Clamping Unit
General
1. The theoretical shot size is based on the cross-sectional area of the screw multiplied by the stroking distance of the screw. 2. The shot weight is calculated for PS and is based on 90% of the theoretical shot size. However, the actual shot weight will depend on the molding conditions and mold distance. 3. The cooling water consumption varies according to the resin used on the molding conditions. The above value is an approximate figure in normal operating conditions. 4. Plasticizing capacity is based on PS resin. 5. The above specifications are subject to change without notice.

Spec.
1. The theoretical shot size is based on the cross-sectional area of the screw multiplied by the stroking distance of the screw. 2. The shot weight is calculated for PS and is based on 90% of the theoretical shot size. However, the actual shot weight will depend on the molding conditions and mold distance. 3. The cooling water consumption varies according to the resin used on the molding conditions. The above value is an approximate figure in normal operating conditions. 4. Plasticizing capacity is based on PS resin. 5. The above specifications are subject to change without notice.

Mechanical Characteristics - 20 ~ 25% REDUCTION IN FLOOR SPACE The compact design of the clamping system reduces the footprint by 20% ~ 25%, compared to toggle machines.
- REDUCTION OF HYDRAULIC OIL FLOW - BY 25% The special mold-locking cylinder reduce the amount of hydraulic oil circulating in the machine by 25%.
- MACHINE WEIGHT REDUCED BY 10% Since tail stock platen is no longer required, the weight of the machine is reduced by 10% without any sacrifice in the rigidity of the machine frame.
- MINIMIZATION OF PLATEN DEFLECTION ALLOWS FOR ULTRA-PRECISION MOLDING The special clamp design concentrates the clamping force at the center of the mold, thus minimizing platen deflection.
- ADJUSTMENT AND DIE HEIGHT ADJUSTMENT The die height and mold clamping force can be set easily and quickly via keyboard.
- INCREASED MOLD THICKNESS AND MOLD OPEN STROKE The PRO-DIMA machines can accommodate thicker molds with a longer mold opening stroke.
- HIGH SPEED MOLD OPEN / CLOSE The opening and closing cylinder are independent of the mold locking cylinders, thus increasing the speed of mold open and close movement. LOCKING

1. The theoretical shot size is based on the cross-sectional area of the screw multiplied by the stroking distance of the screw. 2. The shot weight is calculated for PS and is based on 90% of the theoretical shot size. However, the actual shot weight will depend on the molding conditions and mold distance. 3. The cooling water consumption varies according to the resin used on the molding conditions. The above value is an approximate figure in normal operating conditions. 4. Plasticizing capacity is based on PS resin. 5. The above specifications are subject to change without notice. DONGSHIN /

General
1. The theoretical shot size is based on the cross-sectional area of the screw multiplied by the stroking distance of the screw. 2. The shot weight is calculated for PS and is based on 90% of the theoretical shot size. However, the actual shot weight will depend on the molding conditions and mold distance. 3. The cooling water consumption varies according to the resin used on the molding conditions. The above value is an approximate figure in normal operating conditions. 4. Plasticizing capacity is based on PS resin. 5. The above specifications are subject to change without notice. ※ Machine of all kinds of tons can be produced by request of user DONGSHIN / 35page
