How do you calculate injection capacity?

To calculate the injection stroke or shot size, we can put all values in the formula of shot volume, i.e., Shot Volume = π x r2 x Shot Size. Here, r=1.4 and shot volume is 26.71 cm^3.

What is tonnage of injection molding machine?

Normally, the injection molding machine clamping force rating is stated in tonnage. A 200-ton machine, for example, is capable of producing a maximum clamping force equivalent to a total of 200 tons.

What is all electric injection Moulding machine?

In all electric injection molding machines, (AEIMM) all process relevant movements (recovery, injection, mold open/close) are executed via electric (servo) motors. The use of electric motors allows for a highly energy efficient machine as the motors are only actuated when the movement is needed.

How do you calculate tonnage in injection molding?

Now you can calculate necessary tonnage based on the projected area times the clamp factor for the material used. T = A x cf. For example, the projected area of the molded part is 150 sq/in times a clamp factor of 3 (tonnage needed/square inch from material data sheet). 150 x 3 = 450 tons needed.

What is injection rate in injection molding?

Injection rate refers to the volume flow rate that can be achieved per unit time at the time of injection, such as the ratio of injection capacity and injection time.

How do you calculate injection molding tonnage?

What are the reason from the following that makes sense to mold with all electric injection molding machine?

Many of our customers prefer All Electric Injection Molding Machines based on the following: The highest degree of cleanliness. Very low energy consumption. Very high repeatability and precision.

What is hydraulic molding machine?

Hydraulic Plastic Injection Molding. These types of machines employ hydraulic cylinders to clamp together two halves of a mold at high pressure. Plastic substrate pellets are then melted, and the liquid is injected into the mold cavity.

How do you calculate clamping force of injection Moulding machine?

For example, a product has a projected area of 410 cm2 and material is PE, calculate clamping force. Calculated by above formula: P = Kp * S = 0.32 * 410*1.1 = 141 (T), 150 ton injection molding machine should be selected.

How to calculate the clamping force of an injection molding machine?

There are 4 clamping force calculation formulae to calculate the clamping force of an injection molding machine: Clamping Force Calculation Formula 1: Empirical formula 1 Clamping force (T) = Clamping force constant Kp*product projected area S (CM*CM)

How to use the injection moulding calculator?

The other way to use the calculator is given the shot weight of a particular mould, alter the injection capacity of GPPS until the injection capacity of the material you want to use falls within the recommended 25\%-65\% range.

What is the injection capacity of the injection molding machine simple by WX?

But you can’t decide the injection capacity of the injection-molding machine simple by Wx, you have to exchange it into Wps. The formula is: Wps=Wx × 1.05 In which, Vx represents the specific gravity of certain plastic.

How to calculate the injection capacity of a plastic product?

If the product is made from other plastic (named X plastic), calculate the theoretic injection capacity of the plastic, Wx, based on the aforesaid formula: Wx= (1.3～1.1) × (product weight + total weight of the runner system) But you can’t decide the injection capacity of the injection-molding machine simple by Wx, you have to exchange it into Wps.
