Thanks again everyone for taking the time to reply. Really appreciate all the activity in the thread. Material Properties from Matweb: http://www.matweb.com/search/DataSheet.aspx?MatGUID=eba8ff43155542e0af2d8e731863c589&ckck=1...

Thanks for all the replies everyone. 3DDave That actually makes a lot of sense, using some rough approximations, I predict that the uneven geometry of the card would result in ~45% stress riser due to an increase in the distance from the neutral axis. Assuming I is of a rectangle 60mm x 2.2mm...

Below is an image of the sample cards that were used. Link to the materials in question: POM (aka Delrin): http://plastics.ulprospector.com/datasheet/E94861/Delrin-500P-BK602 PBT 30GF: http://plastics.ulprospector.com/datasheet/E4726/VALOX-420SE0-Resin Stress Strain for Delrin 100, a similar...

I was doing some informal "testing" of two material samples. They were material sample cards from protolabs, one of Delrin homopolyer and one of Valox 420 PBT with 30% glass fill. Each card is about 3" x 6" and 1/8" thick. The Delrin has a rated yield strength of 71MPa on prospector, and some...

They are sldprt files, the default solidworks format. Which file type would be more universal? And I have talked to my company they are fine with it.

Thanks! http://files.engineering.com/getfile.aspx?folder=8e60b714-ef9d-4b39-b056-f529100a5fe6&file=Thread_Cap_-_Inside.sldprt http://files.engineering.com/getfile.aspx?folder=d6abd5ff-b343-482b-ac69-f89db13f6f2b&file=Threaded_Cap_-_Outside.sldprt These are the part files for the Battery Cap

Also, if someone could briefly tell me how I can A) edit posts and B) attach more than one file I can supply the part files for the batter cap if anyone wants them.

Greetings everyone! I am a junior mechanical design engineer charged with designing an injection moulded enclosure for an electronics device designed for submergence up to 300m. Specifically I am looking for some feedback regarding my design for the battery cap. -The battery cap will act as...

Thanks for the advise everyone. I broke up the sketch into 6 2D sketches, and the design is now far more robust and easier to edit. Thanks everyone!

I am attempting to design the body an injection moulded wrist worn watch. In order to increase the aesthetics of the product, I have tried using a 3D sketch to create an three dimensional outline of the unit to make its appearance less blocky. I then use Boundary Surfaces and Surface Knit to...

Thanks for all the input everyone! So I changed the drilling process to drilling an undersized hole and then milling out to the proper diameter. This resulted in a greatly improved surface finish, so hopefully there will be less micro cracks to propagate. I also changed the fasteners to machine...

I am worried about flame polishing inducing stress in the component. Taken from the manufacturers fabrication guide: "The most important factor to consider when drilling Lexan sheet products is the heat generated during the actual process. In order to produce a clean, well-finished hole that is...

I am having issues with drilled through holes in lexan forming radial cracks when compressed by a fastener. I am trying to diagnose the cause of the crack and am looking for advise! First time poster. No cutting fluid, cleaning products or adhesives are applied to the lexan during the machining...
