Engel adds LWB injection unit to elastomer machines

ERJ staff report (RD)

Schwertberg, Austria - Engel has announced that LWB Steinl's patented EF-E injection unit is “now optionally available for Engel machines for immediate delivery,” a 28 April company statement said.

According to Engel, incorporating German elastomer machine builder LWB Steinl's unit bring up to 50 percent heating time reduction and improved ergonomics due to a lower operating height.

Based on a FIFO injection system mounted horizotally and using an additional “All Out” technology piston injection unit, “the main benefit offered by this new injection unit technology is gained in the use of hot runner moulds,” Engel said.

The rapid cure element between the horizontal FIFO unit and the vertical ejection unit increases the temperature of the molten material by means of dissipation, the company said, adding that this allows for more homogeneous temperature distribution in the molten material, thus increasing the temperature in the centre of the material flow rather than just at its edges.

Using the All Out technology, all the material is ejected out of the vertical injection cylinder, Engel said, explaining that this means the molten material is injected into the mould at a higher temperature. This in turn allows for substantially reduced vulcanisation times, the statement added.
