Porous Array Flow Distribution Plate

Designed for assembly requirements in vacuum adsorption, fluid diffusion, and precision filtration components, these rectangular plates achieve uniform media permeation or pressure balance through a high-density, regularly arranged matrix of micro-holes on the surface. Counterbored mounting holes at the four corners facilitate rigid docking with the base, ensuring positional stability when used as functional panels in automated equipment or semiconductor fixtures.

The core of the manufacturing process lies in ensuring dimensional consistency and hole wall smoothness across the dense hole array, preventing diameter deviations and burr residue caused by tool wear or thermal deformation. Due to the extremely small pitch of the holes penetrating the entire plate, high-rigidity CNC machining centers combined with micro-diameter tools are employed for multi-path milling or drilling. This is supplemented by strict deburring processes to ensure unobstructed flow channels and flatness of the assembly plane, thereby avoiding any negative impact on sealing effectiveness.

Shenzhen Chaozhuo Quick Technology Co., Ltd. is equipped with high-precision CNC machining centers from brands such as Zeguan and Jiafu, capable of processing various metal materials including stainless steel, aluminum, and copper alloys. For non-standard custom parts involving thousands of micro-hole features, we evaluate tool paths and clamping solutions based on customer-provided 2D/3D drawings. We offer one-stop solutions ranging from material selection to surface treatments like sandblasting and anodizing, meeting stringent delivery standards for porosity and appearance quality.
