Process Engineering
Operational or production process
A business or operational process is an organized set of activities or tasks that produces a specific service or product. Nowadays, there are different types of production processes that businesses can use depending on predetermined goals such as production capacity, technology, quality levels, and so on. Therefore, it can be said that the ultimate goal of production process designers is always to develop production processes so that the methods and steps required to produce the product or products, always cover the quantitative and qualitative indicators defined for the optimal process.
Traditionally, OEM (Original equipment manufacturer) have production lines for car production in the following halls*:
* Above mentioned information is based on most OEMs that APQ has cooperated with, so many auto makers may have other halls to build and assemble some other components such as engines, suspension systems, seats, etc. or vice versa, some of the production lines mentioned above, can also be outsourced.

BIW assembly lines and APQ
Although the transfer systems of this company have many applications in painting and final assembly halls, but the specialized activity of APQ company in the field of Automotive is specially structured in body in white assembly halls based on the required systems.The specialists of this company, some of whom have more than 20 years of experience in the field of engineering and designing the systems required in body in white assembly shops , have been responsible for engineering the production processes of several car bodies before and after cooperating with this company, and the results of their positive activities have made our customers trust us in this field more. |

BIW assembly Process
BIW assembly processes and instructions are divided into the following main categories depending on the design and type of assembly lines:
- Independent
- Dependent

Independent BIW processes and instructions
Nowadays, car manufacturers use different car production process specialists in the main product design team to develop a new car and to avoid possible problems, and it can be said that due to the importance of car body assembly processes, the presence of experts in this field is more serious than others. The main task of these specialists is generally to continuously review CAD data of parts according to the required functions, report construction and assembly problems to designers and provide corrective solutions to solve them. Obviously, the problem-solving process may be repeated several times to finalize the design of some parts or assemblies. Simultaneously with the finalization of the above-mentioned CAD data, the car body assembly process specialists also prepare the following procedures and documents, which, after finalization, will be used as reference procedures for the development and Manufacturing of car body assembly lines.

The above procedures and documents are not specific to any production line, and the outline of all assembly lines that are made for the body of this particular car must be based on these references to avoid any geometrical or quality problems.
These are called independent procedures and processes.
Dependent BIW processes and instructions
Despite the same references above for all body lines made for a particular car, the body assembly lines created are in many cases different due to factors such as capacity, level of automation, etc., and unique processes for each of them is compiled by experts.
Since these processes and procedures are formulated according to the requirements of the production line, they are called dependent. In developing the body assembly process of a car, usually the following activities are performed as a standard procedure by APQ, unless the project conditions are defined differently by the employer.
BIW Process in APQ
Since the specialists of APQ -with more than 20 years’ experience-have been directly responsible for new cars production process engineering during their years of development and design of several new products, so in addition to developing existing car production processes for new production lines, APQ can also Cooperate with New cars development teams and can provide them necessary engineering services in the field of car body assembly issues such as welding and assembly possibilities, locating and clamping procedures, tolerances stack up analysis and so on. For more guidance, you can refer to APQ.
