What capsule shell materials are compatible with the RG series softgel encapsulator?
Our softgel encapsulation machines process gelatin, HPMC (hydroxypropyl methylcellulose), and pullulan shell materials. Parameters including temperature, humidity, and dosing speed are fully adjustable for each material type. HPMC vegetarian capsule capability is standard on all RG-100, RG-300, and RG-500 models, supporting halal and kosher formulations.
Can one machine produce different capsule shapes and sizes?
Yes. By changing the die rolls, you can produce oval, oblong, round, cylindrical, and custom-shaped capsules. Die changeover takes 15-30 minutes with the quick-release mechanism, requiring no tools. Standard capsule size range is 5-24mm, with custom dies available for mini sizes (3-8mm) or large capsules up to 30mm.
What is the minimum batch size for softgel production?
For lab models (RG-100), minimum practical batch is 500 capsules. For production models (RG-300 and RG-500), minimum 2,000-5,000 capsules is typical. This makes the RG-100 at 5,000-10,000 caps/hour ideal for R&D, clinical trials, formulation development, and small-batch contract manufacturing operations.
Do you provide installation and operator training?
Yes, included at no extra cost. Our engineers provide 5-7 days on-site installation, commissioning, and operator training at your facility. We also offer free process trials at our Shanghai factory before equipment delivery, including formulation compatibility testing, capsule appearance evaluation, and production parameter optimization.
What certifications and documentation come with the machine?
Machines are CE certified and designed to cGMP, FDA 21 CFR Part 11, and ISO 9001 standards. Documentation includes material certificates (EN 10204 3.1/3.2), weld records, surface finish measurements, DQ/IQ/OQ/PQ protocols, calibration certificates, and operation manuals suitable for FDA, EMA, and Health Canada filings.
How much does a softgel encapsulation system cost?
The RG-100 lab model typically costs USD 15,000-25,000, the RG-300 production model ranges from USD 38,000-55,000, and the RG-500 industrial model costs USD 65,000-120,000. Final pricing depends on automation level, accessories, and certification requirements. Chinese machines offer 40-60% savings versus European brands.
What production capacity do you offer for different scales?
RG series ranges from 5,000 capsules/hour on the RG-100 lab model to 60,000 capsules/hour on the RG-500 industrial model. The RG-300 at 20,000-30,000 caps/hour is our most popular configuration for medium-scale manufacturing, with an optional high-speed upgrade reaching 40,000 caps/hour.
Which softgel machine model is right for my production scale?
For R&D and clinical trials, the RG-100 (5,000-10,000 caps/hour, min batch 500) is ideal. For medium-scale and contract manufacturing, choose the RG-300 (20,000-30,000 caps/hour, 850 kg). For 24/7 large-scale production, the RG-500 (40,000-60,000 caps/hour, 1,200 kg with auxiliaries) is recommended.
What is the filling accuracy of the precision dosing system?
Standard filling accuracy is +/-2% using servo-controlled gear pumps. An optional precision servo pump with flow meter achieves +/-1% accuracy. The system handles oils, suspensions, pastes, and semi-solids, with in-process weight control and auto-rejection of off-spec capsules per USP/EP standards.
What warranty and after-sales support do you provide?
We provide a 12-month warranty covering parts and labor, plus lifetime technical support. Remote diagnostics are available via TeamViewer and WhatsApp. Spare parts are shipped within 48 hours, and software updates are included for life. Preventive maintenance schedules and operator training are provided at no additional cost.
