SCS (Sequential Cavity Separation) molding (Family mold molding)
High response valve control injection condition automatic compensation system
Sequential injection using a strong two-platen high-precision mold clamping mechanism for unbalanced loads inside a mold!
Advantages for the customer
- Reduce expenses and the number of molds by means of changing to one mold.
- Easy part management and color matching through the use of simultaneous molding.
- Low mold clamping force through the use of sequential injection for each cavity.
- Easy production of small lots through the use of cavity selection molding.
System Features
- Injection conditions for a maximum of four cavities can be entered.
Six speeds, six pressures, and three holding pressures common to each cavity.
- Automatic origin point compensation for injection start position for each cavity
- Valve gate open/close timing is coupled to the injection completion.
- Displays independent injection speed and pressure waveforms for each cavity.
