Have a Manufacturing Question? Ask Dean.


Q: We fabricate this circuit board in-house as part of an electronic musical instrument. Any suggestions on how we could decrease its cost?

Q: A vendor injection molds this part for us. The material is high-density polyethylene. Our problem is that almost every part has a horizontal line through it. What is the cause of this line and how could it have been prevented? The line is visible to the customer because the part is on the outside of our product.

Q: I am the manager of a small (15-employee) company. Our product requires manual assembly, which is both slow and expensive. Is there a way to improve the productivity of this operation?

Q: We are a small business and make these parts in-house using an injection molding machine. The material is Nylon 6-6. Sometimes our parts contain microscopic bubbles and/or streaks. Why?
