TRADE SHOW REVIEW 33 PET planet insider Vol. 13 No. 05/12 www.petpla.net Rotary bottle surface inspection system The Korean specialist for testing and surface inspec- tion displayed several machines on its booth, including the PS-21RP rotary surface inspection system for bottle sizes of 0.5 to 2.0l and a maximum capacity of 24,000bph. This rotary type of inspection machine rotates the PET bottle 360° to fully check for deficiencies during the PET bottle production by inspecting the mouth top crack, oval, sub- stances in & out, the sidewall and the bottom. In addition, the image grey scale of the CCD camera allows accurate filming and is able to detect unknown sur- face particles of 0.5mm at an accuracy of 99%. The system also collects data retrieved during the inspection process and enables monitoring of the data for statistical quality management. A self diagnostic feature that is installed in the system immediately alerts problems thus preventing failure of inspection. The mechanical structure of the system allows a 24/7 operation. Another version of inspec- tion systems, the PS-21RPL, is also able to detect pin holes starting from the size of 0.5mm. This system can handle 350ml to 1.5l bottles. In general, the company is also in a position to install inspection systems for bottom and sidewall in Sidel SBO blow moulding machines, as already realised in SBO10 and SBO16. www.pnstech.co.kr Y O U R PA R T N E R F O R B L O W M O U L D S .

PET STRETCH BLOW MOULDS Benef i t of 30 Years of Exper ience in Blow Mould Manufactur ing! Oil cap with changeable insert The Austrian company htw molds- and manufactur- ing technology specialises in the design and production of injection moulds for screw caps. The product portfo- lio includes soft drink caps, sport bottle caps, oil caps, flip-top caps, shampoo caps and cosmetic caps. 1-cavity pilot moulds as well as 96-cavity series moulds can be supplied. The company also holds patents on different kinds of screw caps and grants licences for production. The company also offers Toolstar hotrunner systems and gammaflux hotrunner controllers in connection with their moulds. At the exhibition different caps were shown, including a patented oil cap with a drop stop feature and changeable inserts for oil, soya or vinegar. www.htw-werkzeugbau.com Hydraulic PET preform system The Chinese company Hwamda exhibited and ran a PET injection system for the production of PET preforms combining a fully hydraulic injection moulding machine with toggle clamping unit, mould, robot (with drives from Lenze Germany) and auxil- iary machines. The M8-DH injection machine with single cylinder and servo motor has a two-stage injection unit in order to reduce the pre- plasticising cycle time and to shorten the whole moulding cycle time. It is also equipped with a two-circuit oil piping system and close-loop servo injection valve. The power system of the machine is all hydraulic and the main com- ponents are from brands such as Bosch, Intermot, Vickers, Yuken and Atos. www.hwamda.com
