Company profile
Huangshan Juxin New Material Co., Ltd. is a national high-tech enterprise specializing in the R&D, production, and sales of high-performance polyimide resin, while providing integrated technical solutions and customized services. Its polyimide portfolio is organized into five series: basic, modified, functional, filled, and soluble types. The company positions these materials for bearings, gaskets, gears, seals, transmission components, insulation components, high- and low-temperature-resistant precision components, toughening agents, adhesives, and coatings, with application fields including aerospace, electronics and electrical equipment, semiconductors, automobiles, precision instruments, industrial robots, and plasma cutting. Huangshan Juxin New Material Co., Ltd. is also a Chinese manufacturer of PI plastic, PI material, polyimide resin, and PI engineering plastics, complementing its high-performance polyimide R&D, production, sales, integrated solutions, and customization capabilities.
Exhibits
Polyimide sheets are supplied in natural-material, graphite-modified, and antistatic variants, covering both graphite-modified polyimide sheet and antistatic polyimide sheet requirements. The product range also includes polyimide hot runner nozzles. Polyimide rods are described as resistant to high and low temperatures, wear, and chemical solvents, while also being easy to process and lightweight. A-PI-280 is presented as a corrosion-resistant polyimide rod for engineering-plastic applications. A-PI-330 is a chemical-resistant polyimide resin sheet identified for heat protection in the semiconductor industry. A-PI-350-A is listed as an insulating polyimide rod made from modified polyimide resin. JSM-PI polyimide is a high-performance special engineering plastic developed and produced by Huangshan Juxin New Material Co., Ltd., combining high-temperature stability, mechanical properties, electrical insulation, chemical stability, a low thermal-expansion coefficient, dimensional stability, low outgassing, and processing performance. The company also describes a one-meter polyimide rod at 1000 mm length that is machinable, wear-resistant, has good tensile strength, resists chemicals and lubricating oil, and is rated for -269℃~350℃. For hot runner molds, JSM-PI profiles are presented for use where high-temperature resistance, a low thermal-expansion coefficient, mechanical properties, and chemical stability are required. In hot runner insulation, polyimide profiles can be made into insulation gaskets and bushings that separate the high-temperature runner from lower-temperature mold sections, using low thermal conductivity and high-temperature resistance to reduce heat loss and improve system efficiency. Polyimide insulation sleeves can also be placed around hot runner nozzles to limit heat transfer to other mold parts and support temperature-control accuracy. For structural support at elevated temperature, the profiles can be used for hot runner plate support parts, where low thermal expansion and high mechanical strength help maintain plate stability. They can also be used for locating pins and guides that maintain dimensional stability while reducing friction and wear in high-temperature mold environments. For moving hot runner components such as valve needles, polyimide profiles are used for sliding bearings and bushings because of self-lubricating and wear-resistant behavior, with the stated purpose of extending mold service life. Valve-needle hot runner systems can use polyimide valve-needle guides to support smooth needle movement at high temperature while reducing wear. Where hot runner molds process corrosive plastics containing halogens or acidic components, polyimide profiles can be used for seals and corrosion-resistant parts because of their chemical stability. Polyimide profiles are also described as solvent-resistant parts for hot runner systems that require frequent cleaning with chemical solvents. Electrical-heating-element insulation parts can be made from the profiles where electrical insulation and high-temperature resistance are needed for safe heater operation. High-strength, low-density polyimide profiles are presented for lightweight mold structural parts to reduce mold weight and improve operating efficiency. The same profile family is used for high-strength connectors intended to maintain mold structural stability under high temperature and high pressure. Quick-mold-change systems can use high-temperature-resistant, low-friction polyimide parts to improve production efficiency, and sealing sections can use high-temperature sealing rings to maintain sealing performance at elevated temperature. JSM-PI hot runner use is based on high-temperature resistance, low thermal expansion, wear resistance, chemical stability, and electrical insulation, a combination intended to improve mold performance and service life. For automotive applications, polyimide profiles are described for engine-system gaskets, oil seals, and other sealing parts, where high-temperature, oil, and chemical-corrosion resistance are intended to help prevent leakage under demanding operating conditions. For aerospace structures, JSM-PI profiles are described for wing and fuselage components such as ribs, stringers, fuselage frames, and skin, with the purpose of reducing aircraft weight while retaining structural strength. Across its application pages, Huangshan Juxin connects JSM-PI profiles with semiconductor, plasma-cutting, hot-runner-mold, automotive, and aerospace uses, while its product pages emphasize a combination of heat resistance, dimensional stability, chemical resistance, electrical insulation, and machinability for engineered components. The one-meter polyimide rod is specifically promoted as a format intended to save processing costs, while retaining the listed 1000 mm length, machinability, wear resistance, tensile strength, chemical and lubricating-oil resistance, and -269℃~350℃ temperature capability. Polyimide profile applications in hot runner molds cover insulation components, structural-support parts for high-temperature environments, wear-resistant and low-friction parts, chemically resistant parts, high-temperature insulation parts, lightweight and high-strength parts, and special applications, giving each material property a defined mold function. Hot runner plates are identified as components that can expand thermally at elevated temperature, so low-thermal-expansion, high-mechanical-strength polyimide support parts are used to help keep the plate stable rather than transferring that dimensional change through the supporting structure. For locating and guiding functions, the material is used where the pin or guide must retain dimensional stability through high-temperature operation and at the same time reduce friction and wear at contact surfaces inside the mold. The wear-resistant application is tied specifically to moving parts in the hot runner system, including valve needles, where low friction is required; the stated self-lubricating and wear-resistant behavior is the reason given for using polyimide sliding bearings and bushings to extend mold life. Chemical-service applications cover two conditions: corrosive-plastic processing, where seals and corrosion-resistant parts may encounter halogen-containing or acidic materials, and cleaning service, where mold parts can be exposed repeatedly to a variety of chemical solvents. In the electrical-heating section of a hot runner system, the heating elements are described as requiring reliable insulation, and polyimide profiles are used for the insulation parts because they combine electrical insulation with high-temperature resistance for safe heater operation. As hot runner technology continues to develop, polyimide profiles have broader application prospects based on the same combination of high-temperature resistance, low thermal expansion, wear resistance, chemical stability, and electrical insulation.
