Method and apparatus for nonwoven trim panels
A method of forming a trim panel is provided. The method including the steps of: placing a non-woven mat of material in a heating press; heating the material to a predetermined temperature; applying a decorative film to a first surface of the heated material to create a bilaminate; placing the bilaminate layer into a cavity of a tool such that the decorative film is facing the cavity; heating the cavity; and injecting a thermoplastic resin into the tool such that the thermoplastic resin is adhered to a second surface of the material, the second surface being opposite to the first surface.
1. A method of forming a trim panel ( 38 ), comprising:
placing a non-woven mat of material ( 12 ) in a heating press ( 16 );
heating the material ( 12 ) to a predetermined temperature;
applying a decorative film ( 18 ) to a first surface of the heated material ( 12 ) to create a bilaminate ( 26 );
placing the bilaminate ( 26 ) into a cavity ( 32 ) of a forming mold ( 28 ) such that the decorative film ( 18 ) is facing the cavity ( 32 );
heating half of the cavity ( 32 );
closing the forming mold ( 28 ); and
injecting a thermoplastic resin ( 33 ) into the forming mold ( 28 ) having a heated cavity such that the thermoplastic resin is adhered to a second surface of the material ( 12 ) which is part of the bilaminate, the second surface being opposite to the first surface.
2. The method as in claim 1 , wherein the decorative film ( 18 ) is applied to the material via a contact roller ( 20 ) of a roller system ( 22 ).
3. The method as in claim 1 , wherein the decorative film ( 18 ) is perforated.
4. The method as in claim 1 , wherein the decorative film ( 18 ) consists of a layer of thermoplastic olefin laminated to a layer of foam.
5. The method as in claim 1 , wherein the decorative film ( 18 ) is a thermoplastic olefin.
6. The method as in claim 1 , wherein injection pressures of the thermoplastic resin ( 33 ) are limited using sequential valve gating, foaming agents, or flow enhancers in order to reduce injection pressure.
7. The method as in claim 1 , further comprising opening and closing the mold ( 28 ) prior to injecting the thermoplastic resin ( 33 ).
8. The method as in claim 1 , wherein the predetermined temperature is in the range of 200-210 degrees Celsius.
9. A method of forming a trim panel ( 38 ), comprising:
placing a non-woven mat of material ( 12 ) in a heating press ( 16 );
heating the non-woven mat ( 12 ) to a predetermined temperature;
heating half of a cavity ( 32 ) of a forming mold;
inserting a decorative film ( 18 ) in the cavity ( 32 ) of the forming mold ( 28 );
removing the heated non-woven mat from the heating press and inserting between a half of the forming mold and the decorative film such that a first surface of the non-woven mat contacts the decorative film, wherein inserting the decorative film occurs after heating the cavity;
closing the forming mold ( 28 ); and
injecting a thermoplastic resin into the forming mold such that the thermoplastic resin is adhered to a portion of a second surface of the material, the second surface being opposite to the first surface.
10. The trim panel as in claim 9 , wherein the decorative film ( 18 ) is perforated.
11. The method as in claim 9 , wherein the decorative film ( 18 ) consists of a layer of thermoplastic olefin laminated to a layer of foam.
12. The method as in claim 9 , wherein the decorative film ( 18 ) is a thermoplastic olefin.
13. The method as in claim 9 , further comprising heating the decorative film ( 18 ) prior to placement in the cavity ( 32 ) of the forming mold ( 28 ).
14. The method as in claim 9 , further comprising heating the decorative film ( 18 ) after placement in the cavity ( 32 ) of the forming mold ( 28 ) but prior to inserting the non-woven mat.
15. The method as in claim 9 , further comprising opening and closing the tool ( 28 ) prior to injecting the thermoplastic resin ( 33 ).
16. The method as in claim 9 , wherein the predetermined temperature is in the range of 200-210 degrees Celsius.
17. A method of forming a trim panel ( 38 ), comprising:
placing a non-woven mat of material ( 12 ) in a heating press ( 16 );
heating the material ( 12 ) to predetermined temperature;
applying a thermoplastic topcoat ( 44 ) into a cavity ( 32 ) of a tool ( 28 );
heating half of the cavity ( 32 );
placing the material ( 12 ) into the heated cavity ( 32 ) such that a first surface of the material is adhered to the thermoplastic topcoat ( 44 );
closing the tool ( 28 ); and
injecting a thermoplastic resin ( 33 ) into the tool ( 28 ) such that the thermoplastic resin is adhered to a second surface of the material ( 12 ), the second surface being opposite to the first surface.
18. The method as in claim 17 , wherein the topcoat ( 44 ) is sprayed into the cavity ( 32 ).
19. The method as in claim 17 , further comprising opening and closing the tool ( 28 ) prior to injecting the thermoplastic resin ( 33 ).
20. The method as in claim 17 , wherein the predetermined temperature is in the range of 200-210 degrees Celsius.
