Cylindrical Sample Vial With Plastic Screw Cap Vial and Tamper-Evident Break Ring

Our production lines make plastic screw-cap vials designed to retain important features. This plastic screw cap vial is routed with controlled thread standard and material grouping to ensure consistent surface finish. For the part, we set thread standard, material grouping, and surface texture checkpoints into the routing; process checks align to released documentation and reference samples to verify each stage. We use a dimensioned print with callouts or a reference sample for fit and inspection. Industries served include medical equipment, food & beverages, and packaging. Weilong Technology's Changzhou site is ISO 9001–certified and supplies automated filling lines. Operating since 2003, the plant handles series production. Quoted price reflects material choice and order quantity.
