Solar Equipment Ceramic Parts are ceramic accessories for photovoltaic equipment manufacturers and maintenance projects. Typical parts include insulation components for coating equipment, ceramic heat shields for laminators, and chucks or locating parts for solar-cell test equipment. The finished geometry is matched to the machine interface.

Core Advantages

±0.01 to ±0.05 mm Equipment Fit

Dimensional accuracy is ±0.01 to ±0.05 mm. This range is used for ceramic chucks, locating blocks, and other equipment interfaces that must line up with an existing fixture or motion datum during replacement or new equipment assembly.

Ra ≤0.4-0.8 μm Working Surfaces

Working-surface roughness is Ra ≤0.4-0.8 μm. On faces that contact wafers, fixtures, or neighboring machine parts, the controlled finish limits raised machining marks and keeps the contact condition consistent between replacement batches.

Electrical Insulation Through Hot Zones

Insulation resistance is ≥10^13 Ω, and the maximum working temperature is 1500°C. These parts can sit near energized, heated assemblies in coating or heating equipment while maintaining electrical separation. The ceramic interface does this without introducing a low-temperature polymer at the same position.

Customization

Material and Purity

Material options include alumina, zirconia, and silicon nitride, with listed purity from ≥95% to 99%.

Component Geometry

Non-standard geometry can be produced from drawings or prototypes, including holes, slots, steps, curved profiles, and equipment-specific mating features.

Quality Control

Before production, the drawing is reviewed to identify the dimensions and interfaces that matter on the actual equipment rather than applying a generic inspection list to the ceramic shape. After machining, critical coordinates and finished geometry can be checked with dimensional measurement equipment.

Working surfaces, holes, slots, edges, and mating features are checked for size and visible defects. If the order includes electrical, thermal, or other functional requirements, the relevant performance items are sampled as part of inspection.

Finished parts are checked once more before packing, and the batch remains linked to its inspection records. Third-party inspection is accepted. Precision contact faces are separated in export packing to avoid part-to-part damage.
