External supplier listings additionally identify the firm as operating from Chengde High-tech Zone and as a manufacturer of plastic material and pipe testing machines.
History and Development
Jinjian’s corporate history, as presented in company materials, begins in 1994, when the firm was established in Chengde. Over the following years, it expanded from a relatively narrow product base into a more diversified tester manufacturer serving plastic profiles, pipes, engineering plastics, and other polymer applications.
A second milestone in the company’s development was the adoption of enterprise digital management systems, including ERP, which the company says it introduced in the mid-2000s to improve coordination across production, supply, sales, and after-sales service. Later company descriptions indicate additional internal systems such as MES, KPI, SOP, KBS, and PLM, reflecting a move toward more structured manufacturing execution and product life-cycle management.
A third milestone is the company’s positioning as a specialized and innovative small- and medium-sized enterprise. The Chinaplasonline exhibitor listing identifies the company as a “specialized, refined, distinctive, and innovative” enterprise under Chinese government recognition. Other materials describe it as a national chemical building materials testing instrument technology demonstration industrialization base cultivated by the Ministry of Construction, underscoring its role in a niche industrial segment rather than in mass-market machinery.
Business Operations and Segments
Jinjian’s core business is the research, manufacture, and sale of testing instruments for polymer materials and related products. Its commercial focus is concentrated in the following broad areas:
- Plastic pipe testing
- Engineering plastics testing
- General mechanical property testing
- Thermal deformation and softening point testing
- Impact and stiffness testing
- Melt flow and rheological testing
The company’s production and sales materials indicate that it serves both domestic and international customers, with contact information and English-language pages supporting export-oriented business development. Third-party supplier databases also classify it as a manufacturer and trading company, suggesting a business model that combines direct factory production with export or distribution channels.
Products and Technologies
Jinjian’s product line centers on materials testing machines for the plastics sector and adjacent industries. The company’s published materials repeatedly mention the following equipment categories:
- Hydrostatic Pressure Tester for plastic pipes and pressure-performance evaluation
- Ring Stiffness Tester for pipe rigidity and deformation behavior
- Falling Weight Impact Tester for impact resistance of pipes and plastic products
- Universal Testing Machine for tensile, compression, and other mechanical tests
