Chinese mould give an impression to world that it is cheap but not high quality, it’s true that most mould factory do in this way, offer low price and not high quality mould, even bad. Frankly speaking, it is not good for the whole industry, and I believe most purchase want to get the mould which can help them to make money, not rubbish even cost money.

 

Chinese mould manufacturer

Sino Mould is one of the leading mould manufacturers in Huangyan China. Our mentality is to make win-win cooperation with customer; we don’t want to do one time business. Even our price is not as cheap as other small factories do, because we believe even we cannot do the mould as good as European country, but our mould must worth its price and can help customer to make profit. What we looking for is most cost performance mould to customer.

Sino Mould has most advanced tooling machine in Huangyan, we invest around 5Millon dollar to buy new and high precision tooling machine in 2010, so only some mould especially for high standard mould, only we can do it. What I want to say, maybe you pay 20% more at beginning to buy the mould from us, but we will bring to you is at least 50% more profit from our mould.

In mold labeling is no more a new technology, more and more factory familiar about this technology and knows some skill to make the mould, but how to do this kind mould perfect?

In mold labeling mainly apply with thin wall container production, and with robot system to put the label and pick the product out from the mould, so when do the design, we must consider the robot system, if with multi cavities; we must know the center distance of the robot. It is about the design part.
Besides the design of the mould, mould tooling is another main factor need to be considered, thin wall container mould need to ensure the mould precision, because the product wall thickness is only about 0.5-.0.6mm, so small difference will have big result on product.
In mold labeling also requires for high speed injection molding machine, high speed injection machine is to meet the demands of output, and high speed injection machine can control the injection more precision, the machine is more stable.
Sino Holdings Group is one of the first factory who offer IML production line, now it is very mature in our company, we can offer the turnkey production line, including the mould, machine and robot system.
If you are interested in IML production, come to Sino.

China has so many plastic molds manufacturer, mostly in Zhejiang, Jiangsu, Guangdong province. Now that China's mold manufacturing industry has developed into technology-based, so many customers are willing to buy the mold in China. Of course, buying plastic molds in China has many advantages.

1 China's mold have favorable price. But I do not recommend customers to choose suppliers by price, because low price is certainly unable to build a good mold, it is better to choose a reputable mold company.

2 plastic moulds in China have short delivery time. Customers who buy the mold from Americas or Europe know that their mould price is very high, and delivery time is long. A company developed a new product, if it could not go on sale as soon as possible, then your competitors will get the market instead of you.

3 Many of China mold maker can help customers make production, if not, find injection molding service in China is very easy, and the price is low.

4 Finally, I must mention that the quality of plastic molds in China, Chinese mold manufacturers now is focusing on quality and technology, they spend money on high-precision processing equipment, inspection equipment; They use good steel, hot runner system and spare parts to processing mold, the mold quality is not worse than in Europe.

preform mould

 Preform mould is very important for the production of water bottle, only qualified preform can be blew into a good bottle. The prefrom has an international standard size, so the preform mould maker also have their own mould standard.

Generally, preform moulds are multi-cavity, the number of cavities can be made in 2,4,6,8,12,16,24,32,48,72,96.... The more number of cavity preform mold is more difficult, because the multi-cavity hot runner arrangement, uniform flow control is more difficulty. Preform mold structure is simple, but high precision, each cavity of PET mould has the same design, so they are interchangeable.

Because preform injection volume is big, so all of the preform mould use hot runner valve gate, and the preform is no tail. Due to the large output, PET preform mold cooling is very important, preform basically using fountains cooling, and production must use chillers. Some customers will use mechanical robot cool PET preform outside the mold in order to increase production.

It have to mention here that, dehumidify PET plastics and mould are very important. PET material have strong hygroscopicity; and mold as internal cooling, the moisture in the air will aggregate on the mold surface.

For more preform mould information, please feel free to contact us.
