SINOPK has rich experience on plastic preform mould designing & tooling

In our daily life, plastic drinking bottles are wildly used, and we can see plastic drinking bottles everywhere, such as mineral water bottles, Coca Cola bottles, fruit drinking bottles, 5 gallon water bottles, even Cosmetic plastic bottles… All of these bottles are made by plastic preforms, and all plastic preforms come out from plastic preform mould.

Sino Package Mould Co. Ltd is professional in manufacturing plastic preform mould. We have made plastic preform mould from 2-cavity to 120-cavity. We are famous plastic preform mould supplier in China, located in HuangYan – plastic mould town.

We can make PP plastic preform mould, professional PET preform mould and PC preform mould for you. Normally, PP plastic bottles are for baby drinking bottle use, PET bottles are applied the most widely; PC bottles are with big thickness and for reusable drinking bottles.

For plastic preform mould, the valve gate is better, comparing with hot runner or cold runner gate. In our company, if our customers have no special requirements on hot runner brand such as Husky, Yudo, Incoe, Mastip, etc. we suggest to apply our Sino Holdings Group own hot runner brand – Anole, with German heating elements and can supply you with a long guarantee and a good after-sales-service, and of course a competitive price.

You may ask the difference between different size bottles and the weight. Normally, 28g+/-2g preforms can blow 0.5L bottles, 40g+/-2g preforms can blow 1.5L bottles, and 88g +/- 2g preforms can blow 5L bottles.

Because PET and PC plastic material are very hydrophilic, if material is wet, the preforms will be not transparent and become white. So before production, we must dry PET and PC completely. For PET material, the drying temperature should be between 140° and 160° for 4 hours; for PE and PP material, the drying temperature should be around 80° for 2 hours. If during injection, the temperature is too high, the preforms will become yellow or even become black, it is not good for plastic bottles or using or selling.
