Injection Moulding Machine for Faucet Aerators and Nozzles
Faucet aerators and nozzles are small parts moulded on horizontal injection moulding machines, with POM for internal flow inserts and threaded parts, and ABS or PP for outer shells and caps. Cavity count, shot weight against barrel size and unscrewing cores for threads set the machine. Fine flow holes need good venting and flash-free shut-offs.
Aerator moulding puts the weight of machine selection on small-shot accuracy, a barrel sized so POM does not sit too long, and unscrewing support for threaded parts. Pratishna Engineers supplies horizontal injection moulding machines for aerator and nozzle moulding and can recommend a configuration.

Machine Requirements for Faucet Aerator and Nozzle Moulding
An aerator stack has several small parts that must thread, seal and pass water evenly. Points to check when selecting a machine:
- Barrel sized to the shot so POM is not degraded
- Unscrewing or collapsible cores for internal and external threads
- Clean shut-offs so fine flow holes stay open
- Venting at the hole field to stop burn marks
- Steady mould temperature to hold POM shrinkage on threads
- Balanced filling of small parts in multi-cavity moulds
Recommended Machine for Faucet Aerators and Nozzles
Aerator parts are light, so the E Series (75-180 T) covers many single and multi-cavity aerator and nozzle moulds. Unscrewing moulds with many cavities, or several parts run in one tool, may need the larger mould space of the H Series (120-350 T). A smaller screw diameter keeps POM residence time short.

FAQs / Buyer Questions
Questions aerator and nozzle makers ask before a machine trial.
Which Injection Moulding Machine Is Used to Make Faucet Aerators?
An E Series horizontal machine handles many aerator and nozzle moulds, since the parts are light. Larger multi-cavity or unscrewing moulds move to the H Series for platen space and stroke.Why Is POM Used for Aerator Inserts and Threads?
POM is stiff, low-friction and stable in water, so threads engage cleanly and fine holes hold their size. It needs controlled melt temperature and venting, because overheated POM gives off formaldehyde and leaves burn marks.How Are Threads on Aerator Parts Moulded?
Fine internal threads are often released by an unscrewing core driven by a motor or rack, or by a collapsible core. External threads can sometimes be split across the parting line. The machine needs matching core-drive outputs.
What Causes Blocked Holes in Moulded Aerator Discs?
Flash at worn pin shut-offs, trapped air and short shots in thin webs between holes can block flow holes. Sharp shut-offs, venting near the last-filled area and steady injection speed keep holes open across all cavities.Can Pratishna Recommend a Machine for My Aerator or Nozzle?
Yes. Share the part drawings or samples, material, part weights, thread type, mould size, number of cavities and monthly quantity, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Tap and Fitting Parts Too?
Yes. Similar machines can mould bathroom fitting parts, wall plugs, tile spacers and soap dishes, depending on the mould and material.
