Have a Manufacturing Question? Ask Dean.
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.
