Custom Silicone Gaskets Manufacturer
NEWTOP manufactures custom silicone gaskets, rubber gaskets and sealing components for industrial equipment, electronics, medical devices, food-contact products, appliances and custom assemblies. We support die-cut, molded, conductive, food-grade and project-specific gasket production.
Silicone Gaskets We Can Produce
We support both simple flat gaskets and complex custom molded gasket parts that require accurate shape, reliable compression and stable sealing performance.
Built Around Your Sealing Surface and Assembly Structure
A gasket project needs more than a basic shape. We review the sealing surface, compression area, groove structure, screw holes, cutouts, material hardness, operating temperature and contact environment before production.
For flat gasket parts, sheet-based sealing, insulation and cushioning applications.
For 3D sealing structures, lips, grooves, raised edges and complex profiles.
For EMI shielding, electrical protection, enclosure sealing and electronic devices.
For food-contact, medical device and clean-use sealing applications.

Why Work With NEWTOP for Silicone Gaskets?
Gasket projects require stable dimensions, reliable material performance, clean edges and repeatable sealing quality. Our factory support is built around these requirements.
Gasket Manufacturing Experience
We support die-cut, molded, conductive, food-grade and custom gasket projects.
Tooling and Structure Review
We review gasket geometry, holes, sealing lips, parting line and molding feasibility before tooling.
Process Matching
Die cutting, compression molding, injection molding and secondary processing can be selected by project.
Factory-Direct Production
Direct production helps control sampling, mold adjustment, batch schedule and repeat order consistency.
Inspection and Records
Inspection can cover dimensions, material, surface, edge quality, hardness and approved sample records.
Repeat Supply Stability
Mold records, material records, color standards and inspection requirements are kept for repeat production.
Handling Complex Silicone Gasket Structures From Design to Production
Not every gasket is a simple flat part. For projects with sealing lips, raised edges, grooves, irregular outlines, screw holes, embedded functions or tight assembly requirements, we review the structure first and choose the most suitable production route.
- Structure feasibility review: evaluate gasket thickness, sealing lip, groove fit, hole position, undercut risk and assembly direction before tooling.
- Molding process selection: use compression molding, silicone injection molding or overmolding according to gasket structure, quantity and performance requirements.
- Complex demand handling: support irregular shapes, multi-hole layouts, frame gaskets, conductive silicone gaskets, food-grade parts and medical-grade sealing components.
- Secondary process planning: arrange trimming, punching, surface treatment, adhesive backing, color coding or packaging steps when the project requires it.
Key Quality Points We Control
Silicone gaskets are small sealing parts, but their accuracy and material consistency directly affect assembly and sealing performance.
Dimensional Accuracy
Check outline, hole position, thickness, cutouts, tolerance and fit consistency.
Material Confirmation
Confirm material, hardness, color, grade and application-specific requirements.
Edge & Surface Finish
Control flash, burrs, deformation, surface marks, color difference and visible defects.
Compression Consistency
Maintain approved samples, mold records, material records and inspection standards.
