1. Injection molding – High-precision machines create consistent cap shapes from LDPE or HDPE materials.

2. Two-color molding – Many modern caps combine soft TPE for sealing and rigid plastic for durability.

3. Cleanroom assembly – To ensure hygiene, caps are produced and assembled in controlled environments without human contact.

4. Automated inspection – Vision systems detect defects, guaranteeing 100% quality.

5. Labeling & packaging – Caps are labeled and packed using fully automated equipment.
   This process ensures that Bottled water bottle caps meet the highest hygiene standards, making them safe for use in beverages, healthcare, and even sensitive laboratory settings.
