Reddit mentions: The best plastic processing books

>My challenge or I suppose my question would be what material I would use to manufacture something like that (like once I have a mold).


Material must be selected before the tool is made because the material properties drive the tool design (shrinkage rates, viscosity etc).

There are thousands of options for injection mouldable plastics so you'll need some requirements to narrow down your options.

Plastic Part Design for Injection Molding: An Introduction By Robert Malloy is a great intro to IM part design.


Check second hand book sites for cheaper used copies (Abebooks.com is good).

There are free design guide pdfs online (of varying quality...) which give a decent intro but are usually tens of pages so obviously don't have the detail a decent books will. The guides by Bayer and Dupont are the best imo.

As someone in a similar situation, I'd recommend these two books. They're what were were taught with when I was in college for my Plastics Engineering degree (Bachelors at Umass Lowell). I've had both of the authors as professors.

I'd also recommend this book by Professor Kazmer: Injection Mold Design Engineering if you want to design the mold of a injection molded part. DON"T OVERLOOK THIS. A lot of times our professors were explaining how they'd have to help companies who designed a good part that couldn't physically be molded.

The previous book mentioned by Professor Malloy: Plastic Part Design for Injection Molding 2E: An Introduction is for actually designing the part.

Also, make sure that you get a book on polymer material science. Learn about the different types of plastics, how they handle, ect.

Start with reading some simpler PDFs from resin suppliers like this one.

A big thing to consider is also this: Does the company

• Design the part?
  
• Manufacture the part?
  
• Design or make it's own molds?

is this the one you are talking about ?

as someone with little background in engineering, physics, pchem, i am looking for a book that appeals to the organic chemist.

here is another option i found, with a good amazon rating

http://www.amazon.com/Polymer-Chemistry-Introduction-Malcolm-Stevens/dp/0195124448/ref=zg_bs_16052541_6

have you seen this book? it seems like it might fit my organic background better, and people say it has good exercise problems

Although it's not a course but I recommend picking up this book, Plastics Part Design for Injection Molding by Robert A. Malloy. Professor Malloy recently retired but he was the head of the Plastics Engineering at University of Massachusetts Lowell. The book is really great for design engineers like yourself. Buy it and you will not regret it.

For plastic injection molding, this book was a good start for me. The issue is, you can take a feature (e.g. snaps) and write volumes on design and application - don't take one book/source to be the only reference.

The various resin suppliers also publish DFM literature that can be useful and worth reading.

Dupont Assembly Techniques -- more articles here

BASF on snaps -- more from BASF

And, as silly as it is... Occasionally protomold will publish a useful nugget of practical information.

Thank you for your time and for your kind answer!

As for the material, I've found this this and obviously the good old Kalpakjjian

Sadly during my MSc we gave just a brief glance to this type of manufacturing so I'm looking for some ways to "upgrade" my knowledge about the subject.

As for the part related I'm not talking about the HR side of the question but more about the work distribution process. Could you tell me what really helped you in this?

ps You are absolutely right about the CAM videos on YT there're many fantastic walkthrough that I'm following at the moment

I bought this book a few years ago when I needed to start designing more complex injection molded parts. I still reference it. Great easy to read book. https://www.amazon.com/Plastic-Part-Design-Injection-Molding/dp/1569904367

Engineering Plastics Handbook

Injection Molding: Process Design and Applications

Though if you didn't already know, there are tons of books and articles and training resources available that you were not aware of as a student. Ask your colleagues or your supervisor if they have particular recommendations. A big part of your career is going to be finding this information yourself.

Good Luck!

Plastic Part Design for Injection Molding is probably one of the best books out there on the design of plastic parts. Might also be worth looking into a course or book for injection mold tool design since understanding, draft, parting lines, shutoff, ejection, lifters, gates & runners and all other stuff that contribute to the limitations of plastic part design.

I have the older version of this book, which I quite like:

https://www.amazon.com/Plastic-Part-Design-Injection-Molding/dp/1569904367/ref=sr_1_1?s=books&ie=UTF8&qid=1488321538&sr=1-1&keywords=plastic+part+design+for+injection+molding

I imagine this one has some nice updates.

Here is a good snap fit guide:

Also we have this book in our library at work:
Plastic Part Design for Injection Molding 2E: An Introduction https://www.amazon.com/dp/1569904367/ref=cm_sw_r_cp_apa_AjduzbRTN0ZFN

This is a really good one:

There are a few injection molding guides on Amazon. Here’s one that I found. Search on Amazon and other used book sites. I bet you can find something for $30.

There's still nothing quite like owning a print copy. To add to that, I would love to have a hard copy of Ullman's Encyclopedia of Industrial Chemistry.

Amazon seems to have it for the low price of $10260 |:

http://www.amazon.com/Ullmanns-Encyclopedia-Industrial-Chemistry-Wiley-VCH/dp/3527329439

I will give you the OP is probably full of BS, but I found an example on amazon in under 30 seconds.

Could happen

As an engineering manager for a contract manufacturing firm that specializes in Plastic Injection molding, if you're looking at "free" online resources, the "best" I've run across is [The GE Plastic Design Guide](http://www.manterra.com/GE_Design_Guide.pdf)

For non-free, the "gold standard" is [Malloy](https://www.amazon.com/Plastic-Part-Design-Injection-Molding/dp/1569904367)

I believe it was "Understanding Extrusion" by C. Rauwendaal. It's about 200 pages and written so technicians can understand it. He also wrote a textbook called "Polymer Extrusion" which contains more of the technical explanations and equations.

Understanding Extrusion
https://www.amazon.com/dp/1569904537/ref=cm_sw_r_cp_apa_6.ciAb0Q97E78

Polymer Extrusion https://www.amazon.com/dp/1569905169/ref=cm_sw_r_cp_apa_mbdiAbBWAEA7S

Polymer Extrusion by Chris Rauwendaal goes really in depth about all aspects of extrusion, including screw design.
