Core process
Tube material layers, diameter, length, tail shape, and cap type jointly change clamping, sealing, trimming, and special cap tooling.
When starting from empty tubes, tube positioning, ointment filling, and tail sealing are included in the same main machine scope, evaluated with actual tubes and materials.
When tubes are already filled, downstream equipment handles tail sealing, corresponding characters, and trimming; do not duplicate front-end filling configuration.
Flip caps, nozzle caps, pumps, or other special structures use complete tube-cap assembly to verify orientation, fixtures, and closure action.
Arrange conveying after tube orientation and spacing are stable; additional date batch number is test-printed by collaborative equipment on available surface outside tail.
Coding consumables are test-printed on real tubes; liquid contact seals and cleaning consumables follow actual filling parts; changeover parts are established by main diameters.
Sample details
Tube incoming state determines filling and sealing or tail post-processing; tube material and tail shape determine molds and fixtures.
Please provide empty tubes, filled sample tubes, caps, material layers, diameter, length, tail shape, and qualified finished product photos.Actual material state affects filling components, finishing, and pre-sealing cleanliness; cannot be judged by empty operation only.
Please provide representative materials, describing flow, particles, stringing, temperature, target fill volume, and tail residue after filling.Sealing, characters, and trimming share tail space; layout should be coordinated before mold making.
Please provide tail pattern, character content, character position, trimming contour, and mutually approved finished sample tubes.Collaborative coding requires stable tube orientation; automatic conveying also needs to check direction, spacing, and abnormal tube removal.
Please mark the printable area on the tube body, batch number content, reading direction, upstream/downstream stations, and on-site conveying layout.Complete trial for main specifications first, then expand food-grade sealing, cleaning consumables, and changeover parts list.
Please provide production schedule for each tube, changeover frequency, liquid contact cleaning method, seals, and planned spare molds and fixtures.Common selection mistakes
First clarify whether it is empty tube filling and sealing or post-processing of filled semi-finished tubes, then discuss coding, trimming, and conveying.
Different tube materials cannot use untested molds and processes; recheck tail seal pattern after material change.
Official character content should be submitted together with the tail finished style; additional tube body batch numbers are handled by a collaborative coding device.
For special cap tube sealing solutions, fixtures and actions are determined based on actual samples, not by appearance photos.
During actual material trial, record cleanliness after filling, tail seal pattern, characters, and trimming, not just adjust the sealing station.
View detailed technical notes
First distinguish between empty tubes and pre-filled tubes
The condition of the tube when it enters the equipment determines whether ointment filling is included. Empty tubes use the filling and tail sealing main machine; pre-filled tubes only go through tail post-processing.
Tube material, tail shape and ointment condition together determine the tooling
Plastic tubes and aluminum-plastic composite tubes also need a closer look at layers, tube diameter and tail shape. The flow, particles and residue of the ointment affect filling and tail cleanliness.
Empty tubes use the fully automatic filling and tail sealing main machine
The fully automatic tube filling and tail sealing machine is configured around empty tube positioning, ointment filling and tail sealing. First confirm the tube material, diameter, tail shape, fill volume and ointment condition, then use formal sample tubes with actual material to check positioning, filling finish, tail cleanliness, seal pattern and trim samples. Available modules and operating ranges are confirmed per project.
Pre-filled tubes use the tail sealing and coding equipment
The tube tail sealing and coding machine receives tubes that have already been filled, and handles matching tail sealing, characters and trimming. The front section must also control tail residue. After entering the equipment, use sample tubes from the same batch to observe positioning, seal pattern, character position and trim outline. If continuous production from empty tubes is required, switch to a main machine that includes filling.
Special caps require separate verification of fixtures and closing action
Flip caps, pointed spout caps, pump heads or structures with inner plugs enter the special cap tube sealing solution. The tube head and cap must be provided as a set. During trial runs, observe orientation sorting, clamping stability, screwing or pressing action, and the appearance after closing. If standard threaded caps need no special handling, return to the matching standard cap branch.
The same batch of sample tubes runs through tail sealing, coding and trimming
Tube material, diameter, tail shape, characters and trimming are checked against finished sample tubes from the same batch, to avoid different appearance standards at different stations.
Additional batch numbers are trial-printed along a stable tube orientation
When date or batch numbers are needed in addition to tail characters, the automatic feeding, conveying and sealing line first maintains the tube orientation, then a collaborative date/batch inkjet coder trial-prints in the available area.
Coding and maintenance consumables are matched to the actual section
Labels, inkjet ink and thermal transfer ribbon are verified on the tube surface. Food-grade sealing rings, cleaning consumables and change parts follow the filling section and cleaning conditions.
Rebuild finished samples when changing tube diameter
The main tube diameter and tail shape complete the mold and fixture trial production first. New specifications then verify clamping, sealing, characters and trimming; do not just replace a single part.
Common questions
Should empty tubes and already-filled tubes use the same equipment?
No. Empty tubes require a filling and tail sealing main machine; already-filled tubes only need post-processing for tail sealing and coding. The incoming state must be stated first.
What operations does a fully automatic tube filling and sealing machine include?
Project configuration is based on empty tube positioning, ointment filling, and tail sealing. Available modules and trimming range are evaluated with actual tubes and materials.
Can we communicate if we don't have tube samples yet?
You can first provide tube material, diameter, length, tail shape, cap type, and finished product photos to determine the direction. Molds, fixtures, and sealing conditions still need to be finalized with actual samples.
How are tail characters and tube body coding arranged?
Tail characters and sealing pattern are verified together. Additional variable information on the tube body is test-printed by a collaborative coding device under stable orientation.
Can plastic tubes and aluminum-plastic composite tubes share molds?
It is necessary to compare tube material layers, diameter, tail shape, and sealed samples. Similar dimensions do not eliminate the need for material and finished product testing.
How to determine automation actions for special caps?
Use the complete tube-cap assembly to observe orientation, clamping, and actual closure, then decide on screw capping, press capping, or other tooling. Do not rely solely on cap type names.
