Industrial Components
Custom molded and extruded rubber and plastic parts for industrial components applications – built to your print, or designed with you.
Rubber and plastic applications in industrial equipment
COi Rubber manufactures custom molded and extruded rubber and plastic industrial components across transit, construction, recreation, appliance, power tools, HVAC and heavy equipment. We make it our business to learn your business – providing application, material and assembly assistance – and build to your print, or help design the part from the requirement up.
Below are common rubber and plastic applications our customers source in this industry, and the materials we mold for them. These are engineering considerations, not guarantees of suitability – final selection depends on your drawing, operating environment and testing. Send a drawing or a sample part and we will match the compound, durometer and process to the application.
Applications:
- Bellows (rubber) – protect moving joints in transit and machinery.
- Door, window and glazing seals (rubber) – seal enclosures, elevator doors, cabs and panels against weather and dust.
- Grommets and anti-vibration mounts (rubber) – refrigeration compressor grommets, panel grommets and isolation mounts for HVAC and equipment.
- Rubber-to-metal bonded assemblies (rubber or rubber-metal assemblies) – bonded parts that add strength and vibration control in appliances and machinery.
- Bumpers, pads and stops (rubber) – sweeper bumpers, shock mounts, bumper pads and marine bumpers.
- Sanding pads and wear parts (rubber) – pads, core protectors and wear surfaces for power tools and equipment.
- Plastic housings, spacers and trim (plastic) – molded or extruded plastic components where insulation, weight or cosmetics call for polymer instead of metal.

Materials and your RFQ
Industrial components range from small seals to large bonded assemblies. EPDM serves weather and water exposure, polychloroprene (CR) balances oil and ozone resistance, natural rubber and SBR suit abrasion and cost-driven parts, silicone serves heat, and FKM serves chemical and fuel contact. Process follows the part: molding, extrusion, insert molding or rubber-to-metal bonding.
When you request a part, tell us the temperature range, media or chemical exposure, and expected service life, and include the drawing or a sample part. We match the compound and durometer to that.
Design considerations for industrial components
The right compound depends on the conditions the part will live in. The points below shape material and geometry choices for industrial applications:
- Sealing. Door, window, glazing and panel seals keep weather and dust out of enclosures, cabs and machinery; profile and compression follow the gap.
- Vibration. Compressor grommets and isolation mounts for HVAC and equipment trade damping against stability; they are sized from the load and the frequencies involved.
- Bonded assemblies. Where a part must seal and fasten in one piece, rubber-to-metal bonding adds strength and vibration control in a single component.
- Wear and abrasion. Bumpers, pads, stops and sanding pads are wear parts; compound and thickness follow the surface and the duty.
- Media and temperature. Exposure varies widely across transit, construction, appliance, power tools and heavy equipment – list what the part will contact and its temperature range.
- Process fit. Molding, extrusion, insert molding or bonding follows the part geometry and volume; we recommend the process with the quote.
These are engineering considerations to review together at the quoting stage, not guarantees of suitability for a specific application.
Molding and extrusion for industrial components
We match the process to the part and the volume:
- Rubber molding – compression, transfer and injection molding for bellows, seals, grommets, mounts, bumpers and pads, from prototype quantities through production runs.
- Plastic molding and extrusion – injection-molded housings, spacers and trim, plus extruded profiles where the cross-section is constant.
- Bonded assemblies – rubber bonded to metal or plastic inserts where the part must seal and fasten in one piece.
Send a drawing or a sample part and we will recommend the process, tooling approach and compound together.
From prototype to production
Every new part goes through first article inspection or a Level 1 PPAP (Production Part Approval Process) before production – Level 3 for automotive, Level 4 for higher-requirement projects. We provide material certifications verified in our own lab against your material requirements, plus a dimensional layout, a bubble blueprint and a signed first article form. Level 3 goes into full industry-standard PPAP documentation depth: design records, process flow, PFMEA, control plan, MSA, capability studies (CPK) and the Part Submission Warrant (PSW). Higher-requirement projects can run customer-defined Level 4 submissions where specified. Our manufacturing facility is IATF 16949 certified, with APQP and 5-Why and fishbone root-cause analysis built into our quality process. Once a part is approved, we hold the compound, durometer and tooling consistent so reorders match the approved part.
What to include in your RFQ
A complete RFQ gets a faster, more accurate quote. Include what you can from this list:
- Drawing or sample part (2D or 3D files welcome)
- Prototype and annual quantities
- Operating environment: temperature range, media exposure
- Any required standard or rating (for example a flammability rating)
- Tolerance and fit requirements, including mating surfaces
- Target timeline for samples and production
Send these to sales@coirubber.com and we will respond with material and process recommendations.
