Basically the die is a block of metal containing an internal flow channel that can be divided into three parts. Sample pages christian hopmann walter michaeli extrusion dies for plastics and rubber design and engineering computations book isbn. Ascending profile temperatures that rise from the rear to the die. Daniel cykana has dedicated his 40 year career to profile extrusion.

Co sheboygan falls wisconsin for 32 years specializing in die and product design and processing. Co sheboygan falls wis for the past 32 years specializing in die and product design and processing. A cold die will restrict flow where as a too hot die will affect dimensions. Temperature profiles vary greatly and include.

He has worked in the advanced technology group of bemis mfg. When optimum temperatures are reached it is known as the temperature profile. Straight profile a temperature profile with all the same temperatures. The adapter section that connects with the output channel of the extruder 2.

Multiple mechanisms affect the size and shape changes in the extruded product and these can be controlled by die design. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part. Die design is basically a procedure where the internal die configuration is shaped to deliver polymer from the entrance to the exit with the same pressure drop. Pdf on jan 1 2006 milivoje m.

Die design for plastic extrusion part 2 admin 1 mar 06 2003 p art 1 of this article pm a nov dec. Daniel cykana has dedicated his 40 year career to profile extrusion. Kostic and others published design of extrusion dies find read and cite all the research you need on researchgate. Die design criteria the die is the assembly located at the end of an extruder which contains an orifice used to shape a plastics melt figure 1.

That provides a balanced flow where all of the polymer is exiting at the same velocity and closely duplicates the shape of the die orifice. Extrusion process plastic profile extrusion is a molding method in which plastic resin is continuously melted pushed through a die with the desired cross section a profile and then pulled through a water bath until fully cooled.
