UCHI Industrial was established in 1990. Chairman Zhuang Mingxiong rented the factory in Yongkang of Tainan City, and engaged in line generation OEM. He developed the foundation of UCHI industry. In 1999 in Jia Li District of Tainan City (Jiari Industrial Zone), Chairman relocated the factory, updated production equipment, and raised production capacity.


high-tech :
EBNER HICON/H2 Bell annealers

In 2015, we imported the Austrian EBNER HICON/H2 full hydrogen bell annealing furnace machine, which has accurate temperature and time control system, it improves the quality of products. UCHI is the industry leader in the field, showing the international standards on quality.

Main Products

Carbon Steel

Carbon Steel

There are 1018, 1022, 1035 types of carbon steel. It's widely used for screw bolts and other fastener products.

Baron Steel

Baron Steel

Adding boron can improve the plasticity of steel. It has high hardness and wear resistance, and widely used for strength 8.8 and 10.9 grade screw products.

Alloy Steel

Alloy Steel

Strengthen the mechanical properties of steel by adding alloy elements. It extend the service life of steel and keeps the surface of steel bright and beautiful.

Chrome Molybdenum Alloy Steel

Chrome Molybdenum Alloy Steel

Strengthen the mechanical properties of steel to increase the strength and toughness, and improve wear resistance and heat resistance.

Equipment & Quality Control


Use the method of atmospheric pressurization, separate gas by different diffusion rate. Extraction of high purity nitrogen (N2) and storage in a gas tank for use.

Pickling & Coating

With immersion hydrochloric acid and water to remove the oxide film, and then bonderizing metal surface. Increase the metal lubricity and wear resistance, and make the wire surface smooth.

Annealing Furance

Heating metal with high temperature to transform and soften metal structure, for the process of line drawing and cold forging. It makes carbon uniformly distributing in metal.


EBNER HICON/H2 has precise temperature / time control and full hydrogen gas protection in furnace. It effectively enhances the mechanical properties and surface quality of metal wire.

Straight Line Wire Drawing Machine

High efficiency, low noise and high stability machine. It produces smooth surface and accurate diameter Wire.

Vertical Type Wire Drawing Machine

Producing larger diameter (800-1300mm) of wire. High quality and stability wire drawing. We produce forward or reverse wire according to customer demand.

High Efficiency Wire Drawing Machine

Producing small diameter (600-800mm) of wire. High efficiency machine, large output and rapid delivery.

Tensile Testing Machine

Detecting mechanical properties of steel wire, such as tensile strength, volatility, elongation, etc., with different tools, it can do stretched, compressed and other tests.

Precise Grinding Machine

Cutting, grinding and burying metal wire or screw fasteners or other products to get the metal slice for accurate testing.

Vickers Hardness Tester

Product quality control. Detecting metal hardness (HV), and observing microstructure and carbon distribution of metal by microscope.

Rockwell Hardness Tester

Product quality control. Detecting metal hardness (HR), and has wide range of material and hardness testing.
