Taking Green Manufacturing to the Next Level - SEYI's Servo Presses CE Certified by TÜV Rheinland

Electric vehicles (EVs) have become the talk of the market in recent years due to climate change. The servo presses produced by Shieh Yih Machinery Industry Co., Ltd. (SEYI), a type of green stamping machinery used for stamping metal parts by EV makers, recently obtained EU CE certification in accordance with the Machinery Directive, Low Voltage Directive, and Electromagnetic Compatibility Directive. SEYI is, therefore, the first servo press maker in Taiwan to complete the certification process with TÜV Rheinland.

SEYI is a global leader in servo press equipment, and has customers from metal parts for the automotive, aerospace, medical device, agricultural machinery, consumer electronics, building hardware, and domestic appliance industries. Tier-1 auto parts manufacturers in the US, Europe, and Japan have also become customers for medium and large SEYI servo presses in recent years. In the future, SEYI will focus even more of its energy on high-value, advanced smart servo manufacturing solutions.

A servo press production line consumes just 50% compared to a conventional stamping press, so carbon emissions during production are greatly reduced. Composite materials used by new energy vehicles (NEVs) are challenging to shape. The power servo and control systems of a SEYI servo press can be configured to deliver the most appropriate pressure curve for increased output and improved quality. In the future, metal forming production methods must not only balance output and capacity but also take environmental friendliness into account. SEYI is continuing to develop green servo press products aimed at providing end customers with safe and friendly production equipment.

The stamping press is classified as dangerous machinery. CE certification requires compliance with a number of related directives and third-party assessments. CE certification for industrial machinery generally consists of three key directives: the Machinery Directive (hazard identification guidelines/stamping press standards/safety circuits), Low Voltage Directive (electrical regulations for machinery), and Electromagnetic Compatibility Directive (no electromagnetic interference with other equipment). Certification in accordance with all three key directives is essential to ensuring the overall standard of the safety performance of dangerous machinery from design through to operation and reducing danger during use. Certifications can be looked up in the TÜV Rheinland Certipedia database to provide foreign buyers with additional assurance on the quality of machinery.

ESG is now a global trend. The specially designed servos installed in SEYI servo presses deliver low RPM, high torque, and low energy consumption. Electricity can also be recovered for reuse. SEYI Executive Vice President Joseph Liu says: "Take the 12,000 kN servo press, for example. If each machine runs for 24 hours a day and 312 days a year, the carbon emissions of the SEYI servo press are about 555 tonnes lower than for a hydraulic press. This is equivalent to the amount of carbon absorbed by 1.5 Daan Forest Parks in Taipei (approx. 92 acres) in one year. It provides production capacity while delivering environmental sustainability, energy efficiency, and carbon reduction. The industry, therefore, makes a contribution to the overall well-being of the planet."

EN ISO 16092-1 has now replaced EN 692 as the new standard for presses, and imposes more stringent safety requirements. SEYI has set an example for the rest of the industry by taking the lead on adopting the new standard. A rigorous and comprehensive safety assessment and verification process was conducted by TÜV Rheinland for SEYI's servo presses. The process encompassed training, technical meetings, corrective actions for deviations, and preparation of the Technical Construction File (TCF). SEYI and TÜV Rheinland overcame various technical challenges during the verification process so that the machinery could ultimately be certified as compliant with the requirements of EU directives.

TÜV Rheinland is an EU-approved independent certification body and the chosen certification body for many leading brands. From the functional safety of components to the systemic safety of industrial machinery and equipment, TÜV Rheinland can assist vendors in enhancing their conformity on mechanical safety requirements and risk reduction. Safety assessments for plants/production lines as well as personnel training services are also available. This includes obtaining Taiwan's TS safety mark and conformity with the local requirements of export markets anywhere in the world. Green manufacturing is now the new paradigm, and businesses are investing in the development of green production processes by starting with equipment. Digital technologies are also being applied to track energy consumption and carbon management, serving as another way for businesses to boost their green competitiveness.
