20105112175_a6eb8b1539_z

If you listen to any conversation or news report related to manufacturing, you’re likely to hear the terms ‘Quality Assurance’ and ‘Quality Control’ tossed around more than a few times. But do you know what these terms really mean and whether there is a difference between the two? If you find yourself admitting that you’re not quite sure, then you’re not alone.

Although often used interchangeably, the terms Quality Control and Quality Assurance refer to two distinct processes that are essential components of any successful manufacturing operation. Here’s how the two compare:

The Keep-nut anchor is available in a variety of models for different applications.This example shows a Keep-nut anchor installed in Corian, which is solid surface material made from acrylic.

Drill a hole using the recommended diameter bit. It is very important that the hole is drilled to the correct depth for the particular model being used. A stop collar is recommended to achieve consistent results. The drilling of the holes can also be easily automated using CNC routing equipment for faster processing. Diamond drill bits are available for preparing holes in granite, marble or engineered stone products.This shows a completed hole.

The hole can then be tested using the Keep-nut Gauge to ensure correct depth and diameter.This is a keep nut fastener next to prepared hole.

The fastener is then threaded onto the optional setting tool. The setting tool installs the Keep-nut easily and accurately while reducing the likelihood of striking the panel directly with the hammer and causing damage.The fastener is then installed using a mallet or hammer.

The Benefits of QA and QC
Implementing Quality Assurance and Quality Control processes, or even just elements of them, give manufacturing companies the ability to save on time, money, and labor. Having a tight grip on QA often means fewer mistakes and losses that employees need to correct or compensate for during or even after the QC phase. And this, in turn, results in quicker turnaround time and enables manufacturers to continue to produce the high quality products that consumers are expecting.

One important thing to remember about QA and QC is that they’re ongoing processes that, at the core, focus on the end goal of customer satisfaction. In creating a constant stream of quality products that customers can rely on, manufacturers are simply doing their part in fostering positive relationships with the people who buy from them, which inspires a very strong sense of customer loyalty that makes mutually beneficial transactions possible.
