1. An aluminum air-cooled engine cylinder head for a single cylinder, 2-stroke engine is to

be die-cast. The overall diameter of the cylinder head is 101.6 mm. If the projected

plan area of the runners and gating system is 100 mm2 and the casting pressure is 10

MPa (1500 psi), what minimum locking force is required for the die-casting machine in kN.

Solutions

Expert Solution

In die casting, the cavity is clamped. The clamping force required is calculated as follows

- Initially calculate the total projected area of a cavity- it includes the part area and aslo the riser area

- Then determine the number of cavities(In this case 1)

- When the molten material is pored into cavity, the force that tries to  separate is equal to pressure in the cavity *the area
