Case Study

Fastener manufacturer significantly increases quality with PLM

Samjin Precision Manufacturing

Samjin extends its PLM approach, adding Teamcenter to Solid Edge; realizes higher product quality, lower development costs and increased competitive advantage

Knowledge re-use and document management

Samjin Precision Manufacturing (Samjin), founded in 1973, manufactures automobile and industrial fasteners, forged components and fastener manufacturing equipment. In addition to automobiles, Samjin supplies fasteners for a variety of other applications, including home appliances, industrial machinery, ships, high-rise steel frame buildings, bridges, railroads and steel transmission towers.

Having concentrated for decades in one area, Samjin has become recognized for its technical expertise. In its industry sector, based on revenue, Samjin ranks first among businesses in South Korea and is a top-ten company globally. Samjin has 300 employees.

It is natural for a fastener business to have hundreds of different fastener models. Having created many new products over the course of several decades, Samjin has a wealth of product data, and management wanted to do a better job of re-using and leveraging that information. Samjin also had difficulties with document management that it needed to address. Design and production documents were managed separately in paper format by different departments (sales, research and development, quality control and production). It was difficult to know which versions were current. Samjin tried to manage documents using its enterprise resource planning (ERP) system in combination with a proprietary solution developed in-house, but this approach fell short of management expectations.

Fast and effective product data management implementation

Having seen competitors successfully address such issues with product data management (PDM) systems, Samjin decided to evaluate this technology for its own use. In addition to better data management, the company wanted to reduce the amount of time spent searching for information, and prevent omissions when distributing design information and technical documents.

During the evaluation process, the company looked for product lifecycle management (PLM) software that was easy to use, able to manage a large amount of data, and compatible with its computer-aided design (CAD) system (Solid Edge® software from Siemens PLM Software). Teamcenter® software, preconfigured for rapid deployment and fast return on investment, also from Siemens PLM Software, met these criteria.

Before installing Teamcenter, Samjin analyzed the needs of its users. An experienced project manager was aware of companies where employees didn’t take full advantage of their PLM technology, because either they didn’t learn how to use it effectively or it wasn’t adapted to their needs. “We were determined to avoid these mistakes and make the best use of Solid Edge and Teamcenter,” says Dong Chool Kwon, general manager at Samjin.

The company divided the Teamcenter implementation into stages: drawings and bill of materials (BOM) management, document management, project management, workflow management, ERP interface management and design change management. The system was completely set up and in use within six months. Now, designs created using Solid Edge with synchronous technology are managed with Teamcenter,and the information can be viewed by all departments. It can be sent to partners as well.

Improved competitive position

Samjin has experienced significant benefits through the use of Teamcenter, including a reduction in the defect rate, faster decision-making and lower product development costs. The reduction in defects is a result of better data management that allows everyone to work with accurate, up-to-date versions of product information. The faster decision-making comes from the improved collaboration made possible by wider access to product data across the organization. The cost of product development, which is down about 30 percent, is principally the result of greater design re-use, fewer purchases of duplicate parts and less downtime on the manufacturing floor due to the defect reduction.

In addition, the quality of Samjin’s products has greatly improved since implementing Teamcenter. Samjin scored high in its quality certification rating, realizing a 30-point gain since its last evaluation. This, in conjunction with a reduction in cycle times, has increased the company’s overall competitiveness. “All of these changes have impressed our major client, Hyundai Kia Motors, which recently recognized us as an outstanding partner company,” says Kwon.

“We are seeing exceptionally positive outcomes as a result of using Teamcenter for our product data management needs,” adds Kwon.
