Xuchang Chengrui Insulation Materials Co., Ltd.

Siti Rahmat, founder of TechGuard Insulation Solutions in Kuala Lumpur, had spent six years building her company into a trusted supplier of electrical insulation materials across Malaysia. Specializing in polyester films for transformers, motors, and solar panels, her business thrived on delivering high-quality products to industrial clients.

However, by early 2023, Siti faced mounting challenges that threatened her hard-earned reputation. Her previous supplier in China, which she had relied on for three years, began delivering inconsistent film thickness and delayed shipments. This led to frustrated customers, strained cash flow and excess inventory of substandard materials. Determined to resolve these issues, Siti revisited her procurement strategy. While local Malaysian manufacturers offered shorter lead times, their prices were 25–30%, higher, squeezing her margins. European alternatives provided technical excellence but at prohibitive costs. Turning back to China’s industrial hubs made economic sense, but she needed a supplier that combined precision, affordability and accountability. After weeks of researching websites and cross-referencing supplier reviews, Chengrui, a Henan-based polyester film manufacturer, stood out.

What caught Siti’s attention were Chengrui’s certifications—UL recognition and IEC compliance—which aligned with her clients’ stringent requirements. A video call with Chengrui’s export team addressed her concerns: their automated production lines ensured thickness consistency, a critical factor for insulation performance. Pricing transparency further impressed her; Chengrui’s quotes were 15%, lower than her former supplier’s rates, with FOB terms that simplified logistics. To verify quality claims, Siti requested sample rolls for tensile strength and thermal resistance tests. The results matched European benchmarks, convincing her to place a trial order for test.

The partnership’s success became evident within months. Chengrui’s Just-In-Time production model reduced TechGuard’s inventory costs by 18%, while the elimination of defective batches minimized waste. Most importantly, Siti’s clients reported fewer product rejections, strengthening their loyalty. By Q3 2024, TechGuard expanded its offerings to include Chengrui’s flame-retardant polyester films, tapping into Malaysia’s booming EV sector.

For Siti, Chengrui represented more than a cost-saving vendor—it became a strategic ally. “Their engineers helped us customize film coatings for high-humidity environments, which 40%, of our clients operate in,” she noted. “That’s the support we needed to lead in this niche.” Today, TechGuard supplies over 200 industrial facilities nationwide, with Chengrui films constituting 70%, of its insulation material inventory.

 This collaboration underscores how Malaysian SMEs can leverage China’s manufacturing expertise without compromising on reliability. For Chengrui, it reaffirms a commitment to empowering global partners through technical excellence and adaptive solutions on polyester film.
