Recently, our company has achieved a key technical breakthrough in the manufacturing of micro-hole perforated sheets. We have realized stable mass production of precision perforated sheets with 1.0mm plate thickness and 0.7mm hole diameter. This breakthrough breaks the conventional processing limit where the plate thickness is normally smaller than the hole size. We now successfully deliver perforated sheets where the plate thickness exceeds the hole diameter, expanding our lineup of precision perforated metal products to meet diversified demands from global customers across various industries.
In traditional perforating processes, punching holes smaller than the sheet thickness is widely recognized as a tough technical challenge. It often leads to frequent punch pin breakage, distorted holes, excessive burrs and sheet warping. This demanding work requires ultra-precise dies, stable punching equipment, optimized punching speed and strict raw material control.
After repeated die adjustments, process parameter tests and sample inspections, our R&D and production team refined the stamping solution and strictly controlled every production step to overcome this technical barrier. The finished sheets feature uniform and neat holes, consistent pitch, a flat surface and qualified burr control with stable and reliable quality.
Compared with conventional thin-gauge micro-hole perforated sheets, this new 1.0mm T / 0.7mm hole product boasts greatly improved wear resistance. The thicker substrate maintains the functions of fine screening, filtration, ventilation and noise reduction, while offering stronger impact resistance, anti-abrasion performance and deformation resistance for a longer service life.
It is widely applicable for precision screening, filtration & purification, noise control, machinery guard panels, new energy supporting parts, grain & chemical separation, precision instrument protection and more. It perfectly solves customers’ pain point of needing both tiny holes and excellent wear resistance.
The whole production and delivery workflow — from coil feeding & punching, cutting to size, quality inspection, packaging, palletizing and container loading — is fully established. This specification is now available for bulk orders with consistent supply. We support customization in stainless steel, galvanized steel and other materials, as well as custom sheet sizes, hole patterns and surface finishes.
This milestone is a result of our continuous focus on precision perforated metal and advanced fabrication capability. Moving forward, we will keep developing advanced processing technologies for ultra-fine holes and thick-plate perforation. We are committed to delivering reliable quality and one-stop custom perforated metal solutions for customers worldwide.
