In manufacturing, ensuring product quality is paramount. In process inspection or analysis plays a pivotal role in this pursuit, serving as proactive measures to identify and rectify issues before they escalate.
From conforming adherence to specifications to monitoring production stages, it remains highly significant. In this blog, we will take a look at the crucial role of this type of inspection. We will shed light on its methodologies and benefits and the kind of impact it has on overall product quality and customer satisfaction.
What is In Process Inspection in Manufacturing?
Inspection in manufacturing refers to the process of examining and evaluating products. This happens at various stages like incoming, in-process and final inspection, to ensure they meet the required quality standards and specifications.
It involves visual checks, measurements and testing to identify and rectify defects, maintain product quality and prevent faulty items from reaching the market. All these checks ensure customer satisfaction and safety. All these inspections also give us valuable feedback that help to improve the processes and optimisation in the manufacturing industry.
Types of In Process Inspection
These in process inspection procedures are headed by the management team. However, there are usually three types of intervals which decide when this type of inspection is necessary. They are:
- Time-based Intervals:inspection occurs every 2 hours or 2 days. It depends on the equipment you have
- Quantity-Based Intervals: Personnel carries out checking of equipment after a certain amount of output. For instance, In process inspection for every 7 units produced.
- Freely-Defined Intervals: This is discretionary. This can occur at any interval or time.
In-process quality inspections aim to promptly report corrective actions or suggest improvements during ongoing manufacturing. This proactive approach identifies issues as they arise, preventing the need to redo processes.
Implementing an automated in-process inspection system enhances traceability and accuracy, streamlining the inspection process. These inspections, integrated throughout production, mitigate last-minute shipment delays and save valuable time.
Key Aspects of Product Inspection
Product in process inspection encompasses diverse techniques tailored to product type, intended use, and quality concerns. Key aspects include:
A – Visual Inspection: Crucial for detecting visible defects like finishing flaws, labelling errors, or physical damage.
B – Dimension Check: Ensures adherence to size specifications, identifying issues such as incorrect sizing or irregular shapes.
C – Performance Check: Evaluates functional aspects like speed, accuracy, and strength under varied conditions.
D – Functionality Check: Verifies proper operation of features and controls, ensuring intended interactions.
E – Testing Methods: Split into destructive (e.g., stress testing) and non-destructive (e.g., ultrasound inspection) approaches.
F – Inspection Tools: Range from basic measuring instruments to specialised equipment like microscopes and spectrometers.
Let’s see the purpose of inspection in the industrial space.
Need for Inspection in Industrial Manufacturing
Inspections in industrial manufacturing are important to ensure consistent product quality. Due to poor quality leads there is lower customer satisfaction, higher costs for rework and lower revenues.
This is the very reason why companies spend most of their time on solving product issues rather than creating new ones. Therefore, it is crucial to prioritise inspections so you can identify and address any quality concerns at an early stage. This ensures high-quality goods are delivered to customers.
The inspection process in manufacturing has the following advantages:
- Helps Avoid Recalls and Reputational Damage
- Make sure that your products have the required safety for transit
- Recognize Even Small Problems Immediately
- Be sure of the product quality
- Reduce the risk level
With that let’s have a look at the quality inspection methods that companies and supply chain players use to ensure top-quality products.
Process of Inspection
The in process inspection procedure includes several essential steps- defining the standards sampling, methods of inspection, reporting and taking relevant measures. So, let’s see each of them.
1. Define the Standards
Manufacturing businesses have set specific quality standards and specifications for their products. These standards relate to various aspects like dimension, materials, performance criteria, safety requirements and any other relevant characteristics. They help to define the product’s quality and functionality.
2. Sampling
Due to the volume of products manufactured, it is impractical to inspect every single item. Instead, a well-designed sampling plan is used, where a representative batch of products is used to conduct the inspection. With a statistical approach, manufacturers ensure that the sampled products are the accurate representation of the entire production batch or lot.
3. Inspection Methods
The business takes the help of various inspection tactics that the products need. Visual inspection is the crucial tactical procedure they use to assess the product’s appearance and overall condition.
Measurement using precise and calibrated tools ensures that critical dimensions align with the desired standards. For more complex products, there is a need for non-destructive testing techniques. These include ultrasound or X-ray which may help to identify internal defects without damaging them.
4. Reporting and Actions
The last thing on the in process inspection checklist is qualified personnel thoroughly documenting their findings, recording measurements, detecting defects or deviations and conducting a comprehensive evaluation of the product’s quality.
This leads to an inspection report that serves as a record of the product’s conformity to defined standards. Based on the inspection results, authorities will take appropriate actions: products meeting established standards are approved for next-level processing and distribution.
On the other hand, minor defects are under repair or rework to meet the quality standards. Conversely, if significant issues arise or products fail to live up to the standards, you may have to reject the entire batch.
All of these checks certainly have a lot of advantages.
