Custom Ultra High Precision Molds For Medical Optical Auto Parts Micron Accuracy

Custom Ultra High Precision Molds | Medical Optical & Auto Parts Specialized | Micron Accuracy | Direct Technical Service & One-Stop Processing

Ideal for Dual Fields: Medical Optical Parts (Endoscope Lenses, Surgical Microscope Lenses) & Auto Optical/Mechanical Parts (ADAS Camera Lenses, LiDAR Lenses, Auto Sensor Components) | Micron-level Accuracy (≤1μm Tolerance) | Compatible with Medical/Auto-Grade Materials (Medical PMMA, PC, Auto-Grade Optical Glass-Filled Resin) | Supports Medical Biocompatibility & Auto Harsh Environment Resistance Requirements

These custom ultra high precision molds are specially developed for the dual fields of medical optical and auto parts, focusing on solving the core pain points of "insufficient precision, poor environmental adaptability, and non-compliance with industry standards" in traditional ultra precision mold manufacturing. Unlike conventional machined molds that are difficult to balance medical biocompatibility and auto harsh environment resistance, our molds adopt high-precision electroforming technology (nickel ion layer deposition) to form a dense, stress-free structure with ultra-smooth surface (Ra ≤0.005μm), while achieving micron-level size control (≤1μm tolerance).

For medical optical applications, the molds use ISO 10993-compliant high-purity nickel materials to ensure low contamination and biocompatibility, meeting the strict requirements of medical devices such as endoscopes and surgical microscopes. For auto parts, the nickel-cobalt alloy molds have excellent high-temperature resistance (-40℃~180℃) and vibration resistance, perfectly adapting to the harsh working environment of auto ADAS cameras, LiDAR, and sensors. We provide direct one-stop service from technical communication to custom mold delivery, eliminating intermediate links to accurately match the personalized needs of dual-field products. Compliant with ISO 13485 (medical) and IATF 16949 (auto) industry standards, it is a reliable core mold solution for manufacturers pursuing high-quality medical optical and auto parts production.

With advanced electroforming technology and laser interference detection system, the key dimensions of the mold (diameter, curvature radius, feature position) are controlled within ≤1μm tolerance, and the surface flatness is ≤0.0005mm. For medical optical parts, this precision ensures clear imaging of endoscopes and surgical microscopes; for auto optical components, it avoids light refraction deviation of ADAS cameras and LiDAR, ensuring accurate environmental perception. For complex structures such as aspherical lenses and free-form surface sensors, the electroforming process can accurately replicate curved surfaces with 99.9% fidelity, meeting the high-precision assembly requirements of dual fields.

The mold materials and processes are tailored to the characteristics of dual fields: For medical optical parts, high-purity nickel materials comply with ISO 10993 biocompatibility standards, with no harmful substance precipitation, meeting the cleanliness requirements of medical devices; for auto parts, nickel-cobalt alloy materials have 50-55 HRC hardness, excellent high-temperature resistance (-40℃~180℃) and vibration resistance, adapting to the harsh working environment of automotive engine compartments and outdoor sensors. The ultra-smooth surface (Ra ≤0.005μm) ensures high light transmittance (≥92%) of optical parts, while reducing resin adhesion and avoiding molding defects.

• Stress-Free Structure: Electroformed molds have no internal stress, avoiding deformation under high-temperature molding (180-250℃) of medical/auto-grade resins, ensuring consistent quality of batch-produced parts;
• Strong Wear Resistance: Nickel-cobalt alloy materials support 500,000+ molding cycles without surface damage, greatly reducing mold replacement costs for mass production of auto parts; high-purity nickel molds for medical parts also have excellent wear resistance, adapting to small-batch and high-precision production needs;

• Diversified Customization: Support customized development of molds for different products (medical endoscope lenses, auto ADAS camera lenses, etc.), including size, structure, and material selection, to accurately match the unique requirements of each field.
