You should not shop for a molding machine until you have an actual use for one.
If you know exactly what you will be molding, and what quantities you will be making, then choosing a molding machine properly sized for your need will be easier and more cost advantageous.

I have been in your position before...
Get a hold of a couple of McMaster Carr catalogues...one for you, and maybe a couple others that you can use as 'handouts' if there seems to be anybody that 'has a need to know'.
Anyway, the McMaster Carr catalogues have pretty good descriptions of the...
Maybe I'm a little late to the party here, and I have not read thru all the posts, but something just struck me looking at the image at the top of this thread - the image of the 'cup' with the external female bayonet mount undercuts. My idea might get in the way of any aeshtetic you need for the...
I've worked with speakers in which thee was a (smaller) metal (.125 thick aluminum?) panel in which shallow radiused ribs were pressed into the one panel itself to add stiffness - some toling sharges were involved, but these ribs didn't involve any extra pieces that needed to be welded into...
I'm not sure why your boss is resisting this. I have worked with both ways of ballooning and prefer putting quantities in balloons, but yes it may amount to personal preference. I don't recall any specific standard. but when I have used split balloons in the machine tool and semiconducter...
Question 1...anyone design toys - YUP...about 20 years ago
Question 2...madenning??....My position was 'Mechanical Designer'. Back then, by the time a mechanical designer was called into play, the basic geometry of the toy was pretty well defined, as it was pretty well developed before it...
Maybe another way to help save the piece is to open up the tolerances on the dimensions locating the hole pattern...say from +/-.010 to +/-.06 as OutofSquare stated the sides don't mate with anything and then maybe the holes could possibly be counter-bored to open up clearance for the fasteners...
With all due respect to everyone here, I don't think anyone of the respondees has this right.
ANSI 14.5 may not have been specified on the drawing, and whilst ANSI Y14.5 could have been invoked to enable less rigid manufacturing methods, that doesn't mean that the specification for the hole...
Some of your responses thus far mention 'Cincinnati Milacron'....I live in the town that housed the grinding division of Cincinnati Milacron. Although I can't pinoint any centerless grinding info, this area seems to have been a hotbed of engineering technology with regard to grinding for the...
"Engineering Drawing and Graphic Technology" by French and Vierck was my text from 20 years ago. There is also a an older book 'Technical Drawing' by Giesecke, Mitchell, and Spencer that was very adequate way back when....
If you can get a recent edition of either of those, I'm sure they would...
A better description of the part along with dimensions may help. (with all due respect, seems to me ya can't get much cheaper than 'pigeon hole' boxes if constructed out of paper product, but tell us what you can about the part and we'll see if we've got any answers)
