Plastic Injection Molding Machine - Blog
Theinjection moulding machine is consisted of injection device , clamping device ,hydraulic system , electric control equipment. As the important system ,hydraulic system play an important role in theinjection machine’s operation.
The hydraulic system and electric control equipment is the equipment for ensuring the processing technological requirement , including the temperature ,pressure ,running speed , cycle time and the work accuracy.
The main constitution of the hydraulic system:
Pump in Hydraulic system: The different size of hydraulic pump ensure the speed and the pressure of the Hydraulic working parts during the operation process.
Valve in Hydraulic system: There are various of hydraulic valves , including water relief valve、reversing valve、One-way valve、pressure regulating valve、back-pressure valve.
The main function of the hydraulic system:
It can change the speed of mould clamping , mould opening and control the movement of the injection base . What's more , hydraulic system can also control the process of the injection ,maintaining the pressure ,pre-plasticizing .

DKM is injection molding machine manufacturer China, is the newly born plastic injection molding machine factory, we supply high quality injection molding machine and offer fine injection molding technology online service.
PET injection molding machine is one of our best products, We design high quality PET perform injection moulds and PET injection molding machinery, also we supply Hot runner system to match with PET injection molding production line. As mentioned the PET injection molding production line, the PET perform moulds with hot runner is needed, and the PET injection molding machine play a important role in plasticization. The PET injection molding machine is on the base of standard injection molding machine equipping with enlarged and extended screw. According PET raw material physical property, we choose PET dedicated barrel and dehumidifier. For PET injection molding line, PET injection molding machine is not enough, it still needs some auxiliary machines, like:
Plastic injection molding machine specialized chiller
Plastic injection molding machine specialized dryer
Plastic injection molding machine –Auto loader
Plastic injection molding machine dehumidifier

Plastic injection molding process means under the given conditions,plastic parts can be made by
the injection machine and injection mould.The following are the plastic injection molding process' steps:
Mould clamping and locking in plastic injection molding process
Firstly , themould should be clamped under the condition of high speed and low pressure.When the female mould and male mould become closer , the speed will be lower .In order to lock the mould closely, the pressure will be higher and the speed will be lower.
2.Injection device move forward in plastic injection molding process
The nozzle and the mold runner entrance can be jointed with the pressure ,which can make a good preparation for the injection.
Injection and pressure maintaining in plastic injection molding process
The pressure which screw head act on the melt material called first pressure. The feeding effect by the pressure maintaining can avoid the melt material shrinkage ,it is the second pressure.
Cooling parts and preplastification in plastic injection molding process
In order to shorten the cycle time, the preplastification and the parts cooling can be done at the same time.while the parts cool down by the mould's cool effect , the screw's movement can finish the preplastification process.Usually,the preplastification time is less than cooling time.
The injection device's backward in plastic injection molding process
Whether the injection device back or not is depended on the plastic's process technology.The injection device's backward can avoid lower temperature of the plastic material in nozzle by the long-term contact of the nozzle and mould.
Mould opening and piecework ejector in plastic injection molding process
When the plastic parts cool down ,the mould should be opened , with the function of the ejection system ,the workpiece can be ejected .
Dakumar injection machinery company is a subsidiary company ofSINOGROUPE company .We are the famous injection machine manufacturer and innovator in china .If there are anything we cna do for you please contact me,MISS MAY.

Time, Pressure and Temperature in Injection Molding--Temperture
There are three factors which are important to the injection molding process. These three factors are time, pressure and temperature. In this passage, we talk about temperature in injection molding.
Temperature
Among all kinds of temperature, extruder barrel temperature, nozzle temperature andmould temperature are the most important three ones during injection molding process.
Extruder barrel temperature
During injection molding process, extruder barrel temperature, nozzle temperature and mould temperature should be controlled carefully. Among these three one, the former two is related to the plasticizing and flowability of plastic while the latter one is related to the flowability and cooling of plastic in injection molding process. Different plastic has different melting point and thermo-decomposed temperature, the injection molding temperature should be kept between them. Usually high temperature means relatively good flowability, which sometimes will lead to overflowing and flash while low temperature equals to relative bad flowablity, which will result in melt line,unfilled parts and ripple in injection molding process.
Nozzle temperature
Generally the nozzle temperature should be lower than the barrel temperature. If the nozzle temperature is too high in injection molding process, melting plastic will drool in nozzle and the plastic will decompose because of high temperature. And if the nozzle pressure is too low, cold material may block the nozzle or may be injected into cavities in injection molding process which will lead to unqualified products.
Mould temperature
Mold temperature is also very important because it can directly impact the flowability, the cooling speed and the performance of plastic products.

Robot for injection machine can imitate the part function of human upper limb, and it can be controlled automatically to deliver products as arranged.
When the arm of robot falls, the mould in the injection machine will open.
The injection machine ejects products and then sends an ejection signal to the robot.
The robot stretches into the cavity and grabs the products.
Then the robot sprays release agent to the cavity.
Then the robot rises and leaves the cavity.
The robot sends a mould closing signal and then makes theinjection machine closed.
Then the robot lays the products in the assigned position.
After everything has been well done, the robot will back to in situ and prepare for the next action.

Water cap molding line is a mass production line for cap mass production.We could offer you a high efficiency cap production line for different kinds of caps.
Water cap molding line include manufacturing workshop with high speedinjection molding machine,water cap mould,water chiller,autoloader,water supply,air supply and power supply.There also required a technical person for the machine operating.
For the cap with high quantity requirement,sometimes we will suggest use die casting molding instead of multi-cavity cap mould.Die casting molding could help to increase the mass production quantity.
There is huge consuming for the caps and bottles for soft drinkings,as most of the bottles and caps are disposable after the drinking finished.That's why there are large demand for the cap and bottle molding line.If we could reduce the molding cycle time 1s,we could increase the production efficiency 5%-20%.So a good injection molding machine and a well designed cap mould is very important for the cap molding line.
