Quick Answer
What is a capsule filling machine?
A capsule filling machine is equipment that separates empty hard capsules, doses powder, granules, pellets, or liquid into the capsule body, then rejoins and locks the cap. HIJ's NJP-Series automatic capsule fillers run from 48,000 to 120,000 capsules per hour with ±2% dosing accuracy, handle sizes 00#–5# plus safety capsules A–E, and use 316L stainless steel contact parts in a cGMP-ready, CE-marked design.
Key Takeaways
- Match the machine to your scale: lab/R&D batches suit a small or semi-automatic filler; commercial production from 48,000 capsules/hour and up calls for a fully automatic NJP-Series machine.
- Match the dosing system to your material: tamping-pin dosing suits free-flowing powders and granules; dosator and liquid-pump systems handle cohesive powders, oils, and suspensions.
- Verified NJP performance: ±2% filling accuracy, >99% capsule separation rate, capsule sizes 00#–5# and safety A–E, size-only changeover in 20–30 minutes.
- Compliance done right: HIJ equipment is cGMP-ready and CE-marked, built to ISO 9001 manufacturing standard, and ships with DQ/IQ/OQ documentation that supports your validation program — we never claim self-certification.
- Think in lines, not machines: a capsule filler pays off fastest when integrated with polishing, capsule blister packing, and cartoning in one turnkey project.

Forester's Insight
Founder & Chief Engineer, HIJ Machinery
The most common mistake I see buyers make is choosing a capsule filler purely on rated speed. A machine's brochure speed means nothing if your powder bridges in the hopper or your team spends two hours on every changeover. The right question is not "how fast can it run?" but "how fast can it run with my formulation, my capsules, and my operators?"
That's exactly why we insist on a Factory Acceptance Test with your actual product before shipment. When you watch your own powder filling at rated speed with weight data on the screen, the decision stops being a gamble. If a supplier won't run FAT with your product, that tells you everything you need to know.

Expert Answers
Capsule Filling Machine FAQ
The questions buyers ask most before choosing an encapsulation machine — answered by Forester Xiang.
What is a capsule filling machine and how does it work?
A capsule filling machine separates empty hard capsules into cap and body, doses powder, granules, pellets, or liquid into the body, then rejoins and locks the two halves. Automatic machines like the HIJ NJP-Series complete orienting, separating, filling, faulty-capsule rejection, and closing in one continuous rotary cycle, producing 48,000 to 120,000 finished capsules per hour with ±2% dosing accuracy.
What is the difference between tamping pin and dosator dosing technology?
Tamping pin systems compress powder into a dosing disc in stages before transferring the slug into the capsule, which suits free-flowing powders and granules with predictable flow. Dosator systems draw a measured slug of powder directly into a cylinder, which handles cohesive, sticky, or poorly flowing materials common in herbal and nutraceutical formulations. HIJ machines can be configured with either system, and we run free powder trials with your formulation to confirm the right choice before purchase.
How fast is an automatic capsule filling machine?
HIJ's NJP-Series automatic capsule fillers produce 48,000 capsules per hour on the NJP-800, 72,000 per hour on the NJP-1200, and 120,000 per hour on the NJP-2000. Semi-automatic machines typically run up to about 25,000 capsules per hour, while small lab-scale units are designed for R&D and pilot batches rather than continuous output. All NJP models handle capsule sizes 00# to 5# plus safety capsules A to E.
How long does a capsule size or product changeover take?
A size-only changeover on an NJP-Series machine takes 20 to 30 minutes using tool-free, quick-change format parts. A complete product changeover, including dismantling, cleaning, sanitization, and setup of the new recipe, typically takes 45 to 60 minutes. Machine parameters are stored digitally, so repeat products can be recalled instantly without re-calibration from scratch.
What documentation do you provide to support validation (DQ/IQ/OQ/PQ)?
Every HIJ capsule filling machine ships with a documentation package designed to support your own qualification program: Design Qualification (DQ) specifications, Installation Qualification (IQ) checklists with 316L material certificates and calibration records, Operational Qualification (OQ) test protocols, and Performance Qualification (PQ) templates for your product-specific runs. Your team executes the validation; our documentation and on-site engineers support it, including a Factory Acceptance Test performed with your own products before shipment.
What is the lead time for a capsule filling machine?
A standard-configuration machine typically ships 10 to 12 weeks after deposit, including manufacturing, assembly, and Factory Acceptance Testing. Custom configurations with specialized tooling or containment options generally take 14 to 16 weeks, and complete turnkey lines with polishing, checkweighing, and packing integration take 16 to 20 weeks. We recommend ordering 4 to 6 months before your planned production start to allow for shipping, installation, and operator training.
