Magnesium frames offer approximately 30% lower weight than comparable aluminum frames. JWJ combines six semi-solid magnesium machines with mold manufacturing, CNC machining and surface finishing, connecting lightweight structures with the required interfaces and finished surfaces.
A semi-solid slurry flows under shear with a different filling behavior from fully liquid metal. Controlled filling reduces the conditions that promote gas entrapment; tooling and process settings still determine the result in the actual cavity.
JWJ can cast thin walls down to 0.6 mm with uniform wall thickness. Integrating housing walls, ribs and bosses starts with a coordinated review of wall transitions, filling paths and ejection, so the thin-wall geometry can be carried through into a finished component.
Lower thermal input can reduce shrinkage and distortion. Use near-net forming for the overall shape, then assign CNC finishing to the datums and interfaces that require it. JWJ reviews the casting and machining requirements as one route.
A dimensionally acceptable casting is only one stage of an appearance part. Visible areas, machining allowances and the subsequent coating route should be defined before tooling is finalized.
JWJ has high-acceptance-rate experience with magnesium e-coated appearance parts. We connect casting, machined surfaces and coating requirements early, so a downstream finish is considered while the upstream component is being planned.
