The largest export volume of consumer MIM products
In 2018, 3C consumer electronics demand remains the most important segment of MIM industry in mainland China.The application of dual-camera, three-camera and other multi-camera camera supports in mobile phones has promoted the demand for MIM materials and processing in the industry.And vivo similar lifting camera several parts using MIM parts, promoting the development of small size, precision parts processing technology, in addition to e-cigarette is gradually expanding to MIM processing.So which of the many consumer electronics products is the most shipped MIM product?
From 2014 to 2016, the smart phone metal cator once led the trend, with a shipment of more than 150 million.By 2018, while the double, three perturbation, and so on intake much taken camera phones popular in the market, depend on these phones of MIM lens group also has a lot of, but really is the biggest still occupy the MIM shipments of apple – Lightning quick charge cable Connector (from the Connector) terminal head stainless steel shell, is referred to as the 3 c product in the history of the most successful MIM parts, even apple’s own all surprised.It is reported that the lightning connector stainless steel shell does not contain the number of shanzhai products, more than 1 billion have been shipped (from 2012 to the end of 2018), and even consumers to buy the shanzhai products will be specified to use the MIM technology, because other processes made lightning connector iron shell is not as durable as the MIM stainless steel.Dr. Q qiu just came into contact with this product in his previous work. The three MIM factories shipped as many as 6 million pieces per day, which could not be stopped for six consecutive months. The peak demand injected vitality into China’s MIM industry, and even now at least 5 million pieces are shipped every week.And the highest record of MIM product should be a bird shot in the United States. The MIM product is shipped more than 1 billion times a year, so we are referring to consumer electronics products in particular.
Why is the lightning connector stainless steel case the most shipped MIM product?
Generally speaking, every mobile phone used by consumers will use several data cables in its life, so that consumers can charge or transmit data in different places.The lightning connector has been used since iPhone 5. The new data cable has greatly changed the cable connector at the phone end. The plug is smaller and can be inserted into the phone interface regardless of the front and back.As the standard part of the current iphone, it will not change with the upgrade of the iphone if the I/O interface parts remain unchanged.
As a benchmark enterprise in the global consumer electronics industry, apple’s update of data cable is not only a vast market for domestic iPhone data cable manufacturers, but also a considerable technical challenge.One of the most important is to use MIM technology to produce stainless steel iron shell, selection of materials is a famous precipitation hardening stainless steel (PH) 17-4, according to Dr. Qq, because of the precipitation hardening stainless steel, high hardness and wear resistance properties, compared with the metal shell on the market 304 or 316 stainless steel (traditional), die-casting zinc alloy is much durable, this is apple material design engineer match point, because have to use the MIM production complex 3 d shape, lightning joint made of a variety of goods to help the apple company earn money easily, joint also led to the stronghold of counterfeit upgrade,Combined with word of mouth, the MIM product is a win.
Apple data cable brands are Lightning to USB data cable originally manufactured by apple, as well as iPhone data cables of many brands such as belkin, xiaomi, lvlian, iWALK and ROCK which have been certified by MFi.Both E75 and C48 are MFi hardware schemes. Most of apple’s original factories use the E75 scheme, while C48 is mostly the scheme of authorized MFi chips.Both schemes are MFi – certified chip schemes.
The help of MIM technology to a large number of products
The terminal of the lightning connector data line has extremely strict requirements on the size of all the mechanism parts. The manufacturer tries to adopt MIM integrated injection molding which has the advantages of precision parts processing.The 17-4ph material with fine particle size (D50=10~12 microns) is selected and processed through mixing feeding, precision injection molding, degreasing sintering, CNC, polishing and a series of processing.After heat treatment, the mechanical properties of 17-4ph are stronger, and the corrosion resistance is better.In order to enhance contact transmission, the surface of the product is also plated with nickel and gold plating.Finally, the product can go through tens of thousands of plug and pull aging tests to ensure the joint is stable and durable and avoid bad contact.
MIM processing, as a near-net molding process, is environmentally friendly and has high material utilization. The stainless steel shell of the data line terminal of the lightning connector makes another great achievement in MIM technology of precision parts.Apple’s original MFi connector C48 (C48A, C48B, C48C) may be officially discontinued on July 31, 2019, to be replaced by C89 and C94.Among them, C89 is usb-a to Lightning cable connector, and C94 is usb-c to Lightning cable connector.
Is the next generation still the MIM?
, according to Dr. Q, even to change the Type C interface, apple still insist on the MIM technology to make its mother tongue, its technical content and complexity is more high, can confirm the MIM technology is inseparable with the apple, don’t forget to still have more mobile phone parts by MIM products, even at the end of domestic mobile phone in new telescopic camera cleverly evade apple bang’s patent, will also be the MIM technology into the tiny change gear box, believe 2019 will be a good chance the MIM products a year.
If you want to enter the MIM industry and produce MIM products by yourself, what is the entire production line like?
Technical introduction of MIM:
Metal Powder Injection Molding (MIM)
It is a new powder metallurgy near-net forming technology by introducing modern plastic injection forming technology into the field of powder metallurgy.
Advantages of MIM technology: compared with the traditional process, it has the features of high precision, even organization, excellent performance and low production cost
Application of MIM technology: electronic information engineering, biological medical equipment, office equipment, automobile, machinery, hardware, sports equipment, watch and clock industry, weapons, aerospace and other industrial fields.
The most important parts of the MIM production line are feeding, injection machines, and the selection of degreasing and vacuum sintering furnaces.
SIMUWU catalytic degreasing furnace USES nitric acid or oxalic acid to remove POM by the degreasing method of nitrogen atmosphere charging and washing, which is safe and reliable. Compared with solvent degreasing, it has the advantages of larger yield and smaller performance.
The following are the degreasing furnace specifications of different specifications:
The following are the degreasing furnace specifications of different specifications:
In addition, the SIMUWU vacuum sintering furnace has nitrogen, argon and hydrogen gas in different atmospheres, which can be customized according to different processes.
The use temperature of MIM sintering generally does not exceed 1300℃, and the equipment with the highest temperature of 1400℃ can be designed.Or customize SIMUWU standard rvs-m series vacuum degreasing sintering furnace.
