鋁門窗單頭組角機主要用于角碼結構的平開門窗 45 °接縫的擠壓聯結。
組角前，在兩個被聯結的型材腔內放一公用角碼，定位夾緊后，兩個液壓驅動的沖頭強力沖向角碼的凹槽處，使型材外壁產生永久性的冷變形。將兩型材接縫擠壓，使聯結具有螺釘或其它聯接方法所不具有的高強度、高效率、高精度。
The machine is mainly used for extrusion and connection of 45 ° seam casement window with angle joint structure.
Before operating, place a corner-brace in cavities of two profiles to be connected. After locating and clamping,the two hydraulic driven punching blocks punch towards the flute of corner-brace, making the outer wall of the profile permanently cold-deformed. Extrude the seam of two profiles and make strength, efficiency and precision of the connection higher than using any other means for connection.
