The main body of the 474Z-14-240T Oil Suction is constructed from high-quality aluminum alloy (6061-T6 grade), a material widely used in automotive oil system components for its excellent mechanical properties. 6061-T6 aluminum alloy is chosen for its superior corrosion resistance (critical for withstanding long-term contact with engine oil and moisture), good tensile strength (≥310 MPa), and excellent thermal conductivity, which helps dissipate heat absorbed from the engine oil. Additionally, the aluminum alloy is lightweight, reducing the overall weight of the engine and contributing to the Haima S5’s fuel efficiency (7.3 L/100Km for the 1.6L manual variant).
Key components integrated into the 474Z-14-240T Oil Suction also use premium materials to ensure optimal performance. The oil suction filter screen (installed at the inlet end of the oil suction) is made of high-density stainless steel mesh (304 grade), which offers excellent wear resistance, corrosion resistance, and filtration performance. The stainless steel mesh has a precise pore size (50-60 μm), which effectively filters out metal particles, dirt, and debris from the engine oil, preventing them from entering the oil pump and damaging critical engine components. The filter screen is designed to be durable and easy to clean, ensuring long-term filtration efficiency. The connecting joints and gaskets of the oil suction are made of high-temperature resistant nitrile rubber (NBR), which offers excellent sealing performance, oil resistance, and heat resistance (up to 120°C), preventing oil leakage at the connection points between the oil suction, oil pan, and oil pump.
The manufacturing process of the 474Z-14-240T Oil Suction follows a strict, ISO 9001 and IATF 16949 certified production workflow, combining precision extrusion, CNC machining, surface treatment, and rigorous quality control—consistent with modern automotive lubrication component manufacturing standards. The production process begins with the preparation of raw materials: the 6061-T6 aluminum alloy billets are heated to a temperature of 450-500°C to make them malleable. The heated billets are then extruded using a precision extrusion process to form the basic shape of the oil suction tube, ensuring uniform wall thickness and consistent dimensional accuracy.
After extrusion, the oil suction undergoes a series of precision CNC machining operations to refine its shape and dimensions. The connection ports (for the oil pan and oil pump) are precision-machined to ensure a tight fit with the corresponding components, with a dimensional tolerance of ±0.01 mm. The inlet end of the oil suction is machined to accommodate the stainless steel filter screen, which is press-fitted into place using precision tools to ensure a secure connection. The surface of the aluminum alloy body is then treated with anodization, a process that forms a protective oxide layer on the surface, enhancing corrosion resistance and preventing oxidation caused by long-term contact with engine oil and moisture. The anodized surface also improves the oil suction’s appearance and durability.
The final step involves the assembly of the filter screen and gaskets, which are installed using precision tools to ensure proper alignment and sealing. Before packaging and delivery, each 474Z-14-240T Oil Suction undergoes a series of rigorous quality inspections, including dimensional accuracy testing, pressure testing, filtration efficiency testing, and leakage testing. Dimensional accuracy testing verifies that all critical dimensions (tube length, connection port diameter, wall thickness) match Haima’s original specifications. Pressure testing involves subjecting the oil suction to a pressure of 0.3-0.5 MPa to ensure it can withstand the operating pressure of the engine’s lubrication system without deformation or leakage. Filtration efficiency testing verifies that the filter screen effectively filters out particles of the specified size.
