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.

Method for manufacturing nonwoven fabric using basalt fiber

● We use non-woven fabric to obtain nonwoven fabric, and this nonwoven fabric is used for automotive interior materials.
● Improved productivity : Increased mold durability by reducing mold edge wear when molding with cutting mold.
●After disposing of material, it is possible to dispose of it at high temperature to prevent the emission of harmful substances, and even if incinerated at a high temperature, the basalt fibers remain as incineration residues so that they can be recovered and recycled.

Apparatus for manufacturing sound absorbing materials for automobile silencers

● Sound absorbing material manufacturing equipment used for silencer of automobile - The manufacturing process is simple.
- It can save much time and manpower in production.
● Solve that the manufacturing process of the sound absorbent is complicated, and it is troublesome and the productivity is lowered.
● It does not waste much time and manpower in production.
● The glass fiber tangles with each other, causing it to swell, making it a crimp bulky yarn with excellent crimpability and bulky properties.
● The manufacturing equipment of the hermaphrodite system which packs the crimp bulky yarn into the designated packing container according to the weight requested by the customer.

Method of manufacturing thermoplastic composite

● In the production of thermoplastic composites in the form of parts or products using a thermoplastic resin combined with a thermoplastic resin and a reinforcing fiber, the manufacturing process is simplified and minimize the investment costs, and a method for manufacturing a thermoplastic composite material capable of forming a complicated shape and facilitating modification of a molding mold is provided.
● In the conventional open mold type, damage of the material generated when removing the thermoplastic material, rapid cooling of the material exposed to the room temperature during the movement between the processes, material loss due to deformation and extrusion of the fiber arrangement upon pressurization and complex manufacturing process occurs.
● By preheating and cooling molding, the thermoplastic resin melted in the preheating mold can be appropriately impregnated into the reinforcing fiber, thereby ensuring excellent moldability.

Sound absorbing material manufacturing equipment for automobile silencer

● A release guide and transfer guide for releasing a number of irradiated multi-stranded fiberglass yarns to the sound absorbing material manufacturing apparatus for automobile, a turn cable for the rotation jig device to be rotatable on the other side, and a nozzle assembly being.
● It is equipped with an automatic control unit and the control unit turns the turn cable at a preset speed and stops by the position detector.
● Stopping the turntable after decelerating, vertically dropping the nozzle assembly. Compressed air is injected into a number of nozzles to form crimp bulky yarns in the nozzle section.
● When it reaches a certain amount, the nozzle assembly is vertically raised after cutting, and the turntable is controlled to rotate at the table speed again.
