HDHS
Automatic table for hinge holes on PVC doors
High-precision automatic drilling, immediately after welding.
Perfect if you want:
- Automate hinge drilling to reduce manual interventions.
- Eliminate positioning errors through precise references.
- Reduce the clutter downstream of the welder.
- Integrate a process that is often manual into an online system.
- Enhance the quality and consistency of the doors.
- Working with just one operator

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 bidirectional drilling head and precise pneumatic locking, the 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.
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 drills the frame, allowing a single operator to manage the entire cycle.
- 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 intuitive interface. Easy setup and management: even non-expert 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 perfect locking of the door during processing.

Optional and configurations
HDHS can be customised upon request to accommodate various levels of automation and production layouts.
Among the available options:
- Head positioning on a controlled axis: for greater flexibility and integration with CNC management software.
- Custom configurations for compact layouts or dedicated production flows
Thanks to its modularity, HDHS is suitable for both small semi-automatic lines and fully automated systems.
Technology and automation at the service of precision
The machine is operated by a highly reliable pneumatic logic system, integrated with an automatic depth regulator that ensures consistency in every operation.
Available in a version that can be integrated into digital systems, HDHS can be set up for Industry 4.0 and connected via application tags for remote control, backup, and predictive assistance.
GRAF Synergy provides comprehensive technical support, from installation and operational training to advanced cloud maintenance.
