Injection Mould Base

Injection mould base features precise guiding system, high structural rigidity and excellent dimensional stability, widely applied to mould fabrication for automotive dashboards, household appliances, medical devices and consumer electronics.

Standard: Custom or standard mold base system
Technique: Fabricated from pre-hardened plates. Ready for direct cavity machining. All plates blanchard ground before hole drilling and pocket milling
Shape: Standard two-plate or three-plate mold bases. Custom oversized dimensions available
Heat treatment: Plates used in pre-hardened condition (28–34 HRC). No further heat treatment needed. Inserts can be hardened if required
Surface Treatment: Ground Ra ≤0.8 μm on critical faces. Electroless nickel plating optional for corrosion resistance. Standard anti-rust oil shipping
Tolerance: Flatness: 0.02 mm/1000 mm. Parallelism: 0.03 mm/1000 mm. Ejector plate stroke accuracy ±0.05 mm
MOQ: 1 set

We supply Injection Mould Base in various custom sizes

Core Quality Inspection

Inspection Item	Standard / Method	Acceptance Criteria / Typical Value	Description
Material Certification & Ultrasonic Testing (UT)	EN 10204 Type 3.1 + ASTM A578 / EN 10160	Pre-hardened steel per spec (e.g., 1.2311 28-34 HRC); No discontinuities ≥ 2 mm	Traceable mill certs and UT scan guarantee plate integrity, preventing sudden deformation or cracking under sustained clamping forces.
Flatness & Parallelism	DIN 876 / CMM	Flatness: 0.02 mm / 1000 mm; Parallelism: 0.03 mm / 1000 mm	Precision-ground parting faces ensure perfect mould alignment, eliminating flash and uneven wear on cavity and core components.
Pin & Bushing Concentricity	CMM / Dial Gauge	Concentricity ≤ 0.02 mm	Verified alignment of leader pins and bushings guarantees smooth mould open/close without binding, maintaining cycle speed and accuracy.
Cooling Line Hydrostatic Test	Hydrostatic Test	10–15 bar, 30 min; Zero pressure drop	Leak-free confirmation of all water circuits ensures stable mould temperature control, preventing hot spots, warpage, and extended cycle times.
Ejector System Function Check	Manual Assembly & Dial Gauge	Ejector plate parallelism 0.05 mm; Guide pillar sliding clearance H7/f7	Complete inspection of ejector plates, pins, and bushings ensures reliable, jam-free ejection without flash or part damage.

Note: In addition to the above core inspections, NingShing performs full multi-point hardness testing on all plates (ASTM E18), surface finish measurement on critical faces (ISO 4287, Ra ≤0.8 μm), CMM verification of all pocket, hole, and T-slot locations, and complete pre-assembly and sliding function tests. Every injection mould base is delivered with a comprehensive inspection report, ensuring immediate installation and production readiness.
