From Metal 3D Printing to Finished Mold Insert — In-House, 7-Day Delivery
Get a Free QuoteMost mold quality problems are attacked at the wrong stage. We solve them at all three stages — before, during, and after molding.
3D-printed mold inserts with channels that follow part geometry. Eliminate hot spots, gate burn marks, and warpage at the source — before they happen.
Real-time cavity monitoring detects abnormal shots before they reach the next stage. Catch short shots, flash, and sticking automatically — no operator needed.
Automated optical inspection sorts good parts from defective ones at line speed. Replaces manual visual inspection — faster, more consistent, fully documented.
Metal 3D printing, conformal cooling mold inserts, CNC / EDM / WEDM machining, vision inspection systems, and injection molding production. Prototype samples or full production runs — all in one factory.
3D-printed mold inserts with cooling channels that follow your part geometry. Up to 72% faster cycles, gate burn marks eliminated.

Metal 3D printing machines in operation
When straight cooling channels can't reach the hottest areas of your mold, cycle times suffer, parts warp, and gate burn marks appear. Conformal cooling — only achievable through metal 3D printing — solves this at the source.
Cooling channels follow your exact part geometry — not just straight lines
Uniform heat extraction from all surfaces simultaneously
Eliminates gate burn marks on PETG, MS, and transparent plastics
Compatible with hot runner systems
Consistent cooling extends mold insert service life

All materials meet SPI-A1 polishing standard — suitable for transparent injection molded products.
Every number below comes from a documented customer project — before and after conformal cooling.
21s → 6s cooling time. Part temp: 93°C → 60°C. Gate burn marks eliminated.
880 → 1,320 pcs/day. Mold temp: 62°C → 48°C. Unit cost: ¥13.6 → ¥10.
1,760 → 3,046 pcs/day. 45s → 26s cooling. Unit cost: ¥3.50 → ¥2.60.

Conformal cooling uses 3D-printed cooling channels that follow the exact geometry of your mold cavity. Unlike conventional straight-drilled channels, this enables uniform heat extraction from all surfaces simultaneously — reducing cooling time by up to 72%. For example, a PETG bottle cap mold went from 21s to 6s cooling, and a Xiaomi humidifier mold increased output from 880 to 1,320 pieces/day.
We use 420 Mold Steel and 18Ni300 (Maraging Steel) for SLM-printed mold inserts. After heat treatment, parts achieve 50–55 HRC hardness. Surface finish can reach SPI-A1 (mirror polish), suitable for transparent products like PETG and PMMA.
Production takes 7–14 working days. We ship worldwide via DHL Express (3–5 days to Europe/US), FedEx, or sea freight. Total turnaround is typically 2–3 weeks from order to delivery.
Our prices are typically 50–70% lower than European metal 3D printing services. A conformal cooling insert costing €3,000–8,000 in Germany typically costs €800–2,500 with us, using equivalent materials and quality standards.
We operate 3 SLM machines (BLT A320 and E-Plus EP-M2), plus CNC milling centers, sinker EDM, wire-cut EDM, and injection molding machines. Our facility in Yuyao, Ningbo employs 35 people.
Yes — we are a full-service manufacturer. CNC milling, sinker EDM, wire-cut EDM, and plastic injection molding, all in-house. From prototype samples to full production runs, metal and plastic parts, no subcontracting.
