Die Casting & Metal Net-Shape Parts
When housings need net-shape efficiency, HC-Mold supports aluminum and zinc die casting with tooling discussion, sampling and secondary machining for sealing faces and precision holes. Prototypes often start on CNC so design risk is burned down before dies are cut.
How HC-Mold runs this work
- Aluminum and zinc die casting pathways with project DFM
- Secondary CNC for CTQ faces, threads and datums
- Cosmetic or corrosion finishes after casting and machine

Materials we commonly run
Aluminum and zinc alloys common to enclosure and bracket work. Alloy callouts and porosity expectations belong in the RFQ — not assumed from a generic “die cast” label.
RFQ checklist
01
Share files & intent
STEP/IGES/PDF drawings, material callout, volume band, finish target and ship-to region.
02
DFM & quote
Engineering review with process recommendation, risk notes and lead-time options — no instant-CAD black box.
03
Build & ship
In-process checks, outgoing reports and export packaging from the Chang’an campus.
FAQ — Metal Casting
Should every metal housing be die cast?
No. Low volume, frequent changes or extreme flatness often stay on CNC or sheet. Casting wins when annual volume and geometry amortize the die.
Do you prototype before cutting dies?
Usually yes — CNC or printed masters catch packaging and assembly issues cheaply before tooling commitment.
