There are some points must be pay attention to:

·         The strength of the factory.  How many workshops and how many sets of import tooling machines from advanced country? for example: sodick precision EDM, sodick precision Wire cutting machines, fidia 5 axis milling center,  fidia 3 axis high speed CNC, Deep hole drilling machines and how big of the injection machine for mould testing?

·         The components of the department, do they have the R & D department?  How many design department and sales department?  Also tooling department, Quality control department and processing control department. 

·         Do know about the company’s culture, the management system and core philosophy, good company it will take their responsibility as one’s recognition, sensibility and belief toward oneself, others, family, society and the self-conscious attitude of related regulation abiding. For example, SINO MOULD Company’s core philosophy is Responsibility, every one work in SINO which has the top responsibility concept for our customer.

Sino Mould Co. Ltd - A Professional PET Mould Supplier in China

Pet perform mould is one kinds of the well sale mould in China, now more and more customer buy PET moulds from China, it led to a big growth of PET mould supplier. And we are one of the PET mould suppliers in China, but we not only offer our customer a PET perform mould, but a good PET molding solution.

With 20 years’ developing, now we are not a simple PET mould supplier, we have our own mould manufacture and injection molding machine manufacture, as well as our own hot runner brand. We have ability to help customer set a company for PET preform molding and bottle production.

As a professional PET mould supplier in China, all of our sales people have mastered a certain degree of technical, so do not worry about the communication problems, if you have any inquiry and questions, our sales engineers can reply you at first time.

Our sales engineer can offer you a solution for PET production line. Here we have simple example.

If a customer want to make PCO 28mm 37g preform, and he need to make 80000-90000 preform per day, then we can work out how many cavity he need for mould, and how big injection machine they need. If the customer work 20 hours in one day, 85000/20/60=70.8, it means he need to make at least 70. 8 pcs preform in one minute, and for 37g preform, the cycle time is around 20 seconds, it means we can make 3 shots in one minute, so 70.8/3=23.6. The result shows that the customer need to make 24 cavities for that 37.5 g preform. And for that PET mould, injection weight is important when we choose the injection machine, 37g x 24 =888g, because machine injection weight is according to PS material, so when we calculate PET weight, we need to multiply by 1.35 (PET density). So when we choose the injection machine, the injection capacity should be more than 1200g. And then, we choose auxiliary machines according to the injection and production capacity, such as, auto loader, dryer, chiller, crusher, mixer, cooling tower etc.

Above is an extremely simple example. If any customer has a big production capacity, he will need multi cavity PET mould and it will have multi option for production line. For example, if customer needs to make 96 cavities mould to reach his capacity, he also can choose 2 sets 48 cavity mould, and using 2 small machines.

About the design, we have a professional design team, we can offer you suggestion about the PET preform design, and make PET preform design according to the bottle. Besides we have ability to make bottle design, and make bottle design according to customers’ conception. We have different types of standard perform design for water bottle. Most PET mould supplier in China will not make complete mould design, but we will make all our mould design in details including hot runner system, every screw and even seal ring.

Usually, other PET mould supplier will not have service to go out for testing mould and machine, but Sino Mould Co. Ltd has a service team, their obligation is travel for help our customer set up whole equipment, of course, customer can send engineer or technical person here, we can training them.

Even our customer don’t know any technical about the PET production, just make us know the detail requirements, then we will work out the mould cavity, recommend the suitable injection machine model, and auxiliary equipment, and list out the option solution for choose. Lots of PET mould supplier just knows PET mould, but they don’t know which solution is better for customer, we have an absolute advantage on this point. So we are not only PET mould supplier, we are PET molding solution supplier.

SINOMOULD offers a qualified Plastic Molds Manufacturing Services in China

Plastic molds manufacturing usually including mold design, mold tooling, and mold testing.

Mold design is very important in molds manufacturing, because all following mold tooling will be strictly according to the mold design.

Usually plastic mold manufacture can make the product design for the customer; of course, they also can check the customers’ product design according to the molds manufacturing requirements. For some product, we could not make design the same as real sample, because we should consider shrinkage, deformation, and remolding after molding.

Injection Mold maker will make the mold design according suitable injection machine parameter. For example, Clamping force, ejector distance & force max. & min. mold size etc. Usually one mold has various options mold design, it mainly reflects in mold running system, ejection system, and mold structure. A professional mold maker not only offers you a workable mold, they will consider the production efficiency during the mold design and plastic molds manufacturing. For example, the will try to make the waste runner small to reduce waste material, they will make best cooling system to reduce the cycle time, in that way, customer can make more products in the same time.

In general, a good mold design should have reasonable runner system, optimized cooling system, simple structure, save and stable ejector system…Mold design embodies mold makers experience and specialization degree.

With a good mold design, we can start the mold tooling. Here are some common and major processing steps: CNC milling, wire cutting, EDM, boring, drilling, and surface treatment…But only with good tooling machine is not enough, experienced mold maker known what machine tooling way is best suitable for molds manufacturing. For example, some hole in mold, we can use wire cutting tooling, and also we can use drilling machine; for words on the mold surface, we can make it by chemical corrosion, as well as laser lettering; some small engraving can be replaced by EDM tooling and so on. Any way the accuracy of the tooling machine will directly affect the quality of the mold, so lots of precision tooling machine is used in mold finishing step.

Besides these tooling machines, inspection machine is very necessary, a good mold maker will control every tooling step in molds manufacturing, after precision tooling, we need to make inspection to check if the machine tooling is in place. After mold finished machine tooling, fitting is very important molds manufacturing procedure. Good tooling will make the mold size very close to the design, but the mold still need to fitting on the machine, it will make the product in good appearance, and make mold testing more smoothly.

After finished mold tooling and mold fitting, we will test the mold. We consider the testing as molds manufacturing because we hope to check the mold problem during the mold testing.

If we test the mold carefully, we could not find out all mold problems, and it may bring us risk in the future production. Customer will use different injection machine to run the mold, so we should make sure the mold can running in different condition. We can use high speed, high injection pressure to test plastic mold, most defects will appear out under that kind of testing; if we can find the mold problem in outside, it is easy for us to solve the problem.

In addition, before ship the mold to customer, SINO MOULD usually makes simulative operation for 2-4 hours according to different mold; it will make sure we can offer a qualified mold to our customer.

A professional mold maker will control molds manufacturing strictly, to make sure they can offering customer a good mold solution.
