SJ-25 MARK LINE EXTRUDER | MINI LAB EXTRUDER
SJ-25 MARK LINE EXTRUDER is best choice for co-extrusion products, and products with mark
This type of marking line extruder is not usually used alone, especially widely used on pipe production line to co-extrude pipe
This extruder is specially designed with lower power consumption
and takes smaller space.
The Barrel and Screw unit adopts optimized structure, which is easy to meet regular Material Test Requirements.
- 8 Directions Adjustment is very convenient for testing operation from different angle.
- Screw and barrel in high-grade nitride steel, screw diameter 25mm, L/D 25:1, 28:1, 30:1 available based on different material.
- Stainless Steel Protection Cover designed over the extruder barrel will fully protect humans from
hot heating band.
- Specially Designed Screw ensures very good feeding properties without material bleeding out
of the vent.
- Screw speed infinite variable from 0 to 100 rpm, which could meet
regular extrusion requirements.
- Digital Display for heating temperature, current, which will be convenient to make
- Convenient control panel mounted over extruder barrel in an
upstraight angle for easy viewing.
- This single screw extruder can be designed with PLC Control System, which will realize full automatic adjustment of the following
downstream equipment of the extruder production line.
New high performance alloy steel is used in screw and barrel, which
has the advantages of corrosion resistance, wear resistance, high
strength and so on.
There are two kinds of structures in the heating section of barrel,
groove and smooth section, which can meet the demand of different
The screw geometric parameters can be customized according to the
customer ' s requirements , different raw materials can be used for
different products , and the screw adopts different L/D and
structure to meet the needs of different customers.
