NAK80 Multi-slide Mold
This NAK80 multi-slide mold is a high-precision, long-life mold designed for complex-structure precision injection molded parts. Made of NAK80 pre-hardened mirror steel, processed via multi-axis CNC machining, EDM and precision assembly, it integrates multi-slide core-pulling mechanisms to enable one-time forming of undercuts, side holes and other complex structures. Widely used in the production of precision parts in automotive, consumer electronics, medical and other industries.
- Machining Process: Multi-axis CNC machining, EDM, precision assembly
- Material: NAK80 Pre-hardened Mirror Mold Steel (S136/H13 optional upon request)
- Accuracy: ±0.005 mm
- Surface Finish: Mirror polish
- Mold Life: Over 500,000 cycles (customizable as required)

We specialize in custom manufacturing of high-precision injection molds, equipped with 5-axis machining centers, wire-cut EDM, mirror spark machines and other full set of precision processing equipment, with over ten years of experience in complex-structure mold development. The key dimensional tolerance of the mold is stably controlled within ±0.005 mm, with a monthly delivery capacity of 20+ medium and large precision molds. We provide one-stop services from product structure optimization, mold design, manufacturing to trial molding and delivery, serving customers in automotive, medical, electronics and other industries.
Technological Process
- Product & Mold Design: Optimize parting lines and core-pulling solutions based on product structure, complete 3D mold design and 2D machining drawings.
- Steel Cutting & Rough Machining: Cut NAK80 steel to size and perform rough milling to remove most of the excess material.
- Semi-finishing & Heat Treatment: Semi-finish the mold components and perform pre-hardening treatment to stabilize NAK80 hardness at HRC38-42.
- Precision Machining: Multi-axis CNC finish the cavity, slides and guide pin holes; wire-cut EDM process inserts and holes; EDM finish sharp corners and ribs.
- Surface Treatment & Polishing: Conduct mirror polishing, grain or spark texture treatment as required to improve appearance and demolding performance.
- Mold Assembly & Trial Molding: Complete mold assembly, conduct multiple trial moldings and adjustments to ensure product dimensions and appearance meet requirements before delivery.
