1. Self- lock individually for each cavity to guarantee high precision and less defect of the final preform production.
2.Off-center adjustment system to ensure preform thickness difference < 0.05mm.
3.we design preform mould according to the final bottle shape; preform thickness and height is reasonably and perfectly designed to ensure the final bottles weigh light but feel hard.
4. Hot runner valve gate is used; no need to cut preform tail and low defect rate
5. One temperature zone controls one point temperature; it would prevent the white defects on the preform.
