Understanding Metal and how it reacts with plastic during the molding process is a mutually supporting piece of information that can dictate your final molding cost. Its importance in setting cycle times and the end shape of your product is a vital part of your success in terms of quality and cost as it determines the rate of energy dissipation from the plastics into the cooling channels.
But not only do we need to look at it thermal conductivity properties we must look at its ability to with stand pressure and wear. If we use material that wears out prematurely the mold will have to be replaced which can be very cost prohibitive.
By using the menu buttons we have listed out a few common materials we have found that work well. Some are better than others in certain areas. So you will need to review the trade offs…Sorry there are no perfect choices just good trade offs that need to be reviewed by your team.
