The quality control procedures

In order to implement an effective QC program, an enterprise must first decide which specific standards the product or service must meet. Then the extent of QC actions must be determined — for example, the percentage of units to be tested from each lot.

Next, real-world data must be collected — such as the percentage of units that fail – and the results reported to management personnel. After this, corrective action must be decided upon and taken. For example, defective units must be repaired or rejected, and poor service repeated at no charge until the customer is satisfied. If too many unit failures or instances of poor service occur, a plan must be devised to improve the production or service process; then that plan must be put into action.

Finally, the QC process must be ongoing to ensure that remedial efforts, if required, have produced satisfactory results and to immediately detect recurrences or new instances of trouble.

TCD has more than twenty years experience performing quality controls in China

The first step in our cooperation between customer and factory. Assessments and observations help us form the basis for our consulting services. Our experts tour customer’s factory and conduct tests and audits of manufacturing processes, management, and layout.

We offer three different assessment services based on your needs:

  • Facility report
  • Manufacturing process audits
  • Factory improvement plan
  • Production follow up inspections

BASIC SUB-DIVISION QUALITY INSPECTIONS

Manufacturing quality audit (inspection of factory)

A factory audit is recommended to check the reliability of the factory. Guaranteeing quality standards and continuity is important.

A Factory Audit covers the following aspects as standard:

  • Factory Profile description & designation of location. Accessibility to production facility is important.
  • Who are investors of the factory (owner(s), capital, etc.)
  • Organization audit & description production process.
  • Description production lines, machineries, tools, know-how and capacity
  • Other factory facilities & partners.
  • Suppliers of the factory and partners to outsource sub activities.
  • Continuity evaluation.
  • Ability to maximize efficiency / reduction of waste / reuse of raw materials and products.

It is possible to expand an inspection to include:

  • Quality system, certificates, quality standards, quality assessment procedures and certificates.
  • Hygiene & safety.
  • Social responsibility (employees).
  • Supplier inspections / reliability of partners in supply chain.
  • Product development.
  • Ability to make samples, mockups, 3-D printing.
  • Environmental aspects.
  • Packaging and preparations for transport (sustainable solutions for packaging).

First article check – samples inspections (inspection prior to production)

Inspection before starting production.

Before starting production or while starting it, we check the production process to ensure that everything is in accordance with the required specifications and wishes. We adjust where necessary. This checking secures an efficient start and immediately rules out any possible miscommunication.

This part of the inspection is applied when 0 – 10% of the total order is in production or has been produced.

As a third-party inspection company, TCD inspects first-article samples prior to volume production. This inspection in quality verifies that product specifications are being met and avoids unnecessary reengineering work later.

Quality inspection during production process (checkings during production process)

Inspection during production

TCD carries out several checks during the production process to manage the required quality of the goods. This process takes place during 20% – 90% of the production process. The inspections during production process will be strictly follow by quality inspection forms and with necessary measurement tools.

We check the dimensions of the products, visual elements, test functional elements of the products, quality of the raw materials in the production.

We also check the production techniques and how employees perform during the fabrication of products. For electrical products we use measurement equipment-tools and measurement reports. 3W2S

See example of test checking report.

Pre-shipment inspections (Final checking and packing inspections to avoid damages during transport)

The pre-shipment inspections (PSI) are the final quality check of the production process. The pre-shipment inspection is basically carried out to see if the packing procedures are followed according to customer’s protocols. Packing is an important matter to avoid damages. TCD goals are using sustainable packing materials and avoid too much packing materials which may cause too high shipping volumes and costs. TCD check labeling of products and packing.

During a pre-shipment inspection, our engineers verify that finished goods conform to customer’s specifications. A pre-shipment inspection (PSI) generally occurs when production is 100% complete and packaging is 80% complete. For example, if an Automotive Product or Auto Part Inspection is required, we would request your specifications and golden samples in advance and use them to ascertain the quality of the products produced at supplier’s facility.

Container loading inspections – shipment inspections (FCL or LCL) (supervision during loading container or shipment to check quantities)

TCD ensures that proper methods are employed during product loading, and we verify counts on-site. This also involves checks to ensure that all the goods you have ordered are being loaded. TCD uses special software program to calculate the placing of packed products in containers (easy cargo).

TCD seals the containers before leaving to the warehouse of the forwarder’s terminal.

Extensive processing checking – extensive end product inspections (inspections carried out by Customs or third parties for approvals or certifications)

Custom inspections / audit

This support is adjusted in accordance with customer’s wishes and needs. TCD provides with follow-up advice in the case of complex matters and issues, so that customer’s interests are represented. Extra Customs checks may occur in China causing delays. TCD supports personally with our extensive experience and expertise in quality, purchasing, but also in the field of China itself. In this way, we work to improve the production process, with an eye on the relationship between the customer and the factory; the long-term relationship is our primary concern.

Thanks to personal supervision and by making use of our knowledge and expertise, we can offer the best quality control in the integral production process.
