In injection molding, Mold Frames (or mold bases) serve as the foundational skeleton that holds every critical component—from cavities and cores to ejector systems—in perfect alignment. At Hongxin Mold, we engineer industrial-grade Mold Frames that withstand high-pressure cycles while maintaining micron-level accuracy. Unlike generic suppliers, our frames integrate standardized components (like GUIDE PINS, SPRUE BUSHINGS, and SUPPORT PILLARS) with custom geometry tailored to your project’s lifecycle demands.
Engineering Excellence: How Hongxin Mold Builds Superior Mold Frames
Our Mold Frame manufacturing process combines CNC milling, EDM, and precision grinding to achieve flatness within ±0.02mm. We use:
-
Material Selection: P20, 718H, or H13 steel for optimal hardness (28-32 HRC) and fatigue resistance.
-
Modular Design: Pre-machined slots for effortless insertion of lifters, sliders, and cooling lines.
-
Dimensional Rigidity: 4-jaw chuck turning ensures squareness tolerance <0.01mm across platen surfaces.
Custom Mold Frame Capabilities for Complex Applications
Hongxin Mold specializes in non-standard Mold Frame configurations for industries requiring ultra-precise tooling:
-
Automotive: Multi-cavity frames with integrated hot-runner systems for headlight housings.
-
Medical: ISO Class 7-compliant frames with electropolished surfaces to prevent particulate contamination.
-
Cosmetics: Mirror-finish frames for lipstick molds using S136 stainless steel.
The Hidden Cost of Compromised Mold Frames
A poorly manufactured Mold Frame causes cascading failures: parting-line flash, misaligned cores, and premature wear. Hongxin mitigates risks through:
-
FEA Simulation: Stress analysis of frame deflection under 250+ tons of clamping force.
-
Tool-Tryout Reports: Dimensional validation reports pre-shipment.
-
Hardness Mapping: 15-point Rockwell testing on all load-bearing pillars.
Case Study: High-Volume Packaging Mold Frame with 0% Downtime
A European client required a 64-cavity Mold Frame for thin-wall yogurt lids. Hongxin delivered a 1050mm × 780mm frame featuring:
-
Interchangeable inserts for rapid changeovers
-
Conformal cooling channels reducing cycle time by 22%
-
DME-standard ejector pin grid Result: 18 months of uninterrupted production with <0.005mm warpage.
Partnering with Hongxin Mold: From Prototype to Mass Production
Whether you need an ASTM A681-compliant Mold Frame or a fully machined mold base with LKM standards, our workflow includes:
-
Blueprint Review: DFM feedback within 24 hours
-
Block Machining: Roughing with φ50mm carbide end mills
-
Thermal Stress Relief: 600°C tempering to eliminate internal tensions
-
Final Finishing: Jig grinding for RA 0.4μm surface finish
Conclusion: Precision Matters in Every Mold Frame Layer
A Mold Frame isn’t just metal—it’s a precision-engineered ecosystem determining mold longevity, part quality, and ROI. Hongxin Mold’s vertically integrated facility (from steel sourcing to QC) guarantees frames with >1 million-cycle durability. Request your mold base quotation today at www.hongxin-mould.com.
