The Troubleshooter

摘要

The part I picked this month is unusual enough that I thought it would be worth sharing.It's a box with two living hinges,being fed through a three-plate runner.The material is a rubber-modified polystyrene- probably one of the K-resin products from Chevron Phillips.(Even if it's not K-resin,many molders still use that name because that's what they're used to calling a material like this.)
