Custom Oil Filter Housing Manufacturer
Oil Filter Housing
China Simis Company is a specialized OEM custom casting manufacturer of high-integrity Oil Filter Housings (or Oil Cooler Module Housings). This critical component manages the flow of lubricating oil through the filter and often integrates passages for oil cooling and temperature regulation. It is a fundamental part of the engine's lubrication and thermal management system.
Oil Filter Housings are subjected to high internal pressure (filtration pressure), cyclical fatigue, thermal stress from hot oil and coolants, and corrosion from chemical additives. We utilize precision casting processes to produce durable, leak-proof housings from Aluminum Alloy, Stainless Steel, and Cast Iron, ensuring superior pressure capacity, long-term fatigue resistance, and effective thermal regulation.
What Are the Manufacturing Processes for Oil Filter Housing?
The casting process must deliver a component that is structurally sound and free from porosity to withstand high operating pressure and maintain a perfect seal. We mainly adopt 4 core processes including High/Low Pressure Die Casting, Sand Casting/Shell Mold Casting, Investment Casting and Vacuum Impregnation to meet different oil filter housing production needs.
| Manufacturing Process | Material Focus | Component Type & Key Advantage |
| High/Low Pressure Die Casting | Aluminum Alloy (A380 series, or specialized pressure-tight alloys). | High-Volume Automotive & Compressor Housings; provides excellent lightweighting, good surface finish, and minimal porosity for pressure integrity when using controlled casting techniques. |
| Sand Casting / Shell Mold Casting | Cast Iron, Steel Alloy. | Heavy-Duty Industrial, Marine, and Generator Housings; cost-effective for larger sizes and capable of handling extremely high-pressure surges. |
| Investment Casting | Stainless Steel. | Used for specialty High-Corrosion or High-Temperature applications where maximum precision and internal soundness are required (e.g., aerospace or severe marine). |
| Vacuum Impregnation | Aluminum Alloy. | Often used after casting to seal any residual microporosity, ensuring the housing is absolutely pressure-tight for critical automotive/marine applications. |
How to Select Oil Filter Housing Materials?
Material selection is driven by the required working pressure, the operating temperature range, and the need to resist oil and coolant additives. We provide 3 main material types including Aluminum Alloy, Stainless Steel and Cast Iron/Steel Alloy for oil filter housing production, each with specific performance advantages.
| Material Type | Primary Performance Requirement | Typical Oil Filter Housing Application |
| Aluminum Alloy (Cast) | Lightweighting, superior thermal conductivity, and good machinability. | Modern automotive engines and compressors where weight and heat exchange efficiency are critical. |
| Stainless Steel | Maximum corrosion resistance against aggressive coolants, chemical additives, and saltwater environments. | Marine engines and specialized industrial chemical equipment. |
| Cast Iron / Steel Alloy | Highest strength and pressure resistance; excellent fatigue life. | Heavy trucks, generators, and high-pressure hydraulic systems. |
| Vacuum Integrity | Minimal Porosity. | All materials must guarantee integrity under high-pressure differential to prevent oil leakage and ensure proper filtration bypass function. |
What Measures Ensure Precision Machining and Quality Assurance for Oil Filter Housings?
Precision machining is vital to ensure the correct function of internal valves (bypass valve, anti-drain back valve) and to guarantee the external sealing surfaces are perfectly flat. Our core quality assurance measures include sealing surface flatness control, internal valve bore precision machining, pressure testing and non-destructive testing (NDT).
·Sealing Surface Flatness:
Precision CNC machining of all gasket interfaces and mounting flanges is critical to prevent oil and coolant leaks, meeting standards for sealing roughness (Ra value).
·Internal Valve Bores:
Machining of internal bores for the filter element, bypass valve, and anti-drain back valve must be held to tight tolerances to ensure proper filter operation and flow control.
·Pressure Testing:
Housings undergo mandatory leak testing (using air pressure decay or hydrostatic pressure testing) to certify the component's burst strength and sealing integrity under simulated operating conditions.
·Non-Destructive Testing (NDT):
Utilizing X-ray inspection on critical aluminum castings to verify internal integrity and confirm the absence of porosity in the thinnest wall sections, especially around cooling passages.
What Are the Key Applications for Simis Custom Oil Filter Housings?
Our custom-cast housings are integral to the lubrication and cooling of high-performance machinery. The main application fields include Automotive, Industrial Equipment and Marine & Generators.
·Automotive:
Integrating the oil filter, oil cooler, and sometimes the pressure switch into a single module for compact thermal management.
·Industrial Equipment:
Large-scale housings for compressors, hydraulic systems, and heavy industrial gearboxes.
·Marine & Generators:
Housings requiring stainless steel or heavy-duty cast iron for durability in harsh, continuous-operation environments.
