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.

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.

Plastic Bottle Cap Moulds with the injection process

Manufacturing plastic bottle cap is quite a complicated procedure. This process generally welcomes the usages of latest machines that completely guarantee that products are designed and made in the best possible way. Albeit there are various other ways of creating different parts from a plastic, the injection moulding is mostly favoured.  

Making a plastic bottle cap moulds via injection process is quite a common method of creating different parts .It is the most essential component of creating plastic bottle stoppers. Various other parts like the automotives as well as wire spools too are manufactured through this procedure. Injection moulding is actually a procedure of creating different parts from a wide range of materials e.g. the thermosetting plastic as well as thermoplastic.

While manufacturing the cap of the bottle, the molten plastic is generally fed into the barrels that are quite heated up. After feeding they are further mixed and later compelled into the mould cavity. The next process is to gradually cool down the completed part and wait for it to amalgamate inside the metal mould that is either made out of aluminium or steel. Mould makers are responsible for making the moulds that are later precision-machined so that they can easily form various parts. 

The benefit of this process is that it tends to involve a very low labour price. In such method the rate of production is quite high and manufacturers can make use of several materials to make the parts.
