Embodiment 1

[0057] A process for imitating leather on the surface of a trim panel in a car door panel, comprising the following steps (see figure 1 shown in the flowchart):

[0058] A. Choose Faux Leather:

[0059] The imitation leather with excellent appearance and texture is selected as the decorative layer raw material of the decorative panel workpiece in the car door panel. The physical properties of the imitation leather with excellent appearance and texture are as follows: the thickness of the skin is 0.45-0.47mm, and the longitudinal tensile strength is: 10KG / cm, transverse tensile strength: ≥9KG / cm, longitudinal elongation at break: 170-190%, transverse elongation at break: 140-160%, longitudinal tear strength: 9KG / cm, transverse Tear strength: 7.5KG / cm, foaming ratio of foam layer: 25-30 times, skin forming temperature: 160-170°C / 30 seconds;

[0060] B. cropping:

[0061] Cut the selected imitation leather into the specified size;

[0062] C. bake:

[0063] Place the imit...

Embodiment 2

[0076] A kind of imitation leather process for the surface of the decorative panel in the door panel of a car, the basic steps and the mold used are the same as the first embodiment, but the relevant parameters are different: the step C. The heating temperature during baking is 350° C., and the heating time is set to 42 seconds; step F. The cooling time during cooling is 8 seconds; the diameter of the blister hole is φ1 mm, and the distance between the blister holes is 10 mm.

Embodiment 3

[0078] A kind of imitation leather process for the surface of the decorative panel in the door panel of a car, the basic steps and the mold used are the same as the first embodiment, but the relevant parameters are different: the step C. The heating temperature during baking is 370° C., and the heating time is set to 45 seconds; step F. The cooling time during cooling is 20 seconds; the diameter of the blister hole is φ1.5 mm, and the distance between the blister holes is 18mm.

Abstract

A surface imitation leather process for an intermediate decorative plate of an automobile door plate relates to a processing technique of automobile fittings and comprises the following steps: A, selection of imitation leather; B, cutting; C, baking: the imitation leather is placed between an upper heating plate and a lower heating plate and is baked via heating, the set heating temperature of the two heating plates is 350-370 DEG C, and the heating lasts for 40-45 seconds; D, glue spraying: a layer of glue is uniformly sprayed on the surface of the work piece of the intermediate decorative plate of the automobile door plate; E, vacuum plastic absorption: the work piece of the intermediate decorative plate of the automobile door plate is placed in a plastic absorption mold and is covered with the imitation leather, the periphery of the imitation leather is tightly pressed, and vacuum-pumping is performed to enable the imitation leather to cling to the surface of the work piece of the intermediate decorative plate of the automobile door plate; and F, cooling: after the cooling lasting for 8-20 seconds, the imitation leather is taken out, as a result, the finished product of the intermediate decorative plate of the automobile door plate is obtained. The surface imitation leather process can reduce the epidermal tension of the imitation leather, avoids the generation of phenomena such as bulging and pattern weakening, greatly improves product quality, achieves a strong appearance texture, and can improve qualification rate of the products to a great extent.

Description

technical field [0001] The invention relates to a processing technology of auto parts, in particular to a process of imitating leather on the surface of a trim panel in a car door panel. Background technique [0002] The middle trim of the door panel of a car is a relatively important component part of the door guard assembly, and plays a decisive role in the aesthetics of the vehicle interior. The surface is covered with fabric or artificial leather or genuine leather treatment, and then assembled to the door body. Among them, the disadvantages of using artificial leather (imitation leather) covering are: 1. The product has a poor touch; 2. When the product is curved and curved, the leather surface will be separated from the frame of the decorative panel due to the large tension, resulting in bulging ; 3. At the same time, the skin pattern on the surface of the imitation leather will also become shallow and blurred due to excessive elongation, and the quality of the imitat...
