From 2D drawing to finished, inspected, shipped part — we handle every step in-house. Mold steel, maraging steel, tool steel. 50–55 HRC. SPI-A1 capable. Global shipping from Ningbo.
Every step handled by our team. No external subcontracting for core manufacturing steps.
| Material | Grade / Type | Hardness (HRC) | Primary Applications | Key Advantage |
|---|---|---|---|---|
| 420 Mold Steel | Martensitic stainless | 50–52 HRC | General injection mold inserts | Cost-effective, good corrosion resistance |
| 18Ni300 Maraging Steel | Ultra-high strength | 52–55 HRC | High-performance, long-run molds | Excellent toughness + hardness combination |
| MS1 | Maraging steel variant | 50–52 HRC | Standard mold inserts, high-wear areas | Good polishability, extended service life |
| M2 | High-speed tool steel | 53–55 HRC | High-wear, high-abrasion applications | Highest wear resistance in the lineup |
