Hello guys, well this is my first post. I wanted to ask you about problem related to injection molding machines producing the car's head-rests. the fact is the machine can't give us a good precision on the shape of the product by showing some unusual residus. We did try to clamp the cavity and core side of the mold but we didn't get a result. I'm looking for some smart solutions or some ideas who can guide me to improve the molding process precision and to identify the preventives treatments. Thank you.
