As an injection mold manufacturer specializing in camera molds, we cover 20 product categories including home appliances, daily necessities, medical devices, digital products, connectors, and electronic components. Below is a practical case study following the "Problem-Analysis-Solution-Outcome" framework—tailored for solution evaluation and strategic decision-making—with a focus on camera-specific precision and sustainable manufacturing.
A consumer electronics brand faced critical challenges with smartphone camera module molds:
• Optical distortion: ±0.008mm dimensional tolerance failed to match lens assembly requirements, causing 15% image blurring complaints
• High defect rate: 11% of parts had sink marks due to uneven cooling, affecting lens alignment
• Incompatibility with anti-shake components: Molded housings couldn’t accommodate OIS (Optical Image Stabilization) modules smoothly
• Unsustainable production: 10.8kW·h per mold cycle and 18% plastic waste rate failed to meet green product certifications
• Material mismatch: Generic mold steel lacked wear resistance for high-precision camera component molding
• Structural flaw: Traditional cooling channels ignored camera housing’s complex cavity structure, leading to uneven shrinkage
• Standard inconsistency: Incompatibility with DEM/HASCO/MISUMI standards delayed cross-supplier collaboration
• Sustainability oversight: No mold design optimization for recycled plastic flow or energy conservation
We developed a targeted solution integrating optical precision and sustainability:
• Material & Standards: Adopted S136 stainless steel with mirror polishing, fully compatible with DEM, HASCO, MISUMI, and Mold-Bao standards; supported STEP/X_T drawing formats for seamless data transfer
• Process Innovation: Applied digital twin mold flow simulation to optimize cavity pressure distribution, designed conformal cooling channels to reduce temperature variation by 45%, and achieved Ra 0.005μm surface finish for optical compatibility
• Eco-Innovation: Used 92% recyclable mold base materials, upgraded to energy-saving servo systems, and optimized runner design for 32% PCR (post-consumer recycled) plastic compatibility
• Social Responsibility: Complied with ISO 14001/45001 certifications, sourced 100% low-carbon raw materials, and established a mold lifecycle recycling program
