Custom Profiling & Shaping for Foam, Rubber & Gasket Fabrication
Profiling, skiving, contour cutting, and fabrication-to-shape of engineered materials: skived sheet to thickness, profiled strip and edge shapes, contour and shaped parts, beveled and chamfered edges, and built-up bonded profiles. Drawn from solid silicone, neoprene, and EPDM, BISCO® [TDS] and PORON® [TDS] foams, cork, felt, and UHMW. Often combined with die cutting and lamination for finished parts. Shaped to your drawing in Winsted, Connecticut.
Built for: custom gasket profiles, edge trim and protective edging, shaped pads and bumpers, skived sheet brought to a target thickness, and built-up bonded constructions finished to print.
Custom profiling & shaping at H-O Products goes beyond flat cutting: skiving sheet to a target thickness, profiling strip and edge shapes, contouring and shaping parts, beveling and chamfering edges, and building up bonded profiles into finished constructions. Work runs in solid silicone, neoprene, and EPDM, BISCO® and PORON® foams, cork, felt, and UHMW PE from the 687+ material inventory across 50 chemistries.
Profiling is often combined with die cutting and adhesive lamination in one workflow, so a shaped profile ships as a finished, assembly-ready part. All under an ISO 9001:2015 certified quality management system in Winsted, Connecticut. See the process strip for lead-time and ordering details.
- Custom gasket profiles: dense EPDM and neoprene for high-load flanges; soft BISCO® and PORON® for low-closure-force enclosures
- Edge trim & protective edging: solid rubber, cork, felt, or UHMW selected by wear and friction
- Shaped pads & bumpers: contoured BISCO® and PORON® foam with beveled edges and bonded build-ups
- Skived & made-to-thickness stock: solid rubber and foam brought to a thickness between standard sheet sizes
- Beveled or chamfered edges: dense elastomers hold a crisp bevel; soft foams take a softer, rounded edge
- Holes, slots, or adhesive too: combine profiling with die cutting and lamination in one workflow
Profiling and shaping, converted in-house
Custom profiling and shaping covers the work that goes beyond a flat through-cut: bringing sheet to a precise thickness by skiving, giving a strip a profiled cross-section or a shaped edge, contouring a part to a non-flat outline, and beveling or chamfering edges. H-O performs this fabrication-to-shape in Winsted, then bonds, die-cuts, and laminates the result into a finished part in the same workflow.
What makes the operation different is the depth of the material inventory and the material knowledge behind it. We stock materials from Rogers Corporation, Saint-Gobain, Henkel/Bergquist, DuPont, NeoGraf, Kaneka, Victrex, and dozens of other suppliers, and we maintain shaping parameters for each chemistry, grade, and thickness. When an engineer asks for a skived BISCO® sheet at a target thickness or a beveled-edge EPDM profile, we already know how the material shapes and finishes.
Skiving, profiling, contour cutting, edge beveling, bonding, and finishing are performed in Winsted, CT, and combined with die cutting and adhesive lamination in one workflow. Continuous extruded profiles with a fixed cross-section are a partner-network, made-to-order capability; H-O fabricates profiles by shaping, not by extrusion. Tell us the shape and we will confirm the right route.
Skiving, profiling, edge shaping & contour cutting
Skiving to thickness
Shaving sheet or bun stock down to a target thickness, including thicknesses between standard sheet sizes. Used to bring solid rubber or foam to a dimension the supplier does not stock.
Profiled strip & edge shapes
Strip and edge parts given a defined cross-section or shaped edge: gasket profiles, edge trim, and protective edging cut and finished to the drawing.
Contour & shaped parts
Parts cut and fabricated to a non-flat or shaped outline rather than a simple flat profile, for pads, bumpers, and gaskets that follow a contour.
Beveled & chamfered edges
Angled, beveled, or chamfered edges on solid and foam parts, for sealing geometry, lead-in, or a finished appearance where a square edge will not do.
Built-up & bonded profiles
Multiple layers or sections bonded into a single built-up profile or shaped construction, combining materials or thicknesses that no single sheet provides.
Finished with die cutting & lamination
Profiled and shaped parts taken through die cutting, adhesive lamination, and finishing in the same workflow, so the shape ships as an assembly-ready part.
Method is matched to the material. A dense 60A EPDM profile bevels and finishes cleanly; a soft BISCO® sponge skives to thickness but is handled gently to avoid crushing the cell structure; UHMW and cork shape differently again. Tell us the grade, thickness, and the cross-section or shape you need, and we will confirm the method and parameters at drawing review.
Guidelines that hold shape and finish
Designing parts for profiling and shaping means matching the cross-section, edge, and thickness to the material. Following these rules before drawings are finalized prevents rework; our engineering team reviews every part for manufacturability first.
- Define the cross-section or edge clearly
- Show the profile, bevel angle, or shaped edge on the drawing with dimensions. A clear cross-section is the single most useful thing for quoting a profiled or beveled part accurately.
- Skived thickness and tolerance
- Call out the target thickness and the tolerance that actually matters. Skiving can reach thicknesses between standard sheet sizes; achievable tolerance depends on the material and the thickness, which we confirm at review.
- Bevel and chamfer angle
- Specify the angle and which edges are affected. Dense elastomers hold a crisp bevel; soft foams take a softer, rounded edge, so set the expectation to the material.
- Built-up and bonded constructions
- For layered profiles, give the layer stack, materials, and bond requirements. We select compatible adhesives from the inventory and bond in the same workflow as shaping.
- Plan to combine with die cutting
- If the shaped part also needs holes, slots, or an adhesive backing, say so. Profiling combines with die cutting and lamination in one workflow, which is usually lower cost than separate operations.
- Design file requirements
- DXF or DWG preferred for outlines and profiles; PDF with dimensions and the cross-section for inspection criteria; STEP and IGES accepted for 3D and contour reference. Include material callout and thickness, critical-dimension tolerances, bevel angles, bond and adhesive specs, and quantity expectations.

Custom profiling & shaping questions
Common questions from engineers speccing profiled and shaped parts.
What does custom profiling and shaping include?
Skiving sheet to a target thickness, profiled strip and shaped edges, contour and shaped parts, beveled and chamfered edges, and built-up bonded profiles. It is the fabrication-to-shape work that goes beyond a flat through-cut, and it is usually combined with die cutting and lamination to finish the part.
What is skiving?
Skiving shaves sheet or bun stock down to a target thickness, including thicknesses between standard sheet sizes a supplier does not stock. It is used to bring solid rubber or foam to a needed dimension, either as a finished shaped part or as input to die cutting and lamination. Achievable tolerance depends on the material and thickness.
Can you put a beveled or chamfered edge on a part?
Yes. We bevel and chamfer edges on solid and foam parts for sealing geometry, lead-in, or appearance. Dense elastomers at 60+ Shore A hold a crisp, defined bevel; soft cellular foams take a softer, rounded edge. Specify the angle and which edges are affected on the drawing.
What materials can H-O Products profile and shape?
From the 687+ material inventory: solid silicone, neoprene, and EPDM, BISCO® and PORON® foams, cork and cork-rubber, SAE and pressed felt, and UHMW PE, plus specialty grades such as fluorosilicone, Viton®, and butyl. Dense elastomers bevel and profile crisply; soft foams skive and shape with gentle handling.
Can profiling be combined with die cutting?
Yes, and it usually is. A profiled or skived part that also needs holes, slots, an outline, or an adhesive backing is taken through die cutting and lamination in the same workflow as shaping. Coordinating the operations holds registration and is usually lower cost than running them separately.
