The Crimper Control is used to control the height obtained following crimping. Our range covers all standard Øs: 13-15-17-18 & 20.

Determining the value “H” to be checked on the neck can be performed in two separate ways:
- The theoretical way requires the time needed to collect information from your suppliers
- The other, practical way has the advantage of enabling you to start using the “Crimper Control” straight away.
H = value to be checked
Th = the thickness of the metal on the dish
J = the thickness of the compressed joint
V = the height of the neck, excluding the vee-ring
P = the thickness of the platform (only available for certain types)
Equation for the value to be checked
H = 2 Th + J + V + (P)
Min. value = H
Max. value = H + 0.3
Adjust crimping by following the guidelines ordinarily used for this type of operation.
Once crimping has been obtained, check its outward appearance and airtightness using the means at your disposal. In our opinion, using a decompression chamber is the most effective way of highlighting any issues with airtightness.
Once a crimped vial has successfully passed these tests, it can then be used as a control sample. The reference value “H” will be the one taken from this crimp using the “Crimper Control”.
The following checking data will be taken from this sample:
Min. value = H - 0.1
Max. value = H + 0.1
