As an injection mold manufacturer specializing in medical syringe molds, we cover 20 product categories including home appliances, daily necessities, medical devices, digital products, connectors, and electronic components. Below is a practical, hands-on case study following the "Problem-Analysis-Solution-Outcome" framework—tailored for solution evaluation and strategic decision-making—with a focus on medical-grade precision and sustainable practices.
A leading medical device enterprise faced urgent challenges with syringe barrel molds:
• Failed biocompatibility tests: Generic mold materials leached impurities, failing ISO 10993 standards
• Dimensional inaccuracy: ±0.01mm plunger fit tolerance caused 12% leakage complaints
• Low production efficiency: 38-second molding cycle couldn’t meet 150k-unit monthly demand
• Unsustainable processes: 19% plastic waste rate and 11.5kW·h/cycle energy consumption failed green certifications
• Material mismatch: Non-medical-grade mold steel lacked corrosion resistance and biocompatibility
• Structural flaw: Traditional cooling channels led to uneven shrinkage, affecting plunger sealing
• Standard inconsistency: Incompatibility with DEM/HASCO/MISUMI medical mold standards delayed regulatory approval
• Sustainability oversight: No design optimization for recycled medical-grade plastic flow
We developed a targeted solution aligning with medical rigor and sustainability:
• Material & Standards: Adopted S136 medical-grade stainless steel (biocompatibility certified), fully compatible with DEM, HASCO, MISUMI, and Mold-Bao standards; supported STEP/X_T drawing formats for seamless regulatory documentation
• Process Innovation: Applied AI-powered mold flow simulation to optimize cavity wall thickness, designed conformal cooling channels to reduce temperature variation by 48%, and achieved Ra 0.006μm surface finish to prevent residue buildup
• Eco-Innovation: Used 93% recyclable mold base materials, upgraded to servo-driven injection systems, and optimized runner design for 35% PCR (post-consumer recycled) medical plastic compatibility
• Compliance Focus: Integrated ISO 13485 quality management into mold production, ensuring full traceability of raw materials
