摘要:
An apparatus for controlling temperature of materials in a flowable state as they flow through a barrel. The apparatus includes a band surrounding the barrel having a plurality of connected blocks, each block having an inner surface in communication with the barrel. One or more of the connected blocks has a slot therein and has a removable, temperature controlling mechanism slidably received in the slot. A flexible cover surrounds an outer surface of the band with the flexible cover having a pouch for receiving a temperature sensing element.
摘要:
The invention relates to an overturning device (10) for overturning molten material (200) in a melt channel (110), comprising a melt inlet (20) and a melt outlet (30), at least one melt guiding means (40) being arranged between the melt inlet (20) and the melt outlet (30) for moving molten material (200) from the center (22) of the melt inlet (20) to the edge (34) of the melt outlet (30) and for moving molten material (200) from the edge (24) of the melt inlet (20) to the center (32) of the melt outlet (30).
