Water Cap Mold

In drinking market, water cap mold anti-theft drawing will be more popular because it could give customers impression that water bottle was not been open before. So, this kind of water cap mold took a high proportion in factory cap mold exporting.

Anti-theft cap 

Anti-theft caps molding

1. Caps need good assembling with injected PET preforms, no matter its fitting issue or water seal function. Designer need to consider its suitable cap ribs thickness and demolding angle.

2. For injecting this cap mold, raw material with high MFI will be easy for injection and ejection, index around 20 will be prefer.

3. Anti-theft water cap mold had two kinds of drawings, one is anti-theft was designed by mold slides moving, the another way is not but customer need to purchase cutting machine, then cut injected caps into anti-theft ribs.

4. Slides cap mould drawings need to design with multi-group water lines. Cooling diameter dimension bigger than 10mm will be better in cooling result. Besides, air venting system is also pay more important role. Designers need to seriously consider its position and make a suitable solution plan. Normally, once drawings finished, our team will make mold flow analysis. This way could check injection balance or not, injection pressure and check suitable clamping force.

5. To make a high precision and high quality anti-theft caps moulds, tooling machines are important. High precision lathe, EDM and wire-cutting, all are most important process.

6. Once cap mould work with high speed molding machine, its cycle time will be greatly reduce to shortest. High speed and high injection parameter, caps molding will be quick and nice performance.

Keep every process perfect, this is key to achieve a good quality anti-theft cap moulds. If you are just now in China Huangyan Mold town, welcome to visit our factory to realize our quality control system and making process. Thank you for your time for reading.

PET preforms molding machine

To make an efficiency and stability running PET performs molding machine, this drives each water bottle preform machine suppliers to invent huge money and make development. 

As one of PET machine manufactures, we put our effort in water bottle line production from 1992. Injected preform molds, PET molding machines and so on, every machines were designed independent and be innovate.

Below listed how to chose a suitable PET machine in our factory.

1.Various machine tonnage choice from 250ton to 650ton. 
Accord to our sensitive market knowing, this region is very suit for current Injected preform molds production. Before considering machine tonnage, you need calculate your proforms injection weight at first. For example, standard PET preform information is 28mm neck, 21g, 72 cavities. Then we use multiplication and shrinkage, finally got machine injection weight. Next accord to mold structure, to calculate mold size and consider mold max./min. Thickness and clamping force. So finally, 650ton PET molding machine is optimal solution. 

2.PET special screw and barrel. 
As the property of PET raw material is high toughness, good material flow, and after heating, its temperature could reach 280-320, that’s we special improve screw and barrel to improve PET plasticization ability and optimal L/C rate consideration.

3.Famous brand spare parts on machine component. 
CPU use KEBA Austria, Inovance for servo drive, Phase for servo motor, Yuken for oil, Omron for switch and so on. With those, it could easy for after-sale maintenance. And except those goods brands component, PET machines also satisfy CE standard. Besides, we had already built many agents all over the world, such like, Spain, South Africa, Mexico, Russia, Morocco and so on. Quick spare parts sending and training service will be near your side.

Thank you for your time reading and welcome your suggestion.

PET Preform Mold

Multi-cavities PET perform mould is widely requirement in water bottle factory as it will greatly improve production capability. Besides, long mold life, nice appearance bottle perform, it is also as a standard of measuring qualified PET performs moulds.

Below lists characteristic of PET preforms mould:
1.    72 Multi-cavities, perform is 28mm neck, weight is 21g, cycle time is about 33s. Mold core and cavity use S136 and mold base is P20. Besides, it applies Yudo hot runner system.
2.    Short cycle time. Preform production capacity needs huge, so except multi-cavities, mold structure also needs simple and good cooling system. And our working team was rich experience designers, technical manages, workers at least 6 years which special on package Preform areas.
3.    Interchangeable inserts: If bottle perform weight are similar and could within control, then mold structure could design with interchangeable inserts which could save mold cost.
4.    Easy maintenance. Each cavity was standard dimension which was made by Japan Marzark prevision lathe. Take advantage of high precision tooling, it could interchangeable and easy maintenance.
