Why Hongrun
The groove decides the box.
A rigid box is only as square as its grooves. Too shallow and the corner cracks; too deep and it tears. Drag the sliders to see how angle and board thickness shape the cut our knives make.
Illustrative section with 0.2 mm skin left under the groove. Held to ±0.10 mm at maximum precision.
- 01
One-way deviation correction
Our original single-side wheel system squares every blank against the guide before it meets a knife. Boards that arrive a few degrees off still leave with grooves parallel to the edge.
- 02
Four-corner waste cleaning
Corner cut-outs are separated at the knife and carried away on a side-discharge belt — or to a single point on the HR-900P. Nobody reaches into a running line to clear trim.
- 03
V, U and L profiles on one frame
V and U grooves for crust paperboard, L-grooves for trimming density-board edges. Knife rows swap in minutes, so one machine covers your whole box catalogue.
- 04
Built under ISO 9001
Every machine is assembled and run-tested in our Rui’an plant under an ISO 9001 quality system with TS 16949 management practice, and protected by our own utility and design patents.

The factory · 宏润机械
Designed, machined and run-tested in Rui’an.
Wenzhou Hongrun Machinery Manufacturing Co., Ltd. researches, builds, sells and services equipment for the fine gift-box industry from our own plant in the Dongshan Economic Development Zone. Our operating principle has not changed since day one:
Excellent quality. Trusted price. Customer first.




On the factory floor
“We replaced two manual grooving stations with one HR-1000. Corner-waste cleanup went from somebody’s full-time job to a bin change each shift.”
“Our greyboard is never perfectly square. The deviation correction is the reason we bought the 1300C, and it is the reason we bought a second one.”
“Knife set arrived in nine days. Their engineer walked our technician through the change on a WhatsApp video call at eleven at night, his time.”
