Stainless Steel Fixed Base Precision Lost Wax Investment Casting Parts

Marine machinery casting parts are robust components specifically designed to withstand the extreme conditions of maritime operations. Manufactured through advanced sand casting and investment casting processes, these parts utilize corrosion-resistant materials like naval brass, duplex stainless steel, and nickel-aluminum bronze. They are engineered to resist saltwater corrosion, biofouling, and constant vibration while maintaining structural integrity in demanding marine applications. These critical components ensure reliable performance in propulsion systems, deck machinery, and offshore equipment across commercial and naval fleets.

Core Processing & Customization Services

Specialized Casting Technology

Our Stainless Steel Fixed Base is a premium precision lost wax investment casting part engineered for marine machinery. The core manufacturing process combines silica sol investment casting with high-precision CNC machining. This process is optimized for marine operating conditions. The casting stage creates robust, complex structures that resist saltwater corrosion and constant vibration. The CNC machining step achieves tight tolerances of CT4–CT7 and a surface roughness of Ra1.6–Ra6.3. We select materials based on marine durability needs. The materials include duplex stainless steel, naval brass and nickel-aluminum bronze. These materials prevent pitting and crevice corrosion in seawater environments.

Tailored OEM Solutions

We offer customized OEM investment casting & CNC machining services for marine equipment manufacturers. Our team supports custom design adjustments for fixed base dimensions, mounting hole positions and load-bearing capacities. We use design software such as Solidworks and AutoCAD. We accept file formats like STP, XT and PDF for seamless design collaboration. Surface finishing options are tailored to marine needs. They include black oxide coating and anti-biofouling treatments. These treatments inhibit marine organism growth on submerged components. We can produce parts ranging from 1g to 30kg. We accommodate both prototype development and mass production for commercial and naval fleet applications.

Core Advantages & Application Scenarios

Unique Marine-Grade Advantages

This stainless steel fixed base delivers three marine-specific benefits. First, it has superior corrosion resistance. Special alloy compositions and protective coatings prevent saltwater erosion. This extends service life in offshore environments. Second, it offers exceptional impact resistance. Its tough material properties withstand wave impacts and collision forces in rough sea conditions. Third, it has built-in biofouling prevention. Copper-based alloy options naturally deter marine organism attachment. This reduces maintenance frequency for submerged equipment.

Marine-Specific Application Areas

The fixed base is a critical component for various maritime systems. In propulsion systems, it serves as a stable mounting component for propeller hubs and shaft brackets. It endures high thrust loads and constant seawater exposure. In deck machinery, it supports windlass components and winch drums under heavy mechanical stress. In offshore platform equipment, it is integrated into pump housings and valve bodies for oil rigs and floating production units. It also applies to ship engine cooling systems and deep-sea mining machinery. It provides reliable structural support in extreme marine environments.

Quality Assurance

Marine Industry Compliance

Our marine machinery casting parts hold ISO9001:2015 and SGS certifications. They comply with strict maritime industry standards such as BS, DIN and JIS. The non-standard product design meets the unique technical requirements of marine equipment. It adheres to global regulatory benchmarks for offshore operations.

Targeted Durability Testing

We conduct marine-focused quality tests to ensure product reliability. We perform salt spray corrosion tests to verify resistance to seawater exposure. We carry out vibration tests to simulate long-term maritime operational conditions. We also conduct dimensional accuracy checks after machining and heat treatment. The heat treatment processes include normalizing and carburizing. Every batch of fixed bases undergoes rigorous inspection. This guarantees consistent performance in the harsh marine environment.
