Extrudates, as we usually see them, can be either continuous (in theory, the material produced is of any length) or semi-continuous

(producing a lot of debris). It can be hot or cold, in the process of extruding the material. PFA management belongs to the former.

The PFA extruder extrudes the raw materials through the cavity and die, through heating, using the shear of the screw and the

friction force of the raw materials themselves to make various specifications.

Because the PFA mold has no way to support the central barrier, cavities in the internal extrusion material cannot be produced using

a simple flat extrusion mold. In contrast, in the mold, the shape and depth of the piece are assumed first, and the shape outline

supporting the central part is used first. The mold shape then changes along the inner length to the final shape, supported by a

suspended center from the back of the tube core. Therefore, PFA extrusion is usually used with a multi-strand split, usually three or

four strands.

Shenzhen Dankai Technology Co., Ltd. can produce more pressure-resistant, explosion-proof and better PFA tubes by improving the

ratio of screw, cavity and mold, as well as proper deployment of temperature and mold core, which is also common among our

customers of PFA tube extruder.

ShenZhen DanKai Technology Co.,ltd. is an intelligent manufacturing enterprise specializing in the R & D, production, sales and

service of FEP, PFA, PTFE,PVDF and other fluoroplastic tube, bar, sheet and film products as well as other insulating materials.

The company has a senior research and development team of international standards and imported fluorine plastic products

production line, some fluorine plastic products passed ISO9001, SGS, FDA certification.

The main products are: ① pipe: PTFE polytetrafluoroethylene pipe, FEP pipe, PFA pipe, PVDF pipe; ② Heat-shrinkable tubes: PTFE

heat-shrinkable tubes, FEP heat-shrinkable tubes, PFA heat-shrinkable tubes, PVDF heat-shrinkable tubes; ③ Plate and rod films:

PTFE plate and rod film, FEP plate and rod film, PFA plate and rod film, PVDF plate and rod film; ④ Insulating materials: silica gel, PE,

PVC, UPE, etc.; ⑤ Special class: PFA inlet joint, spiral pipe, spring pipe, rotary cut pipe, welding rod, tee, straight, gasket, joint, taper

rod, flaring pipe, sealing pipe, braided pipe, corrugated pipe, etc. At the same time can be customized processing production of

various specifications of fluorine plastic products.
