High speed injection molding machine for production of plastic material
Use of plastic is increased day by day but no one known the manufacturing process behind that we are giving clear idea about what are the process requires for production of plastics. Injection molding machine is used for production of plastic material. Injection molding machines are used for preparing small material to large material like entire car body. There are two major parts in injection molding machine one is injection unit another one is clamping unit. The function of injection unit is to convert polymer resin to molten stage and fed to the mold. The injection molding machine is differentiated with respective of their driving system like Hydraulic, electric and Hybrid systems. Injection molding requires six steps to prepare plastics. First step is clamping is to fill the raw material to the machine with some pressure. Second step is injection here the raw material are passed to the injection barrel and the raw material are heated above their melting point to make raw material to liquid stage and passes to mold like screw and ramming device. Third step is dwelling in this step the pressure is applied in mold to avoid the cavities in the molted material. Fourth step of the process is to cool the mold for some time followed by re opening the molds and ejecting the product from the Injection mold.
Injection molding machine china. HAIFLY is one of the Chinese companies who manufacture injection molding machine for less amount with two years warranty. They are not only manufacture injection molding machine for plastics and also for PVC, servo injection molding. So the plastic manufacturing industries around the world are likely to purchase injection molding machine china from china.
Due to large use of plastics, the manufacturers have to use advance technology to improve the production. For those purposes the high speed injection molding machine is developed. This machines also follows same six steps to produce plastics but some alterations are made in the parts of the injection molding machine. Some of the changes are use advanced toggle mold for clamping unit, In Hydraulic unit the pressure flow adjustment are fitted to improve the efficiency, In injection unit double cylinder arrangement are used to improve the performance of the injection unit, control unit place a vital role for manufacture any product because if the pressure are not maintain in hydraulic unit it will create cavities in the material so control unit are also designed based on the changes made in the injection molding machine.
Increase in requirement of plastics, the high speed injection molding machine play the vital rule in plastic manufacturing industries. The advantages give the clear idea about the product. The main advantage of this machine is that it produces the large quantity of products with higher quality.

The Basic Facts Of Plastic Injection Molding Process
Plastic injection molding process by definition may be the progression of injecting plastic-type right into a mold (or mould in European circles), cooling the plastic-type, ejecting it in the mold, and packing the completed item for sale on the consumer. This sounds easy and in it's fundamental form it is, however the procedure required with generating all this take place is in fact very complex.
A range of components are produced using plastic injection molding process which varies in the smallest component to an whole body component of a vehicle.Plastic-type components applied for the plastic injection molding process are thermoplastics or thermosetting plastics. Each the thermoplastic and thermosetting plastic molding are polymers. Some broadly utilised thermoplastics are nylon, polyethylene, and polystyrene while bakelite, vulcanized rubber are the extensively utilized thermosetting plastic. At times a polymer with a quite excessive elasticity is also utilised. This type of polymer is known as elastomer
The Basic Steps of Plastic Injection Molding Process can be Described in Six Steps. These include Heating, Plasticizing, Injecting, Packing , Cooling, and Ejecting are:
- Heating the plastic material resin for the required variety of the item getting used.
- Developing the shot size by way of use of a reciprocating screw which conveys the melted plastic-type for the front in the screw.
- Injecting the plastic-type to the mold beneath stress to fill the cavity of the mold.
- Packing the plastic-type to produce a total portion within the mold.
- Cooling the plastic in the mold by means of the usage of cooling channels most commonly with water.
- Ejecting the cooled component in the mold.
- Repeating the process more than and more than once more.
Troubleshooting on Plastic Injection Molding Process and How to Improve
- FlashingFlashing is the excess material at the ends of the part or on the side of the parting lineFlashing on plastic injection molding process caused by the injection speed is too high or excessive volume of material so that material into the gap cavity, clamping force or power the press mold is less so material into the gap parting line, or mold condition defects.Improve: decrease injection speed, review the position of a stroke and a holding position, raise the pressure mold clamping, check whether the mold is a problem.
- Silver-StrikeSilver-Strike is sign white / silver which appears in the direction of material flow injectionSilver-Strike on plastic injection molding process caused by resin material moisture is still high, the moisture content is transformed into a gas that is mixed with molten materials within the cylinderImprove: needed a good drying material with time and temperature sufficient to remove moisture.
- WrapWrap is product form bent / curvedWrap on plastic injection molding process caused by common lack of pressure distribution of the product or differences in depreciation.Improve: increase cooling time or decrease injection pressure, check for mold cooling system or correct the mold.
- Bubble-BlowholeBubble-Blowhole is hollow or air bubbles that occur in the product, but we can not see it unless the product is transparent or air bubbles that occur on the surface of the product.Bubble-Blowhole on plastic injection molding process caused by the gas mixed with molten materials within the cylinder.Improve: make sure materials have passed the drying process properly, raise the screw back pressure during the plasticizing process to force the gas out of the cylinder, improving gas ventilation systems in the mold so the gas is not trapped in the product, decrease injection speed to give time for the gas out through the ventilation systems.
- WhiteningWhitening is white marks / cracks / under cut on the product side of the tangent.Whitening on plastic injection molding process caused by the different pressure of the inequality area of a product, mold design that makes uneven cooling products between one side with the other side, or the product over pack in some places as the material coolsImprove: polish on the mold cavity is happening whitening product, lower injection pressure to prevent over-pack in the product
- BurnmarkBurnmark is scorch mark on a product in the last section filled with material.Burnmark on plastic injection molding process caused by the burning gas because the gas trapped, injection speed is too high, or a gas ventilation system in the mold is blockedImprove: add scerw back pressure to reduce the gas content in liquid material, lower injection velocity and widen or create a gas ventilation system
- Short shootShort shoot is some of the product is lost or not filled materials during the process of injectionShort shoot on plastic injection molding process caused by the injection speed is too low so that the material to harden before they reach the last section filled with material, mold temperature is too low so blocking the flow of material, the volume of material is less or unstable.Improve: increase injection speed and mold temperature, check the check-ring is worn or is normal to prevent backflow material from the front to the back, review the position of a stroke and a holding position.
- Sink-markSink-mark is concave or hole on the surface of a productSink-mark on plastic injection molding process caused by the differences in viscosity between the material with normal temperature and materials that require a longer cooling time and gathered in one side.Improve: in principle, very difficult to find solutions to this mold design, add a holding pressure or holding pressure time to maintain stable material pressure within the mold, extend the cooling time to reduce the depreciation rate, change the form of mold to reduce the level of viscosity differences (for example, by adding dummy-pin.)
- Flow MarkFlow Mark is signs or wave lines on the surface of product.Flow Mark on plastic injection molding process caused by too low injection speed, mold temperature is too low, or mold gate hole is blocked so that the material can not flow normally.Improve, increase injection speed, mold temperature and check for mold gate holes
- Jetting lineJetting line is line burst on the surface of the product, starting from the gate pointJetting line on plastic injection molding process caused by the mold temperature is too low and the injection speed is too high that will occur in bursts mark on the surface of the product Improve: raise the mold temperature and injection speed down.
