Possible issues in assembling UPVC doorways and windows

What issues do you regularly come upon when assembling UPVC Profile doorways and windows? LUMEI Profile analyzes for you:



1. Bending deformation of UPVC Profile earlier than cutting

The bending deformation of UPVC Profile earlier than blanking on the whole happens in two forms:

1. Bending deformation all through production

2. Bending deformation of the profile due to incorrect storage or transportation

2. Discoloration of UPVC Profile

The discoloration of UPVC Profile is in general due to mistaken procedure manipulate and unreasonable adjustment of the system device at some point of the manufacturing process. Secondly, it is triggered by using lead sulfide corrosion in the air.



3. Cracking of UPVC Profile

UPVC Profile cracks immediately alongside the weld or progressively extends to the part after cracking alongside the weld, by and large due to negative welding technology, inaccurate reducing dimension or mistaken construction. The welding manner more often than not refers to the manner temperature, clean size, and welding technique.


4. the hole between the mating factor of the bead and the fan is too large

The immoderate clearance between the bead and the fan is on the whole due to the flawed manufacturing operation of the UPVC Profile manufacturing line. In this case, the patron have to be changed in time.



5. There is a clear yellow line at the contact between UPVC Profile and the rubber strip

The apparent yellow line in the contact between UPVC Profile and the rubber strip is broadly speaking induced with the aid of lead sulfide produced by means of the response of sulfur and lead in the inferior rubber strip. In this case, the meeting manufacturing unit ought to be suggested to substitute the incredible rubber strip in time.
