Dongguan OJI Precision Hardware Co., Ltd. specializes in manufacturing high-precision hardware parts and components, such as water hose storage carts, stainless steel headphone headbands, and thin stainless steel tubes.

Through independent innovation, the company has developed water hose storage carts for greening and irrigation applications. These carts effectively solve common problems including hose tangling, knotting, damage, leakage, difficult dragging, and time- and labor-consuming storage. They significantly reduce auxiliary operation time and improve work efficiency.

In terms of equipment, the company is equipped with conventional machines including CNC machines, computer lathes, conventional lathes, milling machines, grinding machines, flattening machines, looping machines, punching machines, wire drawing machines, polishing machines, and sandblasting machines. In addition, the company has independently developed special equipment for headband processing, such as synchronous rolling machines and slotting machines. The dimensional precision of headbands is controlled within ±0.03 mm in width, ±0.01 mm in thickness, and ±0.3 mm in profile.
