Injection Moulding Machine for Oxygen Mask Components
Oxygen mask components such as elbows, tubing connectors and valve bodies are made on horizontal injection moulding machines from PP, PC or TPE, with two-shot machines for rigid-plus-soft parts. Cavity count and side actions for curved bores set mould size more than clamp force does. The soft mask shell itself is often flexible PVC or thermoformed sheet.
Machine choice depends first on whether the design bonds rigid and soft material in one part. Pratishna Engineers builds special purpose machines to application for two-shot versions and supplies standard horizontal injection moulding machines for single-material elbows, connectors and valve bodies.
Moulding Oxygen Mask Components?
Share the part drawings, materials and whether a soft second shot is needed, and Pratishna Engineers will advise on the machine.
Machine Requirements for Oxygen Mask Component Moulding
Mask components are small airway parts that join tubing, swivel and seal. Selection usually covers:
- Curved elbow bores formed with core pulls or slides
- Connector tapers free of flash for a firm tubing fit
- Thin valve flaps filled fully with good venting
- PVC-suited screw and barrel for soft PVC parts
- Dried PC for clear elbows and swivels
- Second shot station for soft seals on rigid bodies
Recommended Machine for Oxygen Mask Components
Two-shot elbows or valves with a bonded soft seal need a special purpose machine built to application, which Pratishna Engineers supplies. Single-material elbows, connectors and valve bodies are small parts that usually run on the E Series (75-180 T). Family moulds carrying many slides move to the H Series (120-350 T) or the C Series (140-320 T).

FAQs / Buyer Questions
Questions respiratory product makers ask about moulding mask parts.
Which Injection Moulding Machine Is Used to Make Oxygen Mask Components?
For single-material elbows, connectors and valve bodies, a horizontal E Series machine in most cases, or the C or H Series for larger family tools. Rigid parts with a bonded soft seal need a special purpose two-shot machine.Is the Soft Mask Shell Injection Moulded?
Often not. Many shells are flexible PVC or thermoformed sheet made on other equipment. This page covers the rigid and semi-rigid parts that are reliably injection moulded, such as elbows, connectors, nose clips and valves.Can Soft PVC Be Moulded on the Same Machine as PP and PC?
It can, but PVC needs a screw and barrel suited to it and careful temperature control to avoid degradation. Switching between PVC and other resins calls for a full purge, so many moulders keep one machine for PVC work.
What Does a Two-shot Rigid and Soft Design Change?
It bonds a TPE seal or cushion onto a PP or PC body in one machine cycle, removing a manual assembly step. The material pair must bond, and the machine is built to the application, so it is quoted from the part and mould.Can Pratishna Recommend a Machine for My Oxygen Mask Component?
Yes. Share drawings or samples of each part, materials, part weights, mould dimensions, cavities, any second shot, any clean moulding area plan and yearly quantity, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Respiratory and Fluid Parts Too?
Yes. Similar machines can mould inhaler actuators and spacer parts, medical fluid connectors, luer lock fittings and IV set components, depending on the mould and material.
