Question by AarDVark: Best Thermoplastic Design Book?
I’m studying in mechanical engineering and i’m really interested in plastic injection design. I don’t know much about it so i’m trying to find documentation. Right now, the best book i found is “The Complete Part Design Handbook – For Injection Molding of Thermoplastics” , it explains the difference between multiple polymers, what to do and not to do when dimensioning a plastic part, flexion torsion etc formulas.

Does someone has any suggestions ? Thanks!

Bayer Plastics Division has a free injection molding design guide in PDF format. You’ll have to create an account and log in, but here is a link to begin:

The Prototype Injection Molding and Injection Molds Services is a new webpage that was just added to the new Rapid Prototyping Information Website that has just been released. This new Prototype Injection Molding Process webpage has all of the information you need to know on Injection Prototyping and Thermoplastic Injection Molding and the main information you need to know on Prototype Injection Molding. You can visit this Thermoplastic Injection Molding Services webpage at: http://www.prototypezone.com/plastic-injection-molding/

Here is an excerpt from the new Thermoplastic Injection Molding and Molds webpage:

“Rapid Prototyping is the process of automated manufacturing of physical components using solid freeform fabrication. They are used in a wide range of applications, everything from medical to fine art. Rapid Prototyping machine works by taking virtual models from software and then converting it into extremely thin, horizontal cross-sections and then goes onto create each of the cross-section in physical space in a cyclic manner until the model is completed. Rapid Prototyping is a WYSIWYG process in which the virtual model bears identical resemblance to the finished physical model. Additional fabrications allows the machine to lay down layers of sheet, liquid or powder material and build up a series of cross-sections These layers are finally automatically fused together to render the final product.

The main advantage of rapid prototyping is the ability to create any shape no matter how complex the geometry is. The commonly used data interface between the machine and the software is the STL format. It works by approximating the geometry of a part using triangular facets, smaller the facets higher will be the surface quality. The word “rapid” is used relative top conventional methods which take days to construct a model depending upon its complexity. Rapid prototyping can create the model within a few hours, though it is highly dependent of the type of machines and the size of the model. There have been several new technologies available for rapid prototyping including Fused Deposition Modeling, Selective laser sintering, 3D printing, and Electron Beam Melting.”
