Abstract
A method of producing hollow plastic components, such as for air conduction in internal combustion engines, in which two or more molded or hollow body members are manufactured using injection molding technology, are thereupon brought together and are joined together using plastic welding technology.
Claims15
A method of producing hollow plastic components in which two subcomponents are injection molded and are thereafter brought together to be joined by a plastic weld, the method comprising:
- molding two subcomponents using a multi-component injection molding technique, each of the two subcomponents having two portions each made from a different material;
- simultaneously melting the two portions of the two subcomponents to melting temperature prescribed for each of the two portions, the melting occurring at joining portions of each of the two subcomponents;
- bringing the joining portions of the two subcomponents together;
- applying a pressure between the joining portions of the two subcomponents.
A method of producing a hollow plastic component, the method comprising:
- molding a first subcomponent having a first seam that includes a first section made of a first material and a second section made of a second material, the first material having a first melting temperature and the second material having a second melting temperature different than the first melting temperature;
- molding a second subcomponent having a second seam that includes a third section comprising the first material and that is configured to mate with the first section and a fourth section comprising the second material and that is configured to mate with the second section;
- heating the first and third section to the first melting temperature;
- heating the second and fourth section to the second melting temperature;
- positioning the first section in contact with the third section and positioning the second section in contact with the fourth section;
- and
- applying pressure between the first and third section and between the second and fourth section to join the first component to the second component.
