Zero-molding is a unique technology that reduces molding defects and saves energy with simple operations.
It consists of three elements: MCM (Minimum Clamping Molding), which enables filling with low injection pressure, FFC (Flow Front Control), which enables molding with low mold clamping force, and SPS (Simple Process Setting), which allows these to be easily operated.
Here is a video that explains the overview of Zero-molding.

*MCM - Minimum Clamping Molding
*FFC - Flow Front Control
*SPS - Simple Process Setting
Issue: Conventionally, in order to completely fill cavities, the screw was pressed forward and filling done at high injection pressure, but high filling pressures made it easier for flash to form and threw off cavity balance, which tended to cause short shots.
The defects that resulted from these issues wasted both power and materials.
Issue: One thing that users can do to prevent flashes and other defects is to set a high mold clamping force. However, too much force inhibits the escape of gas, which leads to short shots and burning. It can also stress molds, which can impact mass-production in various ways. Also, it increases power consumption, which is not economically helpful.
Issue:Molding requires a wide range of knowledge and skill. Molding machine features must be set and used properly. Incorrect settings or operation can cause problems in mass-production that decrease work efficiency and cost users time, material and power. Moreover, complicated operations can only be performed by apt operator.
