Ask the Engineer: Micro-Molding – Four Case Studies
The fifth thing we think everyone should know about micro-molding is more of a philosophy than it’s a process. Keep driving!
Ask the Engineer: Micro-Molding – Prototyping Challenges
We continue our discussion on the five key components of micro-molding, with a focus on Prototyping this week (read more articles on Micro-molding here). Here again is another potential barrier you may face when developing parts for micro-molding. Prototyping as you know is a regular part of any design process. There are also many different…
Ask the Engineer: Micro-Molding – Material Selection
Don’t let material selection keep you from your ideal part design. In some cases, it might just not be a problem at all.
Sticky Questions on Adhesives
“I am trying to understand the UV-curing process. How can I determine when an adhesive is fully cured? What are the critical parameters that I need to control in order to gain good consistency for the curing? Also, I was trying to cure some adhesive on a piece of stainless steel coupon. One small drop…
Ask The Engineer: Sticky Questions on Adhesives
What is the risk posed by uncured monomers, and what polymers can be used for a cover plate that can transmit sufficient UV or light to allow types of cures? This week’s Ask The Engineer answers these questions and more.
Ask The Engineer: Sticky Questions on Adhesives
Are there FDA required or recommended adhesives for constructing non-DEHP or non-phthalate PVC medical devices? Read this week’s Ask The Engineer to know more.
Spring Design in Product Development
If required in the product, the spring is probably the least expensive component of the assembly. However, if it does not function as intended or fails, it can become a warranty issue which can be quite expensive as far as repair, loss of sales and product reputation.
Specification Requirements to Ensure Regulatory Compliance
There has been a sharp increase in regulatory oversight in the medical device industry. If your manufacturing requirements aren’t specific enough, your contract manufacturer might unknowingly make a problematic substitution. Which requirements are most important for your product? This week’s Ask the Engineer addresses material types, critical features and measurement methods.
Reusable Medical Devices
Will FDA accept reprocessing instructions from a predicate device? What do proposed guidelines say about the requirement of multiple markers to properly demonstrate cleaning efficacy? This week’s Ask the Engineer covers some frequently asked questions on this topic.
Adhering Polyethylene to Various Substrates
Several questions are asked about light curing adhesives and are answered by Irene Boutin, Application Engineering Manager, Dymax Corporation
