1. The influence of aluminum raw materials on the angle of door window assembly system window profiles

The raw materials for aluminum profiles are very important. If the raw materials are good, the angle strength of the window cannot be achieved. If the impurities in the raw material are high, sparks will be generated during cutting, the noise is relatively high. The angles cannot be strictly matched.

2. The determination of aluminum aging aluminum strength

6063 (brand) is generally used for aluminum profiles, the processing status is divided into T5 T6 (air cooled water cooled). The strength hardness of water-cooled T6 will be higher. The Vickers hardness of aluminum is 8 °, T6 cannot be used for all profiles of a window. If the profile exceeds 14 °, during the factory processing, the insulation strip explodes through the strip, forming a curved window. The difficulty of pulling bending irregular window profiles is high, the plasticity is low;

3. The impact of extrusion mold accuracy on the accuracy of door window angles.

If the accuracy of the mold is enough, it cannot achieve the accuracy of the aluminum profile extrusion mold. Accumulation of wear spray accuracy deviations leads to overall accuracy deviations;

4. The influence of mechanical performance design on strength

Firstly, what we want to say is that the thicker the contour, the better. When designing contours, we should design a mechanical perspective. If we find the place the stress point should be thick, the place it should be thin should be thin, which only ensures the strength of the door window contour, but also reduces the pressure on the door window hardware;

5. The relationship between insulation strip material aluminum material.

The insulation strip material is generally made of polyvinyl chloride for doors windows. The insulation strip looks thicker, some homeowners feel that purchasing it is more valuable; High end doors windows will choose PA66GF25 insulation strips. GF25 is the content value of glass fiber, PA66GF25 insulation strips have the same coefficient of expansion as aluminum, with good stability;

Before the heat insulation strip aluminum material are pressed together, a process is required: tooth opening. If there is no such process, the contact surface between the heat insulation strip aluminum material is flat without resistance Bite force quotient, which affects the overall strength of doors windows. In order to save costs, some manufacturers have saved this process by only decorating teeth on the surface, which looks like teeth;

6. Surface treatment of profiles

Surface treatment is generally divided into two types: vertical spraying horizontal spraying. Vertical spraying refers to the vertical spraying of door window profiles, so the spraying effect is good. The corners of the high profile are smooth arc free, the gap between the profile the contact surface is small. Horizontal spraying is the opposite. The original factory color in general is vertical spraying, the later color selection subsequent spraying are horizontal spraying;
