Plastic Injection Moulding Solution

G as assisted molding has widely used in plastic injection molding line, compared with traditional injection molding, gas assisting injection molding have many advantages. 1.  S maller of delete sink mark, 2.  L ower injection pressure makes product internal stress smaller, 3.  S maller internal stress and bucking develops product size stability, 4.  W ill save up to 50% raw material, 5.  S hort cooling time leads production  cycle time shorter, 6.  A dopt short inject technology will make lower injection pressure and reduce the clamping  force. S tandard air injection pressure is 7-25 MPa. Gas-assist molding technology procedure: F irst stage: Polymer Filling P olymer filling, form frozen layer in mold wall. S econd stage: Gas injection Nitrogen was injected  into polymer melt, push it go ahead to fill the cavity. T hird stage: End of has injection T ill filling the whole cavity and form gas channel ...

In Huangyan mould town, you will find more than 100 factories to make trash can moulds. But less of the company can make 120L industry trash can production line  injection molds, or 240L, 360L, 660L dustbin mold.

Sino mould is a top quality p reform mould manufacturing  company in china we provide customers high quality moulds with the most reasonable price. We provide customer very well service including before the sales our professional workers can give you the professional ideas about the moulds,during the sales we can precision the design and making by the top machine and after the sales we have 12 months warranty time. Here i want to introduce you the preform moulds. PET has the features of the weight is light, transparency is high, Impact resis tance is not easy to fracture , also it can pre vent carbon dioxide gas, keeping soda has "steam". And those are the reasons why PET plastic widely used for packaging, especially carrying water and soft drinks. Normal PET bottle production process is let the PET additive oil after hot melt injection it can becoming preform, stored in a certain temperature humidity environment after a period of time it can become two conditions...

Do you have met disposable plastic cuvette production equipment such as off center, low precision, low qualified product, low acceptance rate phenomenon? They are always headache problems to our market. And how to realize test tube mold high precision injection, high speed production with high final product rate etc problems are the key of the research and development for our industries. Currently, due to the technical bottle neck, all of the China mainland test tube, syringe and other huge output capacity production import the equipment from oversea countries. The manufacturers have to adopt European or Turkey countries injection molds, Japan, Germany, Austria made injection machine to realize large output quantity requirement. Because the machines and molds couldn’t achieve these demand made in China. On the other hand, if we choose Engel, Toshiba, Arburg brand machines for new companies, investor will face huge amount of money problem. Zhejiang Dakumar Machinery Company be...

After 3 years research and development, Sino Mould make 32 cavity PET test tube injection mold successfully. Sino is the first company who can make such a multi cavity test tube mold in China. SINO shown the mold production in Chinaplas 2017, which has attracted many customers eyeballs. In general, Test tube ’ s precision is very important. So we must use high precision process machines to process the cavity and core parts. As is known to all, the test tube is very long, and the diameter is always small. So we must make sure the core and cavity is 100% straight. It is the most difficulty tecnical point in making PET test tube injection mold. Mould information: 32 cavity PET test tube Cycle time: 12 seconds Cavity: 32 Injection gate: 32 tips Anole valve gate Injection machine information: DKM-200HH PET injection molding machine High speed series PET special injection molding machine Advantage of PET test tube production line: High transmittance surface with...

Since the early 90s of last century, Europe, Japan, America, etc. developed countries eliminated three-plate injection machines, which models up to 800T. But adopt two plate injection machine or direct press machine structure. Why? Now I listed the difference between two plate machine and three plate machine: 1.        Three plate injection molding machine’s clamping force was controlled and estimated by human eyes. But two plate machine was controlled by computer, it realized digital setting, screen display and storage function. Which means three plate machine clamping force not as good as two plate machine. In addition: imprecise clamping force will cause the 4 problems: a.        Affect mold air venting b.        Increase energy cost c.        Damage mold d.        Need bigger injection pressure 2.   ...

Plastic dustbin always has 2 series: Industry trash bin and home appliance dustbin. Generally, industry trash bin material is HDPE, home use dustbin material is PP. plastic dustbin mold analysis is very important before mold production. Small dustbin injection will choose pin point gate hot runner system, large plastic trash will choose one tip or multi tips direct hot runner system. In order to reduce the cost of mold, we will make the cavity steel with 2 parts. The reasons are to make process convenient and save steel material. In addition, the CNC knife longer size is 50cm. Some customer will make special texture on the product surface, most of them will choose mirror polish. And some will choose beautiful texture, if you have the texture code, please tell the supplier in advance. Different texture will charge different cost. In order to longer plastic trash bin mold life, we suggest customer choose mold with DIN1.2738 steel to make the core, cavity and stripper. Because i...

Milk is one of the oldest natural drinks all over the world. It was proud of “white blood”. So the milk market is very big in all ages. Plastic milk crate is very useful in transport and storage. To start a high production milk crate production is a very good chance not only to milk manufacturers,but also plastic products makers. Recent monthly, there are some milk manufacturers contact with me to make custom milk crate production line in his new factory. She said,” the milk crate is too much expensive in the market, we need many crates every year. So we would like to make the crates by ourselves.” This customer has milk with different packages and different sizes. She want to package the milk separately, so we will custom a divider based on the milk sizes. You can tell me all of your opinions and ideas, for example, high speed production, strong enough, folding, need divider, with 4 arms, use recycle plastic material, etc. different require will have different structure ...
