What are the material selection requirements for Motor Housing?

Since the manufacturing materials of different aluminum motor housing will have different technical standards, it will be more guaranteed to choose according to actual needs, especially in terms of use effects, there will be very stable performance. According to actual needs, materials from well-known manufacturers are of better quality and more compliant.

What are the material selection requirements for Motor Housing?

When selecting materials, it is necessary to consider whether the material meets the performance requirements of Motor Housing, and also consider the development and application costs. Cast aluminum alloys need to have a certain stiffness and ductility, and the standard alloy EN AC-AlSi9Cu3(Fe) has a minimum yield strength (YS) of 140 MPa and an elongation at break of 1%. Yield strengths in excess of 180 MPa can be achieved in mass production after T5 heat treatment. To meet higher strength and elongation requirements, T6 heat treatment is required and alloys with higher ductility such as EN AC-AlSi8Cu3 are used, followed by CPS or gravity casting, which is also more cost-effective

What are the characteristics of using the low pressure casting process to produce the Motor Housing?

The low pressure casting process is characterised by its ability to carry out targeted and controlled mould filling. The optimum filling speed can be set according to the cross section to be filled, minimizing the formation of oxides and gaseous impurities. By using multiple risers, it is possible to achieve optimal material replenishment of the wall thickness build-up distributed in the casting, greatly suppressing shrinkage holes. The feeding capacity is decisively supported by a large number of individually controllable mould water cycles. In addition, the orientation of the temperature gradient from the casting to the feeder is adjusted accordingly. Mold water transport also plays an important role in the mold filling process. In particular, thin-walled areas away from the riser can only be filled ideally if the mold temperature is high enough. Under these technical conditions, the Motor Housing meets high mechanical performance requirements.

How is the Motor Housing produced?

The latest design of the Motor Housing is designed for die casting production. The requirements for castings are very strict. To meet component strength and corrosion resistance specifications, aluminum-silicon cast alloys with low iron and copper content are used. The cooling of the housing uses a liquid medium. Because there is no mass-production-suitable production technology capable of machining undercut inserts so far, in order to achieve a well-designed cooling structure around the motor, the housing is designed in two parts so as to be suitable for production with a die-casting process.

FHZL 3D sand printers, use sand to fabricate cores and molds for the sand casting process, various sand types can be accommodated for printing, including silica sand, ceramic sand and different kinds of synthetic sand.
