Supplier typeThe supplier is a Chinese limited company engaged in manufacturing and processing machinery, specifically oilfield tools and equipment. Its stated activities cover research, development, manufacturing, sales, and after-sales service, indicating a manufacturer rather than only a trading intermediary.
CertificationsThe supplier explicitly reports ISO9000 international quality-system certification and current ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates. These certifications provide direct evidence of formal quality, environmental, and occupational-health-and-safety management systems.
After-Sales capabilityThe company explicitly states that its business includes sales and after-sales service for oilfield tools and equipment. However, the slices do not describe service coverage, staffing, response times, spare parts, or warranty terms.
R&D capabilityThe supplier reports a practical and experienced R&D team, more than 40 national patents, five years of R&D-engineer experience, and a stated focus on new products and technology. These claims directly support an established innovation function, although no patent titles or technical performance data are provided.
