Capabilities
Machining Capabilities for Tool Steel & Mold Steel
CAP / 01
CNC Milling for Tool Steel
Block milling, cavity roughing, and precision finishing on D2, H13, P20, S136, NAK80, and pre-hardened grades. Suitable for mold plates, inserts, and wear blocks.
CAP / 02
CNC Turning for Precision Steel Parts
Round punches, guide pins, bushings, and cylindrical die components turned from tool steel bar stock with tight OD/ID tolerances.
CAP / 03
5-Axis Machining for Mold Inserts
Complex mold cores, cavity inserts, and multi-surface tooling components machined in a single setup — reducing re-fixturing error on critical parts.

2
Rough Machining
Block stock roughed to near-net shape with controlled stock allowance.
3
Precision Machining
Cavities, profiles, holes, and fit surfaces finished to drawing tolerance.
4
HT / Finishing
Heat treatment, polishing, or grinding coordinated before final delivery.
5
Inspection & Delivery
Critical dimensions verified. Parts packed with protection and documentation.
Why Choose Us
Why Machine Tool Steel & Mold Steel With Us
Tool steel and mold steel parts require harder materials, tighter dimensional control, and coordination with downstream processes like heat treatment and polishing.
1
Experience with Mold Steels & Wear-Resistant Steels
Routine machining of D2, H13, P20, S136, NAK80, and M2 — in both annealed and pre-hardened conditions.
2
Suitable for Inserts, Cavities, Dies & Tooling Parts
Deep cavities, precision bores, cooling channels, and complex mold surfaces machined with controlled tool strategies.
3
Better Control for Dimensional Accuracy
Process planning accounts for material stress, hardness, and heat treatment distortion — not just generic CNC tolerances.
4
Prototype Tooling to Recurring Production
From single-piece prototype inserts to recurring batch production of die components — same facility, same quality system.
