Line configuration & layout

An aluminium slug goes in one end; a printed, capped, leak-tested and sealed tube comes out the other. Follow the twelve steps below.

01 Slug feed & press Impact-extrude lubricated slugs into seamless blanks. 02 Trim & thread Roll thread, face head, trim tail, polish shoulder. 03 Anneal Relieve stress, restore ductility, clean lubricant off. 04 Buffer Cool and accumulate to sync line pace. 05 Internal coat Spray the inner protective film. 06 Cure Bake the internal coating to a stable film. 07 Base coat Even exterior base — the printing ground. 08 Print Up to 6-colour offset print + cure. 09 Leak test Continuous air-tightness inspection & sort. 10 Cap Torque-screw plastic caps automatically. 11 Tail latex Apply the tail sealant ring. 12 Pack Count, arrange and carton finished tubes.

Built on trusted components

SIEMENS control on every station.

Reliability starts with the parts inside. XUNTANG lines run SIEMENS PLC, servo drives and touch screens, with Schneider, Omron, SMC, FESTO and NSK/NTN components — so maintenance parts are available anywhere you operate.

Before you enquire

Common questions

What is a collapsible aluminium tube making line?

It is a fully automated line that turns aluminium slugs into finished, printed, capped and sealed collapsible tubes — the soft metal tubes used for cosmetics, ointments and pharmaceutical creams. XUNTANG builds the whole line as 16 integrated stations across 12 process steps, from impact extrusion to automatic cartoning.

What production speed can the line reach?

The line runs stably at 80–90 pcs/min, and the small-format line can reach up to 95 pcs/min. These figures are a reference for planning, not a contractual guarantee — actual throughput depends on tube size, artwork, coating and your factory conditions, which we confirm together before quotation.

Which machines are included in a complete line?

A standard line includes the extrusion press, trimming/threading machine, annealing oven, buffer accumulators, internal coating machine, curing oven, base coating machine, printing machine, leak detector, capping machine, latexing (tail sealing) machine and packing machine — plus the polymerization ovens and elevators shown in the 16-station layout.

What information should I provide before a quotation?

Tell us your tube diameter and length range, target output per minute, number of print colours, coating requirements, and the space available on your factory floor. With that we recommend the right line format (XT-S26 or XT-L26), configuration and layout.
