High efficiency and low consumption! Injection moulding corner code becomes a new choice for door and window building materials

Recently, injection moulding corner code has received wide attention in the field of door and window building materials by virtue of its stable performance and cost advantages.

Its production focuses on precision: raw materials are dried and processed, then melted at high temperatures by a screw injection machine and injected precisely into the customised mould cavities. The mould is made of 38CrMoAl alloy to ensure that the 90° right-angle error of the corner code is ≤0.1mm, and after cooling and shaping, the whole process takes only 45 seconds/piece through automatic trimming and quality inspection and sorting, which is 3 times more efficient than the traditional stamping process.

It has diversified application scenarios: in aluminium alloy doors and windows, it achieves seamless splicing of frames and sashes through snap-in installation, which improves wind-pressure resistance by 20%; for curtain wall decoration, it can be adapted to profiles with different thicknesses of 3-12mm, which shortens the installation time by 40%. A building materials company's test shows that after adopting this corner code, the rework rate of door and window assembly is reduced from 8% to 1.2%. At present, this corner code has passed ISO9001 certification, suitable for mainstream door and window profile specifications, is becoming a preferred accessory for small and medium-sized building materials manufacturers to reduce costs and increase efficiency.

At present, the injection moulded corner code has formed a series of products for residential, commercial and special environments, and is suitable for more than 20 mainstream profiles.

Industry insiders believe that the expansion of its scenario-based application is promoting the upgrade of door and window connecting accessories from "general-purpose" to "customised adaptive".
