Makers are devoting a larger portion of their expenditure to automated equipment. Facilities are also being upgraded. Amid stiff competition and pricing pressure, anchor bolt suppliers in China are bolstering manufacturing capability to ensure product specifications meet international standards. The majority of companies are investing substantially in high-tech, automated equipment. This includes high-precision lathes and centerless grinding, thread-rolling, tapping and drilling machines sourced from Germany, the US, Japan and large domestic suppliers. Besides precise dimensions, these computer-controlled devices help yield models with acceptable tensile strength, tension and shear load levels, properties critical to performance and safety. The use of 3-D designing software helps makers achieve accurate structure and measurement. Although new machines are being acquired, suppliers are also improving existing technologies. Tai He Yu Precision Metals Co. Ltd has allotted about $2.5 million to the upgrading of current facilities, particularly those for lathing, punching, milling, drilling and cutting. This enables the supplier to offer a range of product options. Anchor bolts from Tai He Yu come in diameters of 0.5 to 40mm and lengths between 0.5 and 120mm. Enhanced production at Shanghai Uni-star Industrial & Trading Co. Ltd is resulting in vibration-resistant designs with high gripping power, making them suitable for heavy-duty applications. The company also emphasizes quality. Its 20-member QC team tests materials and components before volume production is initiated. Dezhou Hualude Hardware Products Co. Ltd performs testing and inspection in accordance with the ISO 9001:2000 standard.
