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-Compatible Front Print Backlit Pet Film 230 Rolls for Light Box, 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,Very Popular Super Clear BOPP Packing BOPP Adhesive Tape, launched its first injection-blow machine, the first of a new all-5 Star Hotel Pillow Top Royal Pocket Spring Mattress-Spring Mattress. 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).

Cast Iron Floor Gratingof Germany showed the newest version of its Pressblower system, a unique combination of injection and extrusion blow molding. Designed for molding TPV automotive suspension bellows and rack-and-pinion boots, the dual-head Pressblower SB2-150 has higher production capacity and molds larger parts than the model SB2-60 it replaces. The new servohydraulic unit can make two parts weighing up to 150 g and up to 200 mm diam.

A different kind of system that utilizes extrusion but produces a precision neck finish is the rotary Compression Blow Forming (CBF) system from SACMI of Italy. Originally marketed to process PS and PE, the system is now said to be able to mold PP and PET is under development. Stretch rods can be added to the basic process. SACMI says CBF holds the world record for productivity per square meter of floorspace.

Extrusion Blow Big & Small

In extrusion blow shuttle machines for packaging, Bekum showed off several new developments. One was the prototype of a new all-5 Star Hotel Pillow Top Royal Pocket Spring Mattress-Spring Mattress, called the Concept 808 (see September Keeping Up). It has a clean new look, new control system, large 24-in. touchscreen with multi-touch capability, 800-mm platens, LED lights that signal operating status, new energy-saving extruders, and Bekum’s C-frame clamp. The new Bekum Control 8.0 is described as “Industry 4.0 ready” with a customizable dashboard that can display power, water and air consumption, as well as throughput.2MP Smoke Detector Alarm Ahd Cvi Tvi CVBS 4 in 1 Hybrid Analog Mini Covert Hidden  Camera with Fixed or Pinhole Lens.

Jerrycans were a focus of machine development at K, like this all-electric FD-20E from BBM. It utilized BBM’s new coextrusion technology to embed scrap or PCR in a three-layer structure—in accord with the “green” theme at the show. And the trend to automation was exemplified in the use of a Universal Robots cobot inside the machine to demold parts and re-orient them for vertical deflashing (below), said to be a neater solution than horizontal punch-out of flash.

1278 650ml Factory Supplied Disposable Wide Mouth Glass Mason Jarshowed its largest shuttle machine, the model 900, equipped for EPET. Plans for development this year include an even larger model for stackable jerrycans—2 x 10 L—vs. a maximum product size of 5 L currently. Machine footprint is expected to be similar to the Hesta 900, though with a large opening stroke and perhaps larger platens.

It has 55-ton clamps and 1-meter stroke. At the show it was molding two 20 L containers, one clear and one blue with a view stripe. 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.

Carbon Fiber TPU Case for Huawei Honor Play 7X/Enjoy 7sof 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.China Supplier Wholesale Italian Import Modern Style 12 Inch Deep Bathroom Vanity. 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.

Two machines were shown byAluminium Window/Door/Curtain Wall Aluminum/Aluminium Extusion Profiles From Chinaof Italy.

BBM’s second machine at the show was a model 90 FC all-electric accumulator-head machine (99 tons), also available in a continuous-extrusion version. It’s aimed at technical parts or drums up to 250 L. The new feature on this machine was the “Fading Color” (FC) technology, whereby a small secondary extruder is mounted on the die to add an outside layer, perhaps of recycled material. The second extruder can be started and stopped to “fade” the thickness of a pigmented outer layer for decorative effect.

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,Wooden Handle Carbon Steel Axe, 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.
