What are the main aspects of the good quality of color coated rolls

When using color coated rolls, we usually hope that the quality and price of the products we buy are very suitable and cost-effective products. For manufacturers, in order to be able to produce good quality products, it is necessary to grasp more relevant information, so as to be able to pay attention to more details when processing, so that the quality of the color coating roll can be improved, so it is necessary to understand several aspects of the quality of the color coating roll.

First, mechanical properties and related indicators

When processing color-coated products, mechanical properties need to be used as an important indicator to measure the formability of the product, so you can check this aspect first when processing and purchasing. At the same time, the pencil hardness, T-bend, impact power and other indicators of the color coating roll are closely related to the processing performance, so they should be fully considered.

Second, processing technology

Because of the complex shape and large deformation degree of a wide variety of color coated parts, it is necessary to adopt multi-pass forming in the processing technology. If the direct one-time forming, may destroy the coating and substrate bonding force due to excessive deformation, so the processing of color coating roll should be based on the mold shape, deformation characteristics, process conditions and other factors to set the appropriate gap, gap setting should consider the thickness of the coating.

Third, lubrication performance

The coating of most color rolls can be used as a solid lubricant, and can meet the lubrication requirements of most forming processes, and some coatings can be adjusted to improve the lubricity of the coating. If the lubricity of the color coated coil coating is insufficient, the lubricity can be improved by applying oil, waxing, covering the peel protective film, etc., so that a better quality product can be produced.

These are the main aspects of good quality color coating rolls. In addition, it should be noted that wet lubricants are easy to absorb dirt and should be removed before installation. The peeling protective film in the process of use should also be removed as soon as possible after the completion of the construction, and for the buyer, you can also judge the quality of the product through these professional knowledge, so as to buy the product to make yourself satisfied.
