There are three factors which are important to theinjection molding process. These three factors are time, pressure and temperature. In this passage, we talk about time in injection molding process.
The time needed for one injection cycle is cycle time. The cycle time includes clamping time, injection time, holding time, cooling time in mould and other time.
1. Clamping time
Clamping time refers to the time for clamping mold in injection molding process. If the clamping time is too in injection molding, the mold temperature will be too low while molten plastic will stay in nozzle for too long time. If the clamping time is too short in injection molding, the mold temperature will be too high.
2. injection time
Injection time means the time from when injection molding process begins to the time when melt plastic filling the cavity.
In injection molding manufacturing, small plastic products only take about 3~5 seconds and large ones take about tens of seconds. The injection time has an inverse relationship with injection speed in injection molding process. Shorter injection time means faster injection speed.
3. holding time
Holding time refers to the time for continuing pressure on the plastic product ranging from 20 to 25 seconds or even 5~10 munities. If the holding time is too short in injection molding, plastic product will not be tight enough and cause dent and unstable size. But if the holding time is too long, the stress of product will be increased. It also will be more difficult to demoulded.
4. cooling time in mould
Cooling time means the time from the finish of holding pressure to the time when mould is opened in injection molding process. Cooling time depends on the thickness of the product, thermal property of plastic and crystallization characteristics of plastic as well as mould temperature. The criterion of setting cooling time is to make sure it will not lead to distortion of products.
In injection molding process, many factors can influence the products. Temperature is just one of them. If you want to know more, please contact us (Dakuamr MAchinery Co., Ltd).

1. Inspect the injection machine lubricating oil before operation. If possible,
3, Inspect the electric switches per shift, especially the safety door and limit switch.
4, Check the sound of machine. If there is abnormal sound, you should pay attention to them.
You can check the book to know some information,
But if you can not find the correct solution, Please contact us.

Dakumar Machinery is a leading plastictwo component injection machinemanufacturer in China. We can offer you high quality two shot injection machine, double color injection machine, bi-shot plastic injection machine China.
We can offer you both clear two components and mixed two component injection machines. For clear two component machine, we can offer two types.
The first type is traditional double color injection machine. There are two parallel screw and barrel. The machine platen will rotate for 180°after 1st injection molding. The second type is L angel double Two Component Injection Machine. This kind of dual color injection machine consists of one main common injection machine and an additional injection unit at side. The mould will rotate for rotate for 180°after 1st injection molding. Both of these two types of two components are suitable to injection molding for two colors or two materials. But the second type injection machine is more flexible and less expensive.
The L angel double Two Component Injection Machine can be used both as common one component injection machine and two component machine. This is new injection machine developed by Dakumar Machinery. If you have any interest, please feel free to contact me.

Purchase PET molding machine China
buy good quality perform making machine from China, perform molding machine Chinasupplier offers top quality perform molding machine. PET machine distributor support you with injection molding technology, PET perform molding technology and blowing solution.
For the PET perform mould, generally is multi cavity, so it requires thePETmolding machineshould have bigger injection weight than normal molding machines. When purchase PET molding machine the first factor to take into consideration is the injection weight, and then the mould can be fit on the PET molding machine and take out easily.
Purchase PET molding machine from Dakumar Machinery Co., Ltd, we have the machine from 118T to 650T. The injection weight from 188 gramm to 3993 gramm.
If you feel interested and looking for PET molding machine China, please feel free to send me email at promotion@dakumar.com

Servo motor energy saving injection molding machine is much popular than normal standard injection moulding machine. Servo motor machine equipped with high performance servo dynamic variable speed control system, in the process of injection molding, it can make a different frequency output and accurately closed loop control the pressure flow, pressure on different traffic, realize injection molding machine high speed response and the best match of energy demand and adjust automatically.
It has three advantages:
1.Energy saving
The servo motor of servo injection molding machine is according to the need to change it, don't like the three-phase ac asynchronous motor speed and torque is invariable, and the output of the motor power = torque X speed, thus achieved the effect of energy saving
2.High precision
Servo motor injection machine adopt pressure sensor, the controlling system can real-time control through the feedback signal of the pressure sensor, make each stage of the required pressure, rapid flow, and accurately.
3.Efficient
Due to the response speed of servo motor, from zero to rated speed just + / - 0.5 milliseconds, so the efficiency of the processed products increase by about 2%.
