 Double head seamless welding machine for PVC/UPVC/Plastic/Vinyl profile window door (model:WFHJ02-4500.2A)

Product Description

Machine function

1).Model WFHJ02-4500.2A Double head seamless welding machine(Seamless welding and cleaning PVC/UPVC/Plastic/Vinyl window door),it can clear welding beading at one time after finishing the welding, and can strictly control the size of welding seam; therefore, after welding of colorful section steel is finished, its surface welding creater looks perfect and top-grade, and its welding strength is higher than that of the original ones.

2).Through controlling pneumatic system, WFHJ02-4500.2A increases processing mode of strengthening the welding strength,especially software processing in melting-welding clearance and welding process,thus it can guarantee optimal welding strength in various environments; it can also conduct quantitative adjustment according to digital parameters.

3).The cutter features good exchangeable.

The cutter of the WFHJ02-4500.2A adopts special material,via special heat-treatment processing technics and finish accuracy.The cutter is standardization completely, to achieve exchangeable,without professional the cutter can change without professional.

4).Integrative window-support welding

WFHJ02-4500.2A uses eight cutting tools to weld and clear corners and seams,and it can also conduct low-seam clearing for window-support and crossed window-support; various window-support have perfect welding surface and high welding strength.

5).Design and produce all devices for window and door,Steady welding seam/Digital prevention of material loss.

6).Special designed technique and structure ensure 0.2mm and 2mm welding auto change.

7).Any angle welding from 30 to 180 is available for this model WFHJ02-4500.2A. Here if you want to make variable angle welding, here we can add to install the variable angle welding device to one head of this machine that realize variable any angle welding.

8).Kindly note:

Before you buy the machine, please make sure then tell me your local power supply,then we can make the right according to your true voltage.

And also hope you can supply us the max.profile thickness/height of your profile, and also please inform us you want only weld common white profile or weld both common white profile and color profile, after you tell us these information, we can suggest you which model is better for you, thanks very much!


9).Specially note:

The common seamless welding machine only can weld to 100mm thickness profile, if your profile thickness is higher than 100mm, we can heighten the seamless welding machine that can weld to 150mm thickness profile,but it needs you pay some extra cost if we heighten the seamless welding machine,but if your profile thickness still is more than 150mm, and you still want to use the seamless welding, then you need to consider to buy our South Korea type Seamless welding machine,the South Korea type seamless weldin machine can weld to 280mm profile thickness.



1).One-time clean-up the welding tumor completed upon completion.

2). Can control the welding gap size strictly.

3).Therefore, color window profiles of welding is completed, the surface of the weld is very beautiful, upscale, welding strength higher than the strong point of the original profile.

4).Mainly used for colorful pvc profiles.

5).Can welding various shape profiles ,like joint-mitre,cross muntin and so on.


(PS: The PVC/UPVC/Plastic/Vinyl window door welding machine is a major and essential equipment for manufacturing PVC windows and doors. The machine heat the end of cutted PVC/UPVC/Plastic/Vinyl profiles into molten state through heating plates, and then fabricate the PVC/UPVC/Plastic/Vinyl profiles into a window door frame unit or window sash unit by pressing. The movements of profile clamping, profile melting, and frame fabricating are controlled by a PLC, and all the movements are finished one by one automatically. Welding is the most important step for making PVC/UPVC/Plastic/Vinyl windows and doors, and the welding quality (such as welding strength, welding-angle accuracy, window size accuracy) will affact the finished window quality directly. Jinan Better Machinery Company guarantees the welding quality of the PVC/UPVC/Plastic/Vinyl window door machine through adopting high quality heating plates and temprature controllers and linear line guide, and other high quality machine components, and through our strick quality control system.)
