Why developed high speed hybrid machines for thin wall products? You can find the answers on the products themselves.

What are the mutual features on thin wall products? Thin wall,disposable,large production quantity.
What are the mutual features on thin wall molds? Nice cooling system, runner system and air venting system.
What are the requirements on the injection molding machine for thin wall products? 
1. Need high speed injection to fill the mold cavity rapidly by high pressure response accumulator;
2. Need servo power system to save power consumption so that the cost of production can be reduced;
3. need hybrid controlling system to realize mold clamping, ejection and plastics charging in the same time so that the thin wall products makers can get as many as goods in one hour.
Dakumar developed high speed hybrid machines with 5 highs: high speed, high energy saving, high injection precision, high stability and high safety, is devoted ourselves to offer a fine solution for how to realize the cost-optimal production in thin wall molding line.
If you are finding high speed hybrid machines manufacturers in China, or want to find a Chinese suppliers who can offer all the facilities for thin wall molding line,welcome to contact Dakumar.

Dakumar Machinery is a professional injection machine manufacturer who offers PET screw injection machine, PVC screw molding machine, PA screw injection machine, PC screw molding machine, etc.

Injection molding machine screw is divided into: Tapered screw, Mutation type screw, general screw.

Tapered screw
Refers to the depth of screw channel from the feeding section gradually over. to the screw slot homogeneous section. That mainly used for processing has a wide range of softening temperature, non crystalline materials with high viscosity, such as polyvinyl chloride.
Mutation screw
The screw groove depth from deep to shallow process in a shorter axial distance. It is mainly used for processing plastic viscosity, melting point, crystallization of obvious such as polyethylene, polypropylene.
General screw.
It’s compression length between the mutation type screw and tapered screw, but the fusion quality and energy consumption is not as good as them. Suitable for crystalline and non crystalline plastics melt requirements.

For general plastic material without flame retardants material, using general screw is enough. Only need to choose a different screw diameter depending on the melt viscosity. But for special plastic material, special product, or special plastic particles, they must use special screw & barral.

Any question about special plastic injection molding machine & injection machine screw, pls contact me.

Dakumar Machinery Co., Ltd, the leading plastic machine supplier in China, founded in 1992 and located in Huangyan, China mold town. Dakumar machines production catch around 3000sets of different tonnage machines for selling to different counties, suck like Brazil, Mexico, Russia, Egypt, Turkey and so on, also set up their service center in some countries.

To get the long life time for injection molding machine, as these machines are widely used their maintenance, efficiency and uniform production of products are some issues that should be kept in mind.

A deep understanding of your plastic injection molding machine and how it works is highly recommended, this is important both for the producer and the people depending upon products made by your machine.

To keep your machines working correctly and smooth, you have to care for them, you should screw tight the machines every day before using it, and after some times production, suck like one month, you need to add the lubrication oil. If there is any abnormal, you must stop the production immediately and check where is problem, make sure 100% no problem and then you can start your production again.

If you need any details maintenance for injection mold machine, welcome to contact Ms. Rachel, thank you!

Usually, the 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, in obtaining the above information, you can follow these steps how to choose a suitable plastic molding machine:

Choose the right type of plastic injection molding machine: make decision by the plastic products. The plastic injection molding machine has a lot of types, you should determine that what kind of plastic raw material for the product, the production requirement to choose the mold cavities to confirm the machine tonnage. For example, for the thermoplastic raw material is PET, the product is single color, one hours production needed 2000pcs, in additional, some product requires high stability, high precision, high injection speed, high injection pressure and rapid production and so on.

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.

Dakumar Machinery Co., Ltd is one of the leading injection machine manufacture in China, if you need any help, pls feel free to contact me.

Sino holdings group expertise in making high speed molding line solutions, especially for thin wall IML high speed turnkey solution offer. we supply with turnkey molding lines, for example IML molding line, we support with IML injection molds, high speed injection machine suitable for IML molds, IML robot for label sticking and product picking up, IML molding auxiliary machines.

For a IML container molding lines, we need production equipments as blow:

1st, container IML molds: first we need to calculate the mold dimensions according to part size, for container with 142X90X43mm square container, with 4 cavities, mold dimension need to be around 800X660X580mm as for each cavity self locking mold structure. Usually for these high speed injection molds, we choose with hot runner system and mold is designed a little more stronger than daily use molds to bear long time fast speed high pressure moldings.

2nd, on this injection machines, with high production quantity, we suggest with our high speed high energy saving machine SN-300 ton. we first need to check mold is ok to fit on this machines and also we would calculate if machine clamp force is enough or not for such mold running. Also the machine space if ok for IML robot working stroke. Based on this high speed machine, we have another option which equipped with Moog valve, with this component, the machine is more precision and accurate, benefit for low production reject rate.
3rd, if for high speed molding line, the robot usually we suggest with side entry which is fast response and short dry cycle time. Our robot only need 1s for all workings include IML label put on the mold core and picking up final products.
we offers high speed molding line, also include service for molding line installation and training on using it. If you are interested, pls feel free to contact with me
