4,Turnkey Service Provider
Let customer experience a sense of entitle,respond within 24 hours,solve problem within 48 hours.We will work 24hours*7days for the after-sell service.
5,Pursuit of Excellence
Devoting to the research,development and production of various plastic extrusion machines.It is always making innovations and keeping up with the times.
Our hollow corrugated sheet making machine can produce the sheet with the width of 1220-2450mm and thickness of 1.5mm-12mm.
The specially designed screw and the advanced controlling system ensure excellent plasticization,high output and stable extruding.We have the co-extrusion type to use the recycled plastic to reduce the cost with high quality products.
Mould adopts high-quality alloy steel and throttling device to ensure even pressure of feed influent at the mould lips,and also differential action of up-down piece guarantee even thickness of the plate.
Vacuum system composes two independent subsystems and each is equipped with several fixed circulating vacuum lines of three-point type.Meanwhile,each line carries vacuum regulating system and vacuum display system that realize even and stable vacuum degree of plate surface.
There are two tractor.The first one is high power,high reduction ratio,multi-roller type,well low-speed operation,high traction and is able to draw the plate up from the calibrating table evenly and synchronal.The second one is designed to remove stress,and in addition it is equipped with edge-cutting device to ensure the valid width and smooth cut of the edges.
The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.
