Can wearable devices replace cell phones?

We witnessed the glory of Nokia, witnessed the emergence of the iPhone, saw the blossoming of the Google rule, also experienced the three countries between ios, android, windows phone fight. After the background of the big era, the face of the current smartphone market calm and slowdown in our view seems a bit tasteless. Perhaps for now the cell phone innovation has entered a bottleneck, but we still need to have more expectations for the future. 　　Lei Jun is embarrassed 　　In late May at the Shenzhen Universiade Center stadium, Xiaomi released the crystallization since its 8th anniversary. 　　When Lei Jun went on stage and discreetly released the actual picture of Xiaomi 8, the originally noisy venue began to become quiet, the moment the PPT on the screen turned from the back of the body to the front, similar to the previous cheers and applause did not appear, you can see that the hands of the rice fans on the stage were raised slowly put down, the smile hanging on the face also gradually disappeared. 　　Yes, after 9 months, Xiaomi released an "iPhone X" with MIUI on its 8th anniversary. 　　Lei Jun also noticed the change in the atmosphere of the venue, he smiled awkwardly and explained, "I know many people say the bangs screen is ugly, but Xiaomi has added a lot of features on it, in addition to Xiaomi's bangs screen can also be turned off, so that the top shows as a complete bar." 　　Lei Jun also said that the bangs screen is not so ugly after seeing more. 　　I don't know when it started, copying Apple has become a practice within the cell phone industry. 　　Since March this year, Vivo released the first domestic bangs screen x21, followed by the appearance of Huawei's P20, OPPO r15, a plus 6 and Xiaomi 8 ...... 　　Even in this "Apple" trend, Redmi, Vivo, Lenovo and other manufacturers even pulled the bangs screen to the price of a thousand yuan machine, respectively launched the Redmi 6, z1 and z5. 　　Under the gradual convergence of ID design, from now on, domestic cell phones have truly abandoned the separation of brand and price point to achieve a harmonious and harmonious grand unification, at least in terms of appearance. 　　Even the so-called "revolutionary product" nut R1, using the "beauty tip" shaped design does not mean innovation. Mr. Luo also shouted before the release of the "lost soul of Apple crazy copy", for him instead of copying Apple, it is better to copy the father of Android Essential Phone. 　　The similarity in appearance is only the second, in the phone internal components and functional UI, the domestic manufacturers are gradually converging. 　　A person who has been studying the cell phone industry since 2003 told Pinto that since the release of iPhone 4 in 2010, it feels like the industry has "died". 　　"From the outside, there are only iPhone and iPhone Like; from the experience, what performance Qualcomm can give, what Sensor Sony can give, and what lens Sunwoo Optical can make, determine what products we can make, and this feeling is very boring." 　　In a live broadcast not long ago, Mr. Luo also confessed that the so-called "black technology" promoted by major manufacturers is almost all suppliers, manufacturers are program integrators. The application of technology depends entirely on the product positioning and cost of selling price of such a comprehensive consideration of business practices. 　　At this year's Mobile World Congress (MWC) in Barcelona, where hundreds of technology companies showed off their latest and greatest products, Ben Wood, director of market research firm CCS Insight, said, "There were a whole bunch of bland, mid-range Android phones that made the show a real 'showcase'. A veritable 'crapfest'." 　　In 2017, smartphone sales declined for the first time since 2004, according to Gartner. Consumers are holding on to their phones longer, Gartner said, adding that "users have high expectations for new phones, but these devices have no obvious highlights, which has weakened smartphone sales." 　　Cell phone software and hardware bottleneck 　　We see now the smart terminal or see the new product release has long been no surprise in the past, in addition to the expected faster SOC, larger and clearer screen, higher and higher pixels, smart phones are tending to continue the old path of the PC era. 　　What is the reason for all the embarrassing situation in the industry now? 　　First of all, it must be mentioned that in the framework of the current mobile smart terminal, hardware + software combination of imagination has entered a bottleneck. 　　The functionality of smartphones depends on the combination of internal sensors and processors and software systems to achieve, but at present, there is no revolutionary breakthrough in the arithmetic power of cell phone processors and limited innovation in the field of sensors, making the overall lack of innovation as a set of finished smartphones. 　　In addition, as Mr. Luo said above, the technology monopoly betwee

Solve the problem of black spots on the surface of TPE products by cleaning the injection molding machine

In the production process, there are always some improper operation methods, resulting in defective products. In fact, inferior products and genuine products may not be much different, such as the appearance of black spots on the surface of the entire tpe products, such TPE products will be scrapped . Observe the surface of plastic products, if the black spot is larger, it should belong to the raw material carbonization black spot; if the black spot is dark, brittle, puffy porous, can be considered a carbonization black spot; if the black spot density is particularly large, check the raw material without obvious impurities . 　　Forming impurities black spots, may be due to foreign objects mixed into the material formed black spots, must be strictly controlled production, packaging, storage, transportation, open newspaper, mixed materials to the barrel of the various aspects of cleanliness. 　　Carbonized black spots, should be strictly controlled processing temperature, because in actual production, processing temperature and the actual processing temperature is different. On the same equipment, it is different back pressure, different cycle time, different one-time injection volume, different thermocouple insertion position, it will cause the same processing temperature under the material carbonization, degradation trend is different. In other words, when the temperature is the same, the back pressure is small, the cycle time is short, the one-time injection volume is large, and the thermocouple is inserted in the upper part of the screw barrel, the melt degradation/decomposition trend is weak, and it is not easy to produce carbonization black spots. Prevent carbonization black spot at the same time to prevent the accumulation of material, to eliminate the dead ends in the screw barrel, nozzle, runner, so that the turn has a gentle transition, to eliminate the possibility of material stagnation area. 　　The black spots on the thread surface and the wall of the screw barrel, which are deposited by the degradation of additives or carbonized materials, will be discharged under the strong shearing action in the screw barrel when the black spots are removed from their original attachment surface and enter the melt. This "discharge" process is the process of products appearing black spots, impurities. Such as the transfer of material for color production, this "discharge" impurity process is inevitable, in order to try to shorten this process, the method taken is "cleaning". 　　"Cleaning" method one: the empty melt glue cleaning screw. 　　"Cleaning" method two: into the injection table melt glue, to the empty shot glue, and then into the injection table melt glue, to the empty shot glue, and so on repeatedly, practice has proved: cleaning, back pressure plays a big role, the melt and screw strong shear. The melting speed is slow, so the melting time is also long. This is a good effect, clean foreign bodies quickly.

Introduction to metal surface injection molding TPE, TPR elastomer solution

　　A user asked on the Internet, "At present, I need to inject TPE plastic into the metal surface, but the adhesion between the two is very poor when I inject TPE plastic directly into the surface, so I can't stick to it basically. TPE through this layer of material can be closely bonded together, it is difficult to separate. Just like silicone rubber and metal coated with a layer of silane coupling agent can be very strong together."

Several important points when designing plastic mold for TPE products

Generally, when designing a plastic mold, after determining the mold structure, the detailed design of each part of the mold can be carried out, i.e., determining the dimensions of each template and part, cavity and core dimensions, etc. This will involve the main design parameters such as material shrinkage. This will involve the main design parameters such as the shrinkage of the material. Therefore, the dimensions of each part of the cavity can only be determined if the shrinkage rate of the molded plastic is specifically known. Even if the selected mold structure is correct, but the parameters used are not appropriate, it will not be possible to produce quality plastic parts.
