Process for producing colour plastic dash board of bicycle

Abstract

The production process of color plastic dashboard for bicycle may include the steps of: dyeing nano polypropylene material, injection to form and riveting; or include the steps of: dyeing nano polypropylene material, extrusion to form, punching and riveting. The color plastic dashboard is superior to available metal dashboard in that it is light, varying design and color, low cost, being beneficial to environment protection, no dust, high elasticity, high toughness, impact strength and durability similar to metal ones, etc.

Description

technical field [0001] The invention relates to a preparation method of a bicycle colored plastic fender. Background technique [0002] Bicycles are a very common means of transportation, and the annual market demand in my country alone is about 90 million. Most of the existing bicycle fenders are made of metal materials, which are complicated in processing technology, consume a lot of metal materials, and have high costs. [0003] The manufacturing process of the metal fender is: metal sheet → leaking piece (consumes a lot of steel, because there is a lot of cutting material) → punching (in a special mold) → anti-corrosion (decontamination in a special liquid) → baking paint → riveting → Inspection → Packing. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to avoid the deficiencies in the prior art, and to provide a low-cost manufacturing process for bicycle colored plastic fenders without metal materials. [0005] The following technical solu...
