|
specially designed cooling circuits |
Proper design reduce molding cycle time to 15 seconds( with proper water chiller and injection machine) about 3-5 shots per minute |
|
Hot runner design |
make sure the high quality of preform products. |
|
Heater |
Anole Germany |
|
valve gated design with Automatic drop |
each cavity has its independent heating zone and temperature is measured by independent thermocouple.(advantages: easily avoid some problems such as white or draw bench on bottom). Valve gated type without tail reduces labor force. |
|
Precessed by high presion CNC machine and numerical control loathe machine |
Lowest weight and dimensional variation thickness between max. part and min. part is not more than 0.05mm make sure that every parts can match well. |

Uniform Preform Quality: Advanced flow simulation software balances the runner system, guaranteeing consistent filling and wall thickness across all cavities.
Tight Tolerances: Precision machining (±0.005mm) ensures compliance with international standards (e.g., PCO 1881, BPF) for neck finishes and thread designs.
Durability: Molds are crafted from premium steel (H13, S136, or 420 stainless steel) with heat treatment (HRC 48–52) to withstand millions of cycles.
Conformal Cooling Channels: 3D-printed or machined cooling channels follow the contour of the preform, reducing cycle times by up to 30% and minimizing warpage.
Hot Runner Systems: Partnerships with top brands like Yudo or INCOE ensure leak-free, energy-efficient melt delivery. Valve-gated systems enable clean gate cuts for lightweight preforms.
High-Speed Compatibility: Molds are optimized for machines with clamping forces up to 1,500 tons, achieving cycle times as low as 8–12 seconds for 20g preforms.
In-House Testing: Every mold undergoes trial runs on injection molding machines to validate cycle times, cooling efficiency, and preform dimensions.
ISO Certification: Compliance with ISO 9001 standards ensures traceability and accountability at every production stage.
Third-Party Inspections: Collaborations with global certification bodies verify compliance with FDA, EU, and other regional regulations for food-grade PET.
Competitive Pricing: Direct manufacturing in China reduces overhead costs, offering savings of 20–40% compared to Western suppliers.
Long Mold Lifespan: Durable materials and coatings (e.g., nitriding, DLC) extend mold life to 3+ million shots, lowering cost-per-preform.
