PVC imitation marble profile production line needs a hot-stamping unit additionally.
PVC edge banding production line needs a winding machine instead of cutting machine and stacker.
1.DTC type screw loader
Our screw loader was set with limited switch, which can guarantee feeding enough but not feeding over.
We have DTC300, DTC500 and DTC1000 models for you to choose from according to capacity requirements.
2.SJZ series Conical double screw extruder
a. Extruder is driven by SIEMENS motor and its speed is adjusted by ABB inverter.
Screw & barrel adopt nitriding process whose hardness could be 800-900HV. Its material is 38CrMoAlA, normally bi-metallic. And if too much Ca2Co3 is added in your formulation, you can choose SKD material.
b. It is equipped with parallel twin screw feeder, which feeds equally and continuously.
c. Vertical type gearbox could be chosen, which makes the machine look more beautiful and save space.
d. When the material is not dry enough, vacuum pump can be used to dry it enough by pulling out the air changed from melting water.
e. According to different products and capacity requirement, we have
SJZ45, SJZ51, SJZ55, SJZ65, SJZ80 & SJZ92 models for you to choose from.
3.vacuum calibration table
This part machine is used to support dies, supply water and vacuum.
a. Aluminum guider is used to set cooling & forming dies.
b. Water pump + stainless steel water tank + water tie-in ensures enough cooling water to cool the products and sizing processing.
c. Vacuum pump + tie-in is used to make vacuum space of the forming die which is needed to shape PVC profiles.
d. Profiles with different widths need different model vacuum calibration table as well as haul-off & cutter.
For example, for 150mm & 200mm wide window profile, we should choose YF240 model while for 600m & 800mm door panel, we should choose YF800 model.
4.haul-off & cutting unit
Rubber type haul-off unit is used to support enough hauling force to guarantee a continuous production process.
a. It is driven by SIEMENS motor and its speed adjusting by ABB inverter.
b. It is equipped with Autonics encoder, counting & supporting cutting signal to cutter.
When cutter gets the cutting signal, motors start working and cutting the profile. After cutting, the profile length is the same as client’s requirement (length can be set, in the driven SIEMENS PLC of cutter)
It is used to store finished profile and waiting package.

1.Other Auxiliary Machines, such as crusher, mixer, will be provided according to client’s requirements
2.PVC imitation marble profile production line needs hot stamping before hauling off additionally.
PVC profile extrusion line: PVC powder + various additives for different profiles
WPC profile extrusion line:
PE/PP WPC Profile Production Line: PE/PP pallets + wood powder + other additives (used to produce exterior decorative building materials)
PVC WPC profile production line: PVC powder + wood powder+ other additives (used to produce interior decorative building materials)
