Window Die For Aluminum Frame Slot Punching And Corner Notching

Product Details:
Fabricating aluminum window frames often involves separate steps for drainage slots and assembly notches. Our window die combines these: one press cycle punches the slot for a lock and notches the corner for a tight fit. This halves the handling time and improves consistency between profiles, leading to better frame squareness.

The die has interchangeable punch inserts for different slot lengths and shapes. Guides are machined to match the exact profile cross-section, preventing any rotation during the punch. A manual or pneumatic clamp holds the profile securely during operation, keeping hands safely away from the working area.
It fits onto a small hydraulic press or a dedicated pneumatic punching unit. Adjustable depth stops control slot location precisely. For profile sizes up to 90mm, the die provides plenty of clearance. It is a cost-effective way for window manufacturers to bring slotting and notching in-house, reducing expensive outsourced work.
