Injection molding system of low clamping
Substantial cost-down is possible
for large space & thin-section high-precision & high quality plastic molded products.
Plastics: polycarbonate, Plastics temperature: 300°C, Mold temperature: 105°C, Sample size:316×211mm, Section thickness：0.5-2.0mm (variable)
|Sample No. / compression||Die
|Test 1||Thickness 1.0mm/
|Test 2||Thickness 0.8mm/
|Results at section thickness 1.0mm||Results at section thickness 0.8mm|
Test 1 proves following;
While conventional injection molding needs 50 ton die-clamping pressure, injection compression molding needs only 1/5 pressure to ensure perfect molding with 100% plastic filling ratio.
♦Right hand diagram shows available molding zone by mold clamping pressure and section thickness. It was proven by this research. Utilization of injection compression molding ensures availability of thin section molding as well as substantial reduction of mold clamping pressure.
♦This is new ripple effect of our technology which was not recognized in the beginning.
