Company profile
JIANN SHENG MACHINERY & ELECTRIC INDUSTRIAL CO., LTD. was established in 1982 and is a global distributor and manufacturer of Electric Discharge Machines. Its product scope includes Wire Cut EDM, CNC EDM, ZNC EDM, Die Sinker EDM, and Diamond Wire Saw solutions, with multiple machine specifications and customized machines for different industry needs. Its machines are described as certified by CE, UL, and ISO, and company milestones include CE certification for CNC EDM series machines in 1996, ISO-9002 in 1997, CE certification for wire-cut machines in 1999, and ISO-9001 in 2003. JSEDM develops its own control systems for stable performance and user-friendly operation, using initial design, component selection, pre-production trials, and continuous optimization based on customer feedback to target efficiency, reliability, and low maintenance costs. Every machine goes through strict testing and validation throughout production, including incoming inspection, mechanical assembly, electrical assembly, machine testing, and final inspection before shipment. The company states that more than 3000 machines are installed worldwide and that it provides worldwide service, global technical services, and customized EDM solutions. Its precision-manufacturing approach combines high-quality components and precision assembly, and its engineering team advances control systems, EDM technology, and automation solutions to improve precision, productivity, and performance. The company describes EDM machines for automotive, aerospace, medical-device, and precision-engineering industries and says its production processes incorporate energy-efficient designs and environmentally friendly practices. In addition to machine sales and service, JSEDM provides production-process advice intended to match machines to customer production solutions. Company milestones include development of Orbit Loran Function for EDM with CNS Patent No.36630 in 1985, a new factory in Taichung Industrial Park in 1987, a Taiwan Quality Award for Orbit Loran Function Development in 1989, CNC wire-cut machine development in 1991, a submerged wire-cut machine in 2001, a new CNC system for EDM in 2002, an AWT Automatic Wire Threading system in 2006, and a Windows-based operating system for JSEDM wire-cut machines in 2008. The company also states that it was the first company in Taiwan to use DC Servo Drives in EDM in 1983 and the first in Taiwan to adopt AC-generator electroless cutting in 1999. Later milestones include development of various customized machines in 2014 and completion in 2024 of the latest CE model of wire-cut machine with a customer order. JSEDM also describes SiC processing and inspection collaboration in Arizona, advanced optical-industry activity at SPIE Photonics West 2026, Diamond Wire Saw showcases and a first launch with industry applications at SEMICON Taiwan 2025, more machine choices and customized machine modification at TIMTOS 2025, customized production solutions at TIMTOS 2023, and professional explanation and services at IMTS Chicago 2022. Additional milestones include overseas EDM market promotion in 1984, an internal organization divided into Production, Quality Control, Research and Development, Marketing and Sales, and Administration in 1988, and successful market promotion of JSEDM CNC machines in 1994. JSEDM states five design and management principles: Ease of Operation, Affordability, Quick Maintenance, High Precision, and High Cutting Efficiency, together with fast after-sales service intended to minimize customer waiting time. In its five-stage quality process, incoming inspection checks component material and specifications, precision mechanical assembly targets rigidity and stability, electrical assembly targets stable signal transmission and control performance, machine testing verifies accuracy and operational stability, and final inspection verifies quality and function before shipment.
Exhibits
Wire Electrical Discharge Machining removes material through electrical discharges between a wire electrode and the workpiece, and JSEDM classifies Wire EDM into High-Speed, Medium-Speed, and Low-Speed types based on wire movement and cutting speed. High-Speed Wire EDM uses molybdenum or tungsten wire in high-speed reciprocating motion at approximately 8 to 10 m/s, offering high cutting speed and relatively low machine cost for general machining and rough cutting. Because wire reversal can create vibration and instability, its typical accuracy is listed as ±0.02 to ±0.05 mm with surface roughness of approximately Ra 6.3 μm, and it is generally used for lower-precision requirements. Medium-Speed Wire EDM uses optimized wire speed and multiple cutting passes to improve machining quality; with wire speed of approximately 1 to 12 m/s, its accuracy and surface finish are described as between High-Speed and Low-Speed systems for medium-precision applications. Low-Speed Wire EDM uses brass or zinc-coated wire with continuous one-directional movement, typically below 0.2 m/s, to provide stable machining with minimal vibration and improved precision and surface finish. Low-Speed Wire EDM is listed with machining accuracy up to ±0.002 mm and surface roughness from Ra 0.2 to 0.8 μm, with multi-cut finishing used to further improve surface quality and dimensional accuracy. Its listed Low-Speed Wire EDM applications include precision mold manufacturing, aerospace components, semiconductor materials processing, medical components, and high-precision electronic parts. The company distinguishes High-Speed and Medium-Speed systems using reusable reciprocating molybdenum wire from Low-Speed systems using disposable brass wire with continuous one-directional movement, and describes Low-Speed Wire EDM as providing stronger linear accuracy, roundness, surface finish, and fine-detail capability. For high-precision components, precision molds, superior surface finish, and complex geometries or fine features, the company recommends Low-Speed Wire EDM, while it describes High-Speed or Medium-Speed Wire EDM as more economical for general machining or cost-sensitive applications. The Wi-200S is a compact submerge-type wire-cut EDM with XYZ travel 210 / 200 / 155 for precision machining of small workpieces and high-accuracy metal components. The Wi-430S has XYZ travel 400 / 300 / 300 and a three-body independent design intended to provide more space, easier maintenance, and easier consumable replacement. The Wi-640S has XYZ travel 600 / 450 / 350 and is described as a large submerged wire-cut EDM with a wide processing range, high-precision cutting capability, and a listed standard 0.5-micron specification. JSEDM EDM machines are also described as precisely machining complex-shaped molds such as mobile-phone cases, laptop housings, and tablet back panels, and as performing fine machining on high-hardness materials to support mold durability and precision. JSEDM offers Wire Cut, CNC, and ZNC EDM machines in multiple sizes with customizable solutions.
