Qingdao Tongsan Plastic Machinery co.,td have been develop the PP hollow corrugated sheet making machine since 2015,now we have the machines for the PP hollow grid plate width from 1220mm to 2450mm and thickness from 1.5mm to 12mm.
We have different model production line,such as the 1400 type PP hollow sheet extruder machine,1860 type PP corrugated sheet production line,2300 type PP hollow corrugated board making machine,2600type plastic hollow grid panel making machine,and for each model,we have the co-extrusion type for customer choose.The co-extruder type can use 20%-60% fillermatch for reduce the cost,so our customer can product the cost competitiveness sheet with good quality.Our machine have the advantage of high output,easy operation,high precision,good products with smooth surface straight rib.
Qingdao Tongsan hollow corrugated sheet making machine can produce the sheet with the width of 1220-2450mm and thickness of 1.5mm-12mm

The production line adopting the co-extrusion mode,so the recycled material (80 %-90 %) can be used in the middle, and new material can be used for the surface. The product has smooth surface which no visible difference to the naked eye, so it can reduce a lot of costs.
The mold adopt special steel which made with Italian formula technology ,it has the characteristics of memory rebound.The mold is more wear-resistant and the service life is several times longer than ordinary mold.
One set mold can produce different thickness range ,such as 2mm-5mm,5mm-8mm,8mm-12mm,just by change the center of the mold.
The screen changer adopt silk screen circulation, altogether 4 pcs silk screen, 3 normal use, 1 standby . It does not need to stop when changing the silk screen .
There are 6 rollers on the front haul off machine and 3 rollers on the second haul off machine ,so the production line is more stable.
The haul off machine adopt helical gear
The haul off machine and the calibrating platform are on the same guide rail for convenient synchronous alignment adjustment.
We adopt fan cooling style, the cooling speed can be fast.So it won’t shrink after cutting, it can effectively reduce the error.And the speed of production can be more fast.
The oven’s material is 201# stain steel,there are total 4 meters with two 2 meter oven.The customer can choose to use one or two according the product need.
