Can I replace only the extruder screw?

Yes, if the barrel bore is still round, within the agreed condition limits and compatible with the new screw, while the interfaces and alignment are sound. The decision should be based on a measured screw-to-barrel condition, not on the screw appearance alone.

What happens if a new screw is installed in a worn barrel?

Excessive or uneven clearance can allow more leakage across the flight, reduce effective pumping and leave the new screw unable to correct output, pressure or melt-consistency problems caused by the barrel. Local barrel wear can also create uneven loading on the new screw.

How should barrel wear be measured before replacement?

Measure the bore at several axial stations and in more than one angular direction. Record the measuring method, instrument and temperature, then compare the resulting diameter and out-of-round pattern with the approved drawing or an agreed replacement basis.

Does a worn screw always require a new barrel?

No. A worn screw does not automatically condemn the barrel. If inspection shows that the bore, roundness, surface and interfaces remain suitable, replacing or rebuilding the screw alone may be the more sensible choice.

Should every replacement use a bimetallic screw and barrel?

No. The surface system should match the resin, fillers, corrosive ingredients, temperature and expected run time. Standard nitrided components can be appropriate for less abrasive duty, while harder alloy systems may be justified for glass-filled, mineral-filled, recycled or corrosive materials.

What should I send Nanhaiya for a replacement recommendation?

Send the machine make and model, polymer and formulation, product, normal speed and output, operating symptoms, screw drawing or measured dimensions, barrel-bore measurements, photos of worn surfaces, interface dimensions and any planned change in material or production duty.
