| 摘要 |
The invention relates to a housing (1) of a radial flow compressor, comprising an intake pipe (4), a compressor duct (7) and an outlet pipe (5), wherein the housing comprises a housing body (basic construction) comprising at least an upper housing member (3) and a lower housing member (2) made of a fiber-reinforced thermoplastic polymer composition, and wherein the members (2, 3) are made, assembled together and fixed to each other in an integrated 2-step injection molding process. The invention also relates to a process for producing a housing for a radial flow compressor, comprising an intake pipe, a compressor duct and an outlet pipe, comprising steps of a) melt processing of a fiber-reinforced thermoplastic polymer composition thereby forming a polymer melt, b) injection molding the polymer melt into a molding die comprising at least two cavities, thereby forming at least two members comprising at least an upper housing member and a lower housing member, c) assembling the at least two members together, thereby forming a housing body defining the intake pipe, the compressor duct and the outlet pipe, and d) fixing the assembled at least two members to each other. |

1. A housing for a radial flow compressor, the housing comprising:
an intake pipe, a compressor duct, an outlet pipe, and a housing body made of a fiber-reinforced thermoplastic polymer composition and comprising at least an upper housing member and a lower housing member, wherein the upper and lower housing members are made, assembled together and fixed to each other in an integrated 2-step injection molding process whereby the upper and lower housing members are formed of a first injection molding shot of the fiber-reinforced thermoplastic polymer composition so as to define boundary spaces therebetween, and a second injection molding shot of the fiber-reinforced thermoplastic polymer composition fills the defined boundary spaces between the upper and lower housing members to thereby integrally fix one to another. |
