Precision Custom Rubber Gaskets for Demanding Industrial Applications

In industrial environments, the integrity of sealing solutions is paramount for operational efficiency, safety, and longevity of equipment. Custom rubber gaskets are critical components engineered to create a static seal between two mating surfaces, preventing leakage of fluids or gases and protecting against ingress of contaminants. Raj Industries, an ISO 9001 certified manufacturer since 1994, specialises in producing high-performance custom rubber gaskets tailored to specific industrial requirements.

Material Selection for Optimal Performance

The selection of the appropriate rubber compound is fundamental to the performance and durability of an industrial gasket. This choice is dictated by the operational parameters, including temperature range, chemical compatibility, pressure, and mechanical stresses. Raj Industries advises on and processes a comprehensive range of elastomeric materials:

• EPDM (Ethylene Propylene Diene Monomer): Offers excellent resistance to weathering, ozone, UV, and a wide range of dilute acids and alkalis. Suitable for outdoor applications and water systems, with a typical operating temperature range from -40 °C to +120 °C.
• Nitrile (NBR): Known for its superior resistance to petroleum-based oils, fuels, and greases. Commonly used in hydraulic systems, fuel lines, and automotive applications. Effective from -30 °C to +100 °C.
• Viton® (FKM): A high-performance fluorocarbon elastomer providing exceptional resistance to high temperatures (up to +200 °C intermittently), aggressive chemicals, fuels, and oils. Ideal for aerospace, chemical processing, and oil & gas industries.
• Silicone (VMQ): Characterised by its wide temperature range (-60 °C to +230 °C), excellent flexibility, and resistance to ozone and UV. Used extensively in food, medical, and high-temperature sealing applications.
• Neoprene (CR): Offers a good balance of oil, chemical, and weather resistance. Commonly employed in general industrial and marine environments.
• Natural Rubber (NR): Provides excellent tensile strength, abrasion resistance, and dynamic properties. Suitable for applications requiring high elasticity and resilience.

Precision Manufacturing and Customisation Capabilities

Raj Industries leverages advanced manufacturing processes to produce custom rubber gaskets with precise dimensions and consistent quality. Our capabilities include:

• Die Cutting: A cost-effective method for high-volume production of gaskets from sheet materials, ensuring accurate and repeatable profiles.
• Waterjet Cutting: Provides precise, burr-free cuts without tooling costs, ideal for prototypes, small batches, or intricate designs that require tight tolerances (e.g., ±0.2 mm).
• Moulding (Compression & Transfer): Employed for complex 3D gasket designs, often with integrated features or specific cross-sections, providing superior material integrity and performance for critical applications.

Our engineering team works collaboratively with clients to optimise gasket designs, considering factors such as compression set, tensile strength, hardness (Shore A), and specific environmental conditions to ensure the final product meets exact performance criteria.

Quality Assurance and Tooling Management

As an ISO 9001 certified manufacturer, Raj Industries upholds stringent quality control protocols throughout the entire production lifecycle. From incoming raw material inspection to final product verification, every stage is meticulously monitored to ensure compliance with specifications and industry standards. Dimensional accuracy, material properties, and functionality are verified using calibrated equipment.

Furthermore, Raj Industries offers comprehensive managed tooling services. This includes the design, fabrication, maintenance, and storage of proprietary tooling for client-specific gasket designs. This ensures consistency in production, reduces lead times for repeat orders, and protects intellectual property.
