Corrugated Rollers Advantange:
1. The coating is firmly combined with the substrate to ensure long-term use of the coating without falling off;
2, the coating hardness is high, wear resistance increases exponentially, life is linear extension;
3. The coating thickness is uniform and controllable, that is, the precision of the corrugated wheel can be guaranteed;
4. The surface roughness before coating treatment can reach ra0.3-0.5um. After grinding with special diamond grinding wheel cutter, the surface roughness reaches and is higher than the surface roughness of electroplated hard chromium roller.
5. Cooperate with UV type and UVV type corrugated design, can effectively improve the hardness of cardboard, reduce the amount of paste and waste of core paper;
6, in the use of the corrugated type, the theory of wear and tear, long-term guarantee the paper rate unchanged;
7, corrugated roller since the use of the machine, the production of cardboard maintained in the thickness, printing always flat, stable control of cardboard and carton quality;
8. The coating is removed by special method, and the wheel blank can be reused;
9. The improvement of service life reduces the frequency of change, which also saves labor and material costs;
Packaging & Shipping
1.Packing : Use non-fumigation wooden box, it's convenient to customs clearance.Could save customers more time.
2.Delivery Time:Shipped in 60days after payment
Inspection of corrugated roller before installation
(1) clean and check the corrugated surface appearance of corrugated roller (including the quality of surface plating).
(2) clean and check all fastening parts of connection (including internal and external threads).
(3) check the outer diameter and middle height of corrugated roll (the whole roll surface is divided into more than five measuring points from both ends to the middle).The middle and high detection points are odd, and the middle and high data should be symmetrical on both sides.Measure with the outside diameter micrometer of corresponding specification (outside diameter micrometer can be bought commonly by electromechanical company).
(4) check the corrugated roll height.Needle type depth dial meter measurement (needle type depth dial meter is not currently bought in China, must be imported.Or may use the ordinary depth dial gauge to change the system).
(5) clean and check the outer diameter and appearance of each shaft gear of corrugated roller, and measure the outer diameter with the micrometer of corresponding specifications.
