Our product line has grown from early-generation electrical terminals and connectors into a comprehensive portfolio serving diverse industries, spanning automotive, agriculture, machinery, transportation, power distribution and transmission, and the ever-expanding green energy sector.
The R&D department consists of more than 60 dedicated professionals responsible for defining and executing mid- to long-term product development strategy, covering new product creation, advanced process technology and equipment adoption, new material research, process improvement, and design talent development.
We strengthen our design and manufacturing capabilities for products, molds, and fixtures with engineering drafting and analysis software, and have implemented a PLM (Product Lifecycle Management) system that significantly improves the efficiency of managing product development cycles and technical data.
With 50 years of product development experience and deep mold design expertise, we have achieved IATF 16949 certification and built our quality assurance approach around Advanced Product Quality Planning (APQP), identifying and mitigating risk at every stage of development.
KST manages new product introduction through the five phases of APQP, identifying risk at each stage in advance to ensure our products consistently meet customer expectations.
When a customer needs to introduce a new product or redesign a mature one, careful upfront planning is essential even before design discussions begin. This phase focuses on understanding customer needs and product expectations, gathering key data, proactively defining requirements, and refining product characteristics through collaborative discussion.

Product design and development — or design changes for production — become the primary activity. A Design Failure Mode and Effects Analysis (DFMEA) is created to support design decisions.

This phase plans the manufacturing process for producing a new or improved product, balancing product specifications, quality, and production cost while designing the process. The process must be capable of producing the required quantity efficiently.

Validation is performed for the product, process, or any production changes. A significant production trial run is conducted to confirm that the final product and process can consistently produce conforming parts at the required rate under normal production conditions, culminating in customer approval through the Production Part Approval Process (PPAP).

Continuous improvement of products and processes, focused on safety, quality, delivery, and cost, feeding validation results back into earlier phases to close the loop.

R&D is the cornerstone of KST’s sustainable growth strategy. Beyond developing forward-looking products, it encompasses setting mid- to long-term goals — advancing safer, more environmentally responsible materials, processes, and equipment — and building an engineering culture centered on mentorship, training, and professional growth.
