Production capacity should be evaluated by both pieces per minute and kilograms per hour. Actual mass output varies significantly with nail diameter and length, so a fixed tons-per-shift figure should not be applied to every nail specification.
Request D70 Machine PricingThe D70 continuously feeds steel wire into the nail-forming mechanism, controls the required nail length, forms the nail head and cuts the wire to create the finished nail and point. Repeated mechanical cycles allow high-speed automatic nail production.
Steel wire of the required diameter is supplied from the pay-off system and fed into the machine. Nail diameter is primarily determined by the incoming wire diameter.
The machine is adjusted for the required nail length within the supported 25–70mm range. Changing nail specifications may require machine adjustment and corresponding tooling.
The punch and forming components create the nail head according to the configured tooling. Head geometry depends on the mould and punch specification used for production.
The nail knife cuts the wire to length and forms the nail point. Cutter condition and setup influence point consistency and finished nail quality.
Finished loose nails are discharged from the nail machine for collection, polishing, inspection, packing or subsequent collating according to the production process.
The D70 has a rated speed of up to 850 nails per minute. Actual operating speed and finished output can vary with wire quality, nail diameter, nail length, tooling condition, machine setup and production requirements.
One D70 machine can produce multiple nail lengths within the 25–70mm range by adjusting the machine and installing the corresponding tooling.
The machine accepts steel wire from 1.8mm to 2.5mm in diameter. The incoming wire diameter determines the basic shank diameter of the finished nail.
The D70 uses a 7kW motor with standard AC 380V power configuration. Buyers should confirm local voltage, frequency and electrical requirements before ordering.
KYA lists high-grade steel shaft, cam and gear components with professional heat treatment. These components form the core mechanical transmission system used during continuous high-speed operation.
The current D70 specification lists 32# gear oil for lubrication. Correct lubrication and maintenance are important for transmission components and long-term machine operation.
Nail moulds, nail knives and punch pins are key tooling components. Different nail specifications can require matching tooling, and these parts should be treated as setup and wear components during factory production.
The D70 is primarily a wire nail forming machine. It produces loose steel nails within its supported diameter and length range.
| Finished / Downstream Product | D70 Role |
|---|---|
| Common Wire Nails | D70 produces the loose finished nail directly |
| Loose Construction Nails | Can be produced within the supported size range and tooling configuration |
| Coil Nails | D70 produces the individual nails; a separate coil nail collating machine is required to weld or collate them into coils |
| Paper Tape Strip Nails | D70 produces the individual nails; separate paper collating equipment is required for finished strips |
| Threaded / Ring Shank Nails | Additional thread-rolling or shank-forming equipment may be required depending on the nail specification |
Nail-machine capacity should not be evaluated using only a tons-per-shift figure. A machine operating at the same pieces-per-minute rate will produce very different kilograms per hour when changing from a short 1.8mm nail to a longer 2.5mm nail.
| Capacity Factor | Effect on Output |
|---|---|
| Machine Speed | Determines nominal pieces produced per minute |
| Wire Diameter | Larger diameter increases the weight of each nail |
| Nail Length | Longer nails increase individual nail weight |
| Operating Efficiency | Tooling changes, wire changes, inspection and maintenance reduce theoretical continuous output |
| Material Quality | Wire consistency can affect running stability and finished nail quality |
For an accurate production-capacity calculation, provide the target nail diameter, nail length and required daily working hours. Capacity can then be estimated in both pieces and kilograms or tons.
Traditional wire nail machines in the 25–70mm class are commonly offered at substantially lower piece-per-minute speeds. For example, conventional machines in this size range are available around 280 nails/min, while current high-speed designs can reach approximately 750–850 nails/min depending on model and nail specification.
| Comparison | High-Speed D70 | Conventional Machine |
|---|---|---|
| Rated Speed | Up to 850 pcs/min | Often substantially lower depending on model |
| Production Strategy | High-volume continuous nail production | Suitable where lower investment or lower required output is acceptable |
| Factory Planning | Higher upstream wire consumption and downstream handling capacity required | Lower material-flow requirement |
| Selection | Compare actual nail size, kg/hour, energy use, tooling cost, maintenance requirements and production stability instead of speed alone. | |
Nail length can be adjusted within the machine's supported range. Nail diameter is changed by feeding the corresponding wire diameter, while the relevant forming tools must match the required finished nail geometry.
| Tool / Setting | Function |
|---|---|
| Nail Mould / Die | Supports nail gripping and forming for the specified diameter |
| Punch Pin | Forms the nail head according to the required head geometry |
| Nail Knife / Cutter | Cuts the wire and forms the nail point |
| Wire Diameter | Determines the basic nail shank diameter |
| Length Setting | Controls the required finished nail length |
When ordering multiple nail specifications, provide a complete size list so the required moulds, cutters, punches and changeover requirements can be confirmed before machine production.
The current KYA D70 page lists an active pay-off stand with approximately 1.5-ton capacity and controller. The pay-off system supplies wire continuously to the nail machine and is an important part of stable high-speed production.
A complete nail factory may also require wire preparation, nail polishing, inspection, weighing, packing and optional downstream collating equipment. Buyers should confirm which equipment is included in the D70 quotation and which equipment is supplied separately.

Maintain the lubrication system using the specified oil and follow the machine maintenance schedule. Insufficient lubrication can increase wear on moving and transmission components.
Inspect the nail knives regularly for wear because cutter condition influences the nail point and cutting consistency.
Punch pins and nail moulds are production tooling and should be inspected for wear, alignment and dimensional accuracy as part of routine maintenance.
Stable wire supply and consistent incoming wire diameter help maintain production stability and nail dimensional consistency.
The current KYA specification lists a rated production speed of up to 850 nails per minute. Actual continuous production speed can vary with nail size, wire quality, tooling and operating conditions.
The D70 supports nail lengths from 25mm to 70mm and steel wire diameters from 1.8mm to 2.5mm.
Yes, 2.5mm wire diameter and 50mm nail length fall within the current D70 specification. The required nail mould, punch and cutter must be configured for the target nail.
There is no single accurate tons-per-shift figure for every nail size. Mass output depends on nail diameter, nail length, actual operating speed and production efficiency. Provide the target nail specification for a meaningful kg/hour or tons/shift calculation.
850 pcs/min is the current rated maximum speed. Actual working speed can vary according to nail dimensions, wire material, machine setup, tooling condition and required quality.
The current specification lists a 7kW motor.
The standard KYA specification lists AC 380V three-phase power. Buyers using a different local electrical standard should confirm available machine configuration before ordering.
The current machine dimensions are approximately 1850 × 1100 × 1100mm and net weight is approximately 3200kg.
Yes. Nail length can be adjusted within the supported range, while different wire diameters and nail geometries require the corresponding wire and tooling setup.
The D70 makes individual wire nails. Producing finished wire-collated coil nails requires a separate coil nail collating machine after nail forming.
The D70 can produce the individual nails used as feedstock, but a separate paper tape nail collating machine is required to produce the finished paper-collated strip.
Typical tooling includes the nail mould, punch pin and nail knife. The exact tooling specification depends on nail diameter, head profile, point and other product dimensions.
KYA currently specifies 32# gear oil for the D70 lubrication system.
The current KYA page lists an active pay-off stand with approximately 1.5-ton capacity and controller. Buyers should confirm the exact standard machine scope and included accessories on the final quotation.
