Plastic Injection Molding Machine
Striving for excellence
providing complete injection molding strategy to meet customers' requirements

Offering a complere configuration system,users can choose a suitable plastic injection molding machine in terms of different requirements

Plastic Injection Molding Machine - Blog

In plastic industry, injection molding is very popular, we know injection machine have various clamping fore with ton, various injection weight etc…but how to select a suited injection machine for your plastic products?
There have some key points we must be considering when select injection machine, please considering following:
1. Select right type of injection machine
The type means you should be know the plastic martial or product requirements, such as PET need PET special injection machine, PVC need PVC special injection machine, thin wall or mass-quantity consider High speed injection machine and so on…
2. Tie bar distance
This distance will decide your mould can put into injection machine or not, so we must be know the suited mould dimension, usually, the mould length or width which size below to Tie bar distance will be ok, need analyze according to different mould. 
3. Clamping force
This is very important for injection machine, when making injection we will considering enough clamping force for part, if the clamping force not enough, the flash will easily happens to your plastic product, or cannot injection smooth.
Clamping force= projected area*cavity*in mould pressure around 0.35kg/cm2.
4. Opening stroke
Usually, the opening stroke will double distance of plastic product height, because mould core height and plastic product moving distance; some time if customer need robot for IML it will need 3 times distance of plastic product, but need overall consideration the robot system.
5. Injection weight
Must be considering plastic product weight, if the injection weight not enough the produce will easily starved feeding. choose injection weight can refer this way: 
Injection weight of injection machine= part weight*cavity*1.35
please contact us we will give good solution for select injection machine and injection molding solution.
Dakumar Machinery have more than 10year injection molding experience, welcome down visit us.

With well developed thinwall molding, high speed molding machines are very popular in plastic injection molding industry, in order to satisfy large demand for disposable plastic part molding.

For the thinwall molding, we know that usually the cycle time is within 10s, if we could reduce 1s in each cycle, we could raise the production rate 10%, this is a big profit in the injection molding industry, that’s why we choose high speed injection machines for thinwall molding.

For the thinwall mould, we have to use the injection molding machine with high speed injection in order to get successful injection., especially for the high container, the thinwall part cooling very fast, we use high speed injection machine to get qualified plastic parts.

high speed molding machine

Compare to common injection molding machine, the injection speed is fast because it has an accumulator on the injection machine, it could get high pressure during injection. Some high speed machine could do mould open, mould ejection and material charging at the same time, it could save 1-3s each shot. We call it hybrid injection molding machine.

Sino Mould could offer you one stop service for thinwall molding line, include IML thinwall molding line and multi-cavity thinwall line with technology support and staff training. Please feel free to contact me for more information. Thanks.

Injection machine clamping force is one of most important key point for injection machine. Injection machine clamping strength refers to the maximum strength of the machine plate to clamp moulds,so we need to consider the clamping strength molding plastic when purchase machines.

Injection machine clamping capacity is especially important when producing thin wall products, because the thickness of the parts are thin,if the clamping force is not strong enough, when mold close and do plastic injection, the molding area is hot, and internal pressure will push to divide the core and cavity, in this case, if the clamping strength is not big enough, flash will easily happens to the plastic parts. So clamping strength of molding machine needs to be considered in molding different plastic products. But it is also not good to put small moulds in big machines,if the clamping force is too big, the mould plates will bend after long time production under big pressure.

Precision injection molding machine maker, Dakumar developed precision injection molding machine which can injection precision products, with high stable and precision injection, is China precision injection molding machine innovator.
Precision injection parts like electric parts, plastic gears, mobile phone covers, LED Light pipes etc… These parts required precision and stable injection weight, that is why we developed precision injection molding machine.

Our precision injection molding machine adopted advanced Euro brand-KEBA 1000/2000 as our computer controller, can accurately control the location and temperature, except this, we use MOOG valve to control the injection system to make sure the injection pressure and weight in the precision status and the injector moved on the smooth rail to make sure the injector move in a level.Our precision injection molding machine also has other advantages like high speed, high safety, high efficiency and high saving power. If you want to make thin wall production like food containers, disposable forks, knives, spoons, our precision injection molding machine also a good choice.

There are hydraulic injection molder and servo injection molder, the main difference is that, hydraulic injection molder is driven by hydraulic motors, the hydraulic motor is continuously moving during the whole production; The servo injection molder is driven by servo motors, the motor would not work unless get the order from servo driver. As we known, the power consumption of injection molder is quite big, and during real production, the servo injection molder can save at least 20% of power, the most can save 80% of power.

Compared with hydraulic injection molder, servo injection molder have other advantages:
1. With servo power system, close-loop controlled, the injection precision improved
2. Smart servo power system, the reset time only needs 0.05s, quite rapid
3. More quiet in low speed movement
4. More wide scope for holding pressure time
5. Super stable oil temperature, reduce oil cooling requirement.

Dakumar Machinery developed servo power machine, and also applied servo power system into the high speed injection molder. This high speed & servo power machine can realize mold opening, ejection and raw material charging at one time, the machine cycle time can be reduced to 3s, If make disposable products, the production quantity can be rapid increase.
Welcome to contact us for knowing more about servo injection molder as well as high speed injection molder with servo power system.
