The Five Decisions That Define Your Capsule Filler

1. Automation Level: Manual Board vs Semi-Automatic vs Fully Automatic

Verdict: Match automation to volume and consistency demands. Manual boards suit labs and clinics; semi-auto (like CGN-208D) bridges manual to industrial scale; fully automatic NJP series enables continuous mass production.

2. Capsule Size Coverage: 000#–4# vs 00#–5# & A-E Safety

Verdict: Manual boards and CGN-208D cover up to 4# only. The NJP series expands to 00#–5# and supports A-E safety capsules — essential for regulated markets requiring enhanced integrity.

3. Output Tier: Hundreds to 150,000 Capsules/Hour

Verdict: Manual systems yield variable outputs (typically a few hundred to thousands per session). CGN-208D delivers 10,000–30,000/hr. NJP models scale from 12,000/hr (NJP-200) to 150,000/hr (NJP-2500).

4. Material & Construction: SUS304/SUS316L vs Plastic/Acrylic

Verdict: Plastic/acrylic boards (e.g., 100-hole blue plastic, 400-hole clear plastic) are cost-effective for low-volume use. SUS304 is standard for all semi-auto and auto machines; upgrade to SUS316L for GMP/FDA facilities handling aggressive formulations.

5. Line Integration: Feeder, Polisher, Sorter, Counter

Verdict: Full automation (NJP series) seamlessly integrates with vacuum feeders, capsule polishers, sorters, and counters. Semi-auto machines like CGN-208D can be paired with downstream units for batch-level efficiency gains.

Capsule Size & Format Coverage

Capsule compatibility is non-negotiable. Choose based on your formulation and regulatory requirements:

  • Manual Boards & CGN-208D: Support capsule sizes 000# to 4#. These are standard sizes used in most supplements and pharmaceuticals.
  • NJP Series: Covers 00# to 5# and includes support for A-E safety capsules, which are designed to resist tampering and ensure integrity in sensitive applications.

For facilities handling multiple formats or aiming for global distribution, the NJP series is the only viable option. Manual systems cannot accommodate larger sizes or safety variants.

Automation & Controls — Precision Meets Reliability

Control systems determine uptime, consistency, and ease of operation:

  • CGN-208D: Equipped with a Siemens PLC + HMI + VFD system, plus Schneider breakers and OMRON relays. Ensures stable power delivery and responsive control. One-button capsule locking reduces operator error.
  • NJP Series: Features PLC touchscreen control with stepless variable-frequency drive (VFD), enabling smooth speed adjustments across production runs. Servo-driven turntable ensures precise alignment and consistent fill depth.

Both semi-auto and auto models offer 5–8 minute mold change times (CGN-208D) and 100% capsule separation during operation — critical for preventing cross-contamination and ensuring full yield.

Line Integration: Feeder, Polisher, Sorter, Counter

Maximize throughput and quality by integrating downstream equipment:

  • Vacuum Feeder: Automatically supplies capsules to the filling station. Recommended for CGN-208D and all NJP models.
  • Capsule Polisher: Removes dust and debris post-filling. Essential for premium cosmetic and pharmaceutical products.
  • Capsule Sorter: Identifies and removes defective or misaligned capsules. Improves final product quality.
  • Capsule Counter: Automates counting for packaging and inventory tracking.

These units integrate seamlessly with the NJP series and can be added to semi-automatic setups like CGN-208D for end-to-end process control.

Material & Compliance — Building for GMP and FDA Standards

Material choice affects both hygiene and longevity:

  • SUS304 Stainless Steel: Standard across all semi-automatic and fully automatic machines. Resists corrosion and meets basic GMP requirements.
  • SUS316L Stainless Steel: Available as an upgrade for material-contact parts on all NJP series machines. Superior resistance to strong acids, alkalis, and high-temperature sterilization — ideal for FDA-compliant facilities and high-purity formulations.

Plastic and acrylic boards (e.g., 100-hole blue plastic, 400-hole clear plastic) are not suitable for GMP environments due to surface porosity and cleaning limitations.

Choose SUS316L if your facility handles potent actives, hormonal compounds, or requires third-party audit readiness.

Budgeting & ROI — What Drives Price and What You Get Back

Costs vary significantly across automation tiers:

  • Manual Boards: $150–$600 depending on hole count and material (acrylic = higher cost).
  • CGN-208D: Mid-range investment (~$25,000–$35,000). Delivers ROI within 6–12 months for operations producing 15,000+ capsules/month.
  • NJP Series: Higher upfront cost ($40,000–$120,000+), but justified by:
  • 24/7 production capability
  • Reduced labor per unit
  • Lower defect rates (99%+ loading rate)
  • Scalability from pilot to full line

ROI accelerates when combined with integrated feeder/polisher/counters. Consider total cost of ownership — not just purchase price.
