Overview
Built around your product
This variant shares the DA-8000 platform — Siemens PLC control, Inovance servo drive, 6 kW drive and 30–60 fastenings per minute — and adds a female-buckle die with an additional hydraulic cylinder. One machine therefore produces both halves of the clasp set: male buckles and female buckles, in the same 50 mm strip and 5–12 mm panel range. The standard DA-8000 produces male buckles only; choose this variant when the box design needs the full male–female fastening set from a single machine. Two automatic steel strip decoilers are included as standard — one per die station.

WORKFLOW
Standard operating sequence
Panel positioning
The panel is clamped and aligned accurately with the die.
Dual fastening
Male and female buckles are formed and fastened in sequence by the two die stations.
Reset & transfer
The punches reset and the workpiece advances to the next cycle.
OPERATION GUIDE
How to operate
Check and test-run
Inspect guards, chains, dies and feed tracks, and match the male and female dies to the buckle set. Run the machine empty for 1–2 minutes and confirm smooth, quiet operation.
Load the steel strip
Place the matched steel strip in the dies with the correct orientation. Keep both feed tracks clear — no stacking, no jammed buckles.
Position the panel
Lay the plywood panel flat on the worktable and align the fastening point with the center of the die. Hold the panel steady so it cannot shift.
Form both buckle halves
Press start: the two die stations form and fasten the male buckle and the female buckle in sequence, then reset automatically.
Repeat and inspect
Move the box through each fastening point at a steady pace. Check every clasp: buckles flat, tight and matched, with no cracks or dents in the panel.
Shut down and clean
Run the machine empty for 10–20 seconds to clear the tracks, then stop and power off. Clean the table, tracks and dies, and record the run.
Safety: keep hands out of the pressing, feeding and transmission zones while the machine runs. Stop immediately on jamming, unusual noise or a mis-fastened buckle — never run a faulty machine.
