This paper analyzes the role of surface treatment processes in design implementation, starting from the relationship between surface treatment processes and products. Taking the faucet as an example, the common materials of faucets and the application of surface treatment process are explained
Faucets are used in a humid environment, and their surfaces require good gloss. Now on the market faucet surface treatment mainly are electroplating: make metal or alloy deposited on the surface of the workpiece by electrolysis, in order to form a uniform, dense, well-bonded metal layer process, divided into chrome plating, nickel plating, titanium gold plating, etc.. In addition, there are some baking paint, baking porcelain, electrophoretic paint and other ways. After the faucet grinding and polishing molding, according to the design requirements for the relevant surface treatment, and then the faucet should be salt spray test, to determine its salt spray test can reach the national standards.
Here is the general surface treatment of Lanerdi:
Below is the non-general surface treatment of Lanerdi, need to reach a certain number to make :
Polishing of stainless steel faucet metal parts refers to the processing method that uses the machinery to reduce the surface roughness of the workpiece to obtain a bright, flat surface, mainly refers to mirror polishing.
Polishing process: ultrasonic cleaning - abrasive belt polishing - sisal wheel polishing - cloth wheel polishing - ultrasonic cleaning.
Through the grit of the abrasive belt, the rough (i.e., large grit) passes to remove defects within the metal surface such as pits, indentations, lines and scratches. Finer abrasives will gradually leave fine lines that are not visible to the naked eye.
Can achieve the surface effect of plating.
1.the stainless steel molding material requirements are extremely high.
2.the surface hardness is not high, easy to scratching surface
Sand blasting is also known as abrasive blasting, which is a process that uses compressed air as power to force solid particles across surface at high speed to smooth, shape and clean hard surfaces, causing a change in the surface or shape of the workpiece to obtain a certain level of cleanliness and varying roughness.
The effect is similar to using sandpaper, but provides a more uniform finish with no problems in corners or crevices
1.For non-appearance parts: cleaning - sandblasting.
2.For Appearance parts: cleaning - abrasive belt polishing – sandblasting - cleaning.
1. To achieve different reflective or matte effects.
2. Can clean the tiny burrs on the surface of the workpiece, and make the surface more flat, eliminating the harm of burrs and improving the grade of the workpiece.
3. Improve the finish of the workpiece, and can make the workpiece reveal a uniform and consistent metal original color, making the appearance of the workpiece more beautiful
Chrome is a silvery-white metal with slightly blue lustrous. Chrome plating has high hardness and wear resistance. Chrome plating heat resistance is good, below 500 degrees its hardness and color are not obvious changes. Chrome plating on the surface of polished faucets can be obtained with a slightly silvery-blue coating with a mirror-like luster. Chrome has a strong passivation ability, will generate a very thin passivation film in the surface of the parts, and does not change in the humid air, can maintain its glossy appearance for a long time, showing a similar appearance of precious metals, have good decorative properties. Therefore, the chrome plating process is very common in the faucet. The chrome layer has good gloss, high hardness, good wear resistance, strong reflective ability, very stable in the atmosphere, can maintain its luster and stable for a long time, even in corrosive medium such as salt, nitric acid, sulfide, carbonate and organic acids.
Chrome plating a component typically includes these stages:
Degreasing to remove heavy soiling
Manual cleaning to remove all residual traces of dirt and surface impurities
Various pretreatments depending on the substrate
Placement into the chrome plating vat, where it is allowed to warm to solution temperature
Application of plating current for the required time to attain the desired thickness
Brushed is a surface treatment means to form a line pattern on the surface of the workpiece by grinding the product to play a decorative effect.
According to the different patterns after wire drawing can be divided into: straight brushed, ripple, spiricle, etc.
ultrasonic cleaning, abrasive belt polishing, nylon wheel brushed, ultrasonic cleaning.
brushing treatment can make the metal surface get non-mirror-like metallic luster, while the brushing treatment can also eliminate the subtle defects on the metal surface
Electroplating is the process of using electrolytic principle to coat the surface of certain metals with thin layers of other metals or alloys. The process of using electrolysis to attach a metal film to the surface of metals or other materials, thus preventing metal oxidation (such as rust), improving wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.
Process: abrasive belt polishing, hemp soft cloth wheel polishing, degreasing, washing, pre-cleaning, (acid copper solution), nickel plating, decorative layer (chrome, gold, etc.), washing, drying.
1. High gloss of plating, high quality metal appearance; improve the hardness of stainless steel products.
2. Low price compared to PVD.
Poor environmental protection, higher risk of environmental pollution
Knowledge and understanding of the surface treatment process occupies a very important position in product design. The designer's mastery of the surface treatment process is a means of completing the design and is a service to the design, and a suitable surface treatment can make the product's layers full and enrich the product's shape. Surface treatment is to a certain extent the communication and coordination work between the subject groups of material expressiveness to ensure that the promotion of scientific research results is carried out efficiently
