CALCULATE THE CLAMPING FORCE ACCORDING TO THE SHAPE OF THE PRODUCT.

1,Calculate the clamping force p according to the vertical projection area of the injection molding machine product on the template (fixed template or movable template): clamping force 2 clamping force constant x product projection area p 2 KpS were p ― clamping force (t) S ― a projected area of the product in the vertical path of the template (cmZ) Kp ― clamping force constant (T / cmZ).

2,Plastic name PS, PE, PP, ABS, PA, POM, PMMA Other Kp (T / cm 2) 0. 320. 3-0. 480. 64-0. 720. 64-0. 720. 65 A 0.80.6 A 0.85 .The mold opening stroke of the injection molding machine is determined by the product height. The mold opening stroke Zx product height + nozzle length.

3.According to the material of the product and the wall thickness of the product, select the screw model general plastics such as PE, PP, PS, ABS, etc., for the products with thinner wall thickness, choose A and B screw engineering plastics such as PC, PMMA, PPO, etc. For products with thicker walls, choose B and C-type screws.

4.According to the contour size of the mold, the inner spacing size of the tie rod (guide pillar) of the injection molding machine is determined. The mold width of the minimum mold thickness and the inner distance of the tie rod (10-20) mm. The minimum modulus of the plastic injection molding machine.
