There are three important systems in injection mold, they are injection system, cooling system and ejection system, in which the cooling system is a most significant step, because the cooling good or bad will affect the quality of the products, the cooling time will affect the mould production, and also affecting production efficiency. So mould manufacturers will optimize injection mould cooling system design.

Injection mould cooling system design generally considers the following factors,

1. Mould waterway design should be independent, core and cavity are symmetrical respectively, if you want to fully cooled, separate some water groups, and use with water manifold collection.

2. The cooling water against the product walls should be uniform, and pay attention to the distance between the product wall and the water channel.

3. Cooling water inlet and outlet must be put at the bottom of the mold or at the non-operation side.

4. The most important thing is to ensure that the cooling water in the channel is turbulent. If the cooling water go through straightly, it cannot take the heat of the steel material, so if the water channel is long and straight, it is better to use a spiral baffle to increase turbulent index.

China is a biggest plastic products exporting country, lots customer buy plastic products from China every year. Of course , there are many ways to buy plastic products, we can directly buy the plastic goods based on supplied catalog, and we can also provide product sample or design to customized the plastic products.

Buy plastic products according to catalog is very simple, customers can choose their own style and quantity according to the market needs, these products are generally have short delivery time, because the supplier have ready equipment, some suppliers or even be in stock .

For custom-made plastic products, delivery should be longer comparing with above, because the supplier must make molds first before mass production. Simple products , mold design and production time can be 35-40 days, some complex molds or products require more time to built the plastic mould or assemble the parts together .

In order to reduce unnecessary trouble, many customers will choose to make the mold and produce products in the same company, they can done from product design to production, and product processing together, both to facilitate communication, but also to avoid shirk responsibility problems.

Injection molding is an important technology in plastic products making area.
How does it works? Do you know?

1.Injection molding step:

Melting the material by the screw high speed turning, and the speed is very important for melt , it is too slow, then the PET material will not be melt properly ,if too fast, then the PET material will be burns. Of course the barrel is important for heating.

2.Injection step:

it means injection the melting material to the mould .it need the injection molding machine provide the injection pressure for help the material full in the mould.

Then will need some time for keep pressure for molding.

After that, cooling the mould.The injection gate on the mold will be closed.At last, cooling the mould by air and oil.

Got the perform moldings: this is the last step .some customer need the robot for pick up the mold, some are let the perform molding drop automatically.

Sino Mould, professional injection mould supplier, have many years experience in making plastic injection mould.

If you have any further information, please feel free to contact us. We will provide you best service for injection molding.

And the best advantage is we use special material to make this kind of foldable crate. Foldable Crate also uses HDPE or PP for molding. But considering its durability, we choose a better performance material, which MFI is around 3.6~4.5g/10min, and its tensile strength is more than 25Mpa, tensile strength at break should be bigger than 60%, and shrinkage strength should be bigger than 40Mpa. In this way, we can make sure  Foldable Crate with good durability and long service life.

Plastic moulds design, manufacturing and plastics processing are closely related. The success of plastics processing depends largely on plastic moulds design effects and plastic moulds manufacturing, while plastic products is correct or not is based on the plastic moulds design.
Structural elements of plastic moulds design to be considered are as below:
1. Parting plane, is cooperating contact surfaces between mold core and cavity. Its location and form of the selected shape and appearance of the affected products, wall thickness, molding method, after processing, mold types and structures, methods and molding machine structure and other factors.
2. Gate system, the feeding channel from the injection molding machine nozzle to the cavity, including sprue, runner, gate and cold slug. Especially selected gate location should be conducive to the cavity filled with molten plastic flows in good condition, solid runner and gate attached to products on the cold material at the top of the mould is easy to be removed from the mould and (heat except channel mode).
3. Plastic shrinkage and the various factors affect the dimensional accuracy of products, such as mould manufacturing and assembly errors, mold wear. In addition, when designing plastic moulds, you should also consider the matching process and the structural parameters of the injection molding machine. In the plastic mold design has been widely used computer-aided design technology.

Anyone who want plastic moulds design service, or want to find a professional plastic moulds designers, pls kindly contact us.

Hot runner molds have an extremely wide range of applications in the following areas:
(1) Plastic Material Type
Hot runner mold has been successfully used in the manufacturing of various plastic materials. Any plastic raw material can be injected by cold runner molds which can use hot runner molds.
(2) The size and weight of the part
Hot runner molding parts, the minimum weight is 0.1 grams or less, and the maximum is 30 kg. The hot runner molds application is very broad and flexible.
(3) Plastic injection molding industry
Hot runner molds have been widely used in the electronics, automotive, medicine, daily necessities, toys, packaging, construction, office equipment and other industrial fields… Compared to ordinary runners molds, high injection efficiency, good quality molded plastic parts and raw materials savings, along with the development of hot runner molds technology and the polymer industry, the hot runner molds application has become increasingly widespread. Runner by heating method makes sure that the plasticizing raw material keeps in molten state in the runner and gate. Hot runner molds can make the material from the injection machine nozzle to mold inside are high temperature trough the heating main hot runner nozzle and manifold, and maintain the molten plastics until the material are injected inside the molds.

    Polishing is essentially the removal of metal by the action of free abrasive grains carried to the work piece by a tool.Here is several reasons for plastic mold polishing are liseted below:

1)Plastic mold polishing may achieve special optical properties in a product,will enlight beams pass through the produt wall(compact disc,mirrors,etc),any major unevenness or waviness will distort the light and result in poor performance of the product.
 
 2)Plastic mold polishing may enhance the appearance of the product,This is the most common requirement in plastic mold.It should be noted,however,that th appearance often is required for the visible outside only.Often,no polish is required on the seen inside of the product,and the finish there need not be better than that required for easy ejection of the product from the mold.For clear plastic products where the inside finish as the outside of the product.
 
 3)Plastic mold polishing may faciliate ejection.This applies generally produced by deep recesses in the cavity or where there is little draft angle specified,the cavity must also be free of roughness that may prevent easy ejection. 
We are professional mould manufacturer, if you have any mould enquiry ,please feel free to contact me!
