Lightweight multi-layer car sunshade board

● Lightweight multi - layered automotive sunshade board. (sunshade Board). - It is light, but has excellent strength and mechanical properties.
- Provision of high quality products to shorten the process.
● GOM is obtained by mixing glass fiber and polyolefin fiber.
● Preheating the GOM, placing the high-density foam sheet between the GOMs and pressurizing them to obtain a molded material that is integrally bonded.
● Cold forming of the molding material to form necessary products, and if necessary, the skin material is placed on the outside of the GOM during cold forming, and the molding is made to be integrally joined by molding.

Flexible pipe manufacturing equipment

● A flexible tube manufacturing apparatus, in particular, a flexible tube manufacturing apparatus in which a plurality of parts are integrated into one system. - It is a useful tube to be used anywhere, especially in the engine room where the internal heat is rising due to the improvement of the engine performance.
● Due to the improvement in engine performance, the heat inside the engine room is increasing. By installing a flexible tube with heat insulation required for each environment by combining various materials in the engine room, it is possible to delay the oxidation corrosion of the heat- It plays a role to increase vehicle durability.
● Manufacturing method: Piping → Drying → Rolling → Damping → Cutting process

Cutting inorganic fiber mat and manufacturing method

● The inorganic fiber yarns were cut into one cutting roller portion having a length similar to the width of the lower conveying belt, and then dispersed by a dispersing device, and dropped on the conveying belt with low-weight releasing fibers, and after spraying water on the surface of the dispersed low-weight open-cut fiber yarns to increase the adhesive strength, the powdery binder system is dispersed and sprayed. Then, the pad is manufactured by heating and cooling.
● The web glue applied to produce the cut fiber mat is not produced domestically, and all of them have to be procured from overseas, thus eliminating the problem of rising prices of products.
●Using glass fiber, basalt fiber and inorganic fiber yarn, make inorganic fiber mat by Textile cutting and dispersion → Water spray process → Powder adhesive dispersion spray → Heating → Cooling → Winding → Cutting.

Noise protection pads for automobiles

● Improvement of noise prevention pad which is installed at the top of car engine room to effectively block various noise generated from engine room.
● Improvement of a noise prevention pad which effectively blocks various noises generated from the engine room to correct the conventional shortcomings.
● A glass fiber mat was placed on the nonwoven fabric, and an aluminum plate was placed thereon. Then, the nonwoven fabric, the glass fiber mat and the aluminum sheet were integrally formed by hot pressing.

Car battery cover

● The high heat generated from the engine is prevented from being transmitted to the electrolyte filled in the battery, so that the normal performance of the battery can be maintained for a long time. - When the electrolyte is maintained at 50 ° C or higher, the battery durability tends to decrease drastically, so we resolve this.
- Battery Warranty Dissatisfied Resolved.
● A body composed of an inner skin and an outer skin joined together by a heat insulating material, and the body is pressed with a press die to mold the battery cover in a developed form, and after the developed molded parts are superimposed, the connection part is riveted so that the rectangular battery cover can be formed and the battery cover can be covered on the outer surface of the battery.

Side insulator and manufacturing method thereof

● Side insulators, manufactured in various plate shapes, are additionally installed in the lower part of the cap and the engine room frame to prevent the heat and noise from the engine from penetrating into the driver's seat. - Easy to assure quality at gap step during assembly. .
● The sound absorption material and the rigid stiffener are integrally formed by pressing in place of the conventional structure in which the cover and the sound absorbing material are separately manufactured, so that the production cost can be reduced.
● Since the molding is performed in the state where the compression is performed, the thickness of the product can be reduced.
