Frequently Asked Questions About Reinforced Polypropylene Filter Plates
Q1: What does the glass-fibre reinforcement add?
It raises both the pressure and temperature ceiling: standard plates work to 16 bar and 80°C, high-pressure versions to 25 bar and up to 95°C. Reinforced feed eyes also resist distortion under pressure.
Q2: What sizes are available?
Plate sizes run from 250×250 mm to 2000×2000 mm, with thickness from 15 to 60 mm and chamber depth from 15 to 50 mm. Feed hole diameters range from 15 to 80 mm, and port layouts are customisable.
Q3: How are they manufactured?
By computer-controlled injection molding, followed by optimised cooling cycles that prevent internal stress. Each plate passes dimensional and structural inspection before surface finishing.
Q4: How do they compare with metal plates on maintenance?
Reinforced PP needs less maintenance than metal alternatives, does not corrode, and its smooth surface releases the cake cleanly, which shortens the cycle.
Q5: What is the expected service life?
3 to 5 years under normal operating conditions. Abrasive feed and sustained high-temperature duty shorten it, so plate condition should be reviewed at each cloth change.
