For cosmetic filling lines, select the model based on the material, check the construction materials, and conduct a trial run with the actual product (Source: Industry experience): Liquids: Gravity filling at 100–300 bottles/minute (Source: Industry); Pastes: Rotary lobe pump or servo-driven piston (Source: Industry)—Key requirements: Product-contact parts made of 304/316 stainless steel + major-brand PLC (Source: Industry); trial run with actual product (Source: Industry).
I.
Model Selection Based on Material
Liquids: Toner/alcohol (gravity filling, single-head speed of 100–300 bottles/min; Source: Industry); Pastes: Face cream/lotion (rotary lobe pump or servo-driven piston with dual-speed control; Source: Industry); Tubes: Facial cleanser/serum (tube filling and sealing machine; Source: Urmachine); Powders: Loose powder (powder filling line); Viscous sauces/pastes: Clay masks (sauce/paste filling)—Material determines the pump type (rotary lobe pump vs. piston pump).
II.
Core Configuration
Materials: Product-contact parts made of 304/316 stainless steel (304 for the entire machine is preferable; Source: Industry); PLC: Major-brand electrical components for reliability (Source: Industry); Precision: Servo-controlled filling volume (Source: Industry); Cleaning: One-touch cleaning for hopper, piping, and filling valves (Source: Industry); Integration: Filling + capping + labeling + coding (Source: Xinghuo)—Configuration: 304 stainless steel + major-brand PLC (generic electrical components are prone to failure).
III. Representative Manufacturers
Xinghuo Machinery: 18-year history; 12-head liquid filling, capping, and labeling line (Source: Xinghuo); Hualian Pharmaceutical Machinery: Tube filling and sealing (CE/GMP certified; Source: Urmachine); TOM Intelligent: Rotary filling and capping for sunscreen lotion (Source: MIC); Ruike: Filling line for facial mask essences and creams (Source: Accio); Guangzhou Jijun: Direct manufacturer based in Guangzhou/Dongguan/Foshan (Source: Alibaba)—Key Manufacturers: Xinghuo/Hualian (covering both tubes and bottles).
IV.
Selection Criteria
1. Material (liquid/paste/powder); 2. Throughput/Cycle time (bottles/minute); 3. Precision (accuracy in ± grams); 4. Cleanliness (GMP workshop compatibility); 5. Compatibility (handling multiple bottle specifications)—Selection Logic: Material + Throughput + Precision (calculate production capacity first).
V. Supplier Evaluation
1.
Direct Manufacturer (avoiding middlemen; Source: Industry standard); 2. Trial Run with Actual Materials (testing with real products; Source: Industry standard); 3. After-sales Contract (warranty duration/24-hour on-site service; Source: Industry standard); 4. Certifications (CE/GMP/ISO; Source: Urmachine); 5. Case Studies (experience with similar product categories)—Evaluation Focus: Direct Manufacturer Status + Trial Run + After-sales Service (ensure inclusion in the contract).
VI. Common Pitfalls
“304” applies only to contact parts: non-contact parts may not be 304 stainless steel (Source: industry); “One-touch cleaning”: small machines often offer only basic cleaning (Source: industry); Low-cost, obscure-brand electrical components: high failure rates; No machine testing: risk of incompatibility with your specific product (Source: industry);
No after-sales terms: no guarantee for repairs—How to avoid: clarify material specifications, insist on machine testing, and verify contract terms.
VII. Procurement Recommendations
First, for liquid lines, choose gravity filling (high efficiency, low loss); second, for paste lines, choose servo-driven piston filling (high precision); third, for tube packaging, choose Hualian; fourth, for complete production lines, choose Xinghuo (12-head synchronized operation);
fifth, acceptance testing (yield rate and precision during machine trials)—For cosmetic filling lines: specify pump-type feeding, 304 stainless steel construction, and testing with actual product material (ensure after-sales terms are included in the contract).
