Manual and Automatic Cap Closure Test Stands

Our systems ensure that the torque or load values measured are not influenced by an operator, side load, undue compressive load, or any other induced error. Such influences are removed by incorporating a bidirectional variable speed motor, cap and bottle adapters machined or molded to match the test article, automated axial alignment, accurate transducers, and minimal bottle deformation.

Features
  1. Unique design of fixtures and automatic controls allows the motor and transducer to do all the work, eliminating operator variability.
  2. Robust for production line testing, accurate enough for quality control in lab testing situations.
  3. Efficient, one button Auto-Test mode enables the operator to test more bottles in less time. Cycle times of under 10 seconds are possible on automated systems.
  4. Measures and verifies cap "on" torque and cap "off" torque (with on-torque option.)
  5. Individualized and accurate design of components accommodates most bottle sizes and thread configurations.
  6. Integrated bottle height sensor eliminates manual limit adjustments ensuring fast setup times.
  7. RS-232 output available standard.
  8. System accuracy of ±.5% of indicated reading, traceable to NIST.

Options
  1. Non-motorized systems available for production-line bottle cap testing. Model AWS-3000C.
  2. Pneumatic base fixture eliminates all operator adjustments.
  3. Calibration standards for metrology and production line verification. Verify system accuracy without removing the stand from the production line. All traceable to NIST.
Cap and Base Fixtures
Cap and Base Fixtures are designed to grip the bottle firmly, while having no effect on the threads under test. The system, as shown right, consists of a molded cap fixture that is spring loaded to ensure minimal end-loading of the cap during removal. The base fixtures (Automatic fixtures shown), are machined to closely match the profile of the bottle being tested. The fixtures are removable with a single screw for fast and
easy change out. Fixtures are available to grip items as small as a syringe needle, to large gallon (or greater) bottles.

Unique features include:
  • Cap-height sensor. No set-up adjustment for different bottle heights EVER!
  • Interchangeable Torque Transducers allow one
    maching to test your whole product offering.
  • Pneumatic grippers for no-slip holding.
  • Base position sensor returns the base to the same
    start position every time.
  • Self centering jaws never need adjusting: perfect axial
    alignment every time.
Transducerized Bottle

Ideal for checking the capping
torque on the production line, or the verification of your cap testing machine. These transducers are custom made to your enclosure size specification. The bottle is made to match the sample, and a threaded insert is molded into a production cap. Traceable to NIST, this is the simplest and most accurate way to dertermining the torque setting in virtually any capping machine. The torque bottle in equipped with our Intellect circuitry. This makes it compatible with our entire range in displays...including our AWS-2500 series testers. Standard accuracy is 1% of indicated reading. (Bottle here shown connected to our AWS-4050 torque display)
