"Revolutionary" Device Makes Purging Safer, Simpler

By: Lilli Manolis Sherman 26. March 2015

What is said to be a “revolutionary” device designed to capture molten plastic purges and create a safer environment for personnel and equipment in plastic processing operations is being introduced at NPE2015 by the Dyna-Purge div. of Shuman Plastics.


            Lava-Shield is the result of a two-year development project and hundreds of rigorous field trials. This protective purge guard is said to be easy to use with a variety of processing equipment including injection molding, extrusion, compounding, blow molding and film of virgin and recycled materials. Field studies found that most purges were shot onto cardboard, or even worse, grabbed by hand with a hot glove or rag. Such operations always result in waste because the purge gets contaminated and has to be disposed of—aside from the injury potential to personnel.


            Designed with a unique combination of specialty papers, Lava-Shield absorbs and then dissipates heat quickly and will not hold or transfer heat. When the purge cools, the special non-stick surface releases the purge, free from contamination, The purges can then be recycled or sold for values. This protective purge guard is reusable up to five times, made in the U.S. with up to 30% recycled content and, can be recycled along with other plant and office waste paper.


            Says company president Ken Shuman, “Plastics purges are extremely hot and our clients challenged us to create a device that could take the heat in capturing the purges while also protecting employees and equipment. They wanted something that is safe to use, easy to customize, with quick release properties to keep purges clean…and it should be reusable and recyclable. We responded and are proud to introduce Lava-Shield, designed with plastics processors in mind to help them purge smart.”


            Lava-Shield is available in 150 count “full-brick” quantities, or 75 count “half-brick” quantities. A free sample is available for qualified applications.

Sabic expands its focus in additive manufacturing technology

By: Heather Caliendo 26. March 2015

Proof there is at least one guarantee in life: when you have a 3D-printed car at your booth, it’s going to generate quite the crowd. For instance, during NPE2015, Sabic (S-19001) is proudly displaying the Strati, the world’s first 3D-printed car. Using one of Sabic’s carbon fiber filled compounds, Local Motors was able to demonstrate the potential of additive manufacturing as a process technology that can shorten product development time, reduce prototype costs and enable greater design freedom.


And seeing the tremendous market potential, Sabic is expanding the company’s application development focus in additive manufacturing technology.


“We understand the need in the marketplace,” Tony Cerruti, marketing director of the Americas for Sabic told Plastics Technology. “The technology is opening up new capabilities, which is allowing the design freedom to create parts.”


Sabic says that its experience in additive manufacturing across a number of industries will enable it to work closely with technology innovators including universities, research laboratories, printer manufacturers, OEMs and emerging technology companies to help accelerate the advancements necessary for additive manufacturing to reach its full potential. Sabic’s investment in several industrial and desktop printers, including the Big Area Additive Manufacturing (BAAM) printer used to print the world’s first 3D-printed car, will help to facilitate process improvements in  fused deposition modeling (FDM) and other extrusion-based printing processes. 


Part teardown, concept creation, mechanical design, CAE analysis, material evaluation, part performance simulation, testing and advanced processing techniques are capabilities already in use at Sabic’s technology centers to serve multiple industries. For instance, in a recent project to search for innovation and efficiencies in luminaire design and production, Sabic used predictive engineering and 3D printing technology to create an integrated thermoplastic LED luminaire, highlighting the opportunity to reduce the number of parts by 84%, the total weight by 24% and assembly time by 65%, compared to a conventional metal luminaire.


Sabic offers a range of materials for use in additive manufacturing today including:


  • ULTEM 9085 resin most commonly used for aerospace applications. On display in Sabic’s booth is a 3D-printed economy class aircraft seat created as inspiration for future seat design and manufacturing methods.


  • LNP THERMOCOMP compounds – a carbon fiber reinforced material most recently used in the printing of Local Motors’ Strati vehicle.


  • CYCOLAC MG94 resin – an ABS material used by the maker community for fused filament fabrication (FFF) printing.


“We are showing real examples at our booth to help customers rethink how they might build a product,” Cerruti said. “Additive manufacturing is not just hype, the industry sees the potential.”


At NPE: 3D Printed Molds

By: Matthew H. Naitove 25. March 2015

At booth W2703, Milacron is showing several developments in tooling. One is a demonstration of how short-run injection mold core/cavity inserts can be built in-house on short notice using 3D printing. Milacron demonstrates this with a PolyJet sysem from Stratasys that inkjet prints droplets of thermosetting liquid photopolymer that solidify when exposed to UV light. Inserts were thus “grown” in 5 hr and loaded into a quick-change MUD mold base from DME, Madison Heights, Mich. (photo). The inserts last for about 500 shots.

AT NPE: Faster, More Compact Electric Press

By: Matthew H. Naitove 25. March 2015

The new Toyo Si-6 series of all-electric machines is one of three new developments being shown by Maruka USA, Pine Brook, N.J., at booth W303. Compared with Toyo’s Si-5 series, the new Si-6 series (pictured) is more compact, runs 33% faster, and has a redesigned clamp for easier maintenance. Larger models (the range is 55 to 1050 tons) also have redesigned injection units. The new System 600 controller runs 10X faster than the previous unit and offers added features. At the show, an Si-300-6 molded 32 plastic spoons in 4 sec, a full 2 sec faster than the previous model.


Maruka also showed Toyo’s compact, all-electric ET vertical machine, which now features enhanced controls for easier operation, faster response, and greater molding accuracy.


Two machines from Fu Chun Shin (FCS) of Taiwan were also on display. One was the new 160-ton FB-160 RSV hydraulic, two-material press. The other was the LA-SV series of two-platen hydraulic presses, brand-new to the U.S. and available in 550 to 4000 tons.

At NPE: Rotary Stretch-Blow Machine from China

By: Matthew H. Naitove 25. March 2015

Among the large contingent of Chinese machinery suppliers at the show this week, Tech-Long USA, Commerce, Calif., is showing off a new generation of rotary stretch-blow molders in booth S32001. The G5 model on display offers outputs up to 2400 bottles/hr per cavity with six to 32 cavities. It reportedly reduces energy use by 10-15% compared with previous machines and enhances compressed-air recovery by 40-55%. Improvements in speed result from use of servo motors instead of pneumatic stretch rods; an integrated gripper system for faster bottle discharge from the molds; and a new PLC with 15-in. touchscreen. Improved seals are said to reduce air-exhaust noise from 92 to 83 db. Keth Boss, CEO of Tech-Long Americas, says this is the fifth-generation machine from Guangzhou Tech-Long Packaging Machinery Co.
