GN Thermo- forming
Equipment has entered the
form/cut/stack market with its new GN800 model
the near future, for PS and PP sheet. The roll stack incorporates a large number of
roll gaps, to ensure reliable cooling and calibration of the upper and lower sides of the sheet, says Battenfeld-Cincinnati. This ensures a thickness profile with a variation of just 1%. Multi-Touch roll stacks work
with a combination of a roll stack with two rolls for pre-calibra- tion and three, five or seven rolls in post-calibration. This helps them to produce stress-free sheet with thickness tolerances of less than 1% at high speeds. Outputs of more than 3 tonnes/hour can be realised, depending on the width and thickness of the sheet. “We have proven that we are prepared for the growth
market packaging sheet with our high-speed extruders and the Multi-Touch roll stack – which is unique in the industry,” said Henning Stieglitz, chief technology officer at Battenfeld-Cincinnati.
High speed At K2016, GN Thermoforming Equipment of Canada is to exhibit its GN800, a high-speed form/cut/stack thermoformer. GN has already sold two units to customers in Europe. The launch marks GN’s entrance into the form/cut/
Battenfeld- Cincinnati’s Multi-Touch roll stack technology is being used by South Korean packaging producer Dongjin
stack market and expands its plug-assist machine offering. The GN800 was developed in partnership with Agripak of Italy, which manufactured and sold form/cut/ stack thermoforming machines until 2003. Based on a market analysis, GN confirmed the
growing use of form/cut/stack technology by packaging manufacturers and concluded that a partnership offered the fastest entrance into the market. “We saw the changes in the marketplace so wanted
to move swiftly to counter the competition,” said Jerome Romkey, business development manager at
GN. “We used Agripak’s proven design, and combined it with GN’s own proven technologies.” The GN800 has a forming area of 800 x 570 mm (31.5 x 22.4in) and is capable of forming 150mm above and below the sheet line. The cutting force of the forming and cutting stations is 75 tonnes. The GN800 also has additional space between the forming and cutting stations, providing extra cooling time when running heavier gauge materials or PP. It has a standard oven that is four times the index
length of the forming area. The machine incorporates high-efficiency solar heaters and is equipped with cut-in-place capabilities as a standard feature. The unit also features independent top and bottom servo-plug drives for better material distribution. The machine handles sheet widths up to 880mm (34.6in). The machine can run sheet thicknesses ranging from 0.25 to 1.5mm (0.010 to 0.060in). The unit comes fully equipped and handles all thermoformable grades of PET, OPS, HIPS, PLA, PP, and PVC. The company is currently targeting food, medical, and industrial packaging.
Cups and lids Kiefel will showcase its latest pressure forming machine – the Speedformer KMD 78 Power – at K2016, making high-quality domed lids with a precisely positioned hole for insertion of a drinking straw. The machine produces ready-bagged lids straight
from the roll of film material, with a complete configu- ration that includes printing, heating, forming/cutting, stacking and packing. The machine line will be exhibited alongside a Hapa
printing station and a bag-packer device. Two-colour digital printing with a resolution of 360 dpi allows customised designs to be applied. Individual printed designs are therefore simple to adapt, even for short production runs. The tool technology has been developed by Bosch
Sprang, and helps to ensure proper functioning of the lid (to prevent leaks) and high quality (including the
