And because of this, some powerful plastic bottle manufactures prefer to purchase bottle preform for processing. And it should be remembered that most professional manufacturers adopted this processing method.        

The production of preform should following the standardized process, and it can be differentiated by size, gram weight and raw material. Preform can be transparent or opaque, with different colors.

 That is to say, great efforts should be made to improve the quality for preform. Only high quality preform can help create a qualified plastic bottle.

What’s the Challenge of Preform Mould Industry?

The basic requirement of preform mould products are made free from any defect or flaw. There is no doubt that “quality first” is a fundamental principle that guide the much aspect of preform mould’s production. Even though the products we see around us are made of plastics, they are could still be strong and long-lasting.

Second important is the uniqueness of preform mould products. Generally speaking, each manufacturing project has its own shapes and sizes. With the help of preform mold technology, this plastic has been shaped in a most suitable treatment.

For buyers, whether it could delivery products on time is also an important judgment on factory selection. No matter how perfect your product is, you have to face a lot of trouble if you are failure to ship the goods in time.

Choose the Right Preform Mould Maker

It won’t be easy to find an appropriate preform mould maker in an unfamiliar place.

Firstly, you should have a good knowledge of the characteristics of raw materials and technologies in preform mould industry.

Then you should have a clear idea of the preform mould makers, and choose the most suitable one based on current understanding.

Last but not least, for you-the user, or maybe a distributor, the design ideal shall be stick to, and figure out which one is the best to carry out your ingenious construction.

Challenges To Preform Mould Maker

How to design a best quality product within a budget limitation is a big problem for today’s perform mould maker.    

 As we all see, most Mineral Water Brands require a specific design and color to consistent with their public image. Yes, the custom design has become popular in today’s production activities.

When it considered the customization demand, the material is also different. Some materials are more expensive for its superiority in some aspect. Meanwhile, high quality machine is the basis to produce perfect products.        

Whether the high quality products or the machine, the ultimate goal is to make the customers have a good impression on their products, that they could survive and development in the intense market competitiveness.

The technical specifications of preform mould.

1.     Main components: the materials of cores and cavities are imported Germany 2316,the heating hardness can reach HRC46±2°. The thread is made of imported material S136 stavax(ASSAB from Sweden), its processing accuracy can reach ±0.02mm(depend on the perform). The interchangeability of the mould components is very good, and the polished surfaces reach the second class mirror side degree of finish.

2.     Mould frame: mould plate is processed by the Japanese processing center. Plate A and B adopt the material of P20, their hardness is HRC30-32; the material of hot runner, pull plates and push plates are H13. Other mould plates adopt 50# steel.

3.     The heating element of hot runner is GERMANY HOTSET. Nozzle is made of berylium copper imported from Japan.(Copper alloy + H13).

4.     Pin valve control system: the valve needles are imported from Japan.

5.     Opening and clamping system: use the lubricating graphite copper sheathing. In order to decrease fret, to guarantee the accuracy of mould and to improve the life of mould, we adopt the lubricating graphite copper plate between plates and pull plates.
