Quality control is an important activity in all industries-it and has gained a vital role in the automotive industry because each component required to build the car should be of the highest quality. Cars have to be more reliable since there are individuals' lives involved. As a car producer, you should invest in PDI to ensure that vendors and manufacturers provide you with the best components. In the automotive industry, there is very little room for error when it comes to safety and security.  

Why is PDI Inspection Important?

• • In the automotive industry, quality control is necessary to ensure reliability and credibility. The process can help minimize the cost by ensuring less wastage and no parts are returned. At first, it may seem that investing in high-quality products is expensive. Still, when you compare the potential future cost of recalls or wastage, you may realize that PDI is advantageous to the organization.
• • When you hire the services of reputed PDI inspection firms, you may find that targeted and specific independent inspections can help you fix the problem before the product is marketed to any manufacturers. This would help you to meet the required standards of the automotive industry.
• • Quality control is a cumbersome and challenging process in the automotive industry because it ensures that every part and new model sold to the market built during the entire production cycle complies with standards.
• • During the PDI inspection, prototype models are tested to find any mechanical problems to address the issues which need to be improved or changed.
• • Prototype models are built and tested to find any mechanical problems or issues that need improvement or change. The design will be put into production, and quality control will be carried out on each vehicle after the prototypes have been inspected. Following the completion of the construction work, each car is inspected and tested for any additional issues such as fluid or air leaks or mechanical problems to ensure the vehicle has been correctly assembled.

Automotive parts Inspections

During the PDI services, visual inspections are conducted to look for any issues-ranging from looking for even the smallest defects that could cause accidents or expensive recalls. The cylinder head and block are visually inspected; the focus is on the oil boreholes, cooling channels, and oil lines. Also, brake components are checked, such as the master cylinder, brake calliper, fluid, brake discs, etc.

The quality of the automotive parts helps improve safety and usability, which decreases the risk of recall.

Pre-shipment inspections are crucial to detect any problems that could be spotted and eliminated. It helps in saving time and allows the production line to fix any errors or issues before the client receives the shipment.

Various aspects taken into consideration at this stage are-

• Product Requirements: Matching the prototype to the drawings and client's specifications

• Product Requirements: Matching the prototype to the drawings and client's specifications

• Functionality: To ensure that the device functions properly.

• Markings and Labeling: Accurate labelling must ensure conformity by a certified laboratory or on-site during the inspection.

Supervision is an important part of production, enabling suppliers to evaluate any problem and make relevant adjustments.

Some of the testing methods used in the PDI are:

• • Chemical composition analysis
• • Metallographic analysis
• • Roughness of surface
• • Coating thickness
• • Magnetic powder inspection
• • Hardness testing, tensile strength
• • Yield strength
• • Extensibility
• • Ultrasonic flaw detection
• • X-ray pressure resistance inspection
• • Airtight test and more.

In the past years, the automotive industry has been grappling with issues of recalls. Vehicles are recalled because the vehicles are unsafe or do not comply with the standards and local emission requirements. Some vehicles also do not comply with the standards of manufacturing processes. PDI services help fix the issue and reduce the cost of sales due to brand image impact.
