Custom aluminum alloy shells for lithium battery and instrument applications are quoted to individual drawings. Shell geometry, tooling requirements and subsequent machining must be reviewed for the particular enclosure.
Confirm the alloy grade, delivery condition, surface finish and acceptance criteria before ordering. Dimensions and tolerances are defined feature by feature on the approved drawing; no single tolerance, hardness or thermal conductivity value is claimed for every part. Any required material records or test reports should be listed with the enquiry.
Send a legible drawing with revision, order quantity, delivery destination and the required manufacturing scope. A 3D model may supplement the controlled drawing. Identify critical interfaces and requested documents so that the quotation can state the agreed scope, lead time and commercial terms.
These existing photographs show examples of machined parts. They do not establish the pictured material grade, an exact application, vehicle compatibility or the geometry of the product being quoted. The requested component is defined by its approved drawing.
