Tablet PC MIM Parts

Product Introduction

Application field
From the perspective of the metal powder injection molding industry chain, the upstream industry mainly provides product raw materials, including metal powder, binder, etc. Metal powder and binder need to be mixed to generate feed, so as to be used as direct raw materials for MIM parts. Sintering is a one-step process in the process of MIM parts, which sinters the pores between powder particles. Make the MIM parts products achieve full densification or close to full densification. With the gradual maturity of MIM parts technology, the application field is gradually expanded, and its technology is also gradually applied to automobile manufacturing, medical equipment, hardware tools and other industries. With the improvement of residents' living standards, the demand for electronic products increases, and the technological advantages of MIM parts such as high complexity, high precision, high strength, and exquisite appearance increase the attraction of automobile manufacturing, medical equipment and other fields. The continued development of the MIM parts industry produces a huge boost. , pressure limiting valve, oil gauge, pressure-sensing plug and dipstick etc. Fuel system: The gasoline engine fuel system is composed of gasoline tank, gasoline gauge, gasoline pipe, gasoline filter, gasoline pump, fuel injector, air filter, intake and exhaust manifold, etc. Ignition system: It is composed of ignition power supply, ignition switch, ignition coil, spark plug and high-voltage wire.

• Consumer electronics field
Powder metallurgy is an advanced metal forming technology. It is a high-tech technology in which metal and other powders are processed into mechanical parts and metal products through processing, pressing, sintering and necessary subsequent treatment. Traditional consumer electronics products usually include hardware devices such as smart phones, tablet computers, laptops, digital cameras, etc. Emerging consumer electronics devices include smart wearable devices, drones, etc. In 2010, the appearance of the signage of the BlackBerry mobile phone adopted MIM parts manufacturing technology, which opened the mass use of MIM parts on mobile phones. Tablet PC MIM Parts; How to use a single part of a MIM part product. Predict forming defects, optimize stamping process and mold structure, improve the reliability of mold design, and reduce the time of mold trial. Many domestic automobile mold companies have also made significant progress in the application of CAE and achieved good results. The application of CAE technology can greatly save the cost of mold testing and shorten the development cycle of stamping molds. Automobile molds have become an important means to ensure the quality of molds. CAE technology is gradually changing mold design from empirical design to scientific design
In recent years, smartphones around the world have gradually shifted from a single camera to two or more cameras. With the increase in the number of cameras, the internal structure of the module is more dense and complex, and the advantages of the MIM component camera bracket are more obvious, such as higher economy and higher product size accuracy.
With the increasing maturity of MIM parts technology and the strong demonstration and driving effect of brand enterprises' continuous innovation, optimization and upgrading of products, the penetration rate of MIM parts technology multi-camera brackets will be rapidly improved, and the future demand will grow rapidly. MIM parts shaft Supporting the folding function is expected to grow with the increase in the volume of folding screen mobile phones.

• Automobile manufacturing field
In the field of auto parts manufacturing, as a non-cutting metal parts forming process, MIM parts technology can save a lot of materials, reduce production costs, and even reduce the weight of parts, which is conducive to the lightweight of automobiles and reduce environmental pollution. The automotive industry attaches great importance to it. At present, the automotive industry has adopted some complex shapes, bimetallic parts and groups of micro-small parts produced by MIM parts technology, such as turbocharger parts, adjustment rings, fuel injector parts, vanes, gearboxes, power steering parts, etc.

• Medical device field
In the field of medical devices, the medical accessories produced by the MIM parts process have high precision, which can meet the requirements of small size, high complexity, and high mechanical properties required by most precision medical devices for accessories. In recent years, MIM parts technology has been more and more widely used, such as scalpel handles, scissors, tweezers, dental parts, orthopedic joint parts, etc.
How to use the mold in the powder metallurgy process, the selection of the mold is very important, because it is a very important point in the production process. Powder metallurgy is a process technology for producing metal powder or using metal powder as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products.
Therefore, during manufacturing, the material powder is first filled between the molds, and then compacted and heated through the molds to obtain the finished product.
Compared with other processes of powder metallurgy parts, in the case of mass production, the advantage of cost saving is very obvious, and the rational use of molds in its production process is also an important measure to reflect the economy.
The shapes that are easy to make by powder metallurgy process are those with the same size in the pressing direction, gears, and those with concave and convex shapes all belong to this category.
For parts with through holes in the pressing direction, the holes are formed with a mandrel. In general, it is economical to make round holes because they can be formed with the same mandrel. However, to make holes of other shapes, the cost of making the mold must be increased.
When forming multi-table powder metallurgy parts with a mold, each table of the part must be pressed and formed separately by independent upper and lower die punches.
In order to make the density of multi-table parts uniform everywhere, the number of pressing actions of the mold punch should be equal to the number of parts forming tables. If the mold is complicated or the production cost is expensive, in order to reduce the mold manufacturing cost and avoid problems that affect the quality of the formed parts, it can be reduced. The number of directly formed parts tables, the remaining tables can be machined on the formed/sintered parts by machining.
If the length of the groove on the top or bottom surface is not greater than 1/4 of the length of the part, it can be directly pressed and formed, and it does not need to be pressed and formed in a separate mold.
If the boss height of the end surface and the bottom surface of the part is not greater than 15% of the total length of the part, it can be directly pressed and formed without using a separate die for stamping and forming.
