Unlike conventional sourcing platforms, Yixinsheng integrates real manufacturing, engineering expertise, and digital automation into one ecosystem. We operate our own facilities while collaborating with over 700 audited partners under unified QC standards. Our AI-driven quoting and DFM tools provide instant manufacturability insights, reducing communication time and production delays. Beyond prototyping and small batches, we support full-scale New Product Introduction (NPI) processes—from design validation and pilot production to inspection and packaging. With dedicated enterprise services, account management, and global logistics, Yixinsheng delivers a reliable, technology-backed manufacturing experience trusted by top-tier companies across medical, automotive, aerospace, and electronics industries.

We provides extensive finishing options for both metal and plastic parts, including anodizing, powder coating, painting, electroplating, brushing, bead blasting, and polishing. Custom colors can be achieved through pre-colored resins or post-finishing with RAL or Pantone references. We also support color consistency verification and gloss level control to ensure visual uniformity across batches. You can explore finish types and examples on our Surface Finishing and Materials pages.

Yes. Upon request, we can provide mill test certificates, RoHS/REACH compliance reports, and third-party inspection documents. For critical applications, dimensional inspection data, CMM reports, and FAI documentation can also be included with your shipment.

Every product goes through strict verification—from trial production and inspection testing to customer confirmation—before shipment. Our quality assurance process ensures that all parts meet the agreed specifications before delivery, minimizing the risk of nonconformities. We take pride in our precision and reliability, and every shipment is the result of a joint confirmation between our engineers and customers.

In the rare event that a delivered part does not meet the agreed specifications, Yixinsheng follows a transparent and responsible after-sales process. Customers can submit a claim with inspection data, photos, or videos clearly indicating the nonconforming features. Our quality team will review the case within 48 hours to identify root causes—whether related to design, machining, material, or logistics.

Based on the assessment, we provide appropriate solutions such as rework, remake, partial refund, or credit, in line with the order terms. All cases are fully documented and backed by inspection records to ensure traceability. To help us resolve issues faster, customers should retain original samples and all supporting evidence. Each case also feeds into our continuous improvement system to further enhance product quality and customer satisfaction.
