Ultra Mould engineers precision PET jar moulds from 1L to 20L in Ahmedabad — mirror-finish cavities for jars that sell on the shelf and run without downtime.
Jar moulds are not scaled-up bottle moulds. Bigger cavities, heavier steel, and wide-mouth necks demand different engineering.
15L and 20L jars need deep cavity blocks machined on 5-axis VMC with uniform cooling channels — or the jar walls blow uneven and the base sags.
Jar caps seal on the neck finish. We hold neck concentricity to micron tolerance so your caps never leak — the #1 complaint with low-grade jar moulds.
A 20L water jar is a glass-clear product. Ra 0.2 mirror polish across the full cavity keeps every jar crystal clear, batch after batch.
One mould base, interchangeable inserts for multiple jar sizes — the economical route for brands running 1L, 2L, and 5L jars on one machine.
From 5L water jars to 20L dispensing jars and wide-mouth confectionery jars — jar moulds are our strongest PET category. Heavier steel blocks, deeper cavities, and perfect neck-finish concentricity demand a serious tool room. Need a jar mould for production? WhatsApp our engineering team your jar sample or drawing — we reply with cavities, lead time, and pricing within 12 working hours.
