Injection Moulding Machine for Electrical Conduit Fittings
Electrical conduit fittings such as bends, couplers and round boxes are made on horizontal injection moulding machines with PVC-suited screws, mainly from rigid UPVC and PVC, with PP for some ranges. Machine size depends on conduit diameter, cavities per mould and box depth. Controlled melt temperature matters most, because overheated PVC degrades and burns.
For a conduit fitting range, machine selection looks at the largest box mould, the spread of conduit sizes and how often moulds are changed. Pratishna Engineers supplies horizontal injection moulding machines for conduit fittings and can recommend a configuration for your range.

Machine Requirements for Conduit Fitting Moulding
A conduit fitting has to grip the conduit firmly, survive site handling and pass the conduit standard its market requires. Points to check before choosing a machine:
- PVC-suited screw, barrel and nozzle with corrosion protection
- Close melt temperature control to avoid burn marks
- Socket bores held to the conduit outer diameter
- Core pulls or slides for bend and box entries
- Opening stroke for deep round and looping boxes
- Quick mould change across many conduit sizes
Recommended Machine for Electrical Conduit Fittings
Couplers and small bends for light conduit are a good match for E Series machines (75-180 T) with multi-cavity moulds. Larger conduit sizes, deep boxes with several entries and moulds carrying side cores need more clamp and platen room, which points to a C Series machine, or the H Series (120-350 T) where mould height is the limit.

FAQs / Buyer Questions
Questions conduit fitting makers ask before buying a machine.
Which Injection Moulding Machine Is Used to Make Electrical Conduit Fittings?
A horizontal machine with a PVC screw and barrel. Small couplers sit comfortably in the E Series, while larger bends and deep junction boxes with side entries often move up to the C or H Series.Why Does PVC Need a Special Screw and Barrel?
PVC releases corrosive gases if it overheats or stays too long in the barrel. A PVC-suited screw with low shear, a corrosion-protected barrel and short residence time limit degradation, black specks and burn marks.How Are Bends and Box Entries Moulded?
Curved bends and side entries on boxes are formed by core pulls or slides that move out before ejection. The number of side actions affects mould size and the platen area the machine needs.
Can One Machine Run Several Conduit Sizes?
Yes, if the largest mould fits the platen, tie-bar spacing and opening stroke. Plan the machine around the biggest box or bend, and keep shot size suitable for the smallest coupler so the screw does not hold PVC too long.Can Pratishna Recommend a Machine for My Conduit Fittings?
Yes. Share drawings or samples, conduit sizes, material grade, part weights, mould dimensions, cavity plans and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Electrical Building Products Too?
Often, yes. The same class of machine can mould junction boxes, PVC trunking accessories, cable clips and saddles, and wall plugs, subject to the mould and material.
