The DQL-4518S operates similarly as the DQL-5545G above. The difference being that on this machine the boxes/product can be of random lengths. The side seal mechanism is continuous whereas the DQL-5545G has an L-sealer. This machine is ideal to pack photo frames, aluminum plates, plastic piping,corning,skirting boards, wood products etc. The ideal shrink tunnel for the DQL-4518S is the DSC4525L which uses an advanced hot air circulation system for superior shrinking results and the speed of the conveyor can be set to the appropriate speed for the line.

I.DQL4518S side sealer characteristic:
1.DQL4518S is the automatic side sealing machine which developed by ourselves, it is used to high capacity packing production line, feeding, conveying, entering bag, sealing can be finished at a time, it has high working efficiency.

2.Vertical sealing adopts high quality supporting structure and two sides linear guideway to make sealing pressure balanced, frame won't be damaged easily. The sealing knife adopts copper alloy sprayed with teflon, it won't stick film, sealing fastness, without smoke, non-pollution

3.Side sealing adopts constant temperature sealing knife, sealing part is straight and strong, there is no limited about packing object length. Film feeding belt adopts widen and thicken belt, its using life is long and easily to be replaced.

4.Machine adopt "Omrom" PLC controller,

5.it is equiped with "Panasonic" photo sensor to reach high speed and automatic working.

6."Omron" temperature controller ensure sealing temperature error and "Omron" delay control sealing time accurate

7.International advanced perforating device design ensure stable working

8."Airtach" air filter to ensure enough air source for machine

9.It equiped with touch screen is easier to change the size

10.it has protection function to avoid sealing product wrong and ensure the safety of operator

11.Nice design of the cylinder which will adjust the open distance of the two sealing bar.


II. DSC4525L shrink tunnel characteristic:
1.Solid roller rotate with conveying chain, at the same time solid roller rotate by itself, down side sealing effect of object won't affect by roller, each side sealing effect is firm.

2.It adopts high-power fan motor to ensure enough strong wind to reach perfect packing effect.

3.It adopts spiral type heating element to ensure enough heating and long life

4.Complete machine with heating resistant cover

5.Inspection window can inspect product shrink situation and adjusting easier
