AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier engaged in aerospace components, molds, stamping parts, hardware, automation equipment, production lines, and industrial robots. It provides 3D software design, ODM, OEM, and multiple customization options. Evidence also shows new product development, cooperation with colleges and research institutes, and a sheet-metal forming technology research base. Service management procedures cover corrective actions, customer complaints, supplier assessment, and quality assurance. However, the supplier lacks an available SDK, overseas agents or branches, overseas warehouses and showrooms, in-stock capability, and a valid manufacturing-capacity contract with related subcontractors. An ISO9001:2015 certificate and regular fire drills are reported, but no factory environmental impact assessment report is available.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers aerospace product components, molds, stamping and hardware products, automation equipment, production lines, and industrial robots, indicating a technically oriented manufacturing and engineering profile.

CertificationsThe supplier reports holding an ISO9001:2015 certificate, which provides explicit evidence of a quality management certification. However, the available information does not establish other certifications.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, and its overseas service offerings include installation, training, repair, maintenance, and debugging. Nevertheless, it has no overseas agents or branches, no overseas warehouse or showroom, and no in-stock capability, which limits the breadth and local responsiveness of after-sales support.

R&D capabilityThe supplier provides 3D software design, has developed new products during the past year, offers ODM services, and describes cooperation with colleges and research institutes, including a sheet-metal forming technology research base with six professors and postgraduates stationed long term. The absence of an available SDK is a limitation but does not negate the documented product and process innovation activities.

Production capacityThe business scope includes manufacturing aerospace components, molds, stamping and hardware products, automation equipment, production lines, and industrial robots, with stated average lead times of within 15 working days in the off-season and one month during peak season. However, the supplier reports no in-stock capability and no valid manufacturing-capacity contract with its related subcontractor, so production capacity is supported but not comprehensively verified.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also provides 3D software design and ODM services, directly supporting a broad customization offering.

Product Q&A

Q:How does your metal stamping mold ensure minimal burr height on thin silicon steel sheets?

We employ sub-micron optical profile grinding and EDM machining to maintain an optimal cutting clearance ratio (3% to 5% of material thickness). Coupled with tungsten carbide inserts, burr heights are maintained under 0.015 mm for millions of strokes.

Q:Can the progressive mold perform automatic interlocking and skewing for EV motor rotors?

Yes. Our advanced progressive molds can be built with integrated pneumatic or servo-driven indexing units. They perform automatic interlocking, counter-boring, and angular skewing inside the mold to deliver fully assembled rotor cores directly off the press.

Q:What maintenance routines are required to achieve the guaranteed 100+ million stroke die life?

Regular sharpening (re-grinding 0.05-0.10mm off punch faces every 3-5 million strokes) is essential. We provide precise sharpening limit indicators on all punches and include complete grinding allowances in our technical manual.

Q:How do you verify the coaxiality and dimensional accuracy of stator core samples?

We perform 100% CMM inspection, air gauge tolerance testing, and iron loss (core loss) electromagnetic testing on T1 sample stacks before dispatching them along with full inspection certificates.
