PVC injection machine
Special PVC pipe machines designing, due to the raw material has a low moisture sensitivity, however better result can be seen when PVC is dried for 4 hours in a dehumidified dryer at 65- 75 degree. based on raw material features for machine designing, we developed the PVC injection molding machine must ensure the special requirement of PVC products:
1.Hard chrome plated screw, nozzle to ensure the quality of PVC production and extend the life of the mechanical parts, all components are highly anticorrosive.
2.Widened safety door design, equipped with double core pulling devices.
3.Enlarged hydraulic motor, to fit the high torque requirement of PVC plasticization.
4.Melt temperature is critical in mouldingPVC, melt temperature is different from heater band temperature.
5.Oil cooling and water cooling system in screw and barrel for large-sized machine.
Using PVC pipe machines, it is very important to purge barrel of injection molder with GP ABS, Acrylic, PE before and after the use of PVC compounds. The injection machine must not be shut down with PVC in the barrel. If the material is left in the barrel, it will degrade and the screw and barrel will have to be removed and cleaned mechanically.
Welcome to contact me if you have related PVC projects, we are sure to offer you the best price.

Choose a suitable injection molding machine
Are you looking for a reliable injection molding machine manufacturer?
As we know, there are too many injection molding machines in China or aboard, when you start a new project and needed injection molding machine, so it is very important to choose the most suitable for your production.
Firstly, choose a right machine type. you must consider about your plastic product product raw material, the important factors when choosing a plastic injection molding machine, the special raw material have special machine screw and barrel, for example, PET and PVC, PC raw material, it has special machine type.
Secondly, the mould can be each load, important factors when choosing a plastic injection molding machine, include mold, plastic product, molding requirements and so on, therefore, you need collect or have the following information before making a choice: mold dimensions, height, width and thickness, weight, special design. Mold requirements, such as quality condition, production speed and so on.
Thirdly, the mould can be easy to take out, the mould width and height must be less than or at least less than the internal spur of large column, the mould width and height must in the mold plate size range, the mould thickness should be between the thickness of plastic injection molding machine max. mold height and opening stroke.
Fourth, the machine has enough clamping force and enough injection speed.

There are more and more injection molding machine manufacturers in China. So the injection molding machine industry has fierce competition, how to stand out from such fierce competition? Now there are several famous top injection molding machine manufacturer in China, like Haitian injection molding machine, Yizumi injection molding machine, Chen Hsong injection molding machine, why they are so famous? How they develop their business into such large scale?
First, quality is one of the main factories.
Second, besides quality, after sale service is important as well, it is a main part. Generally, machine price includes two parts, machine quality + service. Even you have very good quality, but your service is not good, you will lose of customer.
Third, delivery time, if you can offer customer machines in a very short time, it will also gain the order, because that mean the customer can use machine to earn money earlier, time is money.
So if you want to be top injection molding machine manufacturer, you must achieve above 3 points. Dakumar injection molding machine is go for above 3 points, so it must be top machine manufacturer in near future. If you have any plan to buy injection machine, pls don’t hesitate to contact us.
