 For injection molding machine has two kinds, vertical injection machine and horizontal injection machine,Most of customer would like choose horizontal injection machine more than vertical injection machine, below following have some features of vertical machine to help us understanding about vertical injection machine:

1, Injection device and clamping device in the same vertical center line, and the mold open and close along up and down direction. It covers an area of only about half of the horizontal injection machine; so it will be save place than horizontal injection machine.

2, Easy for inserted molding, because the mold surface up, it will be easy for insert put into the location. But now more advanced horizontal injection molding machine also can be a very good implementation inserted molding.

3, In vertical injection machine, Mold by horizontal template bearing the weight of the upper and lower opening and closing action, so, It will be advantageous to the durability maintain machinery and mould precision.   
4, considering some plastic part have specific design, choose Vertical injection machine easy for robot take out part, easy to configure all kinds of automation equipment.
5, Suited for small type mould production, with simple mold structure, and convenient for unloading.
6, Stood the test of many earthquakes, vertical injection machine has good vibration resistance.
vertical injection machine
Injection molding machine through continuous technological progress and update, horizontal injection molding machine and vertical injection molding machine has similar function.

PVC injection machines is the same as common injection machine in the working principle and structure, but there are some differences in PVC machine, let's look at why there are different, and where is the differences.

There are several fan on PVC machine barrel, that is used to cooling the barrel cool, because PVC plastic should begin to decompose when the temperature reaches 130-150 degrees, if it is decompose, PVC will producing toxic chlorine gas. So the fans allow us to better control the barrel temperature. The big machine barrel will have water or oil cooling system.

PVC plastic is strongly corrosive, so the injection molding machine screw and barrel must be stainless steel. And in order to ensure product quality, the machine is nozzle is bigger than common machine, and it is hard chrome plated.

In order to achieve the required screw torque during PVC plasticizing, achieve efficient plasticization; PVC molding machine oil Motor is bigger than ordinary machine.

Because most of the pipe fitting mold has core pulling, the mold is relatively wide, the door of PVC machine is widened (optional); in addition, some pipe fitting mould have more core pulling, so PVC injection molding machines can add more pulling group.

We can provide customized PVC injection machine, if you need, please contact us, we can also provide PVC molds, as well as PVC injection molding production.

DKM PET injection machne

When choose a suitable cavity number preform mould and PET injection molding machine size,first we have to know the quantity requirement each hour for certain size PET preform.For example,20g PCO28 preform,need 8000pcs each hour,if the cycle time for the PET preform molding line is 20s,we have to make 32cavity preform mould,with DKM330 PET injection molding machine.If the mould cavity number is different,the cycle time will have a little different.But the main reason which affect the cycle time is the weight of PET preform mould.
