How to choose injection machine China for your product?

Choosing a suitable injection machine China is very important when we start a new production line.
Then what we should take into consideration when we select injection machine China?

• Product and raw material of the product

First, we should be clear that what product we will manufacture. If we want to manufacture daily use commodities, standard injection machine China is OK. But if we want to manufacture PVC pipe fitting, then we should choose PVC injection machine China. Pet injection machine China should be chosen when we want to manufacture packaging bottle.

• Special requirements

In some countries, power is very expensive. Thus we may want to choose power-saving injection machine China, such as servo power injection machine China series or variable pump injection machine China from Dakumar Machinery Co, Ltd. Or we may choose dual color injection machine China if we want to manufacture dual-color products.

• Mold height

Mold size is very important factor. Several aspects may influence the mold size such as cavities, products design.
The mold height should be larger than the minimum mold height and smaller than the maximum mold height.

• Toggle stroke

Toggle stroke should be long enough to ensure that product can be picked out.

S----the maximum toggle stroke of injection machine China
H1 ----ejector stroke
H2---- the height of the plastic product and the runner system

• Clamp Tonnage

When plastic is injected into cavities, high pressure will be produced to push cavities and core away. So the clamp force should be enough to keep the mold tight.

• Shot volume

Shot volume should be chosen according to product grams and cavities. Generally, the total product weight in one mold should be less than 70% of the shot volume.

• Injection pressure and screw diameter

Some special plastic requires high injecting pressure. So it's very important to choose suitable screw diameter. Usually, small screw diameter means high injecting pressure.
