Injection Moulding Machine for Non-return, Check and Foot Valve Components
Non-return, check and foot valve components, such as bodies, seats, poppets and strainer covers, are moulded on horizontal injection moulding machines in PP, POM or glass-filled PA66. Body size and cavities per tool decide the machine. A seat that stays flat matters most, because cracking pressure and reseal depend on it.
Selection centres on steady packing and cooling so seats come out flat and poppets or flaps keep the same stiffness shot after shot. Pratishna Engineers supplies horizontal injection moulding machines for check and foot valve parts and can recommend one for your valve sizes.

Machine Requirements for Check and Foot Valve Component Moulding
Check valves open and close on a pressure difference, so small moulding variation changes how they behave. Machine selection should allow for:
- Flat, flash-free seats for consistent cracking pressure
- Repeatable shot weight so poppet and flap stiffness stays even
- Material grade checked against the media at working temperature
- Fine strainer slots in foot valves without short shots
- Drying for glass-filled PA66 bodies and poppets
- Mould space for foot valve bodies with integral strainers
Recommended Machine for Check and Foot Valve Components
Poppets, seats, flaps and small check valve bodies run on the E Series (75-180 T) in multi-cavity tools. Foot valve bodies with strainer cages and larger in-line check valves suit the C Series (140-320 T), with the H Series (120-350 T) kept for the biggest foot valves or family tools.

FAQs / Buyer Questions
Questions pump and valve makers ask about moulding check and foot valve parts.
Which Injection Moulding Machine Is Used to Make Check and Foot Valve Components?
Lower tonnage horizontal machines handle poppets, seats and small bodies, often in multi-cavity tools. Foot valves with integral strainers and larger check valve bodies need a middle tonnage machine with more platen area.What Decides the Cracking Pressure of a Moulded Check Valve?
Seat flatness, poppet or flap stiffness and the spring. Warp on the seat, flash at the parting line or wall variation in the flap shifts the opening point, so packing, cooling and parting line condition need close control.Can the TPE Flap Be Moulded Onto the Valve Part?
The flap can be moulded separately and assembled, using a standard machine. Overmoulding TPE onto the rigid part needs a two-material process, which Pratishna Engineers can discuss as an enquiry with your part details.
How Is the Material Chosen for Chemical Duty?
Compatibility with the pumped media has to be confirmed at operating temperature, not at room temperature. PP covers many water and mild chemical duties, while PVDF takes aggressive chemicals and higher temperatures.Can Pratishna Recommend a Machine for My Check or Foot Valve?
Yes. Share drawings or samples of the parts, materials, part weights, mould sizes, cavities per tool and annual quantity, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Fluid Handling Parts Too?
Yes. Comparable machines mould strainer baskets, ball valve balls and stems, diaphragm pump valve plates and pump connectors, subject to tool size.
