Does this part need an ejector pin or an ejector bar? Can we add an ejector blade?
4. We are planning to make a barrel (or a pin) for the post position of this product. （Can we add an ejector blade?
4.
Can we add ejector sleeves or ejector pins in the boss of this part?
5. The product can't be molded out in this position, so we are going to make a row position, and there will be a parting line on this side, do you accept it?
There's an undercut at this position and it needs a slider. It will also have a parting line on
this side, is that OK?
6. We're going to do a slant top or inline position inside the product, is that OK?
We will make the lifter and (inner) slider in this position, will that be a problem?
7. The 2D product drawing you provided is inconsistent with the 3D product drawing.
The 2D and 3D drawing you provided is not the same, can you tell me which one is correct?
8. The 3D drawing you provided has no mold angle in some places, the glue position is too thick in some places, the glue position is too pu in some places.
Can we modify it ourselves? After the modification, we will give you the confirmation.
There is no draft angle in the 3D drawing, some materials are too thick, and some place are too
thin. Can we modify this part by ourselves? can we modify this part by ourselves? We will send the drawing to you for you to check after
we modify it.
9. According to the shrinkage rate of 5 thousandths provided by you, the dimensions of this mold have already achieved the requirements of the mold drawing. However, the molded product does not conform to your
product drawing.
Can you please confirm that the shrinkage rate of your material is correct?
According to the shrinkage one over two hundred, the mold has been done in the right dimension, but
the part falls short to your part drawing, are you sure the shrinkage is right?
According to the shrinkage one over two hundred, the mold has been done in the right dimension, but
the part falls short to your part drawing, are you sure the shrinkage is right?
10．
This position is too small and will make the steel material here too thin, can we widen it here?
11. The space between the slanting top and the back of the column is too small, and the slanting top will interfere with the column when it is in motion, can we move the position of the column?
11. The space between the pitched roof and the columns behind it is too small.
The angular lifter interferes with the boss during ejection. Please consider changing the position
of the boss.
12. The glue thickness of this rib position is too pu.
12. This rib is too thick, and the height is too high, so it is difficult to fill this rib during ejection, can you increase the thickness of this rib?
The rib here is too thin and on the high side, so it will be difficult to fill here when we do the
injection, can you inrcease the thickness of this rib?
13. Do you want to raise/lower the height of this rib? We will deepen the position with copper male discharge. But there are two ways to do
the reduction of the position of the glue, 1, do the inlay; 2, weld; because the bottom of the inlay has water transportation, we simply do the weld treatment, you can accept?
Will you increase/decrease the material on this rib? We will use EDM if you add material, but there
are two options if you choose to decrease. 1.Make inserts; 2.Welding, because there is water in the
bottom of the insert, is that OK?
14. The bottom of the rib in this sample is burnt because of poor venting, we can add an insert in the middle of the rib.
14. The bottom of the fascia is burnt because of poor venting.
This sample has been burned in the bottom because the venting is not good, we can add an insert in
the middle of the rib.
15. It will take about 5-6 days to redo the insert.
15. It takes about 5-6 days to remake the insert.
It will take about 5 or 6 days to redo the insert, is that OK?
16. This side of the product we have already done the tanning treatment, if we need to add glue, this side we need to re-send out the tanning. It may take a few days
So we directly replace the pattern you asked for with the spark pattern of the copper male discharge, is that OK with you?
We have already done the tanning on this side of the product.
We have made the texture on this side, if we add material, it will take some days to remake the
texture by out-resourcing, so we suggest using the texture by EDM instead, is that OK?
17. Is the mold made with metric/imperial fittings? Is that OK?
17. Is the mold in metric/imperial?

23. It's time for lunch, can we continue this afternoon?
It is time to have lunch, let's discuss this project later this afternoon?
24. and the slide block interferes with the undercut hook please add material to fill until the slide block can slide smoothly
(The undercut area interferes with the slide block and needs to be filled with material to help the
slider move smoothly.)
