AI-Powered supplier vetting

SummaryQingdao Guanshan Industry Co., Ltd is identified as a China-based limited company in Shandong, with conflicting classifications as a trading company and manufacturer/factory. Its stated business covers plastic and rubber product processing, manufacturing, and wholesale. Evidence indicates production equipment, flexible customization, ODM services, and OEM services for well-known brands. Service procedures, corrective-action procedures, and complaint-handling records are reported, while peak- and off-season lead times are within 15 working days. However, the supplier reports no new products launched in the past year, one R&D engineer, no SDK, no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Certification holdings, customer cases, raw-material traceability, and fire-drill status are not sufficiently evidenced. Financial information is referenced for multiple years, but the provided slices do not establish financial strength.

After-Sales capabilityThe supplier reports written procedures and implementation records for service-capability assessment, corrective and preventive actions, and customer-complaint handling. It also states lead times within 15 working days in both peak and off-season, but the evidence does not specifically describe warranty, repair, replacement, or post-delivery support.

R&D capabilityThe supplier provides ODM services, but it reports only one R&D engineer, no available SDK, and no new products launched in the past year. The explicit absence of recent product launches and the limited stated R&D resources indicate a deficiency in demonstrated innovation performance.

Production capacityThe supplier states that it has two automatic auxiliary-machine rubber mixing centers, two precision rubber mixing centers, four large foam vulcanization production lines, and large coating machines. Its declared processing and manufacturing scope covers plastic and rubber products, and it is also identified as a manufacturer/factory, providing explicit evidence of production infrastructure.

Customization capabilityThe supplier explicitly offers flexible customization and ODM services, demonstrating both customized design/manufacturing availability and stated flexibility. OEM service for well-known brands further supports its ability to produce according to customer or brand requirements.

Product Q&A

Q:Can I get samples of different densities?

Yes, we provide free A4 size samples; you only need to provide a courier account number for shipping. Special color samples may take longer and incur charges.

Q:Can I buy small quantities?

Yes, we accept small orders. We will calculate production and transportation costs based on your size and quantity. Additional costs can be reduced if you buy multiple models simultaneously.

Q:Can you use carton box packaging?

Yes, we can customize cartons with your logos and text. We calculate carton sizes based on EPDM foam density to minimize individual carton size, using double corrugated design.

Q:Can you offer cutting or die-cutting services?

Yes, we provide cutting and die-cutting services. Please provide drawings, dimensional requirements, and performance specifications for pricing. We can also sign an NDA.

Q:What are the available customization options?

We offer customizable density (110-220 kg/m3), hardness (5-30 Shore C), color (White, Blue, Grey), tensile strength, and thickness (2mm-50mm).
