EVA TPE TPU TPR thermoplastic plastic pellet extruder with
underwater cutting system
Plastic Compound Underwater cutting system Working Principle:
The working principle of the traditional extrusion pelletizing is
to melt and filter the plastic adopting the single extrusion or
twin screw extrusion the strand or hot face cutting system to
produce the granules,finally cooling or solidified to
cut.However,the under water plastic pelletizing machine is a new
machine which is in the moment of mel pump extrusion to touch with
the cold water,then cut directly.Melting pelletizing has some
obvious advantages compared with solidifying pelletizing.
Plastic Compound Underwater cutting system Advantages:
1. For plastic being cut off in melting status,then solidification
through circulation water.So different viscosity high polymers all
can adopt this cutting type.There is no any dust,shape
structured,easy package and transport in melting to cut plastic
2. It can change the size and shape as per the extrusion rate and
cutting speed to adopting different die heads.It also can use
different Qty of knife to change the size and shape of plastic
3. The cutting plastic granules and cooling system are in one
combined which saves the 4~6mm water tank,reduces the area of floor
4. This technology realizes automatic production,easy to
operate,low noise,good granules quality.
5.Bigger capacity than water strand,lower power.
Plastic Compound Underwater cutting system
1. Hot melt adhesive pelletizing line:
These water ring pelletizing/ water-spray pelletizing/ under water
pelletizing line can handle more than 5000PCS hot glue without any molten cooler. Some low stickiness hot glue
only need to add a molten cooler.
Like: a) EVA series. b)Nylon series. c)polyester fiber series. d) various
2. Common elastomer:
Styrene Thermoplastic elastomer(TPS): SBS,SIS, SEBS, SEPS and so on.
Polyolefin Thermoplastic Elastomer(TPO,TPE-O, or TEO):
separate mixed infiltration S-TPO
Dynamic vulcanizing TPV(PP/EPDM),TPE,TPA
