What can be done with our processing technology: Control of the sled.
Achieved the elimination of warping and deformation with our independently developed IMM method, creating reliable parts without variation between shots.
The elimination of warpage and deformation in plastic molded products is an eternal theme. One of the advantages of plastic molding technology is the freedom of shapes that can be molded, but this can lead to warpage and deformation. Particularly, once a mold has been created, the countermeasures are limited, resulting in defects that trouble manufacturers. **Main Causes of Warpage** - Uneven mold temperature: Molds are operated at temperatures lower than the melting resin temperature to cool and solidify the molten resin. At this mold temperature, partial temperature differences occur due to the product shape and component structure. This disrupts the cooling balance of the parts, resulting in deformation during demolding. - Flow direction during injection: In injection molding, the shrinkage rate may differ between the flow direction and the perpendicular direction. This is particularly evident in fiber-reinforced resins. The unevenness of this shrinkage leads to warpage and deformation. - Uneven filling pressure: When injecting the molten resin into the mold, the filling pressure can be uneven. For example, the pressure is high near the gate, while it is lower on the opposite side of the gate. Additionally, areas with thin product thickness experience higher pressure, while thicker areas have lower pressure.
