Analysis of the application of cutting steel door and window profiles

The plastic steel profile is made of polychlorohexene resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and extruded. When cutting the steel profile, ensure proper feed speed; blunt serration or too fast feed rate will cause the incision defect; precisely adjust the blade angle to 45 degrees, the maximum angle error is 0.5 degree; strictly follow the given length limit The length error shall not exceed 0.5mm; the cut profile shall be placed with the incision facing down and the welding shall be completed within 48 hours to avoid excessive storage leading to contamination of the surface of the incision and affecting the quality of the welding. The feed rate and cutting speed of the drilling hole decrease with the increase of the drilling depth; the double-groove drill bit should be used for the hole diameter larger than 20mm, and the progressive lightening drill bit should be used for the hole with the diameter larger than 40mm.

Do not stretch excessively to insert any strip, and ensure that the length of the glue is about 2% longer than the length of the insert groove. The seal between the fan of the casement window is a length of glue around the circumference, and the joint should be on the upper side. Do not dock at the corner, let alone cut into several segments. The strip should be flat at the corner. The sealing strip of the press-fit glass should be cut and butted at a 45 degree angle to ensure that the length of the strip and the cutting angle are tightly joined. Color bonding at the strip interface for better sealing. Select the appropriate type of seal according to the thickness of the glass. The sealing strip must be completely grooved to ensure the sealing effect and the normal installation of the glass. Many connections are not allowed in the same tank.

The grade of the window not only includes a good looking appearance, but also a superior performance. Therefore, the plastic steel window can also take into consideration the beauty and high performance. Of course, the production technology of plastic steel window should be an organic collection of various technologies such as material selection, design, processing, human function, and aesthetics.
