In October 2025, Yantai Longda Materials will conduct research and development on materials such as coatings, porous carbon, organic silicon, epoxy, polyurethane adhesives, etc., and will require a resistance tester for breakdown testing. Therefore, they will purchase resistance breakdown equipment from our factory.

1、 Equipment capabilities related to Beiguang Precision Instrument

Voltage breakdown tester
Its BDJC series covers a voltage range of 10KV to 150KV, suitable for dielectric strength testing of materials such as films, rubber, ceramics, etc. It is equipped with PLC control modules and discharge systems, and meets insulation material testing standards.

Vertical resistance testing technology
Measuring the resistivity under dynamic pressure using the four terminal method, supporting the evaluation of the conductivity performance of new energy battery materials such as carbon paper and bipolar plates, with a pressure accuracy of ± 0.5%

Customization of intelligent detection equipment
Combining the BEST-380 resistivity tester from Beiguang Precision Instrument (supporting high-precision detection) with the accumulation of Longda materials in the synthesis process of organic silicon, optimize the production yield of organic silicon materials.

Laboratory co construction and standard output
Referring to the cooperation model between Beiguang Precision Instrument and Chinalco Shandong Group (providing resistance tester, dielectric constant tester, breakdown tester, leakage trace tester, tensile tester, and hardness tester), both parties can jointly establish a new material joint laboratory to promote the development of industry standards in the field of Longda material testing.

2、 Technical cooperation and R&D collaboration

Complementary abilities of industry, academia and research
Beiguang Precision Instrument has independent research and development capabilities (such as intelligent chemical frequency withstand voltage testing devices), and can provide overall laboratory solutions (including design planning, calibration services), which may assist Longda in optimizing material testing processes and laboratory management systems.
Both parties may explore testing methods for the dielectric properties of organic silicon to improve detection efficiency.

3、 Collaborative expansion of industrial chain

Market layout in the field of new energy
The application of Beiguang Jingyi equipment in the detection of thermal management materials for new energy batteries and the synergy with Longda materials in the fields of new energy vehicles and energy storage may promote deep cooperation between the two sides in the new energy industry chain.

Potential for industrial chain synergy

Deep binding in the field of new energy
Beiguang Jingyi provides testing equipment (such as voltage breakdown testers) for new energy vehicle companies such as BYD, while Longda materials are widely used in thermal management of new energy batteries. The two parties can jointly develop material testing solutions that are compatible with energy storage systems and fast charging technologies, seizing key links in the new energy industry chain.
