Defense business division

Guided Weapon/ Aerospace Launcher Composite Parts

Using 'Carbon/Phenolic' and 'Phenolic molding compound' materials for high-temperature structures, heat-resistant materials in MLRS nozzle parts are developed and produced.

'Carbon/BMI' and 'Glass/BMI' materials are used to make gas turbine engine parts for aviation/guided weapons and ‘Glass/Epoxy’ and ‘Composite sandwich panels’ are used to make radomes.

These materials satisfy MIL-STD and have excellent features of lightweight, high strength, and high heat resistance (Tg=300'c), which expand to the following aerospace field and high-speed guided weapons.

The linear motor-operated free piston system is not only the highest level of improvement in the existing system but also has room for future design improvements.

The feature is energy savings, quiet with low vibration, and enhances performance so that the piston pump operates very stably, thereby extending the life cycle.

The technical principle is to generate mechanical resonance simultaneously with the electromagnet, return spring, and input current instead of operating as a piston in the cylinder.

The existing compressor compresses air by converting the rotational motion of the motor into a linear motion, resulting in about 20% energy conversion loss.

But the linear compressor adopts a linear method in which the motor moves linearly and has no energy loss and no connection that causes friction and wear, which can significantly reduce noise.

Principle of operation

1When voltage is applied, the electromagnet pulls the piston, compressing the return spring, and refrigerant flows into the cylinder through the open inlet valve.

2When the electromagnet loses voltage, the return spring pushes the piston back, which expels the compressed refrigerant out of the cylinder through an open valve.

Other Business Division

Other Business Division and various business opportunities

We use composite materials and apply them to various industrial fields.

We are proceeding with the mass production of automobile parts and developing composite components for marine and mobile.

Lightweight, high fatigue resistance, higher tensile strength, corrosion resistance, vibration damping characteristic, and x-ray permeability are representative features of CFRP composite that make it subsidiary materials indispensable to the Metals’ limitation.

So, we are providing our composite solutions to valuable companies variously to the efforts for sustainable futures together.

Also, we support splendid partners in more diverse industries of aerospace, UAM, robots, medical devices, personal mobility, and renewable energy.

Process Overview

Autoclave Molding

Filament Winding Molding

Resin Transfer Molding

Press Molding

Autoclave molding is

a manufacturing method that uses various sub-materials to form under pressure and vacuum. Although the production process is long and the equipment is expensive, it has the advantage of producing highly reliable products. The stress and emptiness applied to the product can make the interlayer bonding of the material ideal, making it possible to have optimal molding conditions for composite materials and to produce products with excellent mechanical properties. We recommend this process for high-reliability products, such as aviation parts.

Filament winding is

a process where fibers are impregnated with resin, wound around a rotating mandrel, and hardened. It is advantageous for producing cylindrical products such as pipes, and we recommend this process for products that require muscular strength and strong tensile force because fibers are continuously input.

The RTM process(Resin Transfer Molding) is

a method of manufacturing products by laminating fibers on a press mold and injecting resin using an injection device. From prototype development to product production, we have a wide range of design experience required for RTM, so we have the technology to produce complex molded parts quickly.

The pressing process is

mainly for flat plate molding of composite materials, but we use this in various ways for molding curved products using molds. Our company manufactures precision molded products by adding multiple functions, including pneumatic and vacuum, to the pressing process and produces products using the optimal press molding method to prevent the fiber from sliding even at a low viscosity.
