About Jinan Hengruijn Testing Machine Co., Ltd. - Light & Medium Machinery Supplier in China

China‑based Jinan Hengruijn Testing Machine Co., Ltd. lists five active products in its catalogue. The company focuses on Light & Medium Machinery and Scientific Instruments, with a specific emphasis on testing equipment for geotextiles and universal material testing. All five models are computer‑controlled machines that target laboratory and field testing applications. The product titles include two geo‑textile testers (WDW-20 and WDW-30) and three universal testing machines (WDW-2 single arm, WDW-2 electronic, and WDW-3 electronic).

Product Range and Specialties of Jinan Hengruijn Testing Machine Co., Ltd.

The catalogue covers computer‑controlled geo‑textile testing units and electronic universal testing machines. In the testing‑machine market, buyers typically evaluate load capacity (often 0‑20 kN for light machines), displacement resolution (0.01 mm or better), and compliance with ISO 7500‑1 for force measurement accuracy. Common specifications include servo‑motor drives, digital read‑outs, and optional software for data acquisition. These machines are usually built with steel frames, calibrated load cells, and safety interlocks to meet laboratory safety standards.

Trade and Export Information - Jinan Hengruijn Testing Machine Co., Ltd.

Testing machines from China are classified under HS chapter 84, code 8429, which covers "Other measuring, checking, testing or analysing machines and apparatus". Export shipments frequently use 20‑ft or 40‑ft containers with wooden crates or metal pallets, and buyers often request CIF or FOB terms. Major import regions for such equipment include Southeast Asia, the Middle East, and Africa, where construction, mining, and agricultural research drive demand. Typical buyer requirements involve CE marking, ISO 9001 quality‑management certification, and a test report confirming compliance with relevant standards. Chinese manufacturers commonly provide pre‑shipment inspection reports and factory‑issued calibration certificates.

Sourcing from Jinan Hengruijn Testing Machine Co., Ltd. - Buyer Guidance

When sourcing these machines, request the latest calibration certificate for the load cell and a copy of the CE Declaration of Conformity. Verify that the machine’s load capacity, control accuracy and software interface match the specifications needed for your testing regime. Ask for a single‑unit sample or a demonstration video, and confirm packaging details such as crate dimensions and moisture‑proofing before shipment.

What testing functions do the WDW‑20 and WDW‑30 machines provide?

Both models are designed for geotextile tensile testing, offering computer‑controlled load application and data logging in accordance with ASTM D4595.

Are the universal testing machines capable of compression testing?

The WDW‑2 and WDW‑3 units are primarily tensile testers, but they can be equipped with compression fixtures that meet ISO 7500‑1 load‑cell accuracy requirements.

Which HS code applies to these machines for customs clearance?

They fall under HS code 8429, the category for other testing and measuring apparatus.

What certifications should a buyer request before purchase?

Buyers should ask for CE marking, ISO 9001 compliance, and a recent load‑cell calibration certificate issued by an accredited laboratory.

What is the typical packaging for shipment?

Machines are usually packed in reinforced wooden crates or steel frames, with internal cushioning and moisture‑resistant liners to protect electronic components.

What are the common lead times for these testing machines?

Standard production lead times range from 30 to 60 days after receipt of a confirmed order and all required documentation.
