| PET preform Mould Feature |
| 1. Mould plates are P20 steel with pre-hardening process. Core, cavity and neck screw are made of S136 high Strength, anti-corrosive stainless steel. Mould plate is completed by one-time processing to ensure the concentricity of moulding hole and guide bush, guaranteeing the compact structure of mould. |
| 2. Spiral cooling design for each single core and cavity, it helps to lessen the cycle time, improving production efficiency and savign costs. Opening/closing pulling plate adopts bearing slide type to drop the preform with realiable structure.And it is a highly integrated process of slider, pushing plate and ejection. All sliding parts surface inlaid self-lubricating copper alloys to ensure low friction effecient and strong wear-resistant. |
| 3. Self- lock individually for each cavity to guarantee high precision and less defect of the |
| final preform production and also convenient disassembly. |
| 4. Off-center adjustment system to ensure preform thickness difference < 0.10mm. |
| Adopting double cone positioning principle guarantees high manufacturing precision to ensure the product without appearing flash, different size, irregular and other defects. |
| 5. Experienced designers design preform mould with the help of computer according to the final bottle shape; Preform thickness and height is reasonably and perfectly designed to ensure the final bottles weight light but feel hard. |
| 6. Hot runner valve gate is available; No need to cut preform tail and it would save labor costs. Standard inter-changeable mould components for easier replacement. |
| 7. Hot runner system: China advanced brand or imported hot runner system brand such as Yudo/Mastip/Hasco etc. |
| Each cavity has independent temperature control and heater system. |
| It will prevent the white defects on the preform and improve the qualtiy of plastic products. Advanced hot runner system assures lower level of AA value. |
