To invest a new plastic injection molding line, time and profit is the most key factors to consider when purchasing new injection machine and plastic injection molds. In this way, plastic molding line cycle time is very important, it not only request injection molds with good cooling system design, also need a good performance injection molding machines.

Sino holdings offers high quality injection molds, also supply with various injection machines, we would be your best choice for your new projects. For the same molding line, compared with competitors, cycle time less would be all profits. For mold design, we not only design with best cooling system, also can suggest choosing cube for thick area which need more cooling times. When fit with machine, only good cooling is not enough for fast cycle molding. We need to make sure mold with high verticality. So when mold fit on the machine, it would work very smooth.

In addition, for a fast cycle time molding line, you need good performance injection molding machines. we have our high speed machines with servo motor, high energy saving, high precision, high stability. For same mold, when fit on standard machine and high speed machine, the cycle time would differ very much. Also for a molding line, we can use other auxiliary machinery for fast cycle, like connect cooling waters on mold with separate channels, or can connect mold cooling with chiller instead of normal waters. Also for PET molding line, we can use robot for pick performs out cooling after injection, it save a lot on cycle time and make the molding line high productive. Pls do not hesitate to contact us for injection machines and molds for fast cycle molding line.

By providing the best molding cooling system, production productivity can be increased a lot. The cooling system is not only refers to the design, in the mould design stage, we need to make the optional cooling design, and ensure after injection molding, the plastic parts will be cooled down in shortest time, cooling ways should be sufficient, and the cooling line diameter should be big enough.

When the mould cooling layout is sufficient, in the production stage, there are two factors also affect the cooling, one is the cooling connection, workers can connect the water pipe in different ways, direct in and direct out is the best way; second is the cooling facility,cooling facilities are needed for injection molding factory, this is not only for reducing the cycle time,but is also necessary for mould and machine life,and affects the products quality as well.we suggest customers to prepare big cooling tower with water pump, and also water chiller. Dakumar Machinery offer cooling facilities and other molding auxiliary equipment along with injection machines.

 Productivity is one of the most concerns from customers, especially for customers from European and American countries, because injection molding cycle time is money and profit. When we are talking about the productivity efficiency, we always focus a lot on the injection molding machine performance, but actually sometimes when we run the production in high speed machine, we found the cycle time was effected by mould, because machine is waiting there for mould.

As per my experience, the production cycle time is effected by many factors, like plastic material property, steel property, injection system, mould cooling system, mould ejection system etc. regarding the cooling system, the optimal cooling system should provide the function to cool down the plastic parts in the shortest time, and the cooling effect should be balanced. For ejection system, ejection by hydraulic cylinder will be slower when compared to mechanical ejection. All those factors which affect the production time need to be carefully considered and discussed during mould
design stage. If you have high expectation for the injection molding cycle time, please come to contact us.

Dakumar Machinery is a leading plastic injection molding machine manufacturer in China, one of the first companies start R&D of CE hybrid injection machine. Now we are offering the best hybrid injection machine among Chinese injection machine manufacturers.

CE hybrid injection machine is developed from hydraulic injection machine. Electric servo motor is used for material charging. There are another 2 servo motors in our hybrid injection machine, one for mould opening & closing and one for injection and ejecting. This hybrid injection can save a lot of energy.

Compared with normal injection machine, our hybrid injection machine has many advantages. Clamping system is much strong then normal machine, as because we need high pressure high speed injection. Machine frame (base) is much stronger, because the clamping plate will open can closing in very high speed, so it need heavy and strong base to support such high speed moving.hydraulic system is much more complex, we need increase many high level valves.

To meet different requirement of different customer, we also offer many optional functions for our machine, for example CE standard, which is made for better safety consideration. CE standard machine has strict requirement for the injection machine, such as screw cover, all closed plate, hydraulic pipe lock, etc.. All of these are designed for improving the safety reason. Besides CE option, there are also some other option like moog servo valve, hydraulic nozzle, extra set of core pulling device, bi-metal screw, etc..

For more information of CE hybrid injection machine? pls contact me.

The most common questions customer ask for chair molding machine is : .
What size of injection molding machine should I buy for making chairs? which screw is suitable for chair molding? Is your machine power saving ? What’s the cost of the machine ?

The answer for the first question, size of chair molding machine depends on chair size and chair weight. Usually chair weight around 680gram(byby chair) we suggest to produce on DKM-380 , for normal adult chair, chair weight around 2300g, we suggest to produce on 780ton machine. For special big size chair, chair weight over 3000g, we suggest to produce on DKM1080.

The answer for second question, which screw is suitable is suitable for chair molding ? For chair molding, we suggest B screw.

The answer for third question, Yes, our machine is power saving, because our machine equipped with servo motor. It can save electricity from 20%-80%. Power saving is the one of the very important thing customer concern, because saving electricity equal as saving investment cost.

The answer for last question, what’s the cost of chair molding machine? Chair in different size request different injection molding machine, so chair molding machine cost is depends on the machine size, if machine size bigger , the price is higher.

If you want the detail price, please show us chair sample, we will give you the quotation and advise!
