Right: The new Allrounder Cube machine series is
designed for high-speed cube mould applications
injection moulding machine with a clamping force of 350 kN, equipped with a Euromap size 5 micro injection unit and a horizontal double-arm robot for the reliable separation of micro components and sprue. The micro injection unit combines an 18 or 15 mm screw for melting the material with an 8 mm screw for injection. This enables problem-free processing of normal granule sizes and therefore all common materials, as well as the first-in-first-out principle. At its Technology Days in March 2017 Arburg
Sven Kitzlinger, Application Engineering Medical Technology at Arburg
presented five applications and a variety of cleanroom concepts for the medical technology sector. A fully electric entry-level Allrounder 570 E Golden Electric used an 8-cavity mould to produce 20 mm PP syringe barrels with Luer lock threads in a cycle time of around ten seconds. Soft TPE caps to protect syringe needles were produced on a hybrid Allrounder 470 H with a 48-cavity hot-run- ner mould in a cycle time of around 18 seconds. A cost-efficient cleanroom concept was demon-
strated with an electric Allrounder 470 A. The high performance machine in light grey featured a clean air module above the clamping unit and uses FDA/ NSF-approved lubricants. It is docked to the cleanroom from outside by means of an extended conveyor belt with a tunnel cover. As only the clean parts produced are conveyed to the inside, the cleanroom can be operated very cost effectively. As a high-end injection moulding solution,
Arburg presented a GMP-compliant electric Allrounder 370 A in stainless steel for production in the cleanroom. This used PEEK (Vestakeep), which is approved for long-term implants, for example in facial surgery, orthopaedics and dental technology. Two 0.7 g ‘bone pins’ were produced in a cycle time of around 23s. The company says that the example
of facial and cranial bones showed how a Freeformer can be used to produce individualised implants from a resorbable medical polylactide (PLA). Sumitomo (SHI) Demag has supplied 50-tonne IntElect machines to Trend Technologies Ireland, a contract moulder of devices for the medical and life sciences sectors, for the company’s third ISO Class 7 cleanroom manufacturing facility. Trend’s capital investment in the facility and additional cleanroom space and equipment has enabled the company to boost process stability and achieve shorter production runs. Items moulded form part of Class I, IIA, IIB and III medical devices and include wound care products, diagnostic labora- tory consumables, ventilator housings, surgical handles and stent delivery sub-components. Trend says that most of these are highly customised, so when making the investment in new cleanroom machinery it focused on sourcing equipment that would automate process stability and increase product integrity. Dr Boy has adapted one of its injection mould- ing machines to enable a second blow moulding step to produce small bottles for pharmaceutical (and also cosmetics and food) applications. A Boy 60 E machine in a clean room design can, for example, produce bottles for eye drops.
