If you want to buy a injection molding machine and you are also strict with your product yield, DKM Servo power injection molding machines will fit with your requirement. Our company has more than 8 kinds of the injectionmoldingmachines, every kind of the machine has its own feature, once customers ask for the quotation, we will as per the products, working time , product yield to choose the suitable injection molding machine.
Usually, we will suggest servo machine, let me describe the advantage of the servo machine, Compared to standard injection molding machine, we use MITLR for computer controller, servo motor and gear pump of the servo power injection molding machine, which can save 30%-70% power of the servo power injection molding machine. Advantage of the servo machine is it will control the power and oil when it working and will not offer the power when they are not working, it has its own control.
Even the price is higher than the iml injection machine, but in the long term, you will get the benefit shortly in your working time. This is the advantage of the servo machine.
If you are interested in our servo power injection molding machine, pls feel free to contact me.

To have injection machine safeguard is very necessary, there are many accidents happen in the worldwide during the machine opening and ejection. That is also the reason why now in most of European countries, only CE standard molding machines are accepted by the custom.

I have one customer told me that the accident happens last week when he use one Chinese brand plastic injection molding machine. Under semi automatic status, the worker open the door, but the machine does not stop, mould open and ejection continues, the worker was hurt . but he thought if he open the door, all the actions will be stopped. Since this, the customer now requests all machines must includes the opening and ejection safeguard to make sure that no matter under semi automatic or fully automatic status, if open the front door, the machine will stop at once, no any action will be taken including the mould opening, ejection etc. But the machine is still under heating, and motor still works.

If you have the same requirement, pls send email todkm@dakumar.com

Dakumar injection molding machine company is a professional injection molding machine manufacturer in China,we have different types injection molding machines,such as Servo power saving machines,high speed machines,hybrid injection machines and so on.

For the servo power saving machines,it could save 20-80% power consuming compared with common pump injection molding machines.especially for the big parts need long time cooling.Servo power saving injection machines also have high requirement for the power supply,the voltage must be stable,otherwise it is not good for the servo motor long time use.

Dakumar Machinery have a new type machine called hybrid injection molding machine,this is with high safety, high speed injection,high power save,high precision and high stablity.Hybrid injection molding machine is suitable for thinwall products molding.

We could offer you one stop service for the injection molding line,please contactif you have new project.Thanks.

When we make injection molding production we will meeting different problem, it will delay the production, now let us study some frequently asked questions:

Observation-1    Poor Knit Lines

Cause-1  Poor venting.  Solution:  Place vents at last place to fill and at converging flow fronts

Cause-2 Too cool a melt.  Solution:  Increase the melt and/or mold temperature.

Observation-2    Part Sticks During Ejection

Cause-1   Insufficient ejection force.  Solution:   1.Increase mold closed time. 2.Reduce mold temperature. 3.Reduce process temperature. 4.Reduce pack and hold pressure. 5.Sandblast "B" side. 6.Increase size of ejector pins. 7.Increase number of ejector pins. 8.Increase draft on part.9.Provide air assist.  

Observation-3    Bubbles

Cause-1  Gas entrapment.  Solution: 1.Relocate the gate or modify the flow path.  2.Add a pin in the area to eliminate the gas trap.

Observation-4    Part Sticks in "A" Half or Stationary Side of the Tool

Cause-1  Insufficient extraction force.  Solution:   1.Sandblast "A" side of tool. 2.Polish "B" side. 3.Run "A" side cooler. 4.Put keepers in "B" half of tool. 5.Increase draft on part in "A" half of tool.

Observation-5    Warped Parts

Cause-1  Anisotropic shrinkage.  Solution:   Relocate the gate so flow occurs in only one direction.

Cause-2  High molded-in stress.  Solution:   1.Increase the process temperature. 2.Reduce the pack pressure.Increase the mold temperature.

Observation-6   Surface Defects/Uneven shine/Beach marks

Cause-1  High molecular weight compound in highly polished mold.  Solution:   1.Change to a lower molecular weight compound. 2.Texture mold cavity surface (EDM, sandblast, etc.)

Observation-7    Silver streaking or splay marks

Cause-1  Contaminated material.  Solution:   1.Check for moisture (condensation) or dry the material. 2.Check regrind for contaminants or moisture. Dry if required  3.Reduce injection speed.

Observation-8  Part Flashes  

Cause-1  Too much injection pressure.  Solution:   Reduce injection pressure and time.

Cause-2  Too much material.  Solution:  Decrease shot size.

Cause-3  Material viscosity too low.  Solution:  Reduce injection speed.

Cause-4  Tool too loose  Solution:  Machine or dress the parting line.

Cause-5  Not enough clamp capacity.  Solution: 1.Use a higher viscosity compound. 2.Increase clamp tonnage.3.Reduce thickness of the vents. 4.Move to a larger machine.

For more information will be update…please kindly to contact us if you have any help during the injection molding production.
