Extruder screw and barrel are widely used in the plastic processing industry; they can used in the thermo-plasticit , thermo-set plastic , rubber, elastomer- plastic. We can design targeted screw and barrel according to the different resin grades and formula feature to meet the production and quality demand. They are applied in the plastic extrusion equipments as profile, tube, profile bar, rubber tire, conveyor belt, thin film, sheet, board, wire rod, granulation.

We can make the drawing according to your requirements,like the material, the machine, and the output,etc. And also we can do by your own drawings with our suggestions.

Dia of the meltblown machne screws will be 60 / 65 /90mm and so on.

1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.
4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.


1. Be brushed anti-corrosive oil on screw barrel.
2. Packed with film.
3. Packed in the wooden carton.
