Maximum efficiency in the post-welding phase
HDHS is the automatic machine designed by GRAF Synergy to optimise the drilling phase of hinges on PVC doors.
Thanks to its bi-directional drilling head and precise pneumatic locking, HDHS ensures fast, repeatable results that are perfectly aligned, starting from the most reliable geometric reference: the outer edge of the frame.
Designed to be installed immediately after the welder, the HDHS not only automates a critical phase of the process but can also completely replace the traditional cooling table, reducing space and labour requirements.
A perfect ally for window and door manufacturers looking to boost productivity, eliminate manual errors, and seamlessly integrate hinge processing into a compact line.
5 Reasons to Choose HDHS
- Automatic and precise drilling. Thanks to the mechanical positioning of the head and the reference on the outer edge of the door, each hole is perfectly aligned.
- Fewer operators, fewer errors. The machine autonomously moves and removes the frame, allowing a single operator to manage the entire process.
- Smart Integration. It can replace the cooling table: same footprint, one extra function, no wasted time.
- Consistent quality in every cycle. The drilling depth is managed by an automatic regulator: each panel is ready for assembly, without any touch-ups.
- Simple and straightforward interface. Intuitive setup and management: even inexperienced staff can operate confidently.
Product Details
HDHS is specifically designed for drilling hinge holes on PVC doors. Its compact and functional structure houses a bidirectional drilling head with mechanical positioning, along with a set of pneumatic clamps (2 horizontal + 2 vertical) that ensure the door is securely held in place during processing.
