Engel's injection moulder is largest by
volume
Engel in Austria has claimed to have built the world's largest plastics injection moulding machine, which has shot weights up to 140kg and a platen locking force of 55MN.
A plastics moulding company, Graf Teningen,Gemany, has commissioned Engel of Austria to build a two platen plastics injection moulding machine with a clamping force of 55MN The machine has three injection units to produce underground tanks and logistics containers

Automating pulley moulding
An Engel unmanned injection moulding line, conceived with rapid mould change-ocver, is producing a wide variety of automotive drive belt pulleys for the Dutch enterprise Axxicon.
Automation boosts injection moulding quality
The prime aim of the automation of injection moulding systems is not to save high labour costs but to ensure high process and product quality, says Engel.
Engel said it has broken all previous records with this development.
The duo 5500 not only supports shot weights of up to 140kg with its three injection units, but is also very economical with its extremely low energy consumption.
About three years ago, Engel was asked to develop an injection moulding machine for shot weights of up to 150kg.
The resulting machine is the Engel duo 5500 with a clamping force of 55MN (5,500tonf) combined with three parallel action injection units.
Each injection unit has a screw diameter of 260mm each to produce a Graf 6,500 litre Carat underground tank.
The 25m injection moulding machine has a total weight of 585 tonnes.
Add to this the mould weight of up to 160 tonnes.
Due to its size, the machine had to be installed 2m below ground level.
These parameters, said Engel to manufacturingtalk, make the machine the world's biggest injection moulding machine of its kind.
Its specific energy consumption is only 0.34kWh/kg under production conditions, with which, said Engel, the machine achieves record breaking savings.
* Editorial comment on large injection moulding machines - in terms of shot weight and volume, Engel's machine is the largest built so far.
A US company built an 80MN (8,000 tonf) locking force machine some six years ago.
Though a very large machine, its shot weight was 50kg.
The machine was leased to the then Chrysler Corporation and involved in a plastics bodied car project, then later sold by the machine builder to a plastics container manufacturer.
The plastics industry has apparently built large machines in the past - up to 10,000/11,000 tonf (100-110MN) clamping force, but maybe not to such a large shot weight and volume capacity as the Engel machine - Ed.
