Why need to make the Finish for Metal Part Normal metal materials of iron,Aluminum,copper have active chemical properties,If they are exposed to the air for a long time, their surfaces will be oxidized or even corroded, seriously affecting the performance of materials. Therefore, in order to make these metal materials more durable and beautiful, their surfaces are usually treated to extend their service life and increase their aesthetics There some noraml finish way for the metal: Spray Paint:Spray painting is a painting technique in which a device sprays coating material through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles. Electroplating：Electroplating is a surface processing method to deposit the cations of pre plated metal on the surface of the base metal by electrolysis in a salt solution containing pre plated metal with the substrate metal as the cathode. The coating performance is different from that of the base metal and has new characteristics. According to the function of the coating, it can be divided into protective coating, decorative coating and other functional coatings. Electrophoresis：Electrophoresis refers to the process in which the charged coating ions move to the cathode under the action of voltage applied at the cathode and anode, and react with the alkalinity generated on the cathode surface to form insoluble matters, which are deposited on the workpiece surface. Galvanization:Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials for aesthetic, rust prevention, etc Blacken:The surface blackening treatment of steel parts is also called bluing. The principle is to rapidly oxidize the surface of steel products to form a dense oxide film protective layer, so as to improve the anti rust ability of steel products. Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing. Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon.

  HOW DOES ULTRASONIC WELDING WORK? Ultrasonic welding is a welding process that uses high-frequency ultrasonic as a heat source and pressure source to obtain instantaneous high temperature and pressure on the surface of the workpiece, so as to soften, melt and fuse the workpiece materials. The working principle of Ultrasonic welding is: during welding, the power source converts the electric energy into ultrasonic energy, and transmits the ultrasonic wave to the workpiece surface through the welding joint, so that the contact between the two workpieces is heated by friction, and dense fusion is carried out under a certain pressure to form a solid welding joint.Ultrasonic welding equipment is usually composed of generator, transducer, welding joint, workpiece and control system. Among them, the generator is the core component that converts electrical energy into ultrasonic energy. The transducer converts the electrical energy of the generator into mechanical vibration, and the welding head transmits the mechanical vibration to the surface of the workpiece through contact for friction heating and pressure dense fusion. The entire process is automatically controlled by the control system. Ultrasonic welding has the advantages of fast welding speed, simple operation, high welding joint strength, environmental friendliness, etc. It is widely used in many industries such as automobile, electronics, pharmacy, medical treatment, food, chemical industry, etc.   THE ADVANTAGES OF ULTRASONIC WELDING + Very short process times+ Little or no thermal damage to the component due to cold welding tools+ Low energy requirement for welding and thus high efficiency+ No solvents and additives necessary (pure recycling)+ Constant, reproducible welding results are possible via a wide range of welding parameters+ Different thermoplastic materials can be welded together+ The welding tools do not heat up, so there are no warm-up and cool-down times and the tools can be changed quickly+ No risk of injury from hot machine parts+ Very good integrability into existing systems+ Possibility of intelligent networking and self-control    Analysis of Thermoplastic  Material in Ultrasonic Welding   ABS ABS+PC PE PP PS PMMA NYLON PC ABS Good Good           limited ABS+PC Good Good           limited PE     Good           PP       Good         PS         Good       PMMA           Good     NYLON             Good   PC limited limited       limited   Good                   Applications 1.Automobile manufacturing industry: Ultrasonic welding can be used for welding many components in automobile manufacturing industry,Such as instrument panel, seat,lamp,etc 2.Medical device Manufacturing: Ultrasonic welding can be used in medical device manufacturing,such as the sealing of medicine bottles and infusion bottles, mask. 3.Electronic manufacturing industry: Ultrasonic welding can be used to manufacture circuit boards,assembly of electronic equipment and connections on connecting wires 4.Packaging industry: Ultrasonic welding canb e used as packaging matterials in food and pharmaceutical industries. 5.Pipeline manufacturing:Ultrasonic welding can be used to manufacture plastic pipes and metal pipes 6.Textile industry: Ultrasonic welding can be used for sewing and corner treatment of textile materials 7.Air conditioning manufacturing industry: Ultrasonic welding can be used for welding metal elements in air conditioning manufacturing 8.Air purifier manufacturing industry: Ultrasonic welding can be used for the welding of filters in air purifiers FAQS How to make the Ultrasonic welding set ?

  What's the Plastic Spray Painting    Plastic spray painting is a surface treatment method of spraying paint or film on the surface of plastic products. It uses a spray gun or spraying equipment to evenly spray paint on the surface of plastic products, forming a layer of paint film, achieving the goal of aesthetics, protection, and improvement of plastic surface performance.    Plastic spray painting can improve the appearance quality of plastic products, provide personalized color and effect choices, and increase the durability and protection of plastic surfaces. When selecting painting materials and processes, attention should be paid to factors such as compatibility with plastic materials, adhesion, and chemical resistance to ensure that the painting effect meets the requirements. In addition, reasonable painting operations and environmental control are also crucial for the final painting effect.   How to work of Plastic Spray Painting Basic Treatment:Clean and treat the plastic surface, including removing oil, dust, and other impurities. This can be achieved through cleaning agents, solvents, or mechanical methods such as sanding. Primer coating: Spray primer on plastic surfaces. Primer can enhance adhesion, fill small holes and uneven surfaces, and provide a good color foundation.                                                                                                                                    Sanding treatment: Sanding treatment is applied to the plastic surface after the primer has dried to remove surface irregularities and prepare the coating surface.                                                                        Top coat coating: Spraying topcoat, its color and appearance will directly affect the final appearance of plastic products. The topcoat usually includes a variety of color and effect options, such as matte, bright, metallic texture, etc. Drying and Curing: The paint film needs to be dried and cured at a suitable temperature to ensure complete formation and good durability.                                                                                                                What's the Advantage of Plastic Spray Painting Aesthetics and decoration: Spray painting can provide rich colors and surface effects for plastic products, giving them a better appearance and decoration effect. Spray painting can make plastic products appear smoother and more uniform, increasing the overall beauty and attractiveness of the product.   Occlusion defects: Plastic products may have some defects, traces, bubbles, and other defects during injection molding or other processing processes. By spraying paint, these defects can be obscured or reduced in visibility, improving the appearance quality of plastic products.   Surface protection: Painting can provide a protective layer for plastic products to prevent erosion and damage from the external environment. Plastics themselves often have a certain sensitivity to ultraviolet radiation, chemicals, etc. By applying a paint layer, damage to the surface of plastics can be reduced and their color, appearance, and performance can be protected.   Increase wear and corrosion resistance: Proper spray painting can increase the wear and corrosion resistance of plastic products, extending their service life. Special coating technology can enhance the durability of plastic products by endowing plastic surfaces with characteristics such as scratch resistance and chemical resistance.
