To lock the maximum of the mould clamping force said. Shoot for forming space (cavity) material pressure ACTS on the direction of the open mold, we must under the clamping force, usually materials under pressure should be 80% of the clamping force. Material is forming space per unit area of parallel pressure forming space projection area of the product. Forming space per unit area of average pressure varies between injection mechanism, plunger ㎏ / ㎝, about 400-400 screw ㎏ / ㎝. About 250-250.

1) empirical formula:

Clamping force = forming space per unit area of average pressure forming space projection area x x factor

= 330 kg/cm * finished product long wide x 1.5

Note: 1. The finished product length, width unit for cm;

2. The calculation of the clamping force of the unit is kg, divided by 1000 for the injection machine tonnage (T);

3. A
