What problems do you often encounter when assembling Window and Door Profile? Plastic steel profile wholesale analysis for you:
1. The profile is bent and deformed before cutting
The bending deformation of the profile before cutting mainly occurs in two forms:
1. Bending deformation during production
2. Bending deformation of the profile due to improper storage or transportation
2. Discoloration of the profile
The discoloration of the profile is mainly due to improper process control and unreasonable adjustment of the formula system during the production process. Secondly, it is caused by lead sulfide corrosion in the air.
Three, profile cracking
The profile cracks directly along the weld or gradually extends to the section after cracking along the weld, mainly due to poor welding technology, inaccurate cutting size or improper construction. The welding process mainly refers to the process temperature, blanking size, and welding technique.
Fourth, the gap between the mating point of the bead and the fan is too large
The excessive gap between the mating point of the bead and the fan is mainly caused by the improper production operation of the profile production line. In this case, the customer should be replaced in time.
Five, there is a clear yellow line at the contact between the profile and the rubber strip
The obvious yellow line at the contact between the profile and the rubber strip is mainly caused by the lead sulfide produced by the reaction of sulfur and lead in the inferior rubber strip. In this case, the assembly factory should be advised to replace the high-quality rubber strip in time.
