Notranjost avtomobila je sestavljena iz več glavnih delov, kot so glavna armaturna plošča, podčlanska plošča, stražarji na notranjih vratih, stebrički, headliner, preproge, sedeži itd. Ne priporočamo za varčevanje z energijo in zmanjšanje emisij . Drugi primer je, da bodo leseni materiali povečali stroške proizvodnje avtomobila, kar ne bo pripomoglo k poznejši prodaji na trgu . Plastični material je lahko dobra rešitev za to težavo, ne samo da lahko zmanjšajo težo, ampak tudi zmanjšajo stroške, ampak tudi zmanjšajo stroške .
Sklopi nadzorne plošče je mogoče razvrstiti v trde armature in mehke armaturne plošče glede na njihovo teksturo površine .
Rigid instrument panels are plastic instrument panels that are molded directly by injection molding process, and the materials used are PP and TOP materials. This type of instrument panel has a special texture on the surface, which requires high quality of appearance. Injection molded instrument panels are simple and low-cost, and are generally used in low-end passenger cars, buses and trucks. Soft instrument Plošče so mehke na dotik, kar omogoča ljudem, da sedijo v kabini v udobnem in prijetnem vzdušju, večinoma se uporabljajo v avtomobilih višjega cenovnega razreda .
Soft instrument panel is generally composed of injection molded skeleton and foam surface layer, with the function of collision energy absorption. Skeleton is mainly made of PC/ABS, PPE, PP + EPDM + T20 injection molding, the use of these materials can not only reduce the cost of car manufacturing, and injection molding out of the product performance is excellent. The foam layer je na splošno izdelan iz PU materiala, ki se imenuje tudi poliuretan, kožo in okostje pa lahko dobro poveže, zmanjša hrup in vibracije ter izboljša videz in teksturo instrumentne plošče kot celota .
The skin material is usually made of PVC powder through the plastic lining process, so it is also known as plastic lined skin in the industry. PVC material has many advantages, first of all, the cost is not high, so the manufacturer can use the lowest cost to get the best performance, in order to seek the most profit. Secondly, the product is easy to color and smooth in appearance, which greatly enhances the feel of the product. Finally, it is durable and wear-resistant, which prolongs the service life of the product. The whole process of skin lining refers to the rotation of the lining mold, so that the PVC material in the centrifugal force and heat, uniformly coated, fused, adherent and mold cavity of the entire surface of the molding, and finally cooled and Oblikovana . emajlirana koža, ostri robovi, jasna tekstura, dotik je enakovredna pridihu usnja, vendar ne tako drag kot usnje, tako ljubijo potrošniki .
