About US
Our History
Founded in April 1983 under the name Yu Chang Instrument Industry Co., Ltd., our company was the first manufacturer in Taiwan to independently research, develop, and produce metallographic sample preparation equipment.
Throughout decades of changing market conditions and intense competition, we have continued to grow through our commitment to quality and innovation. In May 1996, the company was officially renamed Plusover Instrument Industry Co., Ltd., marking a new chapter in our development.
Backed by a team of experienced engineers and R&D specialists, we uphold the principles of integrity, quality first, prompt service, and customer satisfaction. These values have established us as a trusted and recognized manufacturer in the fields of metallographic sample preparation equipment and material testing equipment.
In recent years, we have made significant investments in the development of Rockwell, Vickers, and Brinell hardness testers to meet the diverse needs of customers across various industries. Our products have earned long-term trust and recognition from fastener manufacturers, heat treatment companies, automotive and motorcycle industries, as well as universities, research institutions, the Metal Industries Research & Development Centre (MIRDC), and SGS testing organizations.
Our Philosophy
At Plusover Instrument, we specialize in the manufacturing of metallographic sample preparation equipment and the development of material testing solutions. Our core focus is on stability, precision, and practical application.
From grinding and polishing machines, precision cutting machines, and mounting presses for metallographic sample preparation, to hardness testing equipment and screw penetration testing machines, we continuously optimize equipment performance, operational efficiency, and measurement accuracy to ensure our products meet the practical requirements of material inspection.
We place great importance on achieving consistent and reliable results for every critical specimen. Maintaining repeatability under different batches and environmental conditions is the foundation of high-quality material analysis.
We believe that the true value of material testing equipment lies in long-term stability and accuracy. Therefore, beyond manufacturing reliable equipment, we also provide continuous technical support and professional services, enabling our customers to focus on quality assurance and dependable testing results.
Service Process
We provide comprehensive solutions for metallographic sample preparation equipment and hardness testing equipment, with every process designed around practical customer requirements.
We begin by understanding the customer’s industry and application, such as fastener manufacturing, heat treatment, metal processing, and material analysis, allowing us to recommend the most suitable equipment.
For customized requirements, we further confirm detailed specifications and operating conditions, including metallographic sample preparation procedures and testing methods, ensuring that every solution is tailored to actual production and inspection needs.
Before delivery, all equipment undergoes thorough testing and adjustment. We also provide installation, commissioning, and operator training to help customers quickly achieve efficient operation.
Our after-sales services include technical support, equipment maintenance, and repair services to ensure long-term operational stability while reducing production and inspection risks.
Future Vision
As the manufacturing industry continues to move toward automation and digital transformation, Plusover Instrument remains committed to optimizing equipment design and operational processes.
In the future, we will focus on the development of automated testing systems, simplified operation, and data integration technologies to further improve the efficiency and consistency of material inspection.
At the same time, we will continue to strengthen our expertise in metallographic sample preparation and hardness testing, while expanding our presence in international markets and bringing high-quality Taiwan-made material testing equipment to customers worldwide.
