Filter plate for the extrusion or injection machines.
Measures 30mm diameter by approx 4mm thick. As per the Precious Plastic specifications except that it is recommended to have "at least 16 holes of 1.5mm diameter", this has 25 holes 1.5mm dia. equally spaced to give an even flow.
This plate not only prevents foreign objects from reaching the nozzle (eg, bits of paper labels or aluminium foil) but it also traps any unmelted chips of plastic and holds them against the plate until they melt and can pass through the holes, ensuring that only molten clean plastic reaches the nozzle.
NB. as this is a small and cheap item international shipping will be standard, not tracked. Tracking would not be worth the extra cost.
