OEM CNC Factory Precision Machining Extrusion Screw and Barrel
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,
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.
Main parameters of screw and barrel:
|Material||38 CrMoAlA(JIS SACM645); 42CrMo(JIS SCM440)|
|Hardness of nitrogen treatment||HV900°~1100°|
|Tempering hardeness||HV240 ° ~280°|
|Depth of nitrogen layer:||0.6~0.8mm|
|Nitrided Brittleness||above 1 stage|
|Surface Roughness||Ra0.4 um|
|Hardess of surface chromium-plating after Nitriding||HV≥950HV|
|Chromium plating Depth||0.025-0.085mm|
|Heating-treatment||nitrogen ,electroplated hard -chrome finish,high frequency
Remarks :We can design and manufacture various kinds of screw
barrel according to the customers requirement.
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
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.
