Terminals & Connectors

K.S Terminals Inc. is a global leader in the production of electrical cold-pressed electrical terminals. It was established in Changhua, Taiwan in 1973, leveraging high-precision mold design, stamping, and injection molding as its core technologies.

In 2002, KST became a publicly listed company on the Taiwan stock market. Its core business values have proven to be sustainable as KST continues to strive to build integral relationships with partners who share a common commitment to quality, research & development. At present, KST has five factories in Taiwan and one factory in Suzhou, China.

In 1988, KST established the Zhangbin factory and headquarters in the Changhua Binhai Industrial Zone. It is the main production base of KST, which is dedicated to manufacturing our electrical terminal and connector product lines. KST has many manufacturing processes, with varying degrees of automation for continuous stamping, welding, electroplating, assembly packaging, and warehousing.


Automatic welding machine and CCD inspection ensure 100% yield.

We also have a mold processing center dedicated to working with customers to design and develop their product tooling.

Customizable Automation

Our automation engineering team designs and produces automation equipment, including automatic feeding, assembly, CCD screening, inspection, counting and packaging, that allow us to yield products of consistent quality and quantity. Automation equipment and processes can be quickly integrated and configured to produce a wide range of products, promoting flexible production, and expedited shipping that meet customer delivery requirements.

From large wire terminals for power transmission to small electronic connectors for electric car charging guns, about 3.8 billion PCS and more than 20,000 types of connectors are produced and shipped from this factory every year.

More than 45 years of experience, advancement in production technology, complete certified standard laboratories, ensure product quality and safety, create KST brand awareness as global leader in the terminal and connector market.

Automation Workshop

ISO 14001

There are more than 300 automated assembly machines in the factory dedicated to various types of terminals and connectors. These assembly machines have been developed by our automation team and they have been designed to boot up quickly, be simple to maintain, and yet be highly flexible in usage.

Step 1

Raw Copper Materials

ISO 14001

Incoming Quality Control  (IQC), material inspected for visual appearance, hardness, conductivity, size and direction confirmation

Step 2

Stamping Press


A fully automatic mechanical feeder is used to place the copper material into the mold for stamping and forming at high speed. The size tolerance is maintained automatically via CCD Inspection.

At present, there are about 41 stamping presses. The annual production output for stamped products is about 1.5 billion pieces. Stamped products range in size from a minimum of 6 mm to a maximum of 150 mm.

Step 3

Annealing & Welding

Automated, CCD Inspected

An automatic annealing & welding machine is used to weld the terminal and automated CCD inspection is used to ensure 100% product yield.

Step 4


ISO 14001

KST’s electroplating factory is located in the National Industrial Environmental Zone. It supports fast, high-quality electroplating surface treatments. Production processes are in full compliance with government environmental regulations and emission standards.

Step 5

CCD Inspection


The finished product passes between vibrating plates, and the CCD Inspection machine can automatically detect the defective appearance of products.

The Automation Department engineer codes programs to detect abnormal quality products through PLC (programming logical controller) signals and automatically returns the materials to the defective products area.

Step 6

Terminal Assembly Machine

Automated, CCD Inspected

Automatic assembly equipment is used to insert the terminal into the insulating sheath, and CCD inspection/detection is used to ensure product tolerances and quality specifications are met.

Step 7

Terminal Reel Assembly

Automated, CCD Inspected

Automatic assembly equipment is used to place the assembled terminal onto the reel tape, and CCD inspection/detection is used to ensure product tolerances and quality specifications are met.

Step 8

Connector Assembly

Automated, CCD Inspected

Automatic assembly equipment is used to insert the terminal into the connector, and CCD inspection/detection is used to ensure product tolerances and quality specifications are met.

Step 9


Manual & Automated

Fully automatic packaging machines can execute one-stop processes for picking, weighing, encapsulating, labeling, and barcode printing. It can not only significantly enhance packaging productivity and efficiency, but also ensure the stability and consistency of package quality.

Step 10


Manual & Automated

Linked to the production order management system in ERP, the label printing system can fetch product specifications and customer shipping information from the synchronized database. It can print product labels for bags, boxes, cases, pallets, crates, and custom documents efficiently.

Step 11

Finished Product OQC


Products undergo Outgoing Quality Control (OQC) including optical inspection,  quantity confirmation,  as well as various electrical and performance testing.

Step 12

Continuous Improvement

ISO 14001

Continuous improvement is the ongoing improvement of products, services, or processes through incremental and breakthrough improvements. These efforts can seek “incremental” improvement over time or “breakthrough” improvement all at once.
