AI-Powered supplier vetting

SummaryTianjin Haorongshengye Electrical Equipment Co., Ltd. is identified as a China-based limited company established in 2008, with 20 employees and operations in Tianjin. The available information presents it as a manufacturer and exporter of mechanical transmission products, including gears, racks, sprockets, roller chains, and timing pulleys, supported by 10 production lines and stated CNC, measurement, and heat-treatment equipment. It reports export markets across multiple regions and lead times of within 15 working days in both peak and off-peak seasons. The company states that it follows CE and ISO 9001 standards and offers bespoke solutions, but the provided slices do not include certificate documents or detailed after-sales procedures. Its company classification is also described as a trade company in one record, creating some ambiguity regarding its operating model. Customer-trade evidence is limited to two transactions associated with one Ukrainian buyer.

Supplier typeThe supplier is legally presented as Tianjin Haorongshengye Electrical Equipment Co., Ltd., a Chinese limited company established in 2008. Its profile describes it as a professional manufacturer and exporter, while another record classifies the company nature as a trade company; therefore, the evidence supports a manufacturer/exporter profile but also indicates an operating-model inconsistency.

R&D capabilityThe company reports three R&D engineers, offers bespoke solutions, and has introduced CNC hobbing, machining, grinding, broaching, measurement, punching, and heat-treatment equipment. This supports product-development and engineering capability, although the slices do not document patents, new product launches, R&D investment, or specific innovation outcomes.

Production capacityThe supplier reports a 220.0 m² manufacturing plant, 10 production lines, fewer than five quality-control staff, and advanced manufacturing and testing equipment. It also states that peak- and off-peak-season order fulfillment is within 15 working days, indicating operational capacity, although the relatively small stated plant area and limited QC staffing should be considered when assessing scalability.

Customization capabilityThe supplier explicitly states that it offers bespoke solutions, and its described design, development, production, CNC machining, measurement, and heat-treatment capabilities are directly relevant to customized mechanical transmission products. The slices do not specify customization limits, engineering workflows, prototype capability, or minimum order requirements.

Product Q&A

Q:What customization options are available?

We offer customization for Module (M1-M10), Length (500mm/1000mm/2000mm), Teeth Type (Straight/Helical), Precision Grade (DIN5-10), and Color (Black/Natural/Custom).

Q:What materials are used for the gear racks?

Materials include C45 steel, 304SS, 316SS, 40CrMo, nylon, and POM, with options for high-frequency heat treatment and surface hardening.

Q:How are multiple gear racks connected?

Standard racks have half-tooth ends for smooth connection. We recommend locking bores first, using a tooth gauge for accurate pitch alignment, and finally locking position pins.

Q:What is the lead time for orders?

The average lead time is within 15 workdays for both peak and off-season periods.

Q:Do you accept OEM orders?

Yes, we accept OEM services and can customize products according to your specific drawings and requirements.
