Plastic Profile Design – Uniform Wall

When designing a Plastic Profile for Extrusion, it’s always a “best practice” to incorporate uniform wall thickness throughout the entire part. Dies are designed to allow the molten plastic to flow through them and to set up the shape and “lock it” in place upon cooling. With an uneven wall thickness, the speed of the Plastic in thick section vs a thin section will be different. This will make it more difficult to “balance the die” in getting the part to meet the print. Of course some designs may require different wall thicknesses and that can also be achieved with the proper die design. Here at Keller, we use computer modeling to design the die by matching it to the material viscosity.
