Important points before you shortlist a machine
02
Cap and neck finish
The neck finish and thread consistency affect cap start and torque. Samples should represent real production components rather than prototype-only packs.
03
Scaling the capping process
A small plastic bottle line may start with semi automatic capping, then move to inline or spindle capping when output grows.
Send your bottle, cap and output details to Lancing UK.
Include cap diameter, closure type, bottle size, target output, available space and whether the capper needs to connect to filling or labelling equipment.
