Precision Mold Base & Core Insert Machining

We provide high-precision machining services for mold bases and core inserts used in plastic injection molds, die casting molds and various industrial tooling applications.

With advanced CNC machining centers, EDM processing and strict dimensional inspection control, we ensure stable quality, tight tolerance and fast delivery for customized mold components.

1. Mold Base Precision Machining

Our mold base machining service includes:

• Rough machining and finish machining (황삭 / 정삭)

• Drilling, tapping and precision boring

• Guide pin & bushing hole machining

• Cooling channel processing

• Precision surface grinding

• Assembly surface flatness control

Tolerance: up to ±0.01mm
Surface finish: Ra0.8 or customized requirement

The mold base provides structural stability and alignment accuracy for the entire mold system. We focus on parallelism, perpendicularity and alignment precision to ensure smooth mold operation and long service life.

2. Core Insert (Mold Core) Precision Machining

Core inserts directly determine product shape and dimensional accuracy. Our core machining capabilities include:

• 3/5-axis CNC precision machining

• EDM machining for complex geometry

• Precision slot and cavity processing

• Fine finishing & polishing

• Tight tolerance control for assembly fitting

Tolerance: up to ±0.005mm
Material: P20, 718H, S136, H13, SKD61, customized steel

We ensure perfect matching between core and cavity, reducing flash, deformation and dimensional deviation during molding.

3. Quality Control

Every mold base and core insert is inspected before shipment:

• CMM (3D coordinate measurement) inspection

• Dimensional inspection report available

• Surface roughness inspection

• Hardness testing (if required)

We strictly control processing accuracy at every stage to ensure stable mold performance for mass production.
