Every NJP filler quotes an output and a fill accuracy measured on a free-flowing test powder; your blend, capsule size and fill weight decide whether it holds that spread at half speed, or at all.
01
Most NJP machines use a dosing disc with tamping pins that press powder into slugs. It suits powders that form a plug. Fine, sticky or low-density powders may need a dosator or auger. Pellet and tablet dosing units are extras.
The segment holds capsules while they open, fill and close. Larger models add bores rather than index faster. Ask the bore count and the indexing rate at the quoted speed.
Each capsule size needs its own segments, dosing disc and tamping pins, and a new fill weight may need another disc. Count the sets in the offer and the price of one more.
A basic machine holds weight through disc thickness and pin depth, checked by an operator with a balance. An online checkweigher rejects every out-of-range capsule, and moves the price more than the frame does.
Ask where unopened or damaged shells go, whether they drop into a closed bin, and whether they are counted.
Powder in the cam box wears bearings and carries into the next batch. Check the dosing area is sealed from the drive, extraction is included, and contact parts are 316L with certificates.
A touch-screen PLC is standard. What differs is whether speed, rejects and alarms are logged with user levels. A supplement maker may manage with a counter; a licensed medicine maker needs an audit trail it can qualify.
02
Chinese fully automatic fillers are sold as NJP plus a number. On the manufacturer table we checked, the number is capsules per minute, and each size step adds segment bores. Letters after the number (C, D) are revisions and vary by factory; ask what they change.
03
Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

| Require this | A pass looks like |
|---|---|
| Fill your own blend in your capsule size at the speed you are buying. Weigh individual filled capsules, and empty shells from the same lot, from a counted sample taken at fixed intervals. | Net fill of every capsule inside your tolerance, with no widening of spread between the first and last sample. |
| Run at least one hour on your blend, refilling the hopper as in production. | No bridging, no pin build-up forcing a stop, and weight holds after each refill. |
| Feed a batch of shells including deliberately damaged and pre-closed ones. | Faulty shells are rejected to the reject bin and none reach the filled output. |
| Change over to your second capsule size while you watch. | Your operator could repeat it from the manual, and the time is written into the FAT record. |

A semi-automatic capsule filling machine: a fraction of the price, and less powder lost per change.
A tablet press can reach much higher output per machine with no shell cost per dose.
A softgel encapsulation line, or a liquid-fill machine with band sealing. A powder NJP will not seal a liquid.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Every machine we source in this area is on the Pharma & supplements page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
The intermittent-motion principle is similar. The difference is dosing on difficult powders, online checkweighing, dust sealing, recorded data and size-part supply. For supplements a Chinese NJP with a checkweigher can be enough. For licensed medicine, qualification papers often decide, and a used European filler is worth pricing.
Model and serial against the declaration, bore count and size parts against the order, steel certificates, reject function tested with faulty shells, your blend filled and weighed capsule by capsule, dust extraction running, and a timed size change.
Whether segments and dosing discs are machined in house, how pin wear is checked, and whether a machine can be shown filling real powder, not running empty.
