Introduction
PMMA CNC machined lampshades are light-transmitting lampshade parts formed by CNC milling from PMMA (polymethyl methacrylate) sheets or blocks.
Suitable for lighting products with specific requirements for light transmission, shape, and assembly dimensions, for sample verification, small-batch production, or customized lighting components.
Processing capacity
- Material Applicability Boundary Definition: PMMA has a light transmittance of approximately 92%, allowing for direct assessment of direct light, diffused light, or glare issues.
- Rationality of Shape and Optical Structure: Curved surfaces, grids, honeycomb structures, and other lampshade structures can be machined to verify light distribution schemes.
- Assembly Dimensionality: CNC machining dimensional tolerances can be controlled within ±0.05 mm, used for verifying mounting hole positions and interfaces.
- Material Selection Correctness: Physical samples confirm whether PMMA's scratch resistance, crack resistance, and appearance are acceptable in the current design.
- Need to Change Materials or Processes: The need to switch to PC, glass, or injection molding can be determined at the prototype stage.
MOQ, Lead Time, and Mass Production Capacity
- Minimum Order Quantity (MOQ): 1 piece or more, suitable for samples and small-batch customization.
- Lead Time Range: Typically 5–15 business days, depending on quantity, structural complexity, and surface treatment.
- Batch Applicability: Suitable for small-batch deliveries; larger batches require advance production scheduling and evaluation.
- Mass Production Integration: CNC-machined lampshades can be used as structural and appearance confirmation parts; for mass production, the cost and consistency of injection molding or other molding processes need to be evaluated.
Application Scenarios
PMMA CNC machined lampshades are widely used in:
- Indoor lighting fixtures: ceiling lights, chandeliers, fluorescent lamps, wall lamps
- Outdoor lighting: courtyard lights, landscape lights, waterproof lampshades
- Commercial lighting: shopping malls, exhibition lighting, advertising light boxes
- Automotive/traffic lighting fixtures: instrument lights, taillights, signal light covers
