Fred Phillips of SIGMA Plastic Services discusses SIGMASOFT® generates simulations in a fundamentally different way than traditional simulation tools. When process simulation is coupled with all of the mold components, the entire injection mold and process is simulated, rather than assumed. This allows users to make accurate and confident decisions about tooling designs and process parameters. These capabilities will be shown through a powerpoint presentation and software demonstration. Fred Phillips with SIGMA Plastic Services, Inc. offers a series of webinars to present SIGMASOFT®: The Next Generation of Injection Molding Polymer Simulation. This webinar series will cover a variety of SIGMASOFT® benefits and capabilities. If injection molded plastic or rubber parts are critical to the success of your business, you will benefit from attending these webinars. SIGMASOFT® is utilized by Part Designers, Mold Designers, Project Engineers, Process Engineers, Quality Engineers, CAE/FEA Analysts, R&D Teams, Plastics Business Owners, Engineering Management and Production Management. When it comes to making the right design, tooling, and process decisions, the accuracy of simulation makes all the difference. The reason SIGMASOFT® simulations are so accurate is rooted in its history. The core simulation physics and programming in SIGMASOFT® were developed by the same company that makes MAGMASOFT® – the foundry and die casting industry’s de facto standard for metal casting …

Question by Nick S: manufacturing process of acrylic guitar? ?
Hi, I’m currently doing a piece design technology work in which i have to outline the main process in making an acrylic guitar base. However i am unable to find any information which is clear and easy to understand, basically can anyone tell me how it would be done? eg. blow molding or injection molding.
Thanks.

I’m not sure it’s the most practical method for making an acrylic guitar body but here’s one way to do it that wouldn’t require an expensive mold. You would start with a slab of acrylic ordered in the desired thickness of the body. The profile of the body would then be rough cut slightly oversize on the band saw. Next the profile and the internal cavities would be cut to shape by a template guided router or a CNC milling machine. Finally the machined edges would need to be sanded smooth and polished either mechanically and or chemically until the edges become clear. To find out for sure how it’s done you should contact Ampeg, a company best known for it’s guitar amplifiers. Back in the sixties Ampeg, in collaboration with a guy named Dan Armstrong produced a guitar and a bass that had bodies made out of Plexiglass. If anyone knows how it’s done these guys do. Best of all the company is still in business and has recently reissued these plexiglass guitars. Give them a call. Hopefully they will help you out. Good luck.

Question by justbecause: Manufacturing process?
What is the manufacturing process of plastic gears – in particular, nylon gears. I’ve read somewhere that its injection molding and in other articles i’ve read its milling/hobbing. Anyone know what is correct? Thank you in advance – much appreciated!

Question by Josh S: what are some manufacturing process for HDPE?
I’ve been searching Google all day now and i can not find out some ways to manipulate HDPE into becoming a product.

I do have a feeling that it is probably blow Molding or injection Molding.
