Multi-cavity PET Preform Mould with High Accuracy

Sino Mould makes high standard mineral water PET preform moulds for partners, which own good performance with longer mould life, meeting the requirement of mass production. There are kinds materials of Injection perform: PET、PVC、PP、PAN, regarding PET preform (strength of extension is more 5-10 times than PE), for further processing, is usually used to be blowed to bottles with different shape (like round, square, or others), and those bottles may be for packaging liquid, such as sodas, inebriant (beer, wine), juice, water, oil, condiment, medicines, cosmetic, etc.   

Now, some points are listed for PET preformmould compared with other moulds:

1.        The steel of mould core and cavity.

As PET’s characters, mould steel should meet enough heat transfer efficiency and thermal conductivity. We usually use steel S136 for core and cavity of mould if customers have no other special requirements for steel.

2.       High standard for mould making.

This requires automation tooling equipment with high precision and measurement equipment, which could ensure that the precision of mould, when making the PET preform, it will be smoothly and no flaws.

Regarding this, I have to say that we owns pretty top equipment in China, when you visit SINO, you will find it valuable for PET preform mould maker to have rich experience and R&D capacity. That’s why we could make large multi-cavity preform mould (72-cavity one).

3.       The mould structure

For PET preform mould, the structures could be depend on the injection gate: direct gate, point gate, valve gate. And valve gate is suggested for partners, as much advantages here, like, shorten cycle time and save material in same condition, and when it blowing to be bottles, the bottom will be smoother, and improve the percent of pass.

There are others need to pay as well, for example, the interchangeability of weight of PET preform, material changing or special material, and so on. Each detail should not be ignored! SINO’s engineers are engaged in improving quality of plastic mould for PET preform now and in future. Hence, it also increases competitiveness of you and SINO for the long running.

DKM FACTORY FOR INJECTION MACHINE 

When people are looking for injection machine, the first is model, which should match their moulds, and base on this, they must pursue particularly good value for money of machine, so that their production line will be more efficient. And exactly to satisfy our partners, DKM apply top-class components in machine, like computer is KEBA, kinds of switch is OMRON, and breaker is Schneider, etc.

Custom injection molding machine can be offered for your product, for example, as the injection machine for making household appliance, like, refrigerator inner cabinet liner. The basic info is about container’s size, weight, plastic material, and special structure, which will affect the design of machine:

Size and weight → model of injection: injection weight, clamping tonnage, tie-bar distance, etc.

Plastic → screw of machine, such as, if the material is PC for container, then we should use special screw for it, as PC owns poor flow characteristics and takes in moisture easier, then the molding will be easier than normal screw.

Special structure → special action of mould → component of machine, like, if need to add additional air valve, lateral sliding.

Thus you will find that the injection molding machine is standard machinery but also customized, and most important of them will be the service. DKM offers a turnkey solution for your project development which include free machine analysis & design + production run + assembly + custom packing + shipping+ training and all others according to client's request.
