Xingjia Company: Over a Decade of Dedication to High-Performance Heat Shrink Tubing and Silicone Tubing, Achieving Excellence

2026-02-22

In the high-stakes industries of rail transit, new energy vehicles, and military equipment, the reliability of insulation and protective materials is paramount. Dongguan Xingjia Electronics Technology Co., Ltd. (hereinafter referred to as Xingjia) has been a steadfast leader in this domain since its inception in 2016. Over the past decade, the company has dedicated itself to the research, development, and production of high-performance shrink tubes and silicone tubes, establishing itself as a benchmark in the industry through relentless innovation and unwavering commitment to quality.

‌Technical Mastery: Redefining Material Standards

Xingjia’s core product portfolio includes silicone heat shrink tubes, oil-resistant rubber heat shrink tubes, and anti-slip patterned heat shrink sleeves. These products are engineered to meet the rigorous demands of high-voltage insulation, battery pack protection, and extreme environmental conditions in sectors such as rail transit and military applications.
The company’s adherence to international quality standards is evident in its ISO 9001 certification and proprietary testing laboratory, which ensure compliance with FDA and RoHS regulations. Technologically, Xingjia has pioneered advancements such as multi-layer co-extrusion technology, which enhances the uniformity of tube wall thickness, and dynamic vulcanization processes, which significantly improve oil resistance in silicone tubes.
A standout achievement in 2025 was the development of a high-flame-retardant silicone heat shrink tube that obtained UL certification. This breakthrough product boasts an oxygen index of 35%, surpassing industry averages and providing enhanced safety for critical applications in rail transit.

‌Market Leadership: Beyond Products to Solutions

Xingjia’s success is not solely rooted in product excellence but also in its innovative "deep service" model. A notable example is the company’s involvement in the Shenzhen Metro Line 14 project. Here, Xingjia’s technical team proactively engaged in the design phase, optimizing the shrink ratio of the protective sleeves to address connector compatibility challenges. This collaborative approach enabled a rapid 48-hour emergency response, ensuring seamless project delivery and reinforcing the company’s reputation for reliability.

Over the past ten years, Xingjia has evolved from a startup into an industry leader with 15 patents and an annual production capacity of 80 million meters. Its products have been deployed in high-profile applications such as the CR400AF high-speed EMU trains, where they have demonstrated zero failure over three years of operation.

‌Future Vision: Pioneering New Frontiers

Looking ahead, Xingjia is poised to expand its focus into emerging sectors like 5G communication equipment and new energy battery protection. The company’s founder emphasizes a commitment to setting even higher industry standards: "Over the next decade, we will continue to push boundaries, delivering innovative solutions that redefine reliability and performance for global clients."
