Mobile Phone Card Tray MIM Parts

Product Introduction

Some time ago, when I visited the forum, I saw someone complaining on the forum. Because the card tray of the mobile phone was deformed after inserting and unplugging the mobile phone card many times, this netizen could not use the mobile phone when he was in a hurry to call the leader. Angrily smashing the mobile phone, the newly bought thousands of oceans of new mobile phones, most of the kidneys. Although the remaining rationality saved the mobile phone, in the end, this netizen was so angry that he cursed a famous international mobile phone manufacturer and its founder.

Excellent Mobile Phone Card Tray MIM Parts, must have good appearance, good connotation, and can bear hardships and stand hard work

As a tiny part inside the mobile phone, the mobile phone card tray is used to fix the SIM card and microSD card of the mobile phone. If there is no problem, it will hardly attract people's attention. However, if there is a failure, the mobile phone card cannot be inserted into the mobile phone, and the mobile phone cannot be used. , In this era when the mobile Internet is developing strongly and mobile phones have become people's conjoined pets, this is almost killing people. No wonder the above-mentioned netizens are so angry.
So what kind of mobile phone card tray is an excellent card tray that does not affect or even enhance people's mobile phone user experience?
It is said that as an excellent Cato, the first thing is to have a good appearance: its smoothness must be high, and the dimensional accuracy of the product must meet the requirements; the second is to have a good connotation: the structure is compact, and the mechanical properties such as material density and hardness must meet the standards. ; The third is to be able to bear hardships and stand hard work: the wear resistance and corrosion resistance are better, and it can withstand repeated plugging and unplugging for many times.
As a device with a weak sense of existence in people's concept, the mobile phone card tray originally has such complicated specifications and quality requirements. So here comes the question: How can we produce such a good-looking and stable and reliable mobile phone card tray?

Good materials are the genetic guarantee for the birth of excellent mobile phone card trays

When it comes to good looks, you probably have to be born with beauty, that is, you have to have good genes. The mobile phone card holder as a product is no exception. To ensure the appearance and size of the mobile phone card tray, its constituent materials are extremely important. And for any product, the correct selection of Mobile Phone Card Tray MIM Parts materials is the most important thing that is related to the product's appearance, and is higher than the demand for appearance. According to the authoritative data analysis of Zhuangzhuang Optimal, a product 60% of the cost and quality of the product have been determined at the stage of material selection, so the selection of materials has a genetic influence on the product.

As a mobile phone card holder, to be pleasing to the eye, in fact, it is more important to choose a suitable manufacturing process.
The mobile phone tray is a small, complex, precise, and high-performance metal component. For this type of component, metal injection molding (Metal Powder Injection Molding, referred to as MIM) is a very effective manufacturing process. Guangzhou Xupeng Huang said that MIM is a high-tech combination of traditional powder metallurgy technology and plastic injection molding technology. Its technical process is as follows: first select the metal powder and binder that meet the requirements of MIM, and then at a certain temperature, use an appropriate method to mix the powder and binder into a uniform injection molding feed, after granulation, inject Injection molding on the forming machine, the obtained formed blank is degreased and then sintered to densify the final product.
In short, the advantage of MIM technology lies in the ability to produce features that cannot be achieved with traditional investment casting, such as small holes, thin walls, and fine surfaces, and to produce better fineness that casting or casting cannot. Therefore, MIM technology can effectively guarantee the high density and good color of the mobile phone card tray. As early as 2010, Apple announced that it approved the use of MIM process to manufacture metal parts.
MIM technology needs to undergo degreasing, sintering, and secondary treatment processes after feed injection molding. These key processes require enterprises to have relevant technical advantages and rich processing experience.
It can be seen from this that for an excellent mobile phone card tray, strict material selection, mature technology and production technology are the key factors for its birth.
As a behind-the-scenes hero, the mobile phone card company hides its merits and fame
As a tiny part of fixing the SIM card in the mobile phone, the cell phone card tray is hardly noticed by people. Therefore, its manufacturers also exist like behind-the-scenes roles. However, it is these heroic enterprises behind the scenes as the cornerstone and the screw-like support that have led to the leapfrog development of Chinese manufacturing and the rapid advancement of the Chinese economy. These introverted companies do not have the dazzling halo of terminal product companies, and do not have the attention of thousands of pets, but they are especially worthy of our respect!
