Bronze powder sintered filter elements are created by sintering bronze alloy powder at high temperatures. They exhibit high filtration precision, good air permeability, high mechanical strength, and excellent suitability for high working temperatures and impact resistance. These elements find application in various fields, including pneumatic components, the chemical industry, and environmental protection.

TOPTITECH produces porous filter tubes that can be hollow or blind, with a minimum wall thickness of 1 mm. The tubes are made by isostatic compaction of powder in a flexible mold with the negative shape of the part, followed by sintering. The pore sizes can range from 0.2 to 100 microns. These filters find used as filter cartridges or aerators for high flow rates. They can be utilized as tubes straight away or with connectors of different geometry added at the ends.

Porous elements of various shapes, structures, different particle sizes, and porosity can be produced according to user requirements. Examples include covers, caps, sheets, tubes, and rod-shaped filter elements.

Products Processing

The production process starts with converting bronze into powdered form using various methods such as chemical decomposition, atomization, and grinding. The powder is then poured into a die and compacted under enough pressure to enhance adherence to contact points, all at room temperature. The resulting bronze part is then placed inside a furnace where extreme heat combines the molecules of the metal, creating a rigid, durable, and porous component. The manufacturing process can be tailored to specific shapes based on the client's requirements and specifications. In order to create bronze sieves, a mild molecule must be filled with a spherical pattern, and bronze must undergo sintering in order to maintain all of its visual properties. Sintering is the most preferred process for making filters with metallic materials, due to its ability to preserve the metal's integrity.

By sintering bronze alloy powder at high temperatures, which produces great mechanical strength, good air permeability, and precise filtering, bronze powder sintered filter components are created. TOPTITECH produces porous filter tubes and other shapes that can be customized according to user requirements. The production process involves converting bronze into powdered form, followed by compaction and sintering. Sintering is the optimal method for making filters with metallic materials, as it preserves the metal's characteristics.
