Die-cut silicone washers are produced from cured silicone sheet and are best suited to flat, two-dimensional profiles. Thickness is selected from available sheet stock, while holes, slots, adhesive backing and release liners can be customized to the assembly.
These parts are cut from cured silicone sheet for flat, two-dimensional profiles. Sheet thickness, holes, slots, adhesive backing and release-liner requirements can be defined from the drawing before production.
Parts are cut from pre-cured silicone sheet rather than formed in a mold, keeping the process focused on flat profiles.
Round washers, discs and custom outlines can be cut from 2D drawings, including holes and slots where the geometry allows.
Thickness is selected from available silicone sheet stock and confirmed against the drawing before cutting.
Critical dimensions are reviewed according to material thickness, profile geometry, hole size and cutting method.
Pressure-sensitive adhesive and release-liner options can be specified to support positioning, handling and assembly.
Die cutting is suitable for sample evaluation, design verification and short production runs of flat sheet-cut parts.
Key parameters are defined by the cured silicone sheet, 2D geometry and secondary options rather than molded three-dimensional features.

| Starting Material | Cured silicone sheet |
| Manufacturing Method | Die cutting / precision cutting from sheet |
| Profile Type | Flat 2D profiles |
| Sheet Thickness | Selected from available sheet stock; confirm by drawing |
| Cutting Tolerance | Reviewed by sheet thickness, geometry and cutting method |
| Hole / Slot Design | Minimum size and spacing reviewed per drawing |
| Edge Distance | Reviewed against sheet thickness and part geometry |
| Adhesive Backing | Optional pressure-sensitive adhesive as specified |

| Compliance Options | FDA / NSF grade options and RoHS / REACH requirements confirmed by project |
Die-cut silicone washers are cut from cured sheet and are best for flat 2D profiles, adhesive-backed parts, prototypes and short runs. For lips, grooves or other molded 3D geometry, use Silicone Molded Seals.
| COMPARISON | DIE-CUT SILICONE WASHERS | MOLDED SILICONE WASHERS |
|---|---|---|
| Manufacturing Process | Cut from cured silicone sheet | Formed and cured inside a mold |
| Best For | Flat washers, discs, pads and gaskets | 3D shapes, lips, grooves and complex profiles |
| Tooling Cost | Usually lower for simple flat profiles | Usually higher due to compression or injection molds |
| Thickness | Based on available sheet thickness | Custom molded thickness and geometry |
| Adhesive Backing | Available on one or both sides | Usually applied as a secondary process |
| Prototype Suitability | Suitable for samples and short runs | Better suited to stable molded designs |
Die cutting supports sample evaluation and short production runs without requiring molded three-dimensional geometry. Sheet, drawing and tooling requirements are reviewed before cutting.
Flat Sheet-Cut Parts
Prototype & Low-Volume Support
These parts are used where a flat sheet-cut component can provide spacing, isolation, cushioning or a simple sealing interface.
Before cutting, we review the 2D drawing, selected sheet thickness, critical dimensions, hole and edge relationships, and any adhesive or liner requirements.

Confirm outside and inside dimensions, slots, cutouts and critical features from a 2D drawing or physical sample.
Select a suitable silicone sheet grade and available thickness before finalizing the cut profile and dimensional checks.
Small holes, narrow walls and short edge distances are reviewed against sheet thickness and part geometry before production.
Adhesive type, application side and release liner can be defined according to handling, positioning and assembly requirements.
