Update 1
Published 1yPublished almost 2 years ago
We've been progressively upgrading our hand-cranked Zephyr Bros. Benchtop Extruder to accept a detachable motor for new + existing customers. A key concern was providing operators a way to monitor for full moulds or blockages in order to safely produce parts with their machine.
The solution: To install a melt pressure sensor/transducer, however we needed to make changes to our existing nozzle. Since the nozzles needed to fit machines with differing internal thread starting points (machines of new and existing clients), we designed them with 2 mounting positions. This ensures the pressure sensor can always be installed correctly, regardless of thread location.
The success of this pressure monitoring system on the Benchtop Extruder has led us to develop a similar solution for larger Precious Plastic extruders. Facing the same challenge of diverse thread starting points, we're creating a slightly larger nozzle, maintaining the same versatile mounting style as the Benchtop version.
