About Our Company

Kunshan Guanghouhong Mold Materials Co., Ltd. was established in December 2014. Formerly known as Kunshan Guanghouhong Steel Co., Ltd., the company changed its name and adjusted its business scope in March 2025 to focus on the R&D, processing, and sales of mold materials. It is currently recognized as a national-level "SME based on science and technology" and an "innovative SME," holding an "A" rating for tax creditworthiness as of 2025.

The company holds a total of 18 utility model patents related to mold steel and 8 industrial software copyrights. Its core business centers on specialized mold steels—featuring high-temperature, wear, and corrosion resistance—complemented by precision plate processing, surface finishing, and heat treatment services. While primarily serving mold manufacturing enterprises in the Yangtze River Delta, the company also engages in the export of mold steel. In May 2026, the factory relocated to Building 4, No. 882 Jujin Road, Zhangpu Town, Kunshan City, where production capabilities were simultaneously upgraded.

Voices From Our Customers

Trust‑worthy mold material solutions recognized by worldwide industrial partners

Lucas, Manager

We’ve been sourcing special mold steels from this supplier for our new‑energy battery casing projects. Their high‑temperature die steel performs far better than our former supplies under continuous die‑casting cycles. Samples arrived fast, technical support responded timely whenever we met material matching issues. The complete inspection reports help us simplify our incoming quality check workflows. We are satisfied with their stable batch consistency and on‑time shipments, and will keep long‑term cooperation for upcoming production orders.

Isabella, Production Manager

Our medical consumable injection molding workshop needed corrosion‑resistant plastic mold materials. Their customized mold steel perfectly fits our strict hygiene‑related production requirements. The pre‑sales team gave professional material selection advice according to our actual working scenarios. Finished plates came with precise dimension tolerances, greatly lowering our subsequent processing workload. Every batch carries full test documentation, and after‑sales staff give quick replies for any technical questions. It is truly a reliable partner for our precision manufacturing business. 2.

Wilson, Technical Manager

We adopted their cold‑work mold steel for hardware stamping connector dies. The outstanding wear‑resistance extends our die service life obviously and cuts our mold replacement cost. Their intelligent processing capacity guarantees steady product quality across large‑volume orders. Whenever we adjust technical specifications, their team gives feasible suggestions actively. Complete quality certificates and flexible delivery schedules bring much convenience to our mass‑production plans. We highly recommend their mold material products to peers in the stamping industry.

Leo, Plant Manager

Our 5G communication component manufacturing business demands strict material performance standards. This supplier’s self‑developed mold steels meet all our core technical indicators. From drawing review to finished goods handover, the whole cooperation process goes smoothly. Their full‑cycle service covers material testing, processing and follow‑up technical guidance. Product stability reduces our production failure rate effectively. We have expanded our purchase volume this year and expect deeper collaboration in future material optimization projects.

Sophia, Procurement Manager

We source mold materials for home‑appliance die‑casting production lines. Their heat‑treated mold plates show stable performance under long‑time high‑temperature working conditions. The team offers thoughtful pre‑sales consultation and arranges sample testing efficiently. All delivered goods pass our incoming inspection without major problems. When minor application doubts appeared, technical personnel gave 24‑hour targeted guidance. Cost‑effective products together with considerate service make them our preferred mold‑material supplier.
