The latest edition of the huge annual plastics show returns to Guangzhou. Here, we preview some of the highlights that are of interest to film and sheet extruders
Chinaplas 2017: exhibition preview
Chinaplas returns to Guangzhou again this year. And, despite a slight increase in exhibition area space to around 250,000 sq m, the organiser, Adsale, is expecting exhibitor numbers to be flat – and visitor numbers to fall by around 7% (though this is compared with the Shangai version of the show).
The show is expected to host around 3,300
exhibiting companies. Here, we round up just a small selection of the technologies of interest to film and sheet extruders. Amut Comi will showcase a working ACF 820
thermoforming machine at Chinaplas. The model is configured in three stations (forming -
cutting - stacking), with a forming mould size of 820 x 650mm and clamping force of 240kN. The cutting station has area of 800 x 630mm and clamping force of 600kN. The heating oven is a new development with five-step
length or 3.250mm, and allows thick PP sheets to be processed without any need of pre-heater. Visitors will see the machine deliver PET punnets starting from 350 micron foil and reach a production speed up to 60 wet cycles per minute with a 15-cavity mould. All the company’s thermoforming machines are
driven by Easy – the smart HDMI that understands the data set by the operator. Its main feature include: automatic adjustment of cycle parameters, based on the set speed; optimised diagnostics; monitor displaying of I/O PLC cards; automatic check of the set parameters – refusing data that is not compatible with the prede- fined cycle; detailed pie chart of all functions of the automatic loop; and, an energy saving system with optimisation of oven heating in relation to mould size. Brampton Engineering of Canada says that its
single-inlet Vector air ring streamlines flow and reduces pressure losses and temperature rises – re- sulting in more efficient use of chilled air, to achive higher output on a blown film line.

Rather than split the flow of air from the chiller using a manifold to distribute it around the entry, Vector has a composite volute that is precisely contoured to achieve uniform airflow velocity around the film bubble – without excess energy, pressure losses, or an untidy mess of hoses. Infrared imaging proves that the film cools as fast – and with better uniformity – at much lower blower speeds. The air ring lip needs to control how the chilled air flow affects the film bubble, to allow process technicians to secure stable ‘bubble lock’ with a wide range of films. The Vector dual lip provides automated control of lip positions without affecting flow rate, making it easier to set up and optimise, with a wider operating window, says Brampton. All operating parameters including lip positions are precisely set with Italycs or a stand-alone control
