ULTRA-DETAILED PRODUCT ENGINEERING
Dimensional Precision & Tolerance Control
RUBBER-KU rubber washers are engineered with tight dimensional tolerances to ensure consistent sealing performance:
- Inner Diameter (ID): Precision-fit for bolts, screws, and shafts
- Outer Diameter (OD): Optimized for load distribution and sealing area
- Thickness: Controlled for compression efficiency and sealing pressure
- Tolerance Range: ±0.05mm to ±0.20mm depending on application
We support custom geometry designs, including:
- Flat washers
- Beveled washers
- Stepped washers
- Bonded sealing washers
- Insert-molded metal-rubber washers
Mechanical & Physical Performance Properties
Compression Set Resistance
- Ensures washer returns to original shape after compression
- Critical for long-term sealing reliability
- Low compression set = longer service life
Tensile Strength & Elongation
- High tensile strength prevents tearing under stress
- Excellent elongation allows flexibility during installation
Hardness Range (Shore A)
- Soft (30–40 Shore A): High flexibility for delicate sealing
- Medium (50–70 Shore A): Balanced sealing and durability
- Hard (70–90 Shore A): High-pressure and structural applications
Abrasion & Wear Resistance
- Maintains integrity under friction and repeated use
- Ideal for dynamic and moving assemblies
THERMAL & CHEMICAL RESISTANCE PERFORMANCE
Temperature Resistance by Material
- EPDM: -40°C to +120°C
- NBR: -30°C to +110°C
- Neoprene: -35°C to +110°C
- Viton (FKM): -20°C to +250°C
Chemical Compatibility
- EPDM: Water, steam, mild chemicals
- NBR: Oils, fuels, hydraulic fluids
- Neoprene: Refrigerants, moderate chemicals
- Viton: Aggressive chemicals, acids, solvents
Environmental Resistance
- UV-resistant (EPDM & Neoprene)
- Ozone-resistant
- Weatherproof and oxidation-resistant
SUPER-DETAILED MANUFACTURING PROCESS
1. Raw Material Selection & Polymer Engineering
- Selection of base elastomer depending on application
- Addition of:
- Fillers (carbon black, silica) for strength
- Plasticizers for flexibility
- Accelerators for curing efficiency
- Anti-aging agents for durability
2. Internal Mixing (Banbury Mixing Process)
- High-shear mixing ensures homogeneous compound
- Temperature-controlled blending
- Uniform dispersion of additives for consistent quality
3. Milling & Sheet Formation
- Rubber compound processed into sheets
- Thickness calibrated for precise washer production
- Surface conditioning for molding consistency
4. Precision Molding Technologies
Compression Molding
- Ideal for thick or high-strength washers
- Uniform pressure distribution
Injection Molding
- High-speed production for complex designs
- Excellent dimensional repeatability
Transfer Molding
- Suitable for bonded or insert washers
5. Vulcanization (Curing Process)
- Cross-linking of polymer chains under heat and pressure
- Enhances:
- Elasticity
- Mechanical strength
- Heat resistance
- Chemical stability
6. Die Cutting & CNC Finishing
- High-precision die cutting for flat washers
- CNC trimming for complex geometries
- Burr-free edges for perfect sealing contact
7. Surface Treatment & Coating (Optional)
- Anti-stick coatings
- PTFE coating for reduced friction
- Oil-resistant surface finishing
- Color coding for identification
