Problems solved by technology

[0003] Due to the light transmission requirements of the lamp cover, generally use transparent materials for single-color injection molding, or multi-color injection molding of black and transparent materials, and then spray transparent hardened paint on the outer surface; therefore, the color of the finished lamp cover is the color of the injection molding material itself. When the customer has special requirements for the color of the lamp mask, the existing lamp mask production process cannot be realized

Embodiment

[0031] Embodiment: Step 1: First, use PC or PC+diffusion agent material to inject the light-transmitting part in the mold. After the light-transmitting part is formed, then use ABS or PC+ABS to inject the opaque part to complete the molding of the mask body. During the process: drying material temperature: 110℃~120℃.

[0032] Baking time: 3 to 4 hours.

[0033] Moisture content: ≤0.02%.

[0034] Mold temperature: 100-120°C.

[0035] Melting temperature: 270℃~330℃.

[0036] Injection pressure: 80MPA ~ 150MPA.

[0037] For the treatment of PC+ABS materials: Baking material temperature: 100℃~105℃.

[0038] Baking time: 3 to 4 hours.

[0039] Moisture content: ≤0.02%.

[0040] Mold temperature: 70-90°C.

[0041] Melting temperature: 230℃~270℃.

[0042] For the treatment of ABS materials: baking material temperature: 85 ℃ ~ 95 ℃.

[0043] Baking time: 3 to 4 hours.

[0044] Moisture content: ≤0.02%.

[0045] Mold temperature: 70-90°C.

[0046] Melting temperature: 220℃~...

Abstract

The invention belongs to the technical field of car lamp mask production processes, and particularly relates to a production process of a multicolor exterior lamp mask. The production process of the multicolor exterior lamp mask is characterized by comprising the following steps: 1, forming a mask body through injection molding; 2, spraying colored paint to the mask body; 3, removing the colored paint of the portion needing to be pervious to light in a laser etching mode; and 4, spraying transparent paint to the mask body subjected to laser etching treatment.

Description

technical field [0001] The invention belongs to the technical field of production technology of car lamp masks, and in particular relates to a production technology of multi-color exterior lamp masks. Background technique [0002] The usual production process for the existing exterior lamp masks is as follows: 1) forming the mask body through single-color or multi-color injection molding, 2) spraying hardened paint on the mask body to realize the protection of the lamp mask. [0003] Due to the light transmission requirements of the lamp cover, generally use transparent materials for single-color injection molding, or multi-color injection molding of black and transparent materials, and then spray transparent hardened paint on the outer surface; therefore, the color of the finished lamp cover is the color of the injection molding material itself. When the customer has special requirements for the color of the lamp mask, the existing lamp mask production process cannot be rea...
