AI-Powered supplier vetting

SummaryXIAMEN ROCA IMP.& EXP. CO., LTD. is a China-based supplier in Xiamen, Fujian, described variously as a trading company, manufacturer/factory, and group corporation, while another record identifies it as a trading company. Its stated business covers hydraulic cylinders, excavator attachments, metal casting, and hydraulic components, with OEM/custom manufacturing claims. The supplier has 31 employees, valid import/export licensing, 13 years of export experience, and exports representing 71%–90% of total sales. It reports flexible customization and new products launched in the past year. However, it has no available SDK, no in-stock capacity, no overseas warehouse, and no overseas showroom. Certification approval is mentioned in the company description, but no specific certificates are identified. Financial records are referenced by year only, without substantive financial results. Traceability, environmental compliance, fire-drill status, manufacturing-capacity contracts, and customer cases are not...
Supplier typeThe supplier is located in Xiamen, China, and is identified as a trading company in one record and as a trading company/manufacturer/factory among its business-entity classifications. Its company description states that it owns a factory and manufactures hydraulic and metal products, indicating a mixed trading and manufacturing profile rather than a purely documented factory-only structure.
CertificationsThe company description states that its hydraulic cylinders, excavator attachments, metal castings, and hydraulic components have certification approval to meet custom or OEM requirements. Because no certification names, standards, or validity details are provided, the evidence supports a certification claim but does not establish the scope or currency of specific certificates.
R&D capabilityThe supplier reports launching new products during the past year, which is direct evidence of product-development activity. However, it explicitly has no available SDK, so its innovation-related support is not comprehensive across product development and technical integration.
Production capacityThe supplier describes itself as an owned-factory manufacturing enterprise covering hydraulic cylinders, excavator attachments, metal casting, and hydraulic components, and it reports a one-month average lead time in both peak and off-season periods. Conversely, it has no in-stock capacity and its valid manufacturing-capacity contract status is unknown, so production capability is supported but inventory and formal capacity evidence are limited.
Customization capabilityThe supplier explicitly offers flexible customization, and its company description states that its owned factory supports custom or OEM requirements. These two statements directly support its ability to provide customized products.

Product Q&A

Q:What is the advantage of double acting structure for injection molding machine cylinder?
A:
Hydraulic power drives both extension and retraction, the force is stable, which ensures precise mold clamping and accurate ejection distance.
Q:Does it have buffer function?
A:
Standard double-end buffer device to reduce impact and noise during high-speed mold opening and closing.
Q:How is the piston rod treated?
A:
Overall quenching + thick hard chrome plating, high surface hardness, wear-resistant and scratch-resistant.
Q:What are common oil leakage reasons for injection molding cylinders?
A:
Seal aging, high oil temperature long-term operation, piston rod scratches, overpressure overload use.