25. The thickness added is too The thickness added is too thick.)
26. The thickening area is too wide.)
27. The split line of slide block or the area of slide.)
29. It is hard to fill this area due to the sharp feature.)
30. The steel in this area is too thin, not strong enough and does not cool down easily
( The strength of this area is too weak and it is hard to cool because the steel is too thin.)
31. Cylindrical features should have a half-circle that can not be removed from the slider, so as to avoid sticking to the slider, resulting in pulling the white, pulling off
(We avoid designing the semicircle of the cylinder on the slide block because it will be pulled
apart or cause drag marks.)
32. The part will be cut to the finished product when the slanting pin is made
(The part will be cut to the finished product when it is made
(The part will be damaged if we make the lifter in this area.)
33. This is a critical surface where we cannot add additional material.)
(This is a critical surface where we cannot add additional material.)
34. This material level is too thick, there will be shrinkage, we suggest reducing some wall thickness to improve it.)
(Because of the shrinkage of the thickness, we suggest reducing some wall thickness to improve it.)
35. Is this surface a critical surface or not. Also, confirm whether it is acceptable to
"(Please confirm whether it is a critical surface or not. Also, confirm whether it is acceptable to
have a slide
split line if we have a slide in this area. )
36. There is a barb here, can we reduce material to the area so that the male and female molds break against each other, without doing a slide and a skewed pin
"(Please confirm whether we can reduce material to the area where we have an undercut as indicated
to have shut off
on cavity side. No slide block and lifter No slide block and lifter will be made.)
37. Please confirm the issues of Parting line, Gate position...Etc. as soon as possible as possible. .Etc. as soon as possible; otherwise,
the lead-time will be extended.)
38. Is there any special requirement for this surface, can there be a thimble print
(Please confirm whether it is a critical surface or not and if we can have E.J. pin marks on it.)
39. P.L surface open here, there will be sharp corners and cuts on the mold, it will have an effect on the mold life
(There are sharp edges if we set the There are sharp edges if we set the parting line here, It will reduce the tool life)
40. We suggest enlarging the draft angle to help release the tool.)
41. There are two drawbacks if GATE is used here: 1. The trimmed part of GATE can be seen when the lid is open; 2. The two tilt pins are on the same side and the ejection is not
well balanced.
(There are two problems if the gate is to be designed in this area:
a). It is easy to see the gate mark when you open the cap.
b). The ejectors are unbalanced when two lifters are on the same side)
42. If GATE is done here. The trimmed part of the GATE is not visible when the lid is open
(The gate mark is not visible if the gate position is designed like this.)
43. If the GATE has to be done in the position you specified, it might as well be done on this side, which would can also minimize the shrinkage of this location
"(If you insist that the gate position has to be like the original design, then we would further
recommend to have
it to the area indicated so it can avoid a shrink problem in this area.)"
44. If you make a submerged thimble here at GATE, there will be punch marks on the exterior surface behind it, and the finished product will be black, which will be the most noticeable
(If the design of Gate, then the back surface of the part will have
serious flow marks due to the black color.)
22. P.L open here is unreasonable, the mold processing difficulties, P.L should be replaced by a new one.
This area is not suitable to have a Parting line because the tool will become more complicated;
therefore,
we recommend to have the Parting line as shown in the drawing
"(This area is not suitable to have a Parting line because the tool will become more complicated;
therefore,
we recommend to have the Parting line as indicated.)"
"
45. There is a high chance of the product sticking on cavity; therefore, it is possible to add a hook on cavity, pulling thimble or keep the E.D.M pattern on cavity, so that the finished product will be left on one side of the cavity when the mold is opened
"(There is possible sticking on cavity; therefore, please confirm whether it can make undercuts,
snatch pins
or leave coarse E.D.M. on the core to snatch the part on)"
46. Here the material thickness section difference is very big and there will be stress lines on the surface of the finished product, is it acceptable
(Please confirm whether it is acceptable to have stress lines on the surface because the thickness
is not acceptable to have stress lines on the surface because the thickness
is not acceptable to have stress lines on the surface. thickness
is not equal.)
