Precision Die-Cut Silicone Washers
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.
Key Features
Flat Silicone Parts from Cured Sheet
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.
-
Cured Silicone Sheet
Parts are cut from pre-cured silicone sheet rather than formed in a mold, keeping the process focused on flat profiles.
-
2D Profile Cutting
Round washers, discs and custom outlines can be cut from 2D drawings, including holes and slots where the geometry allows.
-
Sheet Thickness Selection
Thickness is selected from available silicone sheet stock and confirmed against the drawing before cutting.
-
Cutting Tolerance Review
Critical dimensions are reviewed according to material thickness, profile geometry, hole size and cutting method.
-
Adhesive & Release Liners
Pressure-sensitive adhesive and release-liner options can be specified to support positioning, handling and assembly.
-
Prototype & Short Runs
Die cutting is suitable for sample evaluation, design verification and short production runs of flat sheet-cut parts.
Technical Data
Sheet-Cutting Specifications
Key parameters are defined by the cured silicone sheet, 2D geometry and secondary options rather than molded three-dimensional features.

Manufacturing Comparison
Die-Cut vs. Molded Silicone Washers
Choose the Right Process
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 |
Prototype and Short-Run Support
Die cutting supports sample evaluation and short production runs without requiring molded three-dimensional geometry. Sheet, drawing and tooling requirements are reviewed before cutting.

Where It's Used
Typical Flat-Part Uses
These parts are used where a flat sheet-cut component can provide spacing, isolation, cushioning or a simple sealing interface.
-
Equipment Housings
Flat washers and pads can be placed between covers, housings or brackets where thickness is controlled by the selected sheet stock.
-
Panel & Fastener Interfaces
Sheet-cut profiles can be used around panels, fasteners and contact points where a flat geometry is sufficient.
-
Adhesive-Backed Mounting
PSA-backed parts can support positioning during assembly or add a localized cushioning and contact surface.
-
Electrical Isolation
Flat silicone spacers or washers can be used where dielectric separation or vibration isolation is required.
-
Water & Sanitary Assemblies
Project-specific silicone grades can be reviewed where water-contact or sanitary requirements apply.
OEM & Custom
Design & Conversion Review
Before cutting, we review the 2D drawing, selected sheet thickness, critical dimensions, hole and edge relationships, and any adhesive or liner requirements.
-
2D Drawing Review
Confirm outside and inside dimensions, slots, cutouts and critical features from a 2D drawing or physical sample.
-
Sheet Thickness Selection
Select a suitable silicone sheet grade and available thickness before finalizing the cut profile and dimensional checks.
-
Hole & Edge Limits
Small holes, narrow walls and short edge distances are reviewed against sheet thickness and part geometry before production.
-
Adhesive & Liner Setup
Adhesive type, application side and release liner can be defined according to handling, positioning and assembly requirements.
