AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with substantial manufacturing equipment, a 30,000-square-meter workshop, and stated lifting, machining, heat-treatment, and welding capabilities. It holds ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certifications according to the company description, while another record specifically confirms ISO9001:2015. Service procedures for supplier assessment, corrective actions, and customer complaints are documented and followed, but no approved-supplier list is maintained. The supplier offers extensive customization and ODM services, although it reported no new products in the past year and no available SDK. Export activity is material, with 51%–70% of sales from exports, supported by experienced export staff, but it has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be determined because the provided records contain only years, not financial results or indicators.

Supplier typeThe supplier is explicitly classified as a "Combined" company. The record also describes broad offerings spanning general information, export trade, manufacturing, service, quality control, R&D, and sustainability, supporting a diversified supplier profile.

CertificationsThe company description states possession of ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certification; ISO9001:2015 is separately recorded as a management-system and sustainable-development certification. These records provide explicit evidence of multiple certifications, although the detailed description does not specify validity dates or scopes.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and for handling customer complaints. However, it has no overseas warehouse, showroom, overseas agent or branch, and no offline trade-show participation, indicating limited stated overseas service infrastructure.

Production capacityThe supplier reports a 30,000-square-meter workshop, one production line, a 280-ton single-workshop lifting capacity, large bending and turning equipment, a heat-treatment furnace, and automatic welding machines. Finished-product inspection instructions are uniformly followed, but continuous quantity reconciliation for each batch or production volume is not performed.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization through both design and R&D services. It also offers ODM service, demonstrating broad stated customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and has collaborated with Fortune 500 companies. These are explicit customer-related credentials, although no customer names, project details, product scope, or performance outcomes are provided.

Product Q&A

Q:What raw materials can this welded silo store?

It is specially designed for mine fly ash storage. It can also hold cement powder, limestone powder, mineral powder, feed powder, dry fine sand and other dry powdery & granular bulk materials. The fully sealed tank body prevents moisture ingress and avoids material caking.

Q:Whats the advantage of integral welded silos compared with bolted split silos?

1. Integral full penetration welding, high overall rigidity, wind-resistant and anti-vibration, suitable for harsh open-air mine environments; 2. No assembly gaps, perfect sealing effect, zero dust leakage during feeding and discharging; 3. Thickened steel plate as a whole, long-term full-load storage without deformation; 4. Simple on-site installation, only foundation fixing required, saving construction time.

Q:Is the silo volume and size customizable? Whats the volume range?

Fully customized service is available. The customizable volume ranges from 50m3 to 3000m3. We can adjust silo diameter, height and bottom cone angle according to customers material output, site space and feeding/discharging modes. Single silo or multi-silo group layout are both supported.

Q:What steel material is adopted for the silo body?

The main cylinder, cone hopper and support skirt are made of Q235B carbon steel with high structural strength. For mine sites with high humidity and corrosive dust, we can upgrade to weather-resistant steel or add internal anti-corrosion coating. Mill test certificates of all steel plates are provided for full material traceability.

Q:How to solve blockage and arching problems during fly ash and sand discharging?

The bottom cone adopts large inclined angle design to reduce material adhesion and hanging wall. The silo reserves mounting ports for air fluidization plates, wall vibrators and arch-breaking air cannons. Customers can match corresponding anti-blocking devices according to material characteristics to thoroughly eliminate material bridging, arching and silo blockage. Closed screw conveyors can be matched for fully sealed dust-free discharging.
