A customer from Jiaxing, Zhejiang, visited Guangzhou Hengde to inspect the self‑insulating masonry blocks and the lightweight foamed concrete fire‑resistant door core panel projects.
On July 24, 2026, a customer from Jiaxing, Zhejiang, visited Guangzhou Hengde to inspect the production process for lightweight foamed concrete fire‑door core panels, the self‑insulating block production line, and the non‑destructive cutting technology for 2‑meter‑long door core panels. The visit included in-depth discussions on upgrading fire‑door core materials and on an overseas plant‑construction project.
On July 24, 2026, a delegation of customers from Jiaxing, Zhejiang, visited Guangzhou Hengde Building Technology Co., Ltd. for an in-depth discussion on the self‑insulating block production project and the direction of upgrading fire‑door core panel materials. During the visit, the clients gained a thorough understanding of Hengde’s lightweight wall‑material equipment, manufacturing processes, and product application areas. They also closely observed the cutting process for fire‑door core panels, expressing high praise for the non‑destructive cutting performance of Hengde’s 2‑meter‑long door cores and for the advanced technology behind its lightweight foamed concrete materials.
According to reports, the client’s visit focused on two key project areas: first, a plan to launch a self‑insulating block production project in Kazakhstan; and second, an upgrade and modernization of the local fire‑door coreboard manufacturing process in Jiaxing, Zhejiang. The client believes that, as market competition intensifies and product specifications become more stringent, traditional magnesium oxide‑based coreboards are undergoing significant market consolidation, prompting fire‑door manufacturers to seek new core materials and production processes that are more stable and better suited for large‑scale manufacturing.
Jiaxing, Zhejiang, is one of China’s major hubs for the fire door industry, home to a large concentration of manufacturers and supporting suppliers. According to customer feedback, many local fire door producers are now focusing on new core‑material technologies, seeking to enhance product quality stability and market competitiveness through advances in materials, processes, and equipment. Customers also acknowledge that conventional core‑board manufacturing has entered a critical phase of transformation; without timely adjustments, companies may face pressure to halt production, shut down, or be phased out by the market.
In response to the client’s requirements, the Guangzhou Hengde team, drawing on the client’s existing factory infrastructure, product strategy, market positioning, and future investment plans, conducted detailed discussions on both the Kazakhstan self‑insulating block project and the local fire‑door core board upgrade project. For the Kazakhstan project, the Hengde team highlighted the production line’s process flow, equipment configuration, raw material compatibility, capacity planning, and post‑installation support, providing valuable guidance for the client’s subsequent overseas plant‑construction efforts.
Regarding the direction of upgrading fire‑door core panels, both parties engaged in an in-depth discussion centered on the application of lightweight foamed concrete in panel production. Compared with conventional material solutions, the lightweight foamed concrete core‑panel project places greater emphasis on material lightness, product stability, production continuity, and compatibility with downstream processing. The customer expressed strong interest in Hengde’s technical roadmap for lightweight foamed concrete processing, equipment integration, and core‑panel fabrication.
During this visit, the customer focused on observing a demonstration of 2-meter-long fire‑door core panel cutting. Given the considerable length of these panels, the cutting equipment is required to deliver exceptional stability, precise cut flatness, and impeccable finished‑product integrity. Any defects—such as chipping, corner loss, edge breakage, or dimensional deviations—during the cutting process would directly compromise the subsequent panel lamination and the overall quality of the finished product. By inspecting the equipment in operation, evaluating the cutting methodology, and reviewing the resulting finished parts, the customer gained a more intuitive understanding of Hengde’s non‑destructive cutting technology.
The customer stated that upgrading the core material of fire doors is no longer a simple matter of substituting one raw material; it entails a comprehensive adjustment to the entire door manufacturer’s subsequent production model and market competitiveness. This visit to Guangzhou Hengde has given the customer a more systematic understanding of the production process for lightweight foamed‑concrete fire‑door core panels, the manufacturing scheme for self‑insulating masonry blocks, and the associated cutting equipment, further strengthening the customer’s confidence in Guangzhou Hengde’s technological expertise and equipment solutions.
For fire‑door manufacturers in Jiaxing, Zhejiang, upgrading the core‑board materials of fire doors is not merely a matter of product transformation; it also represents a critical strategic direction for identifying new growth opportunities amid industry consolidation. This customer visit underscores the door‑industry’s keen interest in innovative, lightweight fire‑door core materials and automated production processes, while laying a solid foundation for deeper collaboration between the two parties on self‑insulating masonry block projects and the modernization of fire‑door core‑board production lines.
