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.
