Changzhou Hongxinyutai Precision Mold Co., Ltd., a dedicated manufacturer established in 2017, proudly presents our Two-Piece Bottle Cap Mold Tooling: 1*16 Cavities, S136 Steel, IATF 16949. Designed for high-volume production of plastic bottle caps, this mold combines precision engineering with durable S136 steel to ensure long service life and consistent output. Our factory, spanning 1,000–3,000 square meters with a skilled team of 51–100 employees, is fully equipped to deliver tooling that meets the rigorous standards of the packaging industry.
This mold tooling is specifically engineered for two-piece bottle cap designs—typically a cap and a liner—optimized for injection molding machines. With 16 cavities arranged in a single row (1x16), it offers a balanced production rate while maintaining excellent part quality. The use of S136 steel (comparable to DIN 1.2083) provides superior corrosion resistance, high hardness, and excellent polishability, making it ideal for caps requiring a glossy finish. All manufacturing processes are conducted under quality management principles aligned with IATF 16949 standards, ensuring traceability and consistency.
Key Features & Technical Specifications
- High Cavitation Efficiency: 16 cavities per cycle maximize output per shot, reducing per-part cost.
- Premium Steel Quality: S136 steel offers hardness up to 48-52 HRC, excellent wear resistance, and low maintenance.
- Precision Two-Piece Design: Integrated core, cavity, and stripper plate ensure accurate sealing and easy demolding.
- Advanced Cooling System: Conformal cooling channels minimize cycle time and reduce part warpage.
- Hot Runner or Cold Runner Options: Customizable gate design based on your preference (submarine, side gate, or valve gate).
- IATF 16949 Compliant Process: Documented quality control from design to trial and shipping.
- Quick Change Feature: Interchangeable cavity inserts allow fast mold changeover.
