We’ve been sourcing forged and cast components from SQM since 2019, and they’ve proven to be an extremely reliable partner. We operate in the agricultural machinery sector, where durability and consistency are key for us. SQM has always delivered on time, with components that meet our technical drawings and quality expectations. Their engineering team is very responsive, and they’re always open to suggestions for improvement. In fact, when we faced issues with dimensional tolerances in early prototypes, they quickly provided corrective actions and new samples within a couple of weeks. We value their transparency and professionalism. It’s not easy to find a Chinese supplier that combines competitive pricing with strict quality control, but SQM manages to do both. Highly recommended.

SQM is one of the few suppliers we truly trust. SQM has delivered thousands of units for our trailer axles and suspensions to us with minimal defect rates, always backed by proper material certifications and dimensional reports. We were initially cautious about working with a supplier so far away, but their communication has been excellent, and their ability to handle complex part geometries has exceeded our expectations. They even helped us redesign a part to reduce machining time, saving us both cost and time. We’ve visited their foundry and machining plants in China, and they are clean, well-managed, and ISO-certified. We’re now expanding our cooperation to more parts.

As a company producing high-performance industrial pumps, we demand very precise cast components and surface finishes. SQM has consistently delivered sand and investment cast parts that meet our specifications, even when the tolerances are tight. We appreciate how hands-on their quality control team is, each batch is accompanied by detailed inspection reports, and they’ve adapted their processes to meet our internal standards. Lead times have been stable, and they’ve helped us avoid downtime more than once with fast shipments. Their team is responsive, speaks excellent English, and understands European compliance requirements. They’ve become a key part of our supply chain.

We’ve worked with SQM on several cast and machined components for offshore applications. Their team handled our 3D models, casting simulations, and prototype development very professionally. We’ve had zero major non-conformities since working with them. I was particularly impressed by how they adapted to our packaging and labeling standards without hesitation. Having a single partner that covers casting, machining, and surface treatments simplifies our procurement process significantly. SQM is not just a supplier for us, but a technical partner.

SQM is our preferred supplier for cast and forged parts. From the beginning, they showed strong technical understanding of our parts in the rail industry, which include tight tolerances and specific heat treatment requirements. Their ISO certifications gave us confidence, and the actual performance has matched their documentation. They are proactive with quality, we receive PPAPs and material test reports before each shipment, and they haven’t missed a delivery deadline in over two years. Even during the COVID disruptions, they managed logistics better than some of our local suppliers. It’s rare to find a supplier from China that combines engineering expertise, cost-effectiveness, and punctuality at this level. It also helps that they have company and warehouse in Germany.
