Screen Mold Design Follow:
A. Part cover is critical, need texture on the A type surface as
require; also no flash, no gate, no welding line, no other cover
issues on the critical surface;
B. Bottom holes has critical function, W x L only has +/-0.05 mm
tolerance even up to 50 mm size;
C. Parting line has critical, no flash and need seal off light, so
deflection as flatness as 0.4 mm for part size as L x W=336 *182.3
mm. very hard to meet as part construction has many holes;
D. Color must meet client's color match requirement" D", details as
"E" should with in 0.5 with any inspection method, A, B, L should
within 0.7 with any inspection method.
Part constrution Review;
1. Part thickness as major as 2.3 mm, material is PC+ABS as Kingfa
2. Part construction has many buttom holes, that will cost so many
welding line on the cover;
3. Parting line has chamfer, that will be hard for gate setting;
4. Also will very hard to filling balance because we have to fill
from one side.
Mold Flow Analysis:
A. Fill time checking, two gate V. S three gate proposal.
B. VP compare.
