Injection Moulding Machine for Floor Drains, Traps and Gratings
Floor drains, traps and gratings are formed on horizontal injection moulding machines from ABS, PP or PVC, the bodies with side cores and the gratings with many fine slots. Tonnage follows the projected area of the grating or body, the core pulls for outlet spigots and the depth of the trap. PVC needs a suited screw and short residence time.
For drains and traps, machine selection centres on core-pull circuits, a screw and barrel matched to the material and clean filling around grating slots. Pratishna Engineers supplies horizontal injection moulding machines for floor drain, trap and grating moulding and can recommend a configuration for your range.

Machine Requirements for Floor Drain, Trap and Grating Moulding
Drain bodies must seal and carry water away, while gratings sit at floor level where every mark shows. Points to check when choosing a machine:
- PVC-suited screw and barrel for UPVC drain bodies
- Core-pull circuits for outlet spigots and side inlets
- Even trap walls so the water seal holds
- Venting and gate layout that limit weld lines at slots
- Dry, clean plating-grade ABS for chrome-finish gratings
- Mould height for deep trap and bottle-trap bodies
Recommended Machine for Floor Drains, Traps and Gratings
Gratings, covers and small traps can run on the E Series (75-180 T). Larger drain bodies and multi-inlet traps with several core pulls need more mould space and shot capacity, so the C Series (140-320 T) is used, or the H Series (120-350 T) where the mould is taller or wider.

FAQs / Buyer Questions
Common questions from drain and trap makers.
Which Injection Moulding Machine Is Used to Make Floor Drains and Traps?
Small gratings and traps fit the E Series, and larger bodies with several side cores move up to the C or H Series. The choice rests on mould size, core-pull needs and the material being run.Can PVC Floor Traps Be Moulded on Any Machine?
PVC needs a screw and barrel built for it, with corrosion-resistant surfaces, controlled temperatures and no dead spots where melt can hold up and burn. Degrading PVC gives off acid that attacks steel and leaves dark streaks on parts.Does a Chrome-Look Grating Need Special ABS?
Yes. Gratings that are chrome plated after moulding use plating-grade ABS. The moulded surface must be free of flow lines, sink and moulded-in stress, or the plating shows the defect and may not bond. Steady filling and a warm mould help.
How Are Side Inlets on a Drain Body Moulded?
Side inlets and outlet spigots are formed by core pulls that move in before injection and out before ejection. The machine needs core-pull circuits with sequence control, and the mould needs room for the cylinders.Can Pratishna Recommend a Machine for My Floor Drain or Trap?
Yes. Share the drain, trap or grating drawing or sample, material, part weight, mould size, number of core pulls and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Plumbing Parts Too?
Yes. With the right screw and mould, similar machines can mould PVC and UPVC pipe fittings, bathroom fittings, flush tank parts and faucet aerators.
