HDPE Bar can be categorized into Hollow Bars and Solid Bars, each with its own specific applications and advantages.
Solid bars have certain advantages in terms of pressure and bending resistance due to their solid structure, which provides higher rigidity and stability and is suitable for processing environments with high loads. Solid bars are particularly suitable for applications requiring high-precision machining and can provide more reliable performance in situations where greater pressure or heavy loads are required. Additionally, when solid bars are heat-treated for hardness and wear resistance, the treatment effect is relatively uniform, improving durability during machining.

Hollow rods, on the other hand, are slightly less strong because of their internal voids, but they can meet the requirements of most working conditions through the use of high-strength materials and optimized design. The heat treatment of hollow bars may be affected by uneven heat distribution due to their internal cavities, but it is more cost-effective because the amount of material used is less and relatively more economical. It is also relatively inexpensive to transport and install due to its low weight. Hollow rods are more suitable for standard or light-duty processing environments, especially where there are limitations on the weight of the equipment, where their lightweight properties can be of great advantage.
