High-Speed Fastener Packaging Machine for Screws, Nuts & Bolts
Empowering global fastener manufacturers, hardware suppliers, and automotive assembly lines with intelligent multi-bowl optical counting, high-precision weighing, and fully automated bagging solutions. Achieve zero-error hardware packaging with up to 120 bags per minute throughput.
Eliminating Production Bottlenecks in Fastener Packaging
In industrial assembly, ready-to-assemble (RTA) furniture kits, electrical construction, and automotive fastener manufacturing, packaging errors cause catastrophic assembly line delays and costly customer chargebacks. Ludyway designs ruggedized fastener packaging machines engineered specifically to overcome severe hardware packaging hurdles.
High-Speed Optical Counting
Manual counting of small screws, dowel pins, and lock nuts is slow and prone to human error. Ludyway integrates multi-angle infrared and optical fiber sensor eyes that detect items flying at millisecond speeds, ensuring 100% accurate count per bag.
Multi-Hardware Mixed Kitting
Assembly packs demand mixed combinations (e.g., 4 screws, 4 wall anchors, 2 Allen wrenches, 4 flat washers). Our synchronized multi-feeder lines feed distinct parts simultaneously into a centralized collector bucket without cross-contamination.
Abrasion-Proof Engineering
Sharp metal threads and heavy carbon steel bolts rapidly damage standard packaging channels. Ludyway utilizes high-grade PU polyurethane coating on vibratory bowls and hardened 304/316 stainless steel chutes to minimize noise and eliminate surface wear.
Smart Rejection & Verification
Every completed packet passes through high-precision dynamic checkweighers. Any pouch deviating by even a single gram or component count is instantly rejected off the conveyor via pneumatic air-blast into a dedicated quarantine bin.

Built with industrial-grade electromechanical integration, our hardware packaging machinery ensures non-stop 24/7 reliability even under aggressive heavy-vibration plant conditions.
Custom Vibratory Bowl Feeders & Linear Tracks
Each feeder bowl is tailored to fastener geometry (length, head diameter, thread profile). Electromagnetically tuned linear tracks orient parts in a single-file continuous stream, preventing jams and overlap.
High-Speed Fiber-Optic & Laser Counting Gates
As screws drop past the optical gate, microsecond photo-sensors register individual signals. When target counts (e.g., 50 pcs) are reached, high-speed pneumatic flaps divert excess items seamlessly back to the bowl.
Vertical Form-Fill-Seal (VFFS) Bagging Station
Film roll stock (PE, laminated OPP/CPP, aluminum foil) is pulled via dual servo belts, formed into tubular pouches, cross-sealed with heavy-duty heat jaws, and severed with precision serrated blades.
Integrated Thermal Transfer Overprinter (TTO)
Directly prints sharp dynamic barcodes, QR codes, batch numbers, part diagrams, and multilingual text directly onto the packaging film before sealing.
PLC Touchscreen with Recipe Memory
Siemens or Delta PLC touchscreen interface storing over 200 hardware packaging recipes. Switch product runs with one tap—automatically adjusting bowl speed, bag length, and drop intervals.

Frequently Asked Questions on Fastener Packaging Automation
Find clear technical answers regarding hardware counting accuracy, oily screw handling, mixed kit synchronization, and changeover protocols.
Q. How does the machine handle oily, coated, or black oxide fasteners without clogging?
Fasteners often retain anti-rust oils, zinc plating residue, or phosphating dust. Ludyway equips vibratory bowls with specialized oil-drain grooved linings and non-stick polyurethane (PU) sprays. Optical sensors feature high-penetration infrared emitters and automatic compressed-air purging nozzles that prevent sensor lenses from being blinded by oil vapor.
Q. Can a single packaging line handle mixed hardware kits with 6+ different components?
Yes. Our modular kitting lines (LW-FP Series) integrate up to 16 individual vibratory counting bowls aligned along a continuous conveyor bucket line. Each bowl counts its designated component (e.g., Bowl 1: 8x M6 screws; Bowl 2: 8x nuts; Bowl 3: 16x flat washers; Bowl 4: 1x hex key). All parts dump synchronously into a central pouch before VFFS heat-sealing.
Q. What packaging materials and film thicknesses are supported for heavy hardware?
Sharp fastener threads and heavy bolts can pierce standard thin films. Ludyway machines handle heavy-gauge polyethylene (PE), OPP/CPP, PET/PE, and multi-layer laminated barrier films ranging from 45 microns to 150 microns. Constant-temperature heavy-pressure sealing jaws guarantee ultra-strong cross seals that withstand drops and puncture.
Q. How long does changeover take when switching screw lengths and diameters?
Tool-free mechanical adjustments take under 10 minutes. Linear tracks feature quick-release micrometer width knobs to accommodate screws from M2 up to M16. On the PLC touchscreen, operators simply select the pre-saved product recipe to instantly recalibrate optical drop frequencies and target bag sizes.
Q. What happens if a screw gets stuck or an incorrect count is dispensed?
The system features dual-layer fail-safe verification. First, the optical counter detects irregular drop timing and alerts the PLC. Second, an inline downstream high-precision checkweigher weighs every sealed packet. Any pack missing even a single washer or screw is automatically blown off the conveyor into a locked reject box without stopping machine production.
