Meanwhile, to cater to the growth of insert moulding, Nissei was promoting its vertical tiebarless TNX100RIII8V, which was displayed with a six-axis, multi-jointed Kawasaki robot, 3D imaging and flexible insert system, without a transfer device. Another smaller vertical machine, with a clamping force of 19 tonnes, affords space saving features.

plastics (CFRPs).
On its 100-tonne machine, JSW exhibited a newly designed blending system and screw/barrel for optimised processing of CFRP The number of visitors to IPF increased, over the 2014 show
The part was moulded on a J280ADS890HCFRTP/UD-tape injection moulding cell in a single-cavity mould with a cycle time of 48 seconds. JSW claims that the carbon fibre tape, which is added to the mould prior to moulding, can increase the rigidity of a part ten-fold. The tape, with a thickness of 0.5 mm, comprises up to 60% carbon fibre, with the remaining 40% made up of the same resin used for the part. Toray says this patented tape impregnation process, allows for a permanent bond in the part. Toray and JSW also jointly designed a new tape reel machine for unwinding the tape, which is incorporated with the manufacturing operation, but is controlled independently. Another Japanese machine maker Toyo Machinery was also demonstrating the production of a CFRP part on its latest all-electric, vertical rotary
Catering to large moulds on small machines Celebrating its 70th anniversary last year, Nissei Plastic Industrial displayed six machines. Its 220tonne NEX220IV all-electric machine, now available in the market, is a newcomer, designed to accommodate larger, more complex moulds, and a faster cycle time of 4.5 seconds. Another machine, also with the capability to accommodate larger moulds, is the prototype FNX220IV-50A, a 220-tonne hybrid machine able to cater to moulds that would normally be mounted on a 350-tonne machine. It was also displayed with the company’s N-SAPLI low pressure moulding system, which optimises the clamping force, boasting longer tool life and lower peak pressure, said Nissei. 4 JA N U A RY / F E B R U A RY 2 018
