1. What is quality control? How it could improve your products quality and benefit your production business?

Quality control (QC) is the key to establishing a successful business and is a segment that plays a crucial role in the manufacturing process.

The term quality improvement can be approached from various perspectives and implies the required specifications that are fulfilled and the product manufactured is functioning as expected. From raw materials to finished products, QC is in every step of the manufacturing process.

All the acts of inspection, including measuring, examining, and testing one or more characteristics of a product or service and then, comparing these with specified requirements, are to ensure that the product coming off a production line, or the service is correct and meets specifications.

QC inspectors protect the consumer from defective products and the company from damage to its reputation due to the manufacturing processes. In other words, not only the customer satisfaction and trust are guaranteed, but also the positive image of the company is also protected. By undertaking effective inspection and control over production processes and operations, it can help the company to save their production costs, enable the optimum utilization of the available resources, and of course, enhance efficiency.

In addition, practicing quality control also has a positive impact on employee conduct. It can inspire employees to create high-quality goods that leading to greater customer satisfaction. In short, when a company puts reliable quality control in place, it not only the money and resources that they can save, but also the time.

2. Types of QC in manufacturing

Described as such, quality control remains rather vague. What we have witnessed in South East Asia through our years of experience at SOA is that there are several visions and steps in quality control management that are regularly taken into account. Following the process of manufacturing from the beginning to the ending, every step always has a QC inspection way to proceed and follow.

Depending on the countries, the customer presence, the sensitivity of products, and the relation with suppliers, all of these quality controls can be implemented totally or partially. It is not rare to see buyers handling directly with the manufacturer for the pre-production sample, as well as in-line & out-line inputs, and then deciding to hire third parties to conduct final inspections and/or testing.

  • Pre-production sample

Before launching the mass production, a step of preparing and manufacturing samples is always in need, as it often sets the base for all future quality control. All kinds of samples such as AKA sample, master sample, or counter sample, sometimes undermine, but yet is a key factor to control the quality and to better communicate with all parties.

  • Technical inspection

Also known as laboratory testing, this kind of inspection is mainly carried on picked items from the production (or, sometimes, pre-production samples) to conduct more thorough and deeper, or simply technical tests requiring machines or complex techniques.

  • In-line inspection

Instead of checking the quality of the product at the end of the manufacturing process when the product is completely made, the company should do the checking at certain milestones of the process. It is how the inline inspection works. If there are any defaults or the quality isn’t good enough, this method could help factory management and supervision proactively to take necessary precautionary measures and easily identify the root cause.

As result, the problem is rectified, the preventive measures (or corrective plans) are established to avoid future recurrence, and more importantly, the factory can avoid the fact that the full batch of production is rejected at the end of the production. In fact, in the textile industry, inline inspection is quite important.

For instance, if the final inspections show a defect, it is hard to provide a corrective plan and fix the problems. Because it is very costly (in terms of time, raw materials, and cost) to revise a production, as the products cannot be fixed and need to be re-manufactured 100%.

  • Out-line inspection

Out-line inspection is usually conducted at the same time or in a similar way as the in-line inspection. The inspection controls the first pieces of the finished product when it is out of production. With the same benefits and possibilities as the in-line inspection, it offers more flexibility in implementing corrective plans.

  • Final inspection

The final inspection is the last opportunity for auditors to catch and address quality issues before they end up in the hands of the buyer, or even worse, the consumer. It is usually conducted when 100% of the purchase order is manufactured, and 80% packed, it gives the green light (or doesn’t) for purchase and shipment.

During the final audit, products are examined for specific performance requirements, taking into consideration all criteria such as function, dimensions & weight, finishing, usage, technical, packing, labeling, etc.

  • Loading inspection

It is not obligatory but rather a necessary step to complete the whole manufacturing and shipping of the order. The purpose of this inspection is to make sure that the goods are properly handled and safely loaded into the shipping containers for a secured transportation.

Depending on the sensitive values, the risky areas, or other doubts, it is an additional control of the loading itself of a container or cargo, and the validation that it matches what was requested.

3. Quality control service at SOA

  • Our expertise and services

Standard quality control management can establish well-defined controls and help to standardize both production and reactions to quality issues. As a buying office & sourcing company, our role usually extends further than that. We help smoothen the process by implementing each of the quality controls ourselves and increase the chances of passing the final inspection in the end.

In order to do so, we have evolved over the years. From the merchandisers conduct the quality control management by themselves at the early start of our company, to the cooperation with the third parties and external experts at some key phases of the manufacturing process, we finally decided to build and strengthen our internal quality control division with our own team.

By developing our own quality control crew, we are able to expand our knowledge about the products at every step of the supply chain. We also take the responsibility to predict, detect, and address any issues, to both suppliers and customers that may arise from the beginning of the manufacturing process. Not just simply giving the client a snag list (what is passed, pending, or failed), we even input our recommendations and solutions to our customers and suppliers to work on the problems and fix them.

A key step for us to set this up, is a good and strong understanding of our customer’s expectations. Not only following the internationally known AQL (Acceptable Quality Limit) method, we are also able to adapt and implement different quality control standards, depending on each customer’s requirements, expectations, profiles, and products.

  • Our specialty

At the present, our quality control division has more than 20 years of experience and the team is able to demonstrate its essential position in the supply chain. The QC process at SOA is built professionally based on international standards and several years of experience working in many categories and products (such as furniture, home décor, textile, spare parts, etc.). The quality of the product would be controlled by SOA’s involvement from the beginning to the end of the manufacturing process, and ensured to match the requirements of our customers and the capacity of the factory.

We not only control the quality of products but also evaluate the factory we cooperated with. The factors such as the factory’s strengths and weaknesses, its capacity and liability, etc. are well-considered.

In summary, at SOA QC services, we have built our own process with detailed steps and regulations which ensure to be followed and done by all the involved departments from merchandiser to the quality controller. It must be noted that the importance of good collaboration between a quality controller and a merchandiser following tightly the process would create a professional procedure and lead to the best results.
