Fate, B-coverAssembly No Component

Sub assemblymaterial operation secondary operation assembly method

1 B-cover Pc/ABS+PTFE 5% IM no no

SuggestionWill the features along the B-cover sides cause any problems…?

risk for sink marks due to wall thickness of elements, 80% of main wall. MoldFlow needed to check final result.

draft to be modified due to up&way movement direction

1 B-cover Pc/ABS+PTFE 5% IM no no

SuggestionWill it be possible to do the undercut in the bottom of the B-cover due to shape of the cover and placement of the hook features…?OK Is there room enough for the slider which should make the undercut…?OK

Fate, B-coverAssembly No Component

Sub assemblymaterial operation secondary operation assembly method

1 B-cover Pc/ABS+PTFE 5% IM no no

SuggestionCover thickness is assumed to be 1mm – how do you feel about the strength of the cover…?

internal radius missing

gating position is critical to avoid weld lines in corners

FEM analyze needed to check final result

Material is assumed to be PC/ABS and maybe we’ll add 5% PTFE (Teflon) because it’s a slide-on battery cover.

We will check from raw material supplier effect of Teflon for impact strength

optional raw material, PA12

weld lines positions
