Optical System Design Services
Core Services: Optical Processing and Coating
We also provide Optical Components with ultra-precision machining of optical plastics using Single Point Diamond Turning (SPDT). Leveraging the robust technological expertise of our doctoral team, we achieve one-step molding. This processing method involves our self-developed machining techniques, enabling high-precision machining on specific optical resin blocks (such as PMMA, PC, COP, and other types of optical resins) to attain superior optical surface quality. This approach typically offers the following advantages:
Cost and Time Savings for Molds: For small-batch production or prototype development, direct cutting eliminates the high costs and long lead times associated with mold fabrication. It is a more economical (costing just a few thousand dollars) and flexible (completed within a few weeks) solution for customers with small-batch or specialized requirements.
Rapid Validation: Direct cutting facilitates easy customization of complex structures, including aspheric and diffractive elements, making it ideal for product development that demands multiple iterations and quick validation. This method provides exceptional flexibility, especially for customers in laboratory settings or specialized applications.
High-Precision Assurance: Since the cutting process bypasses the injection molding stage, it eliminates issues such as material shrinkage. This enables products to achieve extremely high precision and surface quality, making it particularly suitable for applications requiring ultra-high optical surface accuracy, such as scientific research, medical equipment, or high-end imaging systems.
Avoidance of Heat Treatment Effects: Injection molding involves heating plastics, whereas cutting occurs at room temperature. Optical resins remain more stable during the cutting process, preventing stress and deformation caused by temperature fluctuations and ensuring higher optical surface accuracy and consistency.
Compatibility with Innovative Materials: Some new optical resin materials do not perform well at high temperatures. Direct cutting helps avoid the degradation of material properties, ensuring that the optical characteristics of these materials remain intact during processing.
YIGHEN ULTRA PRECISION caters to customers who are ordering plastic lens mold cores. Particularly, We offer mold cores made of hardened stainless steel, a nickel-free material known for high precision and top-notch quality. Our mold core products have won wide recognition from customers. Additionally, we provide optical components made of soft materials (such as aluminum and copper mirrors) to meet the diverse needs of our customers. Our customers are across Asia, America, Europe, Oceania, and other regions.
To satisfy customers' various technical requirements, the company manufactures various mold cores, including spherical, aspheric, Fresnel, multi - planar, diffraction, matrix (lens array), and hybrid molds. Our extensive range of mold cores is used in mobile phone camera lenses, laser mice, flashes, digital read-write heads, optical fiber connectors, biomedical applications, and various optical sensor fields, this endows customers' products with an excellent optical performance and high stability.
Regarding the precision of mold core surface processing, the company has independently developed the "Injection Molding Shrinkage Error Compensation Algorithm Software". This software can perform profile correction before processing according to customers' needs, significantly improving the precision after injection molding and notably enhancing the quality of customers' products. Our mold cores are produced using direct cutting steel technology, ensuring durability even in a 300 - degree Celsius high - temperature environment, which is highly suitable for high - performance plastic injection molding production. By optimizing the production cycle and boosting efficiency, we have significantly cut down our customers' production costs.
Our ultra - precision machining capabilities can handle mold cores with a less than 30mm diameter. Most of these mold cores have a diameter of less than 8mm, and the minimum size can even be less than 1mm. We can achieve a precision up to a sagittal height - to - caliber ratio of 0.4, a surface roughness (Ra) below 8 nm, and a profile accuracy controllable within 0.2 microns (PV value), meeting the high - precision requirements of our customers.
