1. The weighted design effectively ensures the accuracy of the equipment and its long-term accuracy.

2. The angle assembly space and propulsion force of the angle assembly mechanism are increased, up to 7 tons, suitable for large-size door and window profiles.

3. The lifting positioning mechanism makes it more convenient to put and take materials.

4. The angle assembly height is 150mm, and the working efficiency is high.

5. The angle assembly force is strong, the angle assembly is flat, and there is no dislocation.
