How to choose a small bottle filling machine?

1. The oral liquid filling machine is specifically designed for small-volume liquids such as oral solutions, syrups, and beverages. It employs a piston/pump-driven system with high-precision dosing capability, compatible with volumes ranging from 2 to 100 mL, achieving filling accuracy within ±0.5%. Constructed entirely from 304/316L stainless steel, the unit meets GMP cleanroom requirements and features bottle-free filling, leak-proofing, and anti-bubbling functions. It operates smoothly with low noise levels, making it ideal for continuous production in pharmaceutical and health supplement manufacturing.

2. The vial filling machine is designed for high-cleanliness environments such as lyophilized preparations, injections, and biologics, integrating bottle handling, filling, stoppering, and capping into a single system compatible with 5–50 mL vials. It features servo-controlled filling volume regulation, supports nitrogen protection, laminar flow cleaning, and online weighing verification, meeting pharmaceutical GMP and sterile production requirements with excellent stability and low loss rates.

3. The powder filling machine is designed for pharmaceutical powders, probiotic powders, lyophilized powders, powder spices, etc., employing screw metering/weight-based dosing with dust-proof and anti-static features, achieving a filling accuracy of ±1%, and suitable for small-scale powder sub-packaging. It can be equipped with vacuum feeding and dust removal systems to address issues such as particle dispersion, wall adhesion, and layering, making it ideal for stable batch production of powders.

4. The essential oil filling machine is designed for high-value, small-volume materials such as essential oils, serums, and aromatherapy oils. It employs a precision micro-pump with anti-oxidation, leak-proof, and anti-bubbling features, compatible with 1–50 ml essential oil bottles or dropper tubes. Components in contact with the material are corrosion-resistant, ensuring stable dosing and eliminating waste, thereby meeting the stringent precision requirements of daily chemical and cosmetic applications.

5. The spray filling machine is suitable for pump-head products such as oral sprays, nasal sprays, moisturizing sprays, and disinfectant sprays. It integrates filling, pump head installation, and cap/rotary cap sealing functions, compatible with PET/glass spray bottles. Equipped with bubble prevention features, torque-controlled cap rotation, and air-tightness inspection capabilities, it ensures smooth spray flow without leakage.

6. The ampoule drawing and filling sealer is specifically designed for ampouled injections and sterile solutions, integrating filling, drawing, and sealing processes into a single unit. It ensures excellent sealing performance with no gas leakage or carbonization, complying with pharmaceutical sterilization standards and GMP requirements. Compatible with 1–20 mL ampoules, it serves as a critical piece of equipment in injectable production.

What should be done when the filling volume fluctuates significantly?
Calibrate the metering pump/sensor, inspect whether the sealing rings are worn, and adjust the filling speed and leak prevention parameters according to viscosity. Perform calibration once daily before startup.
How to address liquid leakage or material dripping from the filling machine?
Check the filling nozzle valve core and retraction function; replace aged sealing components; adjust the submergence depth and valve closure timing; and use a drip-proof filling head.
How should frequent bottle jams during production be addressed?
Check bottle dimensions, adjust the star wheel, bottle guide, and conveying speed; clean the sensors to ensure no deformed bottles enter the channel.
How to improve powder scattering and inaccurate dosing during filling?
Utilize screw metering combined with negative-pressure dust removal to optimize feeding speed, and install a level sensor and stirring device to prevent moisture-induced clumping.
How to address poor sealing or charred ends in ampoule drawing seals?
Adjust the gas mixture ratio, wire drawing speed, and flame position to ensure stable bottle positioning; regularly clean the flame and fixtures.
