The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.
The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel Sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

Industrial fine filters are widely used in industries such as pharmaceutical, chemical, ink and paint, food and beverage, automobile manufacturing, cement industry, petroleum, oil refineries, petrochemical, etc. It is important to clean these filter cartridges to ensure that they filter consistently over a long period of time.
Industrial filter cores provided by Song Phung have high dirt holding capacity, are easy to install, clean and maintain. The fine filter element is sturdy, has a solid quality core and has well-formed layers, so cleaning and installing them is very easy.
Some filtration systems allow backwashing and have a CIP system design. But most have to be taken out of their shells, sterilized and washed. When not in use, these cleaned filter cartridges are dried and sealed or vacuumed to prevent contamination or wear.
The main materials are stainless steel wire mesh (for smooth pores, high temperature resistance, and easy cleaning) and stainless steel sintered fiber (for high porosity, superior dirt holding capacity, and strong regeneration ability).
Our polymer candle filter elements support a filtration rating range from 1 to 200 microns, withstanding operating temperatures up to ≤350°C and a maximum allowable pressure differential of 10 bar / 14 psi.
We supply standard connector types including 222, 226, 215, M36, M28, M24, M22, and M20 to suit specific polymer melt filtration application requirements.
They are extensively applied in petrochemical refining, metallurgy hydraulic systems, textile polyester melt drawing, electronics, pharmaceuticals, thermal power plants, and nuclear power operations.
Some systems support online backwashing or clean-in-place (CIP) designs. Alternatively, cartridges can be removed, sterilized, washed, and then dried and sealed or vacuumed for safe storage.
