Abstract

The invention belongs to the technical field of motorcycle reflectors, and particularly relates to a primer-free aluminum plating process for a motorcycle LED reflector. Aiming at the problem that themanufacturing process is too complex in the prior art, the invention provides the primer-free aluminizing process for the motorcycle LED reflector. The process comprises the following steps: 1, melting and stirring reflector raw materials until the reflector raw materials are uniformly mixed; 2, injecting the uniformly mixed molten raw materials into a forming mold by using an injection molding machine, maintaining the pressure, opening the mold, ejecting, naturally cooling, polishing by using a milling machine, and immersing into a cyclohexanone solution for 5-10 minutes to obtain a semi-finished product; and 3, assembling a heat dissipation assembly on the semi-finished product obtained in step 2 to obtain a reflector finished product. By improving the raw material composition of the reflector, the reflectivity of the product is guaranteed, meanwhile, primer coating is not needed, the sprayed paint photocuring process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of motorcycle reflectors, and in particular relates to a bottomless aluminum coating process for motorcycle LED reflectors. Background technique [0002] With the popularization of motorcycle LED lighting, in order to achieve more beautiful and more personalized lighting effects, LED lighting is often costly. How to control costs and improve product competitiveness has become the top priority of various companies. The common manufacturing processes of existing motorcycle light reflectors are mostly used: 1. Injection molding, 2. Spraying light curing, 3. Aluminum plating; the three processes are indispensable, resulting in too complicated processes, and a relatively simple manufacturing process is urgently needed craft. [0003] For example, a Chinese invention patent application discloses a manufacturing process for car lamp reflectors [application number: 201410423427.2]. For resin slurry, the filler in ...
