After over 30 years in business, we know what it's like for customers to be on the receiving end of sub-par products, and see projects scuppered as a result.
That's why we're determined never to let that happen to a Sanwei client.
Our quality control checks are second to none. In fact, we're often trusted by long standing customers to audit, monitor and manage their proprietary supply bases in Asia, such is the level of confidence in our systems, work ethic and integrity.
Our entire supplier network is thoroughly vetted by Sanwei, and is ISO 9000 and ISO 14000 quality assurance certified as a minimum. For machinery and items where product certification applies, our suppliers must apply industry standard quality control checks and retain all appropriate technical files.

Beyond products
At Sanwei, we recognise that quality control extends beyond the products themselves. We also care deeply about:
Environmental considerations
We insist that our suppliers:
- Comply with all applicable environmental laws and regulations
- Recognise that environmental responsibility is integral to producing high quality products
- Minimise adverse effects on the environment and natural resources
- Commit to a culture of continuous improvement, to conserve resources, prevent pollution, and minimise adverse impacts to people and communities
Ethical considerations
Sanwei is committed to conducting business in accordance with the highest ethical standards and in compliance with all applicable laws. More information can be found in our code of conduct.

We ensure that our dedicated quality control team performs rigorous checks on all orders, including:
- Incoming material inspection
- Quality checks on all processes
- First article approval
- Small batch production to check quality consistency
- Pre-shipment inspection
- After sale warranty
- Quality auditing to IATF16949 (where applicable)
- Using APQP, FMEA, SPC and Poka-Yoke process
