Bowl Moulds

PCL manufactures a full range of three, four and five-part open and stuck on rim bowls. These are used in conjunction with our PCB5/70 and RotoBowl range of casting machines. We can manufacture bowls from plaster moulds, models, free issue block or case moulds and 3D product scans.

Each mould is manufactured in an integral reusable frame. This unique frame was designed and developed by PCL and encapsulates the upper and lower parts of the bowl mould.

This simplifies the process of applying verticle load to the bowl mould allowing 8 moulds to be cast on the same machine at the same time.

Our bowl mould design is compatible with all our bowl casting systems and the same mould can be cast on both our modular and beam casting system. When used in conjunction with our Slide mould system our RotoBowl cell can cast a full range of stuck on rim bowls.

Typical WC Bowl Production Outputs

WC bowls are manufactured on high pressure
casting systems including:

  • Machine PCB5/70; RotoBowl

Close to close cycle times (including casting and demoulding).
These may vary subject to slip properties.


The outputs are based on the following assumptions:

  • Days operated per year = 350
  • Hours operated per day = 24
  • Machine utilisation = 95%
Machine Type / Demould Cycle Times (Min) No. of Moulds Cavities Per Mould Casts Per Year
Open rim PCB5/70 24 8 1 159,600
Open rim RotoBowl 16.5 2 1 58,036
Stuck on box rim RotoBowl 18 2 1 53,200

Our range of two-part moulds are also manufactured in steel frames for the same reasons as above, these include tanks, covers, basins, pedestals, pans, urinals and shower trays and are cast on our PC5/70, PC120, RMS and Slide casting systems. We manufacture our moulds from free issue blocks, cases, plaster moulds and models. For each new mould design we carry out a full review and development program including piece approval, and all our moulds are test cast prior to shipment.

In general our moulds are made from fine pore material, unless otherwise requested. This tightly controlled pore structure gives the following benefits; greatly improves product surface quality, reduces susceptibility to mould blinding and avoids the need for water flushing between casts.
