With the goal of further increasing the machine’s productivity, Tahara has developed heat transfer and cooling simulation software to shorten cooling time.
It evaluates all the cooling factors in the process of
1) extruding parisons,
2) blowing air into bottles,
3) cooling down bottles by running cooling water through the mold,
4) circulating air inside bottles, and
5) cooling down bottles with post-cooling devices after removing them from the mold.
Tahara performs 3D simulation for analysis when considering the design of a head and the extruder screw that is responsible for resin flow. This simulation and analysis is used to:
-Design resin flow paths on the kneading and mixing parts of extruder screws
-Design head mandrels which distribute the flow volume evenly
-Detect and solve the cause of sears by tracking the path line
-Simulate and determine the cause of resin layer disorder in multi-layer heads
Head Design and Fabrication
Tahara’s leading-edge technology and its advanced machining facility enable us to fabricate head components with high-precision. We set high standards on the surface roughness of the flow path walls and the concentricity of each mandrel in order to produce high quality parisons.
