01 Vacuum Plating Vacuum electroplating is a physical deposition phenomenon. That is, argon is injected in a vacuum state, and the argon hits the target. The target is separated into molecules, which are absorbed by conductive goods to form a uniform and smooth metal like surface layer. Advantages: high quality, high brightness and product surface protective layer Typical applications: surface treatment of reflective coatings, consumer electronics and heat shields Applicable materials: 1. Many materials can be vacuum plated, including metal, soft and hard plastics, composite materials, ceramics and glass. Among them, aluminum is the most commonly used for electroplating surface…

Although secondary injection molding requires more complex design, processing and material selection than single injection molding, it has significant advantages: 1. It allows material combinations to provide properties that cannot be provided by a single resin. 2. It can eliminate assembly steps, saving time and money. 3. It can fuse materials in a way incomparable to the assembly process. 4. The insert increases the strength and durability of the part. Cost reduction and rapid production Cladding molding can reduce the production cost. Standard injection molding can combine multiple parts into a single multi cavity mold, and secondary molding can produce…

Cladding molding is an injection molding process that allows adding an additional layer of resin to existing molded parts to provide a combination of properties that cannot be provided by a single material. One of the most common applications is to add a layer of soft, functional, hands-on rubber like material, usually TPE (thermoplastic elastomer), to the hard substrate. The other is to change or enhance the appearance of parts or "cosmetics" by coating materials with different colors or surface treatments. Cladding molding materials can be found on everything from medical devices and hand tools to toothbrushes, as well as…

What is a quick coupler? A quick connector is a connector that allows a line to be connected or disconnected without tools. We are familiar with some water pipe quick connectors, oil pipe quick connectors, etc. As shown in the figure, you should have seen it in your life. The quick screening editor below will introduce the quick coupler in detail. In order to adapt to the differences in the demand characteristics of different devices for quick connectors, quick connector manufacturers produce many kinds of products, but it is a trouble for many consumers. The understanding of the model of…

After years of development, the hydraulic tubing in China has become very mature. Hydraulic oil pipes are mainly used for non corrosive or corrosive media such as oil, water and gas. With the increasing demand for such products in many fields, the publicity and promotion of such products are also the focus of businesses. The hydraulic pipe joint is a component in the hydraulic system that connects the high pressure oil pipe and the high pressure oil pipe. Hydraulic couplings can also be divided into hydraulic hoses, high-pressure ball valves, quick couplings, ferrule couplings, welded couplings, high-pressure hoses, transition couplings,…

The DC electric welding machine is a kind of electric welding machine that uses the high voltage arc generated when the positive and negative poles are short circuited instantaneously to melt the solder on the welding electrode, so that they can achieve the purpose of atomic combination. Now, let's get to know it together with the Speed Plus Mesh! Principle of DC welding machine: DC electric welding machine is an electric welding machine whose output power is DC power. It has the advantages of easy arc ignition, stable arc and good welding quality. DC electric welding machine can also be…

In order to reduce the vibration and noise of the hydraulic system of CNC machine tools and avoid the expansion of noise, prevention and improvement should be done in the following aspects: （1） Improvement of Hydraulic System Structure In the process of controlling the hydraulic system of CNC machine tools, attention should be paid to the use of low-noise hydraulic components. Through research, it is found that the old hydraulic pumps are mainly plunger pumps or gear pumps, and their noise vibration and noise are much higher than those of vane pumps, and their rated pressure is also very high.…

1. The universality and harmfulness of burrs Burr is an inevitable product of metal processing, which is difficult to avoid completely. The existence of burr not only affects the appearance of the product, but also affects the assembly and service performance of the product, speeds up the wear between equipment and reduces the service life. With the development of high technology and the improvement of product performance, the requirements for product quality become more and more strict, and deburring of mechanical parts becomes more and more important. The existence of burr has a great impact on product quality, product assembly,…

Machining performance is not only related to the interests of enterprises, but also related to safety. While bringing economic benefits to enterprises, it can also effectively reduce the probability of safety accidents. Therefore, it is particularly important to avoid part deformation in the process of part processing. Operators need to consider various factors and take corresponding measures to prevent deformation during processing, so that finished parts can be used normally. In order to achieve this goal, it is necessary to analyze the causes of deformation in part processing and find out reliable measures for part deformation, so as to lay…

It refers to a metal thermal processing process in which materials are heated, insulated and cooled in solid state to obtain expected structures and properties. This technology plays an extremely important role in the flat plate platform industry. In order to make metal workpieces have the required mechanical, physical and chemical properties, in addition to reasonable selection of materials and various forming processes, heat treatment process is often essential. First, the quick screening editor introduces: 1、 Surface treatment technology of mould In addition to the reasonable matching of the matrix with high strength and toughness, the surface performance of the…
