Conventional blow molding of 3D tubular shapes, such as filler pipes, air ducts, tubes used in household appliances, etc., can lead to welding seams at the pinch areas creating excessive flash that in some cases can weigh multiple times the weight of the finished part. Moreover, long pinch areas need high clamping forces.
Kautex 3D technologies offer minimum flash production for significant savings in material, energy, cycle times and, last but not least, in capital spending.
In 3D blow molding, a parison sized to the article diameter is manipulated directly into the blow mold, thus avoiding pinch areas and welding seams on either side of the article and reducing material usage.
Advantages of 3D Technology
- Higher part quality due to the elimination of welding seams, resulting in:
o Better wall thickness distribution
o No decrease in mechanical properties as material accumulation and/or notches at welding seams are avoided
o Use of materials which do not bond at the pinch areas
o Processing of short glass fiber reinforced materials
o Lower regrind content reducing the risk of degrading thermally sensitive materials and break down of fibers in reinforced materials
- Lower flash weight, resulting in:
o Lower capital cost because of the use of smaller extruders, lower clamping forces, simple deflashing , smaller peripheral equipment
o Lower operating costs due to the reduced amount of material being processed lowering the power usage of drive motors and heating systems
