “For coinjection, that is phenomenal,” Stirn says. “For a standard monolayer setup that’s competitive, to go that fast with coinjection of two pails is special.”

The German mould maker Klaucke & Meigies has been in business since 1994 and will celebrate its 30th anniversary next year. Starting in smaller rented premises, the company built its own production halls in a new industrial area at the turn of the millennium. From the outset, it has made sure that the industrial floors spotless and the machinery is always up to date. “When you walk into a production facility and see machines with that standard green industrial colour, then there is a need for investment. At our company, you only see such green machines in the grinding room,” says Managing Director Jan Meigies. “Our machines also impress the customers time and again.”

NPE2024: Coinjection of postconsumer resin, in-mold decoration, LSR micromolding and bioplastics processing are just some of the machine displays at Milacron's booth.

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

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.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Featuring twin injection units and a high-base machine design, the cell showcases the potential to free drop the buckets onto a conveyor running below the press, which is still common for many pail molders. Here, backside automation provides label insertion, with key stats on the label, as well as part removal and full inspection.

Another all-electric 275-ton Fanuc Roboshot is molding medical vials from a 48-cavity tool using a Mold-Masters hot runner system. Post-molding, a platen-mounted robot removes the 48 vials and places them on conveyor above the clamp, with the parts separated into “lanes.” Stirn says this setup helps “containerize” production for traceability while minimizing floor space impact.

Tool and mould maker Klaucke & Meigies has invested in new Sodick EDM machines. The purchase of the new machines will ensure fast processes and increased throughput despite a full order book.

A 55-ton all-electric Fanuc Roboshot with DIY Robots automation is set up for an LSR application in partnership with a cold-deck runnerless tool from M.R. Mold & Engineering and metering from Nexus to create very small umbrella-type diaphragms from a four-cavity tool. How small are the parts? Small enough that Milacron hasn’t been able to weigh them individually, but combined they weigh just 0.9g. Milacron turned to DME and its machining expertise to fabricate an 8-mm plunger system for the application to dose in material with precision. The positional accuracy of the plunger is due in no small part to the machine. “No machine controls motion like a Roboshot,” Stirn says.

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.

Klaucke & Meigies mainly builds plastic injection moulds and serves around 500 customers from a wide range of sectors, including the automotive and railway industries and pump manufacturers.

Milacron has three material partners for the project, with Shell supplying virgin HDPE for the skin and the core uses postconsumer resin (PCR) from KW Plastics and LyondellBasell that has been reclaimed, reprocessed and repelletized, with the PCR core to alternate each day between the two suppliers. To support this level of production, Milacron’s booth includes a 20-by-30-foot “Resin Room” with two 30-ton air-cooled chillers and a complete material handling system, including surge bins and vacuum pumps. Stirn notes that the company coinjected a pail at NPE2015, but it was from only a single-cavity mold running at 45-48% PCR core level.
