Injection Moulding Machine for Luer Lock Fittings
Luer lock and luer slip fittings and caps are made on horizontal injection moulding machines, usually in high-cavity hot runner moulds, from medical-grade PP, PC, ABS or COP. Cavity count and whether the thread needs an unscrewing core decide machine size and opening stroke. Flash-free tapers and threads matter most, because the connection is safety-critical.
Selection for luer parts focuses on repeatable filling across every cavity, a clamp that holds the parting line shut on fine threads and room for unscrewing drives. Pratishna Engineers supplies horizontal injection moulding machines for luer lock moulding and can recommend a configuration for your fitting and mould.

Machine Requirements for Luer Lock Moulding
Luer fittings are small but tightly toleranced, and the machine has to hold that tolerance in every cavity:
- Repeatable shot control for taper size in every cavity
- Clamp that keeps flash off tapers and thread crests
- Mould space and drives for unscrewing or rotating cores
- Hot runner tip control for balanced high-cavity filling
- Drying for PC and ABS before moulding
- Process records that support the customer validation file
Recommended Machine for Luer Lock Fittings
Luer fittings and caps are light, so cavitation rather than part size sets the clamp. Many luer tools fit the E Series (75-180 T) or a Hybrid PH Series (120-140 T) machine, whose electric injection gives repeatable shots. Very high-cavity or unscrewing moulds with large hot runner plates may need the H Series (120-350 T), or the C Series for wider moulds.

FAQs / Buyer Questions
Questions luer fitting makers raise when planning a new tool.
Which Injection Moulding Machine Is Used to Make Luer Lock Fittings?
A horizontal machine sized by the cavity layout. E Series and Hybrid PH machines cover many luer tools, and very high-cavity moulds with unscrewing drives can move up to the H or C Series.How Are Luer Lock Threads Released From the Mould?
Internal threads usually need unscrewing or rotating cores, while some external threads can strip off or use split slides. The release method changes mould height, opening stroke and cycle, so it is settled before the machine is chosen.Why Is Flash on a Luer Taper a Reject?
The taper seals by fit alone, so a thin flash line can cause a leak or a loose connection. Worn parting lines, low clamp or excess injection pressure are the usual causes, and the part is rejected rather than trimmed.
What Do Customers Check Across Luer Cavities?
Buyers usually audit capability cavity by cavity rather than average size. That needs balanced hot runner filling, steady mould temperature and process validation records, since inspection alone cannot confirm every taper fit.Can Pratishna Recommend a Machine for My Luer Lock?
Yes. Share the fitting drawing, resin grade, cavity count, thread release method, hot runner details and mould dimensions, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Small-Bore Medical Parts Too?
Yes, subject to the mould. The same machines often run medical fluid connectors, needle hubs, pharma vial closures and IV set components, with the tonnage set by each cavity layout.
