7 Advantages of the Assembly Quality System (AQS)

Published: Jitty Geerts

When outsourcing the production of a mechatronic machine or module, you of course expect a perfectly functioning product that meets specifications and requirements. By employing the Assembly Quality System (AQS), MTA secures the monitoring and registration of quality during the entire assembly process, including the test- and delivery procedure.


The vast majority of all information that is needed to assemble a machine or module is recorded in the technical product documentation (TPD). For example, the engineering drawings are included in the TPD. Yet, specific types of information that are vital to the production process often remain undocumented in these recordings. Therefore, MTA developed the Assembly Quality System (AQS).

In this digital quality system, checkpoints specifically for customers and the project are documented. Examples are intermediate measurements of product dimensions or tolerance levels of certain parts. The visual finish of the module may be another relevant aspect. Moreover, the system can prescribe the use of certain tools. Besides this, serial numbers of parts are registered to be able to trace the parts’ origins.


The AQS is a unique system conceived and developed by MTA. With this system, MTA targets the so-called ‘high mix, low volume’ market, referring to an environment that is characterized by a great variety in customized modules and machines which are produced in relatively low quantities. This quantity may vary from a few machines to 1,500 machines annually. MTA feels at ease in this territory: we are used to working with highly differing types of production. We possess extensive knowledge in the realm of mechatronics because of this diversity. In this, the AQS is a unique, fully digitalized tool that sets us apart as a system supplier.  

Employment of the AQS brings many advantages. Keep on reading to find out about these benefits.

advantage #1: ensuring consistency

Consistency of assembly is guaranteed due to the fact that the assembly instructions, specifications and requirements are fully documented. The production no longer depends on individuals, and a uniform result is assured.


advantage #2: digital availability

In the AQS, every bit and piece of information is documented digitally. This digital production directory is carefully saved after completion of the assembly process, meaning this document is readily available in the case of follow-up orders. Additionally, when a problem regarding a certain module arises later on, it is possible to consult the document. Serial numbers of individual components are registered in the AQS, enabling MTA to easily trace the origin of specific components. This allows for targeted problem solving.


advantage #3: Feedback tool

The mechanics who assemble the module or machine use the tool to provide other departments with feedback. This AQS feature results in a simple, targeted and efficient interaction between mechanic and engineer. The feedback posted by the mechanic may be used to improve the production of the module's future series.


advantage #4: Always up-to-date

The information included in the AQS is always up-to-date. Edited or added pieces are directly digitally available, also for the mechanic. Outdated information is removed from the system once the new information is added. By doing this, MTA prevents the mechanic from working with incorrect information; a considerable risk that is present when working with softcopy assembly instructions of which outdated versions may remain in circulation on the shop floor.


advantage #5: registration of issues

In addition to the previous advantages, the AQS operates as a trouble shooter when testing the modules. In case a component does not function (as expected), the mechanic can use the AQS to research whether this problem has already occurred in the past, and what can possibly be done to solve it. Consider it a documentation platform that includes FAQ’s with which a solution can be found quickly and efficiently. Of course, we inspect the root cause of issues that occur often to prevent these problems from happening once and for all.


advantage #6: Improving efficiency and productivity

Displaying the information in a clear and structured way enables the mechanic to quickly and efficiently carry out the assembly process. Real-time monitoring and registration of quality during the assembly process significantly contributes to this. By incorporating intermediate checkpoints, MTA prevents problems from arising during the functional test at the end of the process. Possible problems are signaled during an early stage of the production process, enabling anticipation. By doing this, MTA prevents the necessity to disassemble (part of) a module to solve an issue. This saves a lot of time, and this naturally contributes to an attractive price for the customer.


advantage #7: customized information
Sometimes, an OEM'er possesses its own quality control documents; these recordings can be easily integrated in the AQS. In this way, the customer receives predetermined, customized information regarding for example test results and specifications of the module.


case study: quality approved

Vanderlande Industries chose MTA as their partner for the production of STACK@EASE. The AQS significantly contributed to the assembly process, resulting in a state of the art end result.
