ZHD Hardware Cast Iron Table Base: 9-Core Production Process for Commercial Use

The requirements for durability and stability of cast iron table bases in commercial catering and other scenarios are far higher than those in household scenarios, which also forces furniture hardware enterprises to improve production standards. As a professional manufacturer with more than 19 years of experience, ZHD Hardware deeply understands the core needs of commercial scenarios and has built a standardized production process covering 9 core links, perfectly integrating the craftsmanship of traditional casting with the precision of modern technology. From the early demand-adaptive design to the later finished product packaging and protection, every step is strictly controlled. This is the core reason why ZHD Hardware's cast iron table bases can withstand high-frequency commercial use and maintain stable performance for a long time.

Details: The first step in the production process is design and mold making, which is the foundation of product quality. ZHD Hardware's engineering team constructs precise models through professional CAD software, fully considering the load-bearing requirements, weight distribution and aesthetic design of the table base, and simultaneously collaborating with customers to confirm demand details. After the model is determined, precise molds are made of wood or metal materials. The error control of the mold directly determines the integrity of the final product, so this link is manually calibrated by senior craftsmen throughout the process.

After mold preparation, the smelting and pouring link begins. ZHD Hardware uses a cupola furnace or induction furnace to melt high-quality cast iron alloy at high temperature, strictly controlling the carbon content to balance hardness and toughness and avoid brittleness. The pouring process is operated by experienced technicians to ensure that the molten iron is evenly injected into the sand mold (traditional green sand or resin sand material, adapting to different detail requirements), preventing defects such as air holes and incomplete filling.

After pouring, scientific cooling and shakeout cleaning are required. The cooling time is accurately adjusted according to the thickness of the table base to avoid internal stress caused by uneven cooling; after shakeout, residual sand and excess metal on the surface are removed by shot blasting, grinding and other methods, followed by fine trimming (fettling) to ensure a smooth and uniform surface. The subsequent heat treatment link further optimizes the material performance, improving toughness and eliminating stress through annealing process, making the table base more impact-resistant.

Surface treatment and quality inspection are the key to quality control. ZHD Hardware adopts environmentally friendly powder coating, painting and other processes, which not only improve corrosion resistance but also enrich appearance options; in the inspection link, dimensional measurement, load-bearing test, ultrasonic flaw detection and other methods are used to comprehensively check for dimensional deviations, hidden cracks and other problems. Finally, accessory assembly and customized packaging are completed according to customer requirements to ensure that the finished product is not damaged during transportation.

From design modeling to finished product packaging, ZHD Hardware's 9 production links form a complete quality control closed loop. The experience precipitation of traditional craftsmen and the precise empowerment of modern technology make each cast iron table base have both structural stability, aesthetic value and durability. Whether it is a high-frequency use restaurant scenario or a quality-pursuing residential space, ZHD Hardware's production process can ensure that product performance is always online, becoming a quality model in the furniture hardware field.
