Specification for leather pattern of automobile parts plastic mold
1. Conceptual elements of skin texture
Dermatoglyphic lines refer to the natural lines on the skin of living things, usually the natural lines on the skin of human beings or other animals, such as cattle, deer, crocodiles, etc.It can also refer to the texture on the surface of plants such as tree epidermis, cross section, leaves, etc.With the expansion of modern design concept, it has developed to other natural or artificial surface texture, such as stone grain, fabric grain, electric spark grain and so on.
"Leather grain" in this paper refers to the decoration on the surface of plastic products.Plastic product because material is different, the arrangement of the surface, organization, construction is different, produce consequently coarse, smooth, soft and hard feeling, expression is leather grain is different.
1.1 skin texture can be divided into the following three aspects according to style:
The shape of the fingerprint path unit can be described in geometric or pictographic form.The common forms are linear, block, line block combination and litchi shape, etc., as shown in figure 1.The shape, direction, arrangement and combination direction of the grain elements and the density of the grain elements all have important influence on the macro style of the grain.

As shown in figure 2, it can be seen that the veins of this kind of skin grain have an obvious direction.Some regular unit features are not directional, as shown in figure 3.Car leather has less directional texture.
The patterns on the leather are basically three-dimensional leather grain, three-dimensional leather grain has layers, in the micro performance of leather grain in depth direction by 2 ~ 5 different depth of the layer of the value;On macroscopical expression the grain face that is leather surface is full and fruity, administrative levels are rich rise and fall, characteristic transition is natural, the visual impact that gives a person is relatively downy, can look at administrative levels with the help of magnifying glass of 50 times.The following picture shows a typical multilayer skin pattern.

1.2 skin texture can be divided into the following three types according to size:
Is the real world has leather grain simulation evolution, texture close to the real texture, more delicate, with a sense of hierarchy, can improve the grade of the vehicle interior, general texture depth between 80 ~ 150um.Coarse leather grain is generally used as the main leather grain of automobile interior decoration, which has a strong sense of overall coordination and requires integrated design consideration of the whole vehicle interior decoration.
It is a kind of delicate and delicate texture, similar to the state of sand and stone surface, and there are many processing techniques, mainly fire pattern, sandblasting grain, etc., fine leather grain is generally single layer leather grain, texture depth between 0 ~ 80um.Fine skin grain can be decorated locally alone also can undertake collocation with a variety of other grain.

Geometric rules of texture, in the car mainly reflects the concept of technology, power, trend, general texture depth between 80 ~ 150um.Geometry grain has extremely strong directional sex and regular sex, large area USES can raise its processing difficulty greatly, the price is higher also.
