October Tip - Seeing is believing

This month's Design Tip is to take advantage of our offer to send you your very own Protomold Rapid Injection Molding Sample Part that illustrates a number of the tips we have published over the past year.

We've purposely designed and manufactured these parts to illustrate example issues you may run into like thin sections that won't fill, thick ribs, bosses or other features that cause backside sinking, and the appearance of knit lines downstream from through-holes.

It also includes some example design suggestions such as how to tie bosses to walls, creating undercuts that can be made without side actions, providing sufficient draft for sliding shutoff surfaces and how to strengthen bosses without causing sink. And last but not least, the sample part illustrates the six standard surface finishes that are available with our Rapid Injection Molding service.

Just send an email to marketing@protomold.com with your name and mailing address and we will get one out to you along with an informative "key" describing the importance of all the features on the part.

As always, you can visit the Protomold Design Guide for helpful Rapid Injection Molding design information.

September Designer Survey Results:

We asked "How much do you know about resins?" The responses of the approximately 250 people that responded are graphed in the pie chart. It looks like there are enough novices to justify a review of a relevant book in this area within our Winter '04 Rapid Injection Molding Journal. We'll start looking for something we can recommend to you.
