Custom Silicone Washer Manufacturer
As a premier custom silicone washer manufacturer and supplier, Temco Rubber specializes in the engineering and high-volume production of precision elastomeric components. We manufacture custom silicone washers for demanding sealing, insulation, spacing and vibration-control applications according to your drawings, samples and technical specifications.
Custom Molded Silicone Washers & Specifications
While many suppliers focus primarily on standard die-cut components, Temco Rubber specializes in the production of custom molded silicone washers. Molding allows engineers to move beyond simple flat profiles and introduce radii, chamfers, sealing ribs, stepped sections and varying wall thicknesses.
This capability is particularly important when a conventional flat washer cannot generate the required sealing force, electrical isolation or mechanical interlocking within an assembly.
By combining precision manufacturing with our silicone mold tooling capabilities , we can develop washers around your exact application rather than forcing your product to accommodate a standard component.
Custom Manufacturing Capabilities
Miniature precision washers through large industrial sealing components.
Different levels of flexibility, compression and load-bearing capacity.
Flat, stepped, flanged, countersunk and grooved washer geometries.
High-tear, low-compression-set and conductive formulations.
Custom Silicone Washer Types
We manufacture standard and complex washer geometries according to customer drawings, CAD data, samples, dimensions and application requirements.
Flat Silicone Washers
Precision circular washers for sealing, spacing, vibration isolation and electrical insulation applications.
Stepped Washers
Multi-level molded profiles designed to locate components, distribute load and create controlled sealing interfaces.
Flanged Washers
Molded flanges provide additional locating, retention and sealing functionality in mechanical assemblies.
Grooved & Complex Profiles
Custom molded geometries featuring ribs, grooves, chamfers and application-specific sealing surfaces.
High-Performance Silicone Rubber Washers
Silicone rubber combines thermal stability, elasticity, electrical insulation and environmental resistance, making it suitable for demanding industrial washer applications.
Electrical Insulation & Damping
Silicone washers can function as dielectric insulating washers between fasteners, electronic assemblies and conductive surfaces. Their elastomeric structure also helps absorb vibration and mechanical shock that could otherwise fatigue sensitive components.
Fluid & Gas Sealing
Custom silicone sealing washers create controlled sealing force between mating surfaces. Silicone's elastic recovery and low compression set make it particularly useful where sealing performance must remain stable through repeated thermal cycles.
Food & Sanitary Applications
FDA-compliant silicone grades can be specified for food, beverage, sanitary and medical applications requiring clean, odorless and heat-resistant sealing components capable of repeated high-temperature sterilization.
Silicone Washer Applications
Custom silicone washers can perform multiple functions within industrial equipment, electrical systems and OEM assemblies.
Electronics & Telecommunications
Electrical isolation, vibration damping and protection of circuit boards, enclosures, fasteners and sensitive electronic hardware.
Industrial Valves & Fluid Systems
Static sealing interfaces used in plumbing equipment, industrial valves, manifolds and fluid-handling assemblies.
Automotive & Aerospace Assemblies
Temperature-resistant washers for vibration-prone assemblies, electrical hardware and components exposed to thermal cycling.
Food, Beverage & Medical Equipment
Application-specific silicone formulations for equipment requiring hygienic sealing, heat resistance and repeated cleaning or sterilization cycles.
Precision Silicone Washer Manufacturing Process
Our process is engineered around repeatability, dimensional control and efficient scaling from prototype development to high-volume production.
1. Engineering & Tooling Development
Part geometry, ID, OD, thickness, tolerances, material requirements and annual production volume are reviewed before developing the appropriate mold configuration.
2. Multi-Cavity Mold Production
Multi-cavity tooling can be developed for high-volume projects, increasing production output while reducing per-part manufacturing cost.
3. Controlled Silicone Molding
Temperature, pressure and curing parameters are controlled throughout the molding cycle to achieve consistent polymer cross-linking and repeatable physical properties.
4. Inspection & Post-Curing
Dimensional inspection focuses on critical characteristics including Inner Diameter, Outer Diameter and Thickness. Post-curing can also be applied where the application requires additional material stabilization.
Custom Washer Specifications
Washer specifications can be customized based on your assembly design, operating conditions and performance requirements.
