📍 Arrival — From subway line 7 5 minutes, Chunui Techno Park Building 102
5-minute walk from Subway Line 7. Room 906, 9th floor, Building 102, Chunui Techno Park, Chunui-dong, Bucheon. As soon as the elevator door opens, what you hear is the rhythmic sound of a cable crimping machine. After passing through the entrance, you will see a neatly organized workshop with traces of cables, harnesses, and connectors that have been used throughout the Korean electronics industry for about 33 years.
In October 1992, the company started by supplying cable and harness assemblies at a small store in Sewoon Shopping Center, Seoul. Now, it exports HD-SDI CCTV camera cables to Japan Pacific Trading and has become a precision parts manufacturer with UL E345766 certification. There's not much to brag about. Instead, the company motto “Reward for quality and delivery” is written all over the walls of the workshop.

⚙ Self-crimping lines — where hundreds of terminals are joined per minute
The heart of the plant is the automatic crimping line. A process of cutting wires to a certain length, stripping the ends, and joining them by crimping the terminals with precise pressure. Hyein Electronics owns KM Digital Automatic Pressing Machine and 10 Jiyoung Precision Terminal Pressing Machines and 60 Applicators, allowing it to process various terminal and wire combinations simultaneously.

🧑🔧 Manual pressing — precision assembly requiring human hands
“Machines can’t do it all. Prototypes, small orders and irregular terminals ultimately have to be pressed by hand.” This is the company's explanation. This is an area where the experience and taste of each worker go into. Various soldering irons and three RF CABLE soldering assembly tables are waiting for workers. The working knowledge accumulated over 33 years is the asset of this line.

📡 RF cable processing — responsible for signal integrity of communications equipment
The most interesting corner is the RF cable line. For high-frequency cables used in communication equipment, 5G base stations, CCTV HD-SDI, etc., signals are damaged even if the impedance matching, shielding loss, and connector coupling torque are off by just 1 to 2 degrees. Hyein Electronics possesses a Swiss-made RF CABLE stripper that strips the coaxial cable sheath, shield, and dielectric in stages to the correct length and then combines them with the RF connector through precise compression.
Obtained CCTV camera cable utility model patent in 2000, developed and mass-produced HD-SDI CCTV camera cable in 2010, started export to Japan Pacific Trading in 2012 — all these roads were made on this workbench.

💬 Core technology FAQ (excerpt from field interview)
Q. What is Hyein Electronics’ biggest strength?
A. (1) Specializing in cable and harness assembly for 33 years One well — from Seun Shopping Center in 1992 to the current Bucheon Chunui Techno Park. (2) 19 types of core equipment, including 60 applicators, automatic pressing machine, injection molding machine, and Swiss-made RF stripping machine. (3) Eligible for export with UL · IPX7 certification. (4) Manual know-how + automation line parallel to support prototypes, mass production, and small quantities.
Q. What areas do you supply to your customers?
A. Simultaneous delivery to 11 categories, including CCTV camera makers, semiconductor equipment manufacturers, factory automation (FA) system integrators, vehicle black box makers, communication equipment (5G/optical communication) manufacturers, IT peripherals, and toy manufacturers. HD-SDI cable exported to Japan Pacific Trade.
Q. Are waterproof connectors special?
A. From 2005 to 2007, we independently developed the 4P·6P waterproof connector and obtained IPX7 certification and design registration (in-house design patent). General connectors have limitations in outdoor CCTV and vehicle components, but Hyein Electronics' waterproof type is a product that fills that gap.
Q. Do you also accept prototype/small quantity orders?
A. it's possible. The automatic pressing line is for mass production, but a manual pressing and ironing workbench is operated separately, allowing single-unit prototypes to be produced. Irregular terminals, special lengths, and multi-branch harnesses can also be quoted by bringing drawings and samples.
Q. How to inquire about quotation/sample?
A. Representative phone number 032-348-8273 or email hielec2034@naver.com. Specifications can be checked in the product category of the website http://www.hielec.co.kr/. It is 5 minutes away from subway line 7, so visiting in person is welcome.
