1. How does the device test different sized closures?
The device uses interchangeable chucks, each of which is custom designed by PTI (if the design does not already exist). PTI has a chuck library of several "standard" designs. The device comes with a chuck.
2. How does the device grip the closure?
The chucks are designed to be an exact mate to the closure; the "reverse" version of the shell design. These interchangeable chucks will always grip to the closure in the same fashion, thus reducing the gripping variances that may exist from user to user. In most cases the chuck simply grips to the ribs of the cap rather than squeezing or compressing it.
3. What size closures is the TorqTraQ® Device used on?
- Standard chucks (Type I) can be used on closures between 15-43mm.
- Customized chucks (Type II) can be designed for push-pull, sport cap, flip top, and other unique closures.
- Capper setup chucks (Type III) allow measurement of static torque on capping heads. These are discussed in greater detail in another document.
4. How is the device calibrated, and how often?
PTI completes all the TorqTraQ® device calibrations in-house with a recommended calibration cycle of one year. The unit is calibrated using the ASTM D3474-90 standard, and a calibration certificate is provided.
5. What kind of training can PTI provide?
While the device is fairly simple and the documentation very good, it is recommended that when a device is introduced into an organization to schedule training, implementation and a verification session. PTI personnel will conduct the training, ensure that all operators understand the use of the unit, provide a customized SOP and run gauge verification while on-site. Please contact PTI for timing and costs of this on-site training.
6. For chuck design, what file-types do you accept?
If we currently do not have a chuck designed for your closure, we will design one for you. We accept many 3D CAD file formats such as (.x_t, .igs, .stp, .prt). The files can be emailed to torqtraq@plastictechnologies.com, or can be uploaded via our secure FTP server (for larger files). Please email us for FTP instructions.
7. Is my closure information secure and confidential?
Confidentiality is the #1 priority at PTI. Your information and files are of high confidentiality and safe with us. Nondisclosure agreements are available if required.
8. How long does the chuck design process take?
Chuck design could take 1-2 weeks based on requirements by the customer and PTI’s schedule. A firm delivery date will be provided upon receipt of order and our review of the 3D file.
9. Does PTI confirm chuck fitment?
Yes. PTI recommends that TorqTraQ® device customers provide a few closure samples along with a 3D file. This helps the design process, and allows PTI to test chuck fitment when they are complete.
