Tube seal testing, certification and validation
Find out why a seal fails, and stop it before it starts.
AnC is often called “the Dean of Tube Sealing” for its experience in tube filling and sealing. Our lab tests, certifies and validates tubes so you can find a production problem and fix it fast.
Is it the tube?
Is it the machine?
Is it the product?
Is it the setup?
Our lab answers all four.
Certification
Know your tubes before you run them
A certificate for one lot of tubes.
We test the lot with our patented process to confirm the tube can be sealed and find its burst limits in production. If a seal fails later, you have already ruled out the tube, so you can go straight to the machine or the process.
Data All the recorded data on the lot
Certificate Validation that the tube can handle your production specifications
Setup The recommended speed, heat and setup for your machine and that lot
How it works
Step 1 Call us before you send tubes, if you can
Step 2 Fill in the tube information form
Step 3 Send at least 100 tubes of one type, with the form and your machine’s brand and model
Step 4 Results take 3 to 5 days
For a standard tube we most likely have the right hot air nozzles. An unusual tube may need custom tooling, and we tell you first if that costs extra. Some customers book tests through the year on a yearly contract, at a reduced price.
Lab testing
In our lab, or yours
The limits of your tube, measured.
Using AnC instruments, we test a tube to its limits and find the settings that seal it best. That includes our own burst test analysis.
The PTS-100 runs our burst and pressure hold tests on your production floor.
What we find
Temperature The heat needed to seal
Speed The rate that performs best, in parts per minute
Pressure The pressure needed to seal
Date code Whether the date code stays legible
Settings The best sealing parameters for that tube
Incoming tubes Validation that a new delivery meets your standard
FingerPrint™
Optional seal monitoring for the TS-100 and other machines
Every seal leaves a trace.
A load cell between the sealing jaws and the carriage turns the jaw force into a signal, recorded over time. The trace shows the whole seal in detail.
Check Each seal is compared with a saved master. An alarm sounds when one drifts.
Coverage Every tube is checked, not a random sample by hand
Retrofit Can be added to many popular production machines
In the sample trace
Dwell 0.75 seconds with the jaws closed
Force 42 lb on the jaws
Melt 0.7 seconds, as the seal area melts and the force drops about 3.5 lb
The Art of
Tube Sealing
A hands on workshop
What makes a good seal, and how to test it.
A practical class on hot air tube sealing, general enough to cover the common machines, like Norden and IWK. Send some of your tubes ahead and, if we have the tooling, we can run them in class.
Where At your facility (1 day), or at our lab in Gardnerville, Nevada (2 days, up to 5 people)
Covers Sealing parameters, tube materials and tooling, machine setup, testing and QC
For Filling and tube teams, setup operators, QC and managers
Expert witness
Scientific data for disputes
When a seal fails, data settles it.
AnC provides expert witness services in disputes between tube manufacturers and processors. We can match a processor’s setup, burst test the lot and show what the tube can handle and why it failed.
Law firms: please contact us before you send any product.
“Thank you for all the information and education in the tube industry, you opened my eyes in this part of the cosmetic industry, I was very surprised about no standards in the manufacturing of the tubes!”
