Fengrun Hardware: Sheet Metal Fabricator for CPO Switches & Computing Hardware

Mass Production Surge of CPO Switches: The Boom in Computing Equipment Drives Sheet Metal Machining Toward Higher Precision

Driven by the continuous expansion of AI computing power, bandwidth demands within intelligent computing centers keep rising. Co-packaged Optics (CPO) technology is being rapidly commercialized, and 1.6T and 51.2T CPO switches have transitioned from prototype testing to mass production. Orders for downstream equipment are booming, ushering in a shipment peak across the industrial chain. Meanwhile, new-generation optical communication switches pursue far more than production volume. Standards for overall machine structure, thermal design and electromagnetic shielding have been comprehensively upgraded. As the core structural carrier, sheet metal components face unprecedented stringent precision requirements. Traditional extensive sheet metal processing methods can no longer meet the demands of next-generation computing hardware.

Unlike conventional network equipment, CPO switches integrate switching chips, silicon photonic engines and high-density optical interconnection components. Internal electronic parts are arranged extremely compactly with space utilization pushed nearly to the limit. Tiny dimensional deviations may trigger assembly interference, fiber misalignment and insufficient thermal contact. High-speed optoelectronic signals are highly sensitive to assembly gaps. Poor control of clearances on sheet metal enclosures directly impairs electromagnetic shielding performance, resulting in signal interference and transmission errors. Coupled with thermal expansion generated during long-duration operation of high-power devices, the industry has set rigorous specifications for sheet metal products. Tolerance requirements for hole position accuracy, bending angles, flatness and welding deformation are drastically tightened, with tolerance standards advancing from the millimeter level to the micrometer level. Thin-walled structures, dense ventilation holes, integrated cavities and multi-layer mounting brackets have become mainstream structural forms.

Shifting market demands are reshaping the upstream sheet metal supporting supply chain. Precision sheet metal manufacturers capable of stable high-precision mass production and complete process control will become preferred partners for communication equipment suppliers.

In recent years, Fengrun Hardware Factory has deeply engaged in precision sheet metal manufacturing for communication and computing equipment, continuously optimizing comprehensive precision sheet metal processing technologies to seize opportunities brought by industrial upgrading.

Fengrun Hardware is equipped with a full set of high-power fiber laser cutting machines, CNC precision bending equipment and automatic laser welding production lines, alongside standardized precision processing workshops. Mature process solutions have been developed for sheet metal components used in computing hardware. For CPO switch enclosures, internal support brackets, shielding cavities and thermal sheet metal assemblies, the factory effectively controls bending deformation, minimizes burrs, and consistently guarantees hole coaxiality, flatness and assembly tolerances. A complete quality control system covers incoming material inspection, first article verification, in-process patrol inspection and full-dimensional finished product testing, supported by coordinate measuring machines (CMM). This ensures consistent product precision even for bulk orders and effectively addresses yield fluctuations that equipment manufacturers encounter during large-scale deliveries.

To cater to diversified customized requirements of communication equipment, Fengrun Hardware provides one-stop services including rapid drawing evaluation, small-batch prototyping and mass production. The factory is proficient in surface treatment processes for switch sheet metal such as anodizing, conductive coating, dust-proof and wear-resistant finishing, fully satisfying requirements of optical communication equipment for EMI shielding, long-term heat dissipation and reliable industrial operation. Many optical communication OEMs have established long-term in-depth cooperation with Fengrun Hardware after upgrading to CPO equipment, relying on stable precision sheet metal delivery to guarantee the mass production schedule of new hardware.

Looking at long-term industrial trends, the commercialization of CPO has only just begun. Shipments of high-speed switches, optical communication racks and computing servers will maintain growth over the next three to five years, widening the market gap for high-precision sheet metal. A clear dividing line has emerged in the sheet metal processing sector. Low-end processing models that merely compete on price and output are gradually phased out, while "precision, yield rate and delivery stability" have become core competitive advantages.

Competition in computing infrastructure extends to every component manufacturer in the upstream supply chain. As a precision sheet metal manufacturer, Fengrun Hardware continuously refines processing techniques and upgrades production lines.
