Optical Design

Optical Design serves as the foundational stage of the entire process, with the core objective of ensuring the lens meets predefined optical specifications while providing accurate references for subsequent mold design.

Upon receiving design requirements, the optical engineer's primary task is to verify the completeness of all relevant documents to ensure no design information is missing. The essential documents and their purposes are as follows:

  • Lens 2D and 3D drawings
  • LED specification and LED Rayfile
  • IES/Dialux/AGI files/ Beam Angles
  • Lens material (PC/PMMA)
  • PCB board drawings
  • Luminaire heatsink drawings/assembly 3D drawing

Mold Design

Based on the 3D drawings of the optical lens, the mold engineer utilizes 3D design software such as Pro/E, UG, and SolidWorks to complete the comprehensive 3D structural design of the mold. The drawings must encompass all critical components including the cavity, core, runner system, gate, cooling channels, and ejection mechanism to ensure the mold structure meets injection molding requirements.

Material Ordering

After the mold drawings are confirmed, the procurement process for core mold materials is initiated. To ensure the mold's wear resistance, polishing performance, and service life, the mold base, mold frame, and mold core of the lens mold are made of imported ASSAB S136 steel. This steel offers excellent corrosion resistance and mirror polishing potential, making it an ideal material for optical molds.

CNC Machining

CNC Machining utilizes computer-programmed controls to direct precision cutting tools, executing the primary shaping of mold cavities and cores. Its accuracy fundamentally determines the dimensional precision of the mold base.

  • 14 CNC Machining Centers
  • 2 Ultra-Precision CNC Machines (Models: UVM-450C (V2), UVM-4500(H))
  • 5 High-Speed CNC Machining Centers (Roders, Apas, Xinquan)

Wire EDM

Wire EDM (Wire Electrical Discharge Machining) operates on the principle of electrical discharge erosion, making it particularly suitable for machining non-rotational asymmetric holes and sharp corner structures in molds. It can perform precision machining after quenching, effectively avoiding distortions caused by heat treatment.

EDM

EDM (Electrical Discharge Machining), while sharing the same electrical discharge erosion principle as Wire EDM, utilizes electrodes complementary to the cavity shape for three-dimensional copy milling. This process excels at handling deep cavities, narrow slots, and complex surfaces within molds, enabling the creation of geometries unachievable through traditional machining methods.

Manual Polishing

Manual Polishing remains an irreplaceable core process in current manufacturing technology, where the experience and judgment of skilled technicians directly determine the optical quality of the mold surface. Experienced technicians perform meticulous surface polishing to achieve a mirror finish that meets stringent optical product requirements.

  • Compensating for prior-stage imperfections
  • Achieving ultimate precision
  • Deterministic form correction
  • Enhancing production performance

Mold Assembly and Testing

Mold Trial serves the core objective of verifying mold performance and optimizing injection parameters, thereby establishing a reliable foundation for mass production. Mold engineers are responsible for assembling the molds and conducting trial runs, inspecting both mold functionality and product quality to ensure the mold can consistently produce qualified optical products.