47. Please advise where the critical surface is. Please also provide us a 2D drawing with critical
(Please also provide us a 2D drawing with critical
) Please also provide us a 2D drawing with critical
dimensions. )
48. Please note the red highlights because those areas have problems. )
49. The finished design has problems here, we would suggest modifying it as shown below
(We would suggest using the attached part design as the current design has problems.)
50. This is changed to a spherical notch. (We suggest modifying it as a globe recess.)
51. Half of the cylindrical feature should not be detachable in the slider to prevent it from pulling off (this issue is the same as no.8)
52. Here the big slider goes on the small slider, and the small slider has to back off first, and the big slider has to do the delay <
(The inside small slide block will recede first and the parent slide block have to postpone
sliding.)
53. The slide pins have to be pumped with hydraulic cylinders to ensure the sequence of opening and closing of the mold
.
(The slide pins will use an oil cylinder to assure that the process is in proper order.)
54. There is an assembly on this surface, and if you add material, the assembly will hold up, as shown in the picture
"(We cannot add material to this surface because it will interrupt
"
"). material to this surface because it will intervene between the two parts when it is
assembled.
Please see the sketch attached.)"
55. To descend the surface of the lifter in order to thicken the part.)
56. One half side will have the lifter and the other half will be natural. lifter and the other half will be
solid/natural.)
57. Here two bosses are overlapping with undercut therefore it can not be made natural, it has to be made SLIDE
" (These two bosses are overlapping with These two bosses are overlapping with undercut therefore it can not be made as solid. We
suggest making it with a slide block.)"
58. This area needs force ejection.)
59. Here will be a double ejection for forward and receding.)
60. Please confirm whether it is acceptable that there will be a line of clamping in this area. Please confirm whether it is acceptable that there will be a
split line here.)
61. This area where there is 1 degree of shut off
(Please confirm whether it is ok to have mismatch to the area where there is 1 degree of shut off
(Here will be a double ejection for forward and receding.)
60. is 1 degree of shut off
in Core / Cavity side.)
62. Can this dimension be enlarged (Please confirm whether we can enlarge this dimension.)
63. Add a groove here, the film will pop up better. It will affect the elastic of the film better if we add a recess. See how it will affect the
assembly parts,
and then make your own adjustments.
and then make your decision.)"
64. There is an undercut here, we suggest cutting out the indicated part as it highlighted to avoid an
(There is an undercut here, we suggest cutting out the indicated There is an undercut here, we suggest cutting out the indicated part as it highlighted to avoid an
undercut.)
65. The gate (sub gate) needs to be trimmed evenly after being molded.)
66.
66. This area of the undercut needs to be ejected vertically, then taken out manually.)
67. There are sliders on both sides.
(The gate is not suitable in this area becuase there are two sliding blocks sealing off this area.)
68. Add a rotating GATE here to adjust the quality of the finished product when it is shot
(We would suggest placing a rotating GATE here to adjust the quality of the finished product when it is shot.)
(We would recommend placing a rotating GATE here.
(We would suggest placing a runner shut-off insert to adjust the volume of part filling.)
69. This undercut will be force ejected out of the mold on the sliding blocks, can the undercut be reduced to 0.6
(This undercut will be force ejected out of the mold on the sliding blocks.)
(This undercut will be force ejected out of the mold on the sliding blocks.)

original draft
71. This boss will shrink because it is a solid boss.)
72. This surface needs to be textured or not, what is the texture specification, and what is the minimum draw angle
(Please confirm whether this surface needs to be textured or not. . Please advise texture specs.
Also, what's the min. draft. )
73. Please confirm whether this surface needs to be polished and stuck on a sticker.)
74. The red highlighted area has a problem of a small draft angle. We suggest enlarging the
draft to avoid casuing drag marks on the part.)
75. This RIB is too thin. This rib can not be filled properly because it is too thin.)
76. This rib will have a shrink problem because it is too thick.)
77. It is difficult to mold the chamfered hook here, so it is recommended that we don't do the chamfered hook first, and then do the secondary processing after molding. p>
(There are problems with this current design, we recommend doing this undercut as an alternative
but there will be additional costs.)
78. p>78. The base of all bosses require a crater to avoid shrinkage.)
