Production Process
  • Raw Material Selection & Testing (1)
    Adopt pharmaceutical-grade gelatin (plant-based raw materials for vegetable capsules) to control quality from the source; Raw materials undergo multiple inspections (purity, microorganisms, heavy metals, etc.) to ensure compliance with the Chinese Pharmacopoeia and GMP requirements. Unqualified raw materials are directly rejected.
  • Formula Preparation & Gel Making (2)
    Precisely adjust raw material formulas according to product specifications (00#, 00#B, 0#el, 0#, 1#, 2#, 3#, 4#, etc.) and customer customization needs (color, characteristics); Use automated equipment for the gel-making process, controlling key parameters such as temperature and viscosity to ensure a uniform and stable gel, guaranteeing capsule-forming quality.
  • Molding & Drying (3)
    The gel is dipped and formed through professional molds, which are strictly cleaned and disinfected to avoid cross-contamination. The formed capsule blanks enter a Class 100,000 clean room for gradient drying, with precise control of humidity and temperature to ensure the capsule moisture content meets standards and hardness is moderate.
  • Inspection (4)
    Adopt dual inspection (manual + machine): screen appearance (color, integrity), dimensional accuracy, and other indicators, reject unqualified products. Strictly conduct a full inspection of the physicochemical indicators for each batch.
  • Customized Processing (On Demand) (5)
    Provide exclusive color matching, printing (linear/circular printing), and other customized processing according to customer color card numbers and sample requirements; An additional sample confirmation link is added for customized products to ensure compliance with customer expectations before mass production.
  • Finished Product Packaging & Warehousing (6)
    Qualified finished products are packaged in clean (light-proof, moisture-proof) materials, marked with specifications, batches, and other information for traceability. Finished products are stored in a constant temperature and humidity warehouse, managed by zones to ensure stable quality during storage. Conduct final sampling inspection before delivery to ensure 100% compliance of delivered products.
