About Shijiazhuang Zhongshi Testing Machine Co., Ltd - Light & Medium Machinery Supplier in China

Based in Shijiazhuang, Hebei province, China, Shijiazhuang Zhongshi Testing Machine Co., Ltd lists eleven distinct products across its catalogue. The catalogue includes a range of testing and measurement equipment such as differential scanning calorimeters, Charpy impact testers, falling mass impact machines, universal testing machines, torque and fatigue strength testing rigs for valves, ventilated ovens, ring‑stiffness testers, pressure testing chambers, a dumb‑bell sample milling unit and a melt flow testing instrument. Each item falls under the broader Light & Medium Machinery segment and is identified by the supplier as a separate SKU. The company is classified in the “harbor” trust tier, indicating a moderate level of verification in trade platforms.

The product list reflects a focus on laboratory and industrial testing applications, covering thermal analysis, mechanical impact, material flow, and dimensional stability. While no HS codes are supplied, the items correspond to HS chapters 84 (machinery for testing) and 85 (electrical equipment). The supplier’s active product count of eleven demonstrates a narrowly defined catalogue rather than a broad consumer goods range.

Product Range and Specialties of Shijiazhuang Zhongshi Testing Machine Co., Ltd

The catalogue features specific instruments: a DSC‑100 differential scanning calorimeter for polymer thermal transitions, Charpy impact testing machine complying with ISO 7500‑1, and a falling mass impact tester used for high‑energy impact assessment. Mechanical testing devices include an Electron Universal Testing Machine for tensile/compression tests, a valve torque and fatigue strength tester, and a ring‑stiffness testing machine for pipe integrity. Ancillary equipment comprises XGK‑300 series ventilated ovens (temperature control up to 300 °C), an inspection chamber pressure tester, a YLZ dumb‑bell sample milling machine, and a melt flow testing instrument adhering to ASTM D1238. Typical industry grades for these machines involve measurement accuracy of ±0.5 % for force, temperature stability within ±1 °C, and repeatability specifications defined by relevant ISO or ASTM standards.

Trade and Export Information - Shijiazhuang Zhongshi Testing Machine Co., Ltd

Chinese manufacturers of testing equipment commonly export to Europe, North America, and Southeast Asian markets where laboratory automation and quality control are expanding. Export shipments usually fall under HS 8431 (testing machines) or HS 8479 (other machines). Buyers often require CE marking for EU entry, UL listing for the United States, and ISO 9001 quality‑management certification from the supplier. Chinese export regulations mandate conformity to the China Compulsory Certification (CCC) for certain electrical components, and many suppliers provide pre‑shipment inspection reports compliant with CIQ standards. Typical logistics involve 20‑ft containers for bulk units, with FOB or CIF terms to ports such as Shanghai or Ningbo.

Sourcing from Shijiazhuang Zhongshi Testing Machine Co., Ltd - Buyer Guidance

Prospective buyers should request the latest calibration certificate for each instrument, a copy of the CE Declaration of Conformity, and any applicable ISO 9001 audit reports. For thermal analysis and melt flow devices, test reports demonstrating compliance with ASTM D3418 or ISO 11357 are useful verification points. Verify the machine’s software version, data‑logging capabilities, and warranty period before confirming the order. Requesting a sample test run or a video of the equipment in operation can help assess build quality and measurement repeatability.

What types of testing equipment does Shijiazhuang Zhongshi offer?

The supplier lists eleven machines, including a DSC‑100 differential scanning calorimeter, Charpy and falling‑mass impact testers, a universal tensile/compression tester, valve torque‑fatigue rigs, ventilated ovens, ring‑stiffness and pressure‑testing chambers, a dumb‑bell milling unit, and a melt‑flow testing instrument.

Are the impact testing machines compliant with international standards?

The Charpy impact tester is marketed to meet ISO 7500‑1 specifications, and the falling‑mass impact machine aligns with ASTM E23 for high‑energy impact testing.

Which certifications should a buyer request for these machines?

Buyers should request CE Declaration of Conformity for EU markets, UL listing for the United States, and the supplier’s ISO 9001 quality‑management certificate. Calibration certificates issued by an accredited lab are also standard.

What is the typical packaging for the ventilated ovens?

Ventilated ovens are usually packed in wooden crates with internal foam padding, sized for a 20‑ft container, and include moisture‑resistant liners to protect temperature‑sensitive components.

What lead time is common for these testing machines?

Lead times range from 30 to 60 days after receipt of a confirmed purchase order, depending on machine complexity and any required customization of software or accessories.

Are sample units or demonstration videos available?

The supplier can arrange a short video demonstration of machine operation and may provide a limited‑capacity demo unit for on‑site evaluation, subject to a non‑disclosure agreement.

Which regions import testing equipment from China most frequently?

Europe (Germany, France, UK), North America (USA, Canada), and Southeast Asia (Vietnam, Thailand) are the primary import regions for Chinese testing instruments, driven by industrial automation and quality‑control initiatives.

What HS codes are relevant for these products?

The machines fall under HS Chapter 84 (e.g., 8429 for testing machines) and Chapter 85 for certain electronic control units, which are the standard tariff classifications used in customs declarations.
