Injection Moulding Machine for Sliver Can Components
Sliver can components such as bases, castor wheels, top rings and spring plate parts are moulded on horizontal injection moulding machines in PP copolymer, HDPE or glass-filled PA6. Ring and base diameter set mould size and tie-bar spacing, while cavities set tonnage. Castor wheels need a concentric bearing seat and void-free hubs to last.
Machine selection for these parts weighs platen space for wide ring and base moulds, holding pressure for thick wheel sections and wear protection for glass-filled forks. Pratishna Engineers supplies horizontal injection moulding machines for sliver can part production and can recommend a configuration.
Moulding Sliver Can Parts?
Share the can size, the parts you want to mould and the materials, and Pratishna Engineers will suggest machines.
Machine Requirements for Sliver Can Component Moulding
Sliver cans roll and load all day on mill floors, so the moulded parts call for:
- Platen and tie-bar space for wide ring moulds
- Round top rings that do not go oval
- Void-free castor hubs with a concentric bearing seat
- Spring plate parts that survive constant cycling
- Dried glass-filled PA6 for castor forks
- Impact-modified copolymer for bases and rings
Recommended Machine for Sliver Can Components
Castor wheels, forks and small spring plate parts fit the E Series (75-180 T) in multi-cavity tools. Bases and top rings are larger and wide, so tie-bar spacing and clamping force put them on the C Series (140-320 T) or, for the widest cans, the H Series (120-350 T). Check ring diameter against the mould space first.
Not Sure Which Machine You Need?
Send can diameter and part samples for a machine size that fits the moulds.

FAQs / Buyer Questions
What sliver can makers and spinning mill spares buyers ask first.
Which Injection Moulding Machine Is Used to Make Sliver Can Parts?
It depends on the part. Castors and small spring plate parts fit the E Series, while wide bases and top rings need the mould space and clamping force of the C or H Series.Which Sliver Can Parts Are Injection Moulded?
The base, castor wheels and forks, top ring and spring plate components. The can body is usually fabricated or rotomoulded and is not made on an injection moulding machine.Why Do Castor Wheels Fail Early on Mill Floors?
Voids in a thick hub or an off-centre bearing seat make the wheel run rough and crack. Gating into the thick section, enough holding pressure and cored-out hubs reduce voids, and the bearing is pressed in after moulding.
How Are Large Top Rings Kept Round?
Rings go oval when cooling is uneven or several gates leave weak weld lines. Balanced gating, even cooling around the circumference and cooling the ring on a fixture after ejection keep it round.Can Pratishna Recommend a Machine for My Sliver Can Parts?
Yes. Share the can diameter, part drawings or samples, materials, part weights, number of cavities, mould dimensions and monthly quantity, and Pratishna Engineers will suggest suitable machines.Does the Machine Suit Other Spinning Mill Parts Too?
Yes. The same machines can mould textile trolley trays, creel pegs, cone holders and warp beam flanges, subject to the mould.
