When your CAD file finally leaves the screen and becomes a 400-ton aluminum housing, the single variable that decides success or scrap is the die casting mold. At Junying Diecasting-mould.com we don’t just cut steel; we build multi-slide, unscrewing, insert-exchange tools that hit ±0.02 mm on day one and still hold tolerance after 500 k shots. That’s why OEMs from Tesla-tier EV plants to boutique drone start-ups call us the die casting mould manufacturer that keeps them ahead of launch windows.
What separates our die-casting mold making?
-
Mold-flow before steel – Magma simulation on every gate, runner and overflow so you see air traps before the first chip flies.
-
H-13 premium steel vacuum-hardened to 48-52 HRC, TiN-coated cores for brass jobs that normally erode in 20 k cycles.
-
Conformal-cooled inserts printed in maraging steel; cycle time drops 18 % on average, paying for the tool in months, not years.
-
On-site 5-axis Mazak cells finish cavities to Ra 0.2 µm, eliminating hand-polish variability that causes parting-line flash.
Process snapshot (real 2024 job):
Customer needed a zamak 5G antenna housing, 0.5 mm wall, 120 mm long, IP67 seal groove. We built a 4-cavity die casting mold with hydraulic slides and beryllium-copper cores for heat extraction. First T0 shot ran at 38 seconds, porosity under 2 %, zero draft on seal face achieved through vacuum assist. Tool cost 18 % less than their previous EU quote, delivered in 28 calendar days.
Services bundled with every tool:
✅ Dfm + quote in 24 h – you get a live spreadsheet: cycle estimate, part weight, gate velocity, trim force.
✅ Prototype inserts – 3-D printed H13 so you can validate critical dims while the production die casting mould is hardened.
✅ Lifetime maintenance – free parting-line weld touch-up within the first 50 k shots; spare ejector pins stocked at no charge.
