How should cap torque range be matched with cap specifications on a commercial capping machine?

Test actual caps and bottles because thread geometry, closure material, and liners can change the required tightening torque. A sample demonstration is useful, but continuous production data is needed to verify repeatability and practical capacity. The supplier should identify any capacity limit caused by product temperature, moisture, particle size, or other material properties. For critical parameters, require signed records from both parties and retain the original data with the order documents. For equipment with change parts, list every required component and its adjustment range before placing the purchase order.
