It operates six production lines, employs 6–10 quality-control staff, and supplies diesel and natural-gas engines, engine components, hydraulic pumps, and related products. Its stated export coverage is broad, and it supports FOB, CIF, and CFR quotations, with LC and T/T payment terms. Off-peak lead time is within 15 workdays, while peak-season fulfillment is stated as 2–3 months. The company reports 15 years of R&D engineer experience and nine years of staff experience, but no certification information is provided. Trade records show limited documented transactions: three Brazil-related records from March–April 2025 involving two buyers and products including a connecting rod and carbon-related item. After-sales service and customization capabilities are not sufficiently documented.

R&D capabilityThe supplier reports 15 years of total R&D engineer experience and describes continuous development, innovation, and advancement as company objectives. This supports the presence of stated R&D experience, although no specific innovations, patents, or developed technologies are documented.

Production capacityProduction capability is supported by 114 employees, a 26,000 m² manufacturing plant, six production lines, 6–10 quality-control staff, and an off-peak lead time within 15 workdays.

Client casesDocumented trade records identify two Brazil-related buyers, LUPIN IMPORTACAO&EXPORTACAO LTDA and DUAUTO DISTRIBUIDORA DE AUTO PECAS LTDA, across three transactions recorded in March and April 2025. These records provide concrete customer evidence, but the small number of transactions limits the breadth of the demonstrated customer portfolio.
