Embodiment 1

[0050] Embodiment 1 provides a kind of such as figure 1 For the shown plastic trim, the molding process of the plastic trim includes:

[0051] (1) Sheet production

[0052] The planar sheet provided in Example 1 is made from mold A, including a carrier layer and a decorative layer.

[0053] The raw material of the carrier layer is acrylonitrile-butadiene-styrene copolymer.

[0054] The curing temperature of the mold A is 220°C.

[0055] The thickness of the carrier layer is 0.18mm.

[0056] The thickness of the decoration layer is 20 μm.

[0057] After the sheet is made, the PET protective film on the surface is torn off by transferring the sheet.

[0058] (2) Sheet forming

[0059] The sheet molding refers to molding the sheet obtained in step (1) through mold B.

[0060] The mold B has a temperature adjustment function. Before the sheet produced in step (1) enters the mold B, the temperature of the mold B is raised to 220°C, which is consistent with the temperature of...

Embodiment 2

[0065] Example 2 is a commercially available sheet with a thickness of 0.2 mm.

Abstract

The invention relates to the technical field of plastic molding, in particular to an efficient molding process of a high-strength plastic decorative part. The energy-saving and environment-friendly molding process of the plastic decorative piece at least comprises the following process that (1) sheet manufacturing, specifically, a die A is used for manufacturing a sheet; and (2) sheet molding, specifically, a die B is used for the molding of the sheet. The thickness of the sheet prepared by the molding process of the plastic decorative part is adjustable, operator do not need to manually participate in the transfer printing process of the decorative part, the instantaneous high-temperature energy consumption of a die cutting device is reduced, the energy is saved and the environment is protected, meanwhile, the use amount of the sheet is greatly saved, the production efficiency of transfer printing of a decorative shell is improved, the labor intensity of operators is reduced, the production cost is reduced, the uncertainty caused by manual operation of the operators and uneven temperature of membrane is avoided, and the transfer printing quality of the decorative part is improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of plastic decorative parts, in particular to an energy-saving and environment-friendly molding process for plastic decorative parts. Background technique [0002] The molding process of general plastic decorative parts includes: flat printing-molding (die-cutting)-injection molding-molding. In order to pursue the beauty of parts, the decoration requirements are constantly increasing, and it is necessary to transfer various patterns on decorative parts. In the prior art, thermal transfer printing technology is well developed and mostly used in full-area decoration. The comprehensive application of insert injection molding and film interior decoration technology can not only reduce the production cost, but also improve the transfer effect to a certain extent. However, in the actual manufacturing process, operators complete multiple inter-process operations, resulting in low product...
