Our Processes and Materials

OKey-KO Parts

At OKey-KO Co., Ltd, we offer a comprehensive range of manufacturing processes and materials to meet the diverse needs of our clients. From investment casting to CNC machining, our expertise and state-of-the-art facilities ensure high-quality production and timely delivery.

Investment Casting

Investment Casting

Investment casting involves creating a wax model, which is coated with ceramic to form a mold. Once the mold is made, molten metal is poured into it to create precise and complex parts.

Sand Casting

Sand Casting

Sand casting uses a sand mold to form metal parts. It is a versatile process that allows for the production of large parts and complex shapes with excellent mechanical properties.

Cold and Hot Forging

Forging

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Cold forging is done at room temperature, while hot forging is done at high temperatures to increase malleability.

Extrusion and Steel Profile

Extrusion

Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed or drawn through a die to create long pieces of material in different shapes.

Rubber Moulding and Injection Moulding

Injection Moulding

Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. Rubber molding uses this technique to create rubber parts with precision.

Sintering and MIM

Sintering

Sintering involves compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. MIM combines plastic injection molding and powder metallurgy.

NCT/Die Stamping - Laser - Tube Bending - Welding

Stamping

These processes involve shaping and cutting materials using techniques such as laser cutting, tube bending, and welding to create intricate and precise components.

CNC Turning, Milling, and Grinding

CNC Machining

CNC machining uses computer-controlled tools to remove material from a workpiece to create a desired shape. Processes include turning, milling, grinding, and more.

Surface Treatment

Surface Treatment

Surface treatments such as anodizing, plating, and coating enhance the appearance and durability of parts, providing corrosion resistance and other desirable properties.

Assemblies and Testing

Assemblies and Testing

Our assembly and testing services ensure that all parts are assembled correctly and function as intended, meeting the highest quality standards.

Special Gears, Springs, Bushings, Screws, and Magnets
