A product structure and mold performance review:
1, the assembly clearance is appropriate
2, the adequacy of fixed / reasonable
3, the slide distance is sufficient, the installation is convenient
4, the shell glue is too thick or too thin
5, whether there is excess or shortage of housing structure, make the mould complexity
6, screw pole forming is smooth, the supporting strength is in place
7, confirm the product line clamp
8, whether the smooth connection with corner
9, whether the top buckle a shovel rubber
10, sloping roof strength is enough or too wide, both sides are thin steel
11, whether the smooth lines or font molding
12, the existence of sharp corners forming die
13, plastic bits is uniform, whether there is a thin plastic forming
14, a small section of the existence of glue
15, in line with the direction of the mold the mold is inverted
16, the existence of the irrational structure of plastic buckle
17, the existence of thin steel plastic molding
18, the overall structure of the product is reasonable, whether caused by variant.
19, the product structure of the transition is smooth, whether to affect the appearance of the production
20, the appearance of the existence of sharp 9
21, into the gel point is whether enough thickness
22, the existence of a gel point
23, to promote the assembly relation are oriented
24, before and after insertion is a slope model
25, the appearance of the product whether there exists sharp blow hand.
26, the bottom shell is battery buckle slot
27, hot melt column height is enough
28, the board is empty avoiding a tail assembly
29, the product material fixed adequacy
