Telecommunication Equipment Enclosure Fabrication Aluminum Processing × High-Precision Press-Fit × Black Textured Coating We manufacture enclosure components for telecommunication equipment used in server racks and data centers. From aluminum fabrication and high-precision nut insertion to black textured coating, we provide consistently high quality and stable supply for technically demanding processes. Overview LEO ELECTRONICS (VIETNAM) is a Japanese-owned EMS manufacturer based in Vietnam, specializing in the fabrication of enclosure parts and structural components for data center and telecommunication infrastructure equipment. We respond accurately to design intent while ensuring stable quality and mass-production readiness. By managing multiple processes in-house—including high-precision cutting using combination machines, nut press-fit insertion, welding, coating, and Alodine surface treatment—we deliver products that meet the strict quality standards required for telecommunication equipment. In the nut insertion (press-fit) process, we optimize pressing force, insertion speed, and holding time, achieving stable retention even for parts that previously faced drop-off risks with other suppliers. In addition, for structures where products are stacked or overlapped, uniform coating thickness of black textured coating is critical. Our coating quality control know-how is a key strength in ensuring defect-free performance. Key Features High-precision cutting using combination machines (fiber laser + punch), capable of processing large aluminum enclosures Optimized nut press-fit control, preventing detachment and ensuring high and stable holding strength Coating quality management, achieving uniform film thickness in black textured coating with no issues during stacked use Welding capability for aluminum enclosures, using an AMADA spot welding machine (ID404HPNT) for stable and repeatable quality Support for Alodine treatment and black/white anodizing, with proven experience for U.S.-spec speaker products Strong cutting capability for large aluminum enclosures used in telecommunication equipment Specifications Processing size: Approx. W500 × D650 × H200 mm (medium-size telecommunication equipment) Materials: Aluminum (A5052), steel (SECC, SPCC), stainless steel (SUS304, etc.) Processes: Fiber laser cutting, punching, press-fit insertion, aluminum welding, spot welding, coating, Alodine treatment Production equipment: Combination processing machines, spot welding machines, coating facilities, deburring machines, angle-controlled bending machines, etc. Applications Server rack enclosure components for data centers Enclosures and structural frames for telecommunication equipment Speaker frames and boxes for railway applications Enclosure units for network equipment and control devices Industries Served Telecommunication infrastructure equipment manufacturers Data center equipment manufacturers Railway vehicle and transportation infrastructure manufacturers (especially for the U.S. market) Trading companies and design firms engaged in OEM / ODM design and mass production of telecommunication equipment With strong capabilities in cutting, press-fit insertion, coating, and welding, we contribute to stable product supply and consistent quality in the telecommunication equipment field. ■ Please download the PDF for more details or feel free to contact us for inquiries.

The parking rod is a safety-critical component responsible for holding an automatic transmission (AT) vehicle in a stationary condition. As a safety part, its heat treatment conditions and cam angle accuracy are strictly specified. These requirements are essential to ensure that the vehicle remains securely stopped in the P range and does not move due to malfunction or misoperation. ■ Safety Requirements for the Rod The rod undergoes high-frequency induction hardening followed by tempering. During this process, precise control of surface hardness and case depth is required. In addition, the hardening pattern must never penetrate into non-designated areas. If the hardness is too low, wear progresses rapidly and the locking function may be lost. If the hardness is too high, the risk of brittle fracture increases. Proper management of the localized heat treatment pattern, which hardens only the specified areas, is the key to maintaining safety performance. ■ Safety Requirements for the Cam The cam requires a higher hardness than the rod, achieved through carburizing heat treatment, as it functions as a sliding contact surface repeatedly engaging with the rod and therefore demands high wear resistance. The case depth is strictly specified, and the cam angle is managed as a critical safety characteristic. Even a slight deviation in cam angle can alter engagement with the parking pawl, potentially causing a situation where the vehicle does not fully stop despite being in the P range. ■ Risks When Safety Characteristics Are Not Maintained Abnormal wear Part fracture Deformation due to improper heat treatment Cam angle deviation If any of these occur, the vehicle may begin to move even when the transmission is in the P range, directly leading to serious accidents and personal injury. ■ Manufacturing Control to Ensure Safety Performance To protect safety performance, the following controls are essential: Process assurance of heat treatment conditions (temperature, case depth, hardness) Visual inspection and hardness testing to verify hardening patterns High-precision cam angle measurement and lot variation control Measurement of deformation after heat treatment (straightness, dimensional changes) In-process checks for abnormal wear These activities are not merely quality control measures, but safety management practices aimed at accident prevention. ■ Strengths of Ohashi Tekko Vietnam At Ohashi Tekko Vietnam, heat treatment of rods and cams, as well as cam angle control, are managed as special safety characteristics in accordance with standards established by the Japanese headquarters. Through precise measurement of hardness, case depth, and cam angle, along with comprehensive evaluation of post–heat treatment deformation, the company ensures stable supply of high-reliability parking rods and related components that support vehicle safety.
