Advanced Manufacturing Process Flow

The manufacturing of a reliable oil pressure sensor filter screen is a multi-stage process that combines material science with precision engineering. The objective is to produce filters with consistent pore size, high mechanical strength, and exceptional durability.

Process Flow Schematic:

1. Material Procurement & Inspection: High-grade raw materials, primarily stainless steel alloys (e.g., 304, 316L), are sourced from certified suppliers. Each batch undergoes rigorous inspection for chemical composition, mechanical properties, and surface finish to ensure compliance with international standards (e.g., ASTM, DIN).
2. Wire Drawing & Weaving/Sintering:
   • For woven mesh, wires are drawn to precise diameters and then woven on advanced looms to create a uniform mesh with controlled pore sizes.
   • For sintered filters, metal powders are compacted and then heated (sintered) to bond the particles, creating a porous, robust structure with specific filtration ratings.
3. Cutting & Forming (CNC Machining): The raw mesh or sintered sheet is then precisely cut and formed into the desired shape and dimensions. This often involves advanced CNC machining to achieve tight tolerances required for sensor integration. This stage is crucial for creating the specific geometry of the oil pressure sensor screen filter.
4. Welding & Assembly: Individual filter components (e.g., mesh disc, support rings, housing) are assembled and joined using precision welding techniques such as laser welding or TIG welding. These methods ensure strong, leak-proof joints without compromising the filter media's integrity.
5. Cleaning & Surface Treatment: Filters undergo thorough cleaning processes, including ultrasonic cleaning, to remove any manufacturing residues, oils, or contaminants. Specialized surface treatments (e.g., passivation) may be applied to enhance corrosion resistance and biocompatibility.
6. Quality Control & Testing: Each filter is subjected to a battery of tests to verify performance and compliance. These include:
   • Bubble Point Test: To confirm the largest pore size.
   • Flow Rate/Pressure Drop Test: To ensure minimal restriction at specified flow rates.
   • Dimensional Inspection: Using optical comparators and CMMs for precise measurements.
   • Burst Strength Test: To verify mechanical integrity under extreme pressure.
   • Material Certification: Verification against ISO, ANSI, and customer-specific standards.
   This ensures the filter screen's reliability and extended service life, contributing to energy saving by maintaining system efficiency and offering superior corrosion resistance inherent in the stainless steel composition.
7. Packaging & Shipping: Filters are carefully packaged to prevent damage during transit, often with protective coatings or sterile packaging for specific applications.

This meticulous process, from raw material to final product, ensures that each filter screen meets stringent quality benchmarks, making them suitable for demanding target industries like petrochemicals, metallurgy, and water supply & drainage, where corrosion resistance and precise filtration are critical.
