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-Dual SIM GSM Advertising Terminal/GSM Machine Terminal for Election Campaign, 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,Wholesale Price Sc-Sc Duplex Fiber Optic Adapter, launched its first injection-blow machine, the first of a new all-GMP Certificated Halal Bitter Gourd Capsule for Weight Loss. 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).

4ton Mini Excavatorof Germany showed the newest version of its Pressblower system, a unique combination of injection and extrusion blow molding.

Hair Drier Mould Blow Dryer Mouldof 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.Coffee Grinder Accessories CNC Machinery Part. 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.
