SJ25-25 co extrusion single screw extruder

SJ25-25 co extrusion single screw extruder structure:It is an important component of co extrusion technology, specially developed to adapt to small co extrusion flow and be able to interface with different forms of hosts. In co extrusion molding of profiles, the extruder that extrudes "small materials" is generally referred to as SJ25-25 co extrusion single screw extruder, and the extruder that extrudes the main profile is referred to as the main extruder. For co extrusion of hard PVC profiles, twin-screw extruders are commonly used as the main extruder, single screw extruders are commonly used, and small machine series such as 25 and 30 are mostly used. The main purpose of the extruder is to be used in conjunction with various main extruders, and it can also be used independently with appropriate heads to produce various products.

　　The main difference in structure compared to ordinary extruders lies in the design of the frame. According to the different racks, they can be divided into two types: external and online. External installation can be divided into three types based on the installation position: vertical, horizontal, and angular; The online type can be placed on the main extruder or on the shaping table.

Has the following characteristics:

① Compact structure and small footprint;

② Small control system, easy to operate;

③ Mobile rack, easy to disassemble and repair;

④ Convenient channel interface with strong versatility.

In co extrusion technology, the layout of the extruder is also important. For newly built extrusion systems, if space permits, extruders can be arranged side by side or in a star shape, and can be designed in a compact and easy to operate and maintain form; For the existing extrusion system, the above layout can be used, or it can be installed shoulder mounted on the main extruder.
