How Do We Control Your Sintered Plastic Filter?
Raw Material
BLUE always insist on choosing a uniform powder of raw material to produce each of your porous PTFE filters with great pore size, high tensile strength, and temperature stability.
Powder Filling
Our ultra-efficient industrial tools closely monitor the powder filling process to convert sintered raw materials into the porous PTFE filter at very affordable rates.
Vacuum Sintering
BLUE strictly controls the parameters of the high sintering process of sintered filters to give them good mechanical properties by applying heat and pressure.
CNC Machining
We use a high-precision machining process for manufacturing sintered filter by using innovative techniques to meet precision filtration characteristics.
Size Inspecting
BLUE inspects all the sizes of the sintered filter by applying a pressure gauge and high-efficiency size monitoring pieces of equipment.
Porosity Testing
We perform a filtration test to check the sintered filter’s strength, shape, porosity, distribution rate, permeability, flow control, and filtration rate.
Part Assembling
We only assemble sintered filter parts after passing through extensive quality assurance procedures to ensure the satisfaction of our clients.
Filter Packaging
BLUE pack all sintered filter products and accessories following international standard safety procedures to meet the criteria.
FAQ
First, we select PTFE powder with carefully controlled particle sizes to achieve the desired pore structure in the filter.
Next, the PTFE powder is compacted into the die cavity by the press under a pressure of 20-235 MPa.
Finally, the pressed PTFE filter is sintered in a furnace at 370℃-380℃ to form the finished product.
