SF3203 SINGLE-MOLD STEEL STRIP BUCKLE MACHINE — Entry-Grade · 32-40 Buckles/min · Siemens + Yaskawa

The entry price point into the HICAS nailless-plywood-box buckle family. Produce one buckle type at a time with premium Siemens + Yaskawa control — for producers who don't yet need the male+female double-mold throughput of the SF3204.

Siemens ST40 PLC + 5.7" touchscreen · Yaskawa (Japan) servo · 2× Pepperl+Fuchs (Germany) sensors · Schneider electrics · Hydromax + YUKEN + Shenyu hydraulic stack · HICAS auto decoiler.

- 32-40 buckles per minute at 20 m/min panel feeding
- Single-mold design — one buckle type per setup
- Dual voltage 220V/380V — fits most European, Asian and Latin American power grids
- Same Siemens ST40 + Yaskawa servo as the higher-end SF3204
- Video outgoing-inspection + machinery test report before shipment

SF3203 completes the entry-grade version of the HICAS nailless plywood box product family:

- SF3302 — produces the double-hole steel-strip frames that form the box structure
- SF3103 — wraps the steel strip around the plywood corners for reinforced folding edges (3-4 m/min)
- SF3203 (this machine) — produces the single-type buckles that lock the folded box shut (32-40 buckles/min)

All four HICAS nailless-box machines (SF3302 / SF3103 / SF3203 / SF3204) run on the same Siemens PLC + Yaskawa (Japan) servo + Pepperl+Fuchs (Germany) sensors + Hydromax/YUKEN/Shenyu hydraulic architecture — a consistent premium component stack.

1.ENTRY POINT INTO THE BUCKLE FAMILY: SF3203 is the entry-grade single-mold option — the lowest-cost way into the HICAS nailless-box buckle production family, with the same premium control brands as the top-of-range SF3204.

2.SIEMENS ST40 PLC AT ENTRY PRICE: Not a generic PLC — the ST40 module is Siemens' high-speed input/output series, sized for real-time buckle-cycle control at 32-40 cycles/minute, at an entry-grade machine price.

3.YASKAWA (JAPAN) SERVO: Japanese Yaskawa servo drives the buckle stamping and feeding cycles — the same premium servo brand European premium machine builders specify.

4.GERMAN PEPPERL+FUCHS SENSING: 2× Pepperl+Fuchs (Germany) precision sensors drive accurate position detection at every stage.

5.PREMIUM HYDRAULIC STACK: Taiwan Hydromax pump + Japan YUKEN valves + Taiwan Shenyu motor — the same industrial-grade hydraulic system used across SF3103, SF3204 and SF3302.

6.VIDEO INSPECTION BEFORE SHIPMENT: Every SF3203 ships with a video outgoing-inspection and a machinery test report — you see the machine running before it leaves our floor.

Choose SF3203 when you're entering the nailless-box market or producing one buckle type at a time; upgrade to SF3204 for the double-mold interlock-buckle production of the higher-throughput interlock-box workflow. Both share the same Siemens + Yaskawa + Pepperl+Fuchs + Hydromax/YUKEN stack — a consistent premium architecture across the whole HICAS buckle range.

For small and mid-sized nailless-box producers, buying buckles from external suppliers eats margin and risks supply gaps. SF3203 lets you enter in-house buckle production at the lowest HICAS price point — with the same premium components as the top of the range and video-verified shipment quality.

What this means for you:

- Enter in-house buckle production at the lowest HICAS price point
- 32-40 buckles/minute continuous — production-grade throughput even at entry scale
- Premium Siemens + Yaskawa + Pepperl+Fuchs components — no compromise on quality-tier
- Video-verified quality before the machine even leaves our floor
- Upgrade path to SF3204 double-mold as your interlock-box volume grows

Q: What does the SF3203 do?
A: It produces metal buckles from SGCC steel strip — the buckles used to lock nailless foldable plywood boxes shut. The single-mold design produces one buckle type per setup.

Q: How is SF3203 different from SF3204?
A: SF3203 is the single-mold entry-grade version (one buckle type per setup, 2 sensors, 1,000 kg); SF3204 is the double-mold version (male + female in one cycle, 4 sensors, 1,200 kg). Both share the same Siemens ST40 + Yaskawa servo + Pepperl+Fuchs + Hydromax/YUKEN hydraulic architecture.

Q: How fast is it?
A: 32-40 buckles per minute, with 20 m/min panel feeding.

Q: What steel strip and plywood does it use?
A: SGCC steel strip 50 × 0.7 mm (tolerance ±0.05 mm), for plywood 5-10 mm thick (9 mm buckle tooth length).

Q: What control system does it use?
A: Siemens ST40 PLC with high-speed input/output terminals, and a Siemens 5.7" touchscreen.

Q: What servo and sensors are fitted?
A: Yaskawa (Japan) servo and 2 × Pepperl+Fuchs (Germany) precision sensors.

Q: What voltage does it use?
A: Dual voltage as standard: 220V or 380V, 50Hz, 3-phase — no reconfiguration for most markets.

Q: Do you inspect the machine before shipment?
A: Yes — every SF3203 ships with a video outgoing-inspection and a full machinery test report, so you see the machine running before it leaves our floor.

Q: How does SF3203 fit with SF3302 and SF3103?
A: SF3302 makes the steel-strip frames; SF3103 wraps steel strip around plywood corners; SF3203 (or SF3204) makes the buckles that lock the box shut. Together they form a complete nailless-plywood-box workflow.

Q: What's the lead time?

A: 30-50 days from confirmed order.

Q: What payment terms do you accept?
A: 30% T/T deposit, LC at sight, and SINOSURE export credit insurance.
