Defining Quality Standards Through Precision Inspection – The Strategic Value of Our 2022 CMM Investment
As a professional tablet press manufacturer with over 40 years of industry experience, Shanghai Tablet Press Mechanical Components Co., Ltd. has always regarded precision as the lifeline of its equipment. In 2022, the company completed a major strategic technology upgrade – the introduction of a high-precision Coordinate Measuring Machine, which has been fully integrated into the machining and final inspection processes for turret mold bores. For commercial confidentiality reasons, this investment was not disclosed at the time. Today, we are sharing this information to help our global customers better understand why our tablet presses carry a justifiable cost premium – and why that premium represents an uncompromising commitment to product quality.
The turret is the core component of any tablet press, housing the upper punch, lower punch, and die. The three-dimensional positional accuracy, diameter tolerance, roundness, and perpendicularity of its boreholes directly determine punch alignment, motion stability, and ultimately, tablet weight uniformity and hardness consistency. Even micron-level deviations can be magnified during high-speed operation, leading to abnormal tool wear, increased vibration, and even batch-wide product rejection.
The introduction of the CMM has given us micron-level three-dimensional inspection capabilities. Unlike conventional gauges, the CMM performs full-contour scanning and digital modeling of each borehole, automatically generating detailed reports covering positional deviation, coaxiality, perpendicularity, and other critical parameters. This technological upgrade, however, comes with a hidden cost: with significantly tighter inspection criteria, the rejection rate during machining has increased substantially. Components that might have passed traditional checks are now strictly eliminated, resulting in a lower overall yield and a higher per-unit manufacturing cost.
Our management team firmly believes that this is a necessary cost for quality – not a loss of efficiency. Every rejected part identified by the CMM represents a potential machine that will never underperform in the field. For our customers, this translates into more stable machine operation, longer tool life, and tighter tablet weight control during high-volume production. This proactive approach to raising the bar is exactly how we honor our commitment to delivering long-term value to our customers.
It is also important to note that the CMM is not an isolated investment but an integral part of our precision manufacturing ecosystem. Since establishing our in-house mold workshop and equipping it with advanced CNC machinery in 2015, we have been systematically building a fully integrated quality control chain – from blank machining and finishing to final inspection. The data feedback from the CMM also guides continuous process optimization, helping us achieve unprecedented consistency in borehole machining.
Today, when customers ask about our pricing structure, we can give an honest answer: part of the cost comes from the components that never left our factory – and it is precisely those eliminated parts that uphold the trusted quality reputation of every machine we deliver. Going forward, we will continue to leverage precision manufacturing and rigorous inspection as our twin pillars, providing the global pharmaceutical, food, chemical, and nutraceutical industries with tablet press solutions that truly stand the test of quality.
