40μm Sintered Copper Cup Filter For Hydraulic Lubrication

This sintered copper filter features a cup-shaped design, manufactured from red copper powder through a high-temperature sintering process that forms a uniform, controlled depth filtration matrix. In contrast to conventional wire mesh media, its monolithic sintered structure delivers superior compressive strength and resistance to pressure surges, ensuring structural integrity under fluctuating hydraulic system conditions and eliminating the risk of secondary contamination caused by mesh rupture. The compact cup-shaped geometry enables embedded installation within confined spaces such as valve stacks and line connections, offering greater flexibility for system integration.

In hydraulic return line and lubrication system applications, this filter serves as a critical protective component, primarily tasked with retaining solid particulates and colloidal contaminants generated by component wear, external ingress, or fluid degradation. Effective contaminant control significantly reduces the risk of valve spool sticking, pump wear, and lubrication point failure, thereby extending equipment maintenance intervals. This filter is widely deployed in injection molding machines, presses, and mobile machinery where high system cleanliness is required, delivering reliable filtration performance under demanding, continuous-duty conditions.

Products features

Preserves Lubrication Film Integrity

 

Consistently removes fine particulates that could disrupt the formation of stable lubrication films, maintaining consistent contact conditions between friction surfaces and reducing abnormal wear.

 

Accommodates Cold Start Flow Conditions

Designed to manage transient high-flow conditions during cold start when fluid viscosity is elevated, ensuring unrestricted flow without pressure lag or supply interruption.

 

 

Resists Degradation in Recirculating Oil Systems

 

Constructed from materials that withstand prolonged exposure to oxidized oil and accumulated varnish, maintaining structural integrity and filtration performance over extended service intervals.

Simplifies System Integration

Cup-shaped geometry aligns with standard interface dimensions, enabling direct installation into existing hydraulic and lubrication circuits with minimal additional fittings or layout modifications.

 

Extends Critical Component Service Life

 

Maintains fluid cleanliness to reduce wear rates in pumps, valves, and bearings, allowing component replacement intervals to align more closely with filter maintenance schedules.

Performs Under Continuous Heavy-Duty Cycle

Delivers stable filtration performance in high-intensity applications such as injection molding, pressing, and mobile equipment, supporting extended runtime with minimal unplanned downtime.

 

Products Applications

Return Line Filtration for Injection Molding Machine Hydraulic Systems
Installed at the return line terminal to capture metallic wear particles generated during frequent directional changes, preventing contaminants from re-entering the tank and recirculating through the system.

Centralized Lubrication Systems for Presses
Serves as a final-stage filter upstream of critical lubrication points, ensuring oil entering heavy-duty bearings and guideways maintains cleanliness to reduce the risk of premature wear or failure.

Travel Hydraulic Systems in Mobile Machinery
Deployed in return lines for travel circuits, withstanding high-frequency vibration and pressure surges to maintain reliable performance of travel motors and control valve assemblies.

Circulating Lubrication Systems in Metallurgical Equipment
Performs reliably under elevated temperatures where oil is subject to extended oxidation, tolerating accumulated sludge and varnish while extending oil change intervals.

Pneumatic-Hydraulic Combination Units for Injection Molding Machine Robots
Installed on the return side of hydraulic units, with cup-shaped geometry suited for compact cabinet layouts, facilitating centralized maintenance and rapid changeouts.

Gearbox Lubrication Systems for Wind Turbines
Installed in gearbox return lines, performing consistently across a wide temperature range from cold startup to sustained high-temperature operation under variable speed and load conditions.
