Spherical Cap Piezoelectric Ceramics

Spherical Cap Piezoelectric Ceramics

Custom focused piezo ceramics for OEM teams that need round spherical caps, annular / aperture caps, or custom curved variants in one sourcing path.

Features & Applications

We quote standard round parts from 7 mm to 115 mm diameter, group non-round curved parts as custom curved variants, and review rectangular or irregular pieces by diagonal length plus curvature and support condition.

Fast RFQ Fit Check

  • Round parts: diameter 7-115 mm with minimum wall thickness starting at 0.2 mm on small geometries.
  • Aperture variants: round-hole, square-hole, and annular shallow-cap shapes stay under the same product line.
  • Custom curved variants: segmented and non-round pieces are reviewed by effective size, diagonal, thickness, and support condition.

Diameter or Effective Size

Round parts are quoted by diameter. Rectangular or irregular curved variants are reviewed by diagonal length.

Minimum Wall Thickness

Starts at 0.2 mm

Smaller parts can start thinner, while larger focused ceramics move into thicker shell ranges for stable forming and handling.

Geometry Options

Round to custom curved

Spherical caps, aperture caps, curved segments, and non-round variants can stay under the same RFQ path.

Engineering Review

Special requests welcome

If your aperture shape, thickness target, or support condition falls outside the standard window, we review it with the technical team.

Size Range and Minimum Wall Thickness

Use this table as a first RFQ screen. Final feasibility still depends on curvature, aperture geometry, and support condition.

Special requests outside this window are not rejected automatically. They go into engineering review so the team can discuss thickness, tooling, and integration trade-offs before quoting.

Product Gallery

A single gallery layout makes it easier to compare real ceramic shapes, openings, curvature, and scale across the full spherical-cap range.

Round caps, aperture parts, curved segments, and scale-reference pieces are shown in one consistent format so the ceramic body stays clear and easy to compare.

Customization and Technical Review

The ceramic shape is only one part of the decision. Focused performance also depends on how the part is supported and loaded in the full assembly.

Geometry We Support

  • •Round spherical caps for focused acoustic output
  • •Annular and aperture caps with round or square openings
  • •Custom curved variants reviewed by effective span or diagonal length

What Engineering Reviews

  • •Curvature depth, shell thickness, and edge support condition
  • •Whether the part works in air, liquid, or an enclosed stack
  • •If the requested aperture or segment geometry changes manufacturability

Best RFQ Inputs

  • •Diameter or diagonal, target wall thickness, and any opening size
  • •Sketch, drawing, or sample photo showing curvature intent
  • •Operating frequency window, mounting method, and medium

Practical RFQ Shortcut

If you already have a sketch, drawing, or even only a marked sample photo, send it together with the target size, thickness expectation, and operating medium. That is usually enough for the engineering team to confirm whether the part should stay in the spherical-cap family or move into a more specialized review path.
