The NJP-1200A automatic capsule filling machine delivers up to 1,200 capsules per minute with precise dosing, enclosed 10-station operation, automatic rejection, cleaning and capsule closing.
NJP-1200A Automatic Hard Capsule Filling Machine
The NJP-1200A is a fully automatic hard capsule filling machine developed for stable, high-speed pharmaceutical production. It is suitable for hard gelatin capsules and plant-based capsules, and can fill powder, granules, pellets, small tablets and other suitable solid materials. With a maximum output of up to 1,200 capsules per minute, the machine combines precise dosing, enclosed operation, automatic rejection, capsule closing and online cleaning in one integrated production platform.
The machine uses a compact rotary-table layout and a 10-station working cycle. Its tooling, cams, guide columns and dosing components are designed to support repeatable movement and consistent filling performance during continuous production. The enclosed structure also improves operator protection and helps maintain a cleaner production area.

10-Station Capsule Filling Process
- Capsule orientation, separation and loading: empty capsules are oriented and transferred into the segment while the cap and body are separated.
- Transition station: the capsule segment is positioned for the dosing process.
- Transition station: stable indexed movement prepares the tooling for material filling.
- Six-position dosing and tamping: material is metered and compacted to achieve the target fill weight.
- Transition station: the filled capsule bodies move toward inspection and rejection.
- Automatic rejection: improperly separated or non-qualified capsules are removed from the process.
- Transition station: accepted capsules are aligned for closing.
- Capsule closing: capsule caps and bodies are joined with adjustable closing force.
- Finished-capsule discharge: completed capsules are gently discharged using soft air.
- Tooling cleaning: the vacuum cleaning module removes residual material from the working area.
Engineering and Performance Features
- Precision motion system: precision-machined cams and a double-sided internal cam structure support smooth, repeatable movement at high operating speeds.
- Stable guided movement: individually supported guide columns help improve alignment and reduce the influence of accumulated mechanical error.
- Optimized dosing and dwell: the dosing section provides sufficient material compaction time for stable plug formation and consistent fill weights.
- Lightweight filling-pin support: an anodized magnesium-aluminum alloy support reduces moving mass while maintaining rigidity.
- Enclosed rotary platform: the enclosed structure separates the drive area from the product-contact working zone and supports easier cleaning and maintenance.
- Automatic rejection and cleaning: non-qualified capsules are removed automatically, while the cleaning station reduces material residue.
- Adjustable capsule closing: closing settings can be adjusted for different capsule specifications.
- Gentle discharge: soft-air ejection reduces impact on finished capsules during discharge.
- Operator-friendly controls: centralized control and clear status monitoring support setup, production and fault diagnosis.
Material Adaptability and Filling Consistency
Capsule formulations can vary considerably in flowability, bulk density, cohesiveness and sensitivity to compression. The NJP-1200A dosing system is designed to handle a broad range of pharmaceutical and nutraceutical materials. For powders with poor flow, sticky characteristics or a tendency to retain residue, the machine can be configured and adjusted to improve dosing stability and reduce leakage. The dosing depth, tamping arrangement, filling speed and vacuum conditions should be optimized during product trials according to the actual formulation.
Final output and filling accuracy depend on capsule size, material properties, target fill weight, tooling condition and operating parameters. We recommend sample testing for challenging formulations so that the appropriate tooling and process settings can be confirmed before delivery.
Vacuum System and Optional Supporting Equipment
The catalogue configuration includes a Becker KVT 3.80 oil-less rotary vane vacuum pump. Reference data include 2.4 kW motor power, approximately 80 m³/h nominal airflow, maximum vacuum of about 10 kPa, 1,420 rpm and a sound level of approximately 72 dB. Final auxiliary equipment selection is confirmed according to the project layout and production requirements.
Optional supporting equipment can include a vertical capsule polisher, QVC-2 vacuum conveyor, automatic empty-capsule feeder and JFP-110A capsule sorting and polishing machine. These options can create a more continuous capsule production line from material feeding to finished-capsule cleaning and sorting.
Applications and Configuration Notes
The NJP-1200A is suitable for pharmaceutical manufacturers, nutraceutical producers, contract manufacturing organizations and other facilities that require efficient automatic filling of hard capsules. It can be integrated with upstream material feeding and downstream polishing, metal detection, inspection and packaging equipment according to the production plan.
Machine configuration, capsule tooling, electrical standard, auxiliary equipment and validation documents can be discussed for each project. Capacity and process performance are based on suitable materials and correctly adjusted operating conditions. Please provide the capsule size, formulation type, target fill weight, required output and local power standard when requesting a quotation.
