Custom Case Study: Sintered Titanium robs for Spanish Clients

Filtration solutions meeting 0.1-micron precision requirements elevate product purity for Spanish pharmaceutical enterprises.

Recently, Guangzhou Liyuan Water Purification Equipment Co., Ltd. successfully completed a custom order for high-performance sintered titanium core filter cartridges for a Spanish client. These specially-specified cartridges (φ75×250mm, 0.1μm filtration precision, 250 units) will be deployed in the client's European pharmaceutical production line.

Project Background and Client Requirements

The Spanish client specializes in high-end pharmaceuticals and requires precision filtration of pharmaceutical solutions during production. Their previously used filter cartridges suffered from insufficient filtration precision and deformation issues, impacting production efficiency and product quality.

The client specified highly detailed technical requirements:

• Cartridge Dimensions: 75mm diameter, 250mm length excluding fittings
• Filtration Precision: 0.1 micron (extremely high precision requirement)
• Connector Configuration: Custom connectors incorporating tension rod structures
• Quantity: 250 units

Notably, the 0.1-micron filtration precision falls within an extremely high-precision range, posing significant challenges to the cartridge manufacturing process.

Solution and Technical Details

Facing this demanding order, Filter Source's technical team responded swiftly, developing a detailed technical solution.

Material Selection and Manufacturing Process

Filter Source utilizes high-purity titanium metal powder (purity ≥99.7%) as raw material, manufactured through advanced powder metallurgy techniques. Titanium filter elements are renowned for their excellent chemical stability, resistance to acid/alkali corrosion, and high-temperature tolerance, making them particularly suitable for the pharmaceutical industry.

The manufacturing process involves sieving, cold isostatic pressing, followed by sintering under high-temperature and high-vacuum conditions. This technique ensures the filter element possesses uniform pore size distribution and stable pore geometry, guaranteeing consistent and reliable filtration performance.

Custom Dimensions and Connection Design

The requested φ75mm diameter represents a non-standard size (standard diameters typically include Ф22mm, Ф30mm, Ф50mm, etc.). Our engineering team custom-designed the mold and manufacturing process according to client specifications, guaranteeing precise dimensional accuracy.

The connection incorporates a tension rod structure, a design that enhances the cartridge's mechanical strength, preventing deformation or damage under pressure fluctuations. The tension rod enables the cartridge to withstand higher pressure differentials (maximum working differential pressure up to 0.6 MPa), extending its service life.

Overcoming the 0.1 Micron Precision Challenge

The 0.1-micron filtration precision requirement far exceeds conventional titanium filter cartridges (typically 0.22-100 microns). To achieve this, we optimized the particle size distribution of titanium powder and sintering process parameters. By precisely controlling sintering temperature and holding time, we ensured the cartridges exhibit narrower pore size distribution and higher separation efficiency.

Product Advantages and Performance Features

This custom titanium core filter series offers the following distinct advantages:

1. Exceptional Filtration Precision: 0.1-micron filtration effectively removes minute particulates and microorganisms from pharmaceutical solutions, guaranteeing product quality.
2. Superior Corrosion Resistance: Titanium's inherent corrosion resistance enables operation in harsh environments including strong acids and alkalis (pH 2-12).
3. High-Temperature Resistance: Withstands operating temperatures up to 280°C (wet state), fully meeting pharmaceutical industry requirements for high-temperature sterilization.
4. Zero Particle Shedding: Complies with food hygiene and pharmaceutical GMP standards, preventing secondary contamination of the original solution.
5. Extended Service Life: Capable of online regeneration and easy cleaning, offering significantly longer lifespan than conventional membrane filter cartridges.

Application Fields

This high-precision titanium filter cartridge finds extensive application in the following sectors:

• Pharmaceutical Industry: Decarbonation and precision filtration in production processes for large-volume parenteral solutions, small-volume injections, oral liquids, etc.
• Food & Beverage: Clarification filtration for beverages, spirits, beer, vegetable oils, etc.
• Chemical Industry: Decarbonation and precision filtration for liquid products and pharmaceutical intermediates.
• Water Treatment Industry: Security filtration for ultrafiltration, RO, and EDI systems.
