   Product details

Brief Introduction of CNC Four Head Corner Crimping Machine
The CNC four-head aluminum corner crimping machine is used for 90 degree corner joining of aluminum profiles. Place a corner connector into the cavity of the two profiles before corner crimping, and the hydraulic-driven crimping knives make permanently cold deformation on aluminum profile outer layers. Using CNC control system, finishing four corner joining for a window frame or sash in one operation, the corner crimping machine is ideal equipment for mass production of aluminum doors and windows.

Features of CNC Four Head Corner Crimping Machine
● Adjusting the size of aluminum doors and windows automatically, finishing the connection of four corners of a window frame or sash in one operation, high efficiency
● Servo motors and precision ball screws control the movement of four crimping units, which guarantees the repeatability positioning precision
● CNC control system and human-machine interface touch screen, easy to operate
● Powerful hydraulic system provides strong and stable pressing force for crimping knives, ensuring big punching and riveting force and high strength of corner connection
● Reinforced clamping guide rod can prevent malposition of aluminum profiles
● Clamping device can move forward and backward automatically, easy to load and unload window frames
● Height of crimping knives and depth of crimping can be adjusted to meet requirement of different aluminum profile types
● Profile clamping is pneumatic, and the feeding movement of crimping knives is hydraulic
● Achieve centering of profile corner automatically with hydraulic profile centering devices

Aluminum window corner crimping machinery is major and essential equipment for manufacturing aluminum windows and doors. This kind of machines make permanently cold deformation on aluminum profile outer layers by pressing aluminum profiles with corner inside, making the corner connectors and aluminum profiles connected titghty to finish corner crimping. Corner crimping is the most important step for making aluminum windows and doors, and the quality of corner crimping (such as crimping strength, crimping accuracy) will affect the finished window quality directly. Stone Window Machine Company can provide CNC four-head aluminum corner crimping machine, double-head aluminum croner crimping machine, single-head corner crimping machine, and multi-bytes corner crimping machine.
