【Introduction: In Medicine, No Detail is Trivial; Precision is the Lifeblood】
In healthcare, particularly in ophthalmology, every detail of a product directly impacts patient well-being and treatment efficacy. Translating ingenious medical designs into mass-produced, zero-defect physical products demands not only cutting-edge technology but also an unyielding pursuit of extreme precision. When your innovative product faces micron-level challenges, you need a partner who understands the intricacies and can resolve complex issues.

We proudly present a groundbreaking success story that reconfirms our exceptional capabilities in high-precision medical injection molding.

【Challenge: A 1mm Micro-Hole – The Precision Test for Ophthalmic Products】
We recently undertook an injection mold development project for a medical ophthalmic product. While the material selected was medical-grade PA12, and the main product dimensions were D8x39mm, the core difficulties lay in:

• Extremely Fine Through-Hole Design: The product features an exceptionally challenging 1mm diameter through-hole in its center.
• Wall Thickness and Structure: Within the overall 3mm wall thickness, how could the stability and concentricity of this narrow micro-hole be guaranteed?
• Rigorous Tolerances: Medical devices demand extremely high dimensional accuracy; a perfectly concentric micro-hole is a prerequisite for its functionality.
• Scale and Consistency Requirements: With a 1x2 cavity mold configuration, how could perfect consistency be ensured between two products at such high precision, while also achieving efficient mass production?
  【Our Intelligent Solution: Meticulous Craftsmanship, Technology-Driven Empowerment】
  Faced with such stringent precision requirements, we didn't just rely on experience. Instead, we applied a systematic, data-driven "Precision Injection Molding Solution":

【Predicting the Future: Fine Mold Flow Analysis, Unveiling Injection Molding Mysteries】

Core Strategy: Before commencing mold fabrication, we conducted an extremely detailed mold flow analysis of the product. This was more than just a simulation; it was a precise pre-enactment and optimization of the future production process.
Key Outcome: Based on the analysis results, we determined the precise gate location to ensure optimal flow uniformity of the PA12 material as it filled the entire cavity, especially around the micro-hole. This simultaneously ensured uniform force on the embedded core pin, preventing eccentricity risks from the source.
【Conquering Eccentricity: Special Core Pin Technology, Forging a Precise Core】

• Core Strategy: To address the industry-wide challenge of eccentricity in slender micro-holes, we implemented a special design for the mold's core pin.

• Key Outcomes:

• Optimized Positioning: The mold core pin was precisely positioned at the top of the through-hole, like establishing a stable anchor for a critical support.

• Material Upgrade: We selected a special steel with extremely high elastic modulus for the core pin, endowing it with exceptional high-bend resistance. This ensured that the core pin remained perfectly straight under high-temperature, high-pressure injection molding conditions, resisting even the slightest deformation.
  【Trifecta: Seamless Integration, Flawless Creation】
  The three strategies – detailed mold flow analysis, precise core pin positioning, and special high-bend resistance steel core pins – organically combined to form a comprehensive solution. This perfectly resolved the world-class challenge of non-eccentric critical fine holes in medical ophthalmic products.
