example 1

[0066] A fiber-reinforced thermoplastic and thermally stable PA46 compound, Stanyl Diablo OCD2100, is used as material. A mold slide injection molding dual-cavity mold with cavities for the upper and lower housing parts for the molding of a compressor housing with a diameter of about 10 cm is incorporated in the injection molding member comprising an injection molding extruder group. The temperature settings and injection pressure of the injection molding extruder and the temperature settings of the mold were adjusted to standard molding conditions for the Stanyl material. Inject material into the two cavities, change the position of the cavities so that the two injection molded parts are placed next to each other, forming the shape of the compressor housing while leaving an open channel at the contact area of ​​the two injection molded parts, and placing The material from the second injection is injection molded in this channel. The shell is demoulded while the shell thus f...

Abstract

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 fibre-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 fibre-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.

Description

technical field [0001] The present invention relates to housings for radial compressors, in particular for automotive turbochargers, and more particularly to housings made of plastic. The invention also relates to a process for manufacturing the plastic housing. Background technique [0002] In order to provide the greatest possible amount of fresh air in the cylinders, radial compressors such as turbochargers are installed in the region of the intake tract of motor vehicles. In this way the air is already precompressed outside the cylinder. Due to the enormous pressures that develop within the housing of a radial compressor, the housing should be constructed sufficiently robust. [0003] Cars are now usually provided with turbochargers. Conventional housings of turbochargers are made of aluminum. In recent years, automotive components made of metal have tended to be replaced by parts made of plastic in order to save weight and enable further functional integration. How...
