Problems solved by technology

[0003] The skin coating process is to directly cover the leather or PU skin on the plastic skeleton. This process was originally used in luxury passenger cars to create a luxurious interior. The coating process makes up for the defects in the appearance of the slush foaming process. but lack of compression

Embodiment Construction

[0021] see figure 1 , the embodiment of the present invention comprises: a kind of PU spray foam instrument panel cladding process, concrete steps include:

[0022] Step 1: Injection molding of instrument panel body frame 1.

[0023] Step 2: Foam the instrument panel body frame 1 in step 1 and paste it together with PU spray4. Compared with slush-molded skin, PUspray4 is more environmentally friendly, and replacing slush-molded skin with PU spray4 greatly improves the safety of passenger cars .

[0024] Step 3: Spray glue on the instrument panel body frame 1 that has been glued with PU spray 4 in step 2.

[0025] Step 4: Paste together the instrument panel body skeleton 1 with PU spray4 and 3D-mesh2 sprayed with glue in step 3, and paste the glue-sprayed surface of instrument panel body skeleton 1 and the glue-sprayed surface of 3D-mesh2 , 3D-mesh2 improves the feel of the product.

[0026] Step 5: Spray glue on the instrument panel body frame 1 and the surface of the skin...

Abstract

The invention discloses a PU spray foam instrument board cladding process. The process comprises the specific steps of (1) injection molding of an instrument board body skeleton; (2) conducting foaming on the instrument board body skeleton obtained in the step (1) and bonding the instrument board body skeleton to a PU spray; (3) spraying glue onto the instrument board body skeleton obtained in the step (2); (4) bonding the instrument board body skeleton obtained in the step (3) to a 3D mesh; (5) spraying glue onto the instrument board body skeleton obtained in the step (4) and the skin; (6) bonding the instrument board body skeleton obtained in the step (5) to the skin; (7) conducting hot pressing on the instrument board body skeleton obtained in the step (6); and (8) conducting edge covering on the instrument board body skeleton obtained in the step (7). In this way, the PU spray foam instrument board cladding process integrates the advantages of the slush molding foaming process and the skin cladding process, the luxurious appearance is created, and the soft pressing performance is realized.

Description

technical field [0001] The invention relates to the field of automotive interior dashboards, in particular to a PU spray foamed dashboard coating process. Background technique [0002] The existing soft decoration technology of automobile dashboard generally includes slush molding foaming and skin coating. Slush molding technology has been in my country for more than ten years. It is very popular in passenger cars, but it can no longer meet the aesthetic requirements of consumers. Slush plastic foaming is to inject foaming liquids A and B between the instrument panel skeleton and the slush plastic skin, and then fill the entire instrument panel through the irreversible chemical reaction between A liquid and B liquid. The slush plastic foaming process makes the automobile dashboard Soft and pressable, not a hard plastic surface, but the disadvantage of this process is that the slush-plastic skin is subject to large temperature changes. The surface is too soft when the temperatu...
