Anyone can help in medical molding?
I like to know the general guide for medical moldings and comment defects encountered in shop floor.
1. How do medical molding differ from normal moldings like consumer goods or automotive parts? Is there really any difference?
2. Common design challenges in medical moldings?
3.Common defects in medical moldings
4.General design guide for medical molding.
Please anyone can help on this topic! Thanks in advance.
Common design challenges are things like wall stocks that vary greatly, and parts that can survive sterilization by various methods and exposure to harsh chemicals in use.
In addition to the regular defects, one sees contamination issues, especially even microscopic quantities of other non-specified resins.
Design guides are similar to most plastics parts.
In lieu of a full blown tool design/text book, many of the compounders out there have very good design guides. Most of them are specific to the material being used, but will give you some good ideas on processing, tool design and material properties. I don't know if there is a design guide for medical parts per se. Unless you are specifically interested in injection molding in a clean room environment and/or very high tolerances, the principles of injection molding design and processing remain the same. The material will be the largest factor in tool design and processing.
