Injection Moulding Machine for Baby Bath Tubs
Baby bath tubs are moulded on large horizontal injection moulding machines, often two-platen types, in PP or HDPE. Tub length, side wall depth and the resulting projected area push clamping force high, and mould height and opening stroke must clear a deep shell. Fill and cooling balance matter most, since long flow paths cause warpage along the rim.
For bath tubs, selection depends on tub size, mould dimensions and wall thickness, so each project needs a review of the part. Pratishna Engineers can study the tub and mould and advise whether its two-platen, horizontal or special purpose injection moulding machines fit the project.
Moulding Baby Bath Tubs?
Share your tub drawing, size and material, and Pratishna Engineers will review the part and mould.
Machine Requirements for Baby Bath Tub Moulding
Bath tubs are among the largest baby care mouldings, so mould size and flow length drive every machine choice. Consider:
- High clamping force for a large tub projected area
- Platen size and tie-bar spacing for wide tub moulds
- Opening stroke to eject a deep tub shell
- Multi-point hot runner gating for long flow paths
- Balanced cooling to keep the long rim flat
- Non-slip texture on the tub floor and smooth rim
Recommended Machine for Baby Bath Tubs
Bath tub moulds need high clamping force, often beyond the series listed here. Share the tub size, weight and mould so Pratishna Engineers can advise. PHM (160-350 T) and H Series (120-350 T) machines may suit smaller bath accessories after review, and special purpose machines built to application can be discussed for the tub itself.

FAQs / Buyer Questions
What buyers ask before starting a baby bath tub project.
Which Injection Moulding Machine Is Used to Make Baby Bath Tubs?
Bath tubs are large shells that call for high-tonnage machines, often of the two-platen type, sized to the tub. Pratishna Engineers reviews each tub and mould before advising on a machine.Why Are Two-Platen Machines Used for Large Tub Moulds?
Tub moulds are wide, tall and heavy. A two-platen design gives a large platen and long opening stroke in a shorter machine length, which helps when the mould is big and the part deep.How Is Warpage Controlled on a Long Tub Rim?
Sequential or multi-point gating shortens flow length, even wall thickness limits uneven shrinkage and balanced cooling keeps the rim in plane. Thick walls may also need a longer cooling time.
Is PP or HDPE Better for a Baby Bath Tub?
PP gives a stiffer tub with better gloss and heat resistance for warm water. HDPE is tougher and more flexible but shrinks more, which makes flatness on a large rim harder to hold.Can Pratishna Recommend a Machine for My Baby Bath Tub?
Yes. Share the tub drawing or sample, outer dimensions, part weight, material, mould dimensions and planned output, and Pratishna Engineers will review the project and advise.Does the Machine Suit Other Large Baby Products Too?
Depending on size, these machines can mould baby potties, baby chair parts, stroller parts and milk powder containers. Each mould is checked against the machine first.
