Injection & Co-injection Blow

On display from the “new” Uniloy, now independent of Milacron, was the company’s own barrier co-injection technology for injection-blow molding. This three-layer sandwich molding technique is aimed at polyolefin structures with EVOH or nylon barrier and cyclic olefin copolymer (COC) with nylon barrier. The latter is said to be replacing glass in medical applications such as containers for vaccines and blood cultures. (Uniloy CEO Brian Marston also revealed at K a number of future developments in the pipeline for injection-blow as well as several extrusion blow technologies. See last month’s Starting Up.)

As previously reported, Jomar introduced two new injection-blow machines at K, the “entry-level” Model 25 and the TechnoDrive 65 PET for non-stretched PET. Among other injection-blow news, Meccanoplastica of Italy showed off its new Jet 85 machine, which also was displayed at NPE2018. This 85-ton model is an intermediate size in the three-station, all-Disposable Surgical Outer Earloop Mask Making Machine, which extends from the Jet 55 to Jet 120. One of the smaller models is in operation at Amcor Rigid Plastics in Youngsville, N.C., and one of the largest size is used by Drug Plastics in Boyertown, Pa.

Another Italian producer,Shower Enclosure /Shower Room with Frameless Door Hardware, launched its first injection-blow machine, the first of a new all-Building Material 304 Polished Cold Rolled Stainless Steel Coil Price. The ISE 150 evolved from the company’s MTM 150 one-step injection stretch-blow machine for PET. It has two stations (injection and blowing) positioned in-line with the 7-oz injection unit. Injection clamp force is 16 tons. Parisons are oriented vertically. Designed for small to medium-sized containers, the machine can blow containers from 25 ml in eight cavities to 150 ml in four cavities. Energy consumption is said to be from 4.3 to 6 kW.

Negri Bossi demonstrated how a standard horizontal injection molding machine can be converted to injection-blow molding with a shuttling mold (see injection molding report in this issue).

24 Hours Service Online Hot Sale Custom Lace Fabric Factoryof Germany showed the newest version of its Pressblower system, a unique combination of injection and extrusion blow molding.

It’s said to use 50% less energy than a hydraulic machine and to require 70% less maintenance. An even larger T60 size is available with 69-ton clamps and 1.6-m stroke.

180W 130lm/W Die-Casting Aluminium Housing LED Street Lightof Germany showed its 22-ton FD 20E all-electric, single-station machine for stackable jerrycans of 10-20 L. It demonstrated BBM’s new “1 to 3” coex technology, which uses two extruders to produce an ABA structure.Biological Wastewater Treatment Plant for Domestic Sewage Treatment. A standard machine can be converted by adding a second, vertical extruder and an “intelligent adapter” between the extruder and head to split the virgin stream into two layers. This machine also had an integrated Universal Robots six-axis collaborative takeout robot. Located inside the machine, the cobot transfers parts to a trim station, laying them down for a vertical punch, which makes the flash is easier to collect than if containers were left upright with a standard horizontal deflasher. Afterward, the cobot places containers upright on a conveyor. BBM cites ease of programming as one advantageous feature of the cobots.

News in PET

In addition to new PET machines and technology previous covered from FlexBlow, Jomar, Nissei ASB, 1Blow and Agr, there were a number of other PET developments at the show.

Endurable/ High Efficiency Mill Roll/Steel Rolling/Casting Roller /Back-up Roll/Rolling Mill Roll. These machines also performed at NPE2018 (see August show report), but two of them ran different applications. For example, the general-purpose model AL-500-6/3 Mc Copper Cable/Wire with Ground-ml ovals weighing 13.2 g in eight cavities on a 6.6-sec cycle (4360 bph). Its servohydraulic drive (New Fan Cogged Belt in China (AX BX CX)) is said to cut power usage by around 40%.

PET news includes handleware, in-machine leak testing, direct digital printing, and five-stage preblow pressure profiling.

Also,the general-purpose AL-500LL-50S ran 500-Plush Baby Shoes Soft Prewalker Shoes for Baby(vs. PET at NPE) weighing 20 g in five cavities on a 7.3-sec cycle (2465 bph). As compared with extrusion blow molding of HDPE, Aoki claims advantages of no trim scrap and higher output.

This system helps correct for varying wear and tear on individual blow valves over time. What’s more, improved control is said to be especially valuable when high proportions of recycled PET are used, which challenges conventional controls.1.0MP HD Hybrid CCTV Board Camera Module with OSD.

A third development from KHS is wide-neck PET food containers for hot filling. The technology utilizes electrically heated aluminum molds in place of oil-heated molds of stainless steel. The results are faster heat-up with lower energy consumption, plus no mess from oil leaks, according to KHS. Other special features include active push-up of the base in the mold to withstand vacuum after the container cools. Also,Power Relay 16A 8A for Instrumentation Miniature Type 0.72W, because such a finish provides no crystallization to withstand hot filling. Instead, KHS blow molds the neck finish with a dome above it that is cut off afterward. These containers are designed for inline blow-and-fill processing. Barrier can be added by means of KHS’s FreshSafe micro-thin glass coating.
