Apparatus for manufacturing sound absorbing materials for automobile silencers

● Pads for car engine hoods - Excellent sound absorption effect.
- Maximize recycling of material. 　

● Blend polyester fibers and low-melting point polyester fibers.
● After mixing, carding and thermoforming to obtain matte primary product.
● The first products are laminated in multiple layers and then heated so that they are mutually heat-sealed, cold-formed at the same time, and trimmed to produce products.

Crimp burky yarn for sound absorbers used in automobile muffler silencers

● About crimp bulky yarn for buckling used in automobile mufflers and silencer filled with crimp bulky yarn. - Excellent sound absorbing effect.
- It is easy to make, easy to handle, and glass fiber does not scatter during use. 　

● Blend polyester fibers and low-melting point polyester fibers.
● After mixing, carding and thermoforming to obtain matte primary product.
● The first products are laminated in multiple layers and then heated so that they are mutually heat-sealed, cold-formed at the same time, and trimmed to produce products.

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.

Cutting inorganic fiber mat and manufacturing method

● 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.

● 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.
●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
