Abstract
The present invention relates to ducts, pipes, and other complex convoluted parts (e.g., automotive parts) formed via 3D-blow molding, and to methods for making such ducts, pipes, and other complex convoluted parts out of a plastic material. In one embodiment, the present invention relates to exhaust ducts, exhaust pipes, and other complex convoluted exhaust parts formed via 3D-blow molding, and to methods for making such automotive and/or vehicular exhaust parts out of a plastic material.
Claims20
An exhaust system comprising:
- at least one pipe;
- and
- at least one muffler housing,
- wherein the at least one pipe and the at least one muffler housing are joined together and wherein the at least one pipe and the at least one muffler are formed from at least one plastic and/or polymeric compound.
1 more element
An exhaust system comprising:
- a first pipe;
- at least one muffler housing, wherein the muffle housing contains therein at least one honeycomb structure, the at least one honeycomb structure aiding in noise reduction, and wherein the at least one muffler housing is operatively connected to the first pipe;
- and
- a second pipe, wherein the second pipe is operatively connected to the at least one muffler housing such that the combination of the first pipe, the at least one muffler housing and the second pipe form an exhaust system,
- wherein the first and second pipes, and the at least one muffler housing are formed from at least one plastic and/or polymeric compound.
2 more elements
A method for making an exhaust system comprising the step of:
- using 3D-blow molding process to form an exhaust system from a suitable plastic and/or polymeric compound.
