Application Capsule Types
1. The machine is compact, uses little energy, and is easy to operate and clean.
2. Standardized parts allow for easy and accurate mold changes.
3. It has a bottom-mounted cam with a pressurized oil pump that keeps the cam groove lubricated, reducing wear and extending parts’ life.
4. A high-precision indexer reduces vibration and keeps noise under 80 dB. The vacuum system ensures over 99.9% capsule feeding success.
5. The filling amount can be adjusted in three directions based on the dosing disk’s lower surface, ensuring even filling and easy cleaning.
6. The control panel is user-friendly and has many features. It automatically sounds an alarm and stops production if there is a shortage of material or capsules or if there is a blockage. It also shows the dose for each capsule and total production in real time.

The NJP-400 is a high-speed machine. Its theoretical output is up to 400 capsules per minute, though the actual speed can vary based on the powder characteristics and operator skill.
The NJP-400 can be easily adjusted to fill all standard capsule sizes:Â Size 00, 0, 1, 2, 3, 4, and 5. You need to change the corresponding parts in the dosing disc, the rectifying ring, and the cap and body bushings.
It is designed for free-flowing powders. It can also handle:
Granules
Semi-flowing powders (may require a paddle feeder attachment for consistent filling)
It is not suitable for non-flowing, sticky, or highly oily formulations without significant modification and expert tuning.
Yes. The NJP-400 is built with GMP (Good Manufacturing Practice) requirements in mind. Key features include:
Contact parts made of SS 304 or SS 316 stainless steel.
Easy-to-clean design with minimal dead spaces.
A fully enclosed safety guard with interlocks (the machine stops if the guard is opened during operation).
 It typically runs on a standard 220V/380V, 50/60Hz power supply. Always check the manufacturer's specifications for your specific model and region.
For a skilled operator, a complete changeover (e.g., from size 0 to size 2) typically takes 20-30 minutes. This includes changing the bushings, dosing disc, and rectifying ring, and recalibrating the fill weight.
Fill weight is adjusted primarily in two ways:
Dosing Disc Thickness:Â You physically change the dosing disc to one with a different thickness (e.g., 4mm, 6mm, 8mm). A thicker disc gives a heavier fill.
Powder Bed Height:Â The machine has a knob to adjust the height of the powder in the feeding hopper, which indirectly affects the fill weight and consistency.
Tamper Settings:Â Some models have tamping pins that can be adjusted to compress the powder for higher weight and density.
It is prudent to keep:
Gaskets and Seals:Â Wear-and-tear items that need frequent replacement.
Dosing Discs:Â A full set for the capsule sizes you use.
Bushings (Cap & Body):Â At least one set for each capsule size you use.
Rectifying Rings:Â One for each capsule size.
Drive Belts:Â Standard V-belts that can wear out.
