Product Description
Material Selection and Formulation
The performance of a rubber mounting is fundamentally determined by its elastomer compound. We do not rely on a single universal material; instead, we formulate compounds based on the operational demands of the end product. Our standard material portfolio includes:
Natural Rubber (NR): Selected for applications requiring high elasticity, good fatigue resistance, and effective low-frequency vibration isolation. It is suitable for general-purpose industrial mounts.
Nitrile Rubber (NBR): Formulated for environments where exposure to oils, fuels, or hydraulic fluids is present. NBR maintains its physical properties and dimensional stability in petroleum-based media.
Ethylene Propylene Diene Monomer (EPDM): Utilized for outdoor or high-temperature applications due to its superior resistance to ozone, UV radiation, and weathering. It is commonly specified for HVAC systems and exterior architectural mounts.
Silicone (VMQ): Chosen for extreme temperature ranges, from cryogenic conditions to continuous high-heat exposure, while maintaining flexibility and electrical insulation properties.
Polyurethane (PU): Deployed when higher load-bearing capacity and abrasion resistance are required compared to standard elastomers. PU mounts offer a higher durometer range and resistance to tearing.
Each compound is compounded in-house, allowing us to adjust parameters such as durometer (hardness), tensile strength, elongation at break, and compression set to match the client's technical data sheet.
Manufacturing Processes and Customization
Our facility supports multiple molding and fabrication techniques to accommodate varying geometries and production volumes.
Compression and Transfer Molding: Used for high-volume production of standard and semi-custom mounts. Metal inserts, if required, are pre-treated with adhesive bonding agents and placed into the mold prior to vulcanization to ensure a permanent rubber-to-metal bond.
Injection Molding: Applied for complex geometries, tight tolerances, and parts requiring consistent flash-free finishes. This process is ideal for precision anti-vibration dampers used in automotive and electronics sectors.
CNC Machining and Die Cutting: For prototyping, low-volume runs, or non-moldable profiles, we utilize CNC machining and die-cutting to produce rubber blocks, strips, and gaskets from cured slabs. This allows for rapid iteration without the lead time associated with mold fabrication.
Bonding Technology: We offer rubber-to-metal bonding using chemically treated inserts and structural adhesives. This is critical for mounts that must withstand significant shear and compressive loads without delamination.
Customization extends beyond geometry. We can integrate threaded inserts, tapped holes, slotted mounting patterns, and specific surface textures directly into the molding process.
Functional Purpose and Performance Parameters
The primary function of our rubber mountings is to decouple a vibrating source from its supporting structure. This serves three engineering objectives:
Vibration Isolation: By introducing a flexible element with a specific natural frequency below the disturbing frequency, we reduce the transmission of vibratory forces. This protects sensitive equipment and prevents structural fatigue.
Shock Absorption: Bumpers and buffers are designed to absorb kinetic energy during impact events, such as the closing of heavy doors, machinery stops, or transport shocks. The hysteresis of the rubber compound converts kinetic energy into heat.
Noise Reduction: Structure-borne noise is attenuated as vibrational energy is dissipated within the elastomer, reducing the acoustic footprint of mechanical systems.
Key performance parameters we control during production include static and dynamic stiffness, damping ratio, creep resistance, and load-deflection characteristics. All production batches undergo quality control testing to verify dimensional accuracy and durometer consistency.
Application Scenarios
Our OEM rubber mountings are integrated into a wide range of industrial and commercial systems:
Industrial Machinery: Motor mounts, pump bases, compressor feet, and generator isolators. These applications typically require oil-resistant compounds and high-load capacity.
HVAC and Building Services: Fan coil units, air handling units, and chiller mounts. EPDM or neoprene compounds are standard here to withstand outdoor exposure and moderate temperatures.
Automotive and Transportation: Engine mounts, suspension bumpers, cab isolators, and exhaust hangers. These parts demand high durability, temperature cycling resistance, and precise dynamic stiffness.
Consumer Electronics and Appliances: Washing machine dampers, printer feet, and server rack isolators. Precision molding and low-compression set are critical to maintain leveling and prevent resonance.
Marine and Offshore: Engine and generator mounts exposed to saltwater, fuel, and constant dynamic loading. Specialized compounds are formulated to resist hydrolysis and marine biofouling.
We operate as a technical partner rather than a catalog supplier. The OEM process begins with a review of the client's CAD models, load specifications, and environmental parameters. If an existing mold does not meet the requirement, our engineering team will design a custom tooling solution. Prototypes are produced for fit-check and functional validation before full-scale production is authorized.
We maintain traceability of raw material batches and process parameters for each production run, ensuring consistency across shipments. Our facility is equipped to handle both short-run custom jobs and long-term volume supply agreements, with flexible scheduling to accommodate just-in-time delivery requirements.
