Molds are coated with anti‑rust oil, wrapped in plastic film, and packed into sturdy fumigation‑free wooden crates. A digital copy of mold drawings and a test video (USB or QR code) are included inside the crate.
Standard molds (e.g., 16‑32 cavity preform or cap molds) typically take 4‑6 weeks. Complex or high‑cavity molds (48+ cavities) take 6‑8 weeks, depending on complexity and current order schedule.
Yes. We offer a total solution by designing the cap and neck finish simultaneously to ensure perfect fit and 100% leak‑proof sealing. Virtual assembly tests and physical prototypes are conducted before steel is cut.
Yes, we mainly do custom molds. You can provide drawings or samples, or we can design from your concept. Our engineering team performs DFM and mold flow analysis to optimize the mold structure.
We are an integrated manufacturer with our own mold factory and international sales department. All molds are designed, machined, assembled, and tested in‑house – no middlemen.
Please provide: 1) 2D/3D drawing or physical sample; 2) Material type (PP, PE, PET, etc.); 3) Cavity requirement (e.g., 16‑cavity, 32‑cavity); 4) Estimated annual production volume. We will then recommend the right steel grade and provide a detailed quote.
During working days, we will reply within 12 hours after receiving your inquiry. For urgent requests, please call or contact us via WhatsApp.
