Supplier typeThe supplier is identified as BOBO Machine Co., Ltd., a China-based limited company established in 2011. Its business is described as a trade company, while other materials present it as a machinery manufacturer and solution provider covering multiple industrial-equipment sectors; this indicates a combined trading and manufacturing-oriented profile.

CertificationsThe supplier’s certification of management systems is explicitly recorded as NIL. Therefore, the provided information does not demonstrate possession of a recognized supplier management-system certification.

After-Sales capabilityThe supplier explicitly describes after-sales service, installation, commissioning, and ongoing support as part of its turnkey and one-stop service. It also states that staff support customers from technical consultation through final inspection and commissioning, providing direct evidence of an after-sales service capability.

Production capacityThe supplier reports two production lines, 6–10 quality-control staff, a 500.0 m² manufacturing plant, and annual outputs of 1,000 sets each for air duct, spring, and PU foam machines. It also reports one-month lead times in both peak and off-peak periods; these figures provide explicit evidence of production capacity, although the scope and verification of the output data are not specified.

Customization capabilityThe supplier explicitly offers turnkey project support, including new workshop layout, investment planning, technical consulting, machine shipment, installation, and commissioning. Its stated one-stop project approach supports customization and project-based configuration, although no specific examples of customized machine designs are provided.

Client casesThe supplier states that customers come from 86 countries, and trade records associate it with SUPRAJIT AUTOMOTIVE PRIVATE LIMITED in India and LAL DIN RICKSHAW PRIVATE LIMITED in Pakistan. These records demonstrate international customer associations, but they do not provide order outcomes, repeat-purchase evidence, satisfaction data, or independently verified case performance.
