How to Fix the Broken Out Screw Holes in the Laptops - Internal Hardware

This video is of India's Lappy brand. The American brand is QBond. This seems a little bit better than Epoxy Putty because the dust easily fills in the crevices, and it's easier to work with compared to the Epoxy Putty. The Epoxy Putty is sticky work. It's not nearly as easy to work with, but it can be done. It is more wasteful though because the powder and glue trick can be more accurately measured out. With the putty way requires extra to be mixed, so that the job is not half done without enough of it mixed. It's a race before it dries. In the end some is always thrown away because it's better to have more than enough than not enough. This problem does not exist for the powder and glue technique because the material is always in the bottle/s. In this video she uses Plast-Aid powder and a syringe full of superglue. I like the syringe. You can also use Baking Soda or Baby Powder with superglue. Plastic Welding: How To Instructional Video by Techspan And then there's welding plastic. Hehe This guy uses the "washer" method. Cut out plastic such as credit card plastic, and then cover the hole from in the laptop case. It's to remake the hole for the screw, so that it does not pull through the laptop case. I prefer to use either viscous liquid epoxy with a gel viscosity or epoxy putty instead of the plastic washer trick. Just tape the hole on the outside, pile up the epoxy on the inside, and drill through it. That remakes the screw hole. Some liquid epoxies dry with a gloss and transparency. That will blend with the case's color. The epoxy putty will stand out after it is dry, and so will some of the liquid epoxies.

1. How Gate Design Affects Your Plastic Parts

The runner and gate system used in plastic injection molding is responsible for directing molten plastic from the nozzle of the molding machine into the cavity of the tool. The gate architecture and its location affects cycle times, tooling costs, lead times, the location of witness marks and many other potential defects that are commonplace for injection molded parts. Here's what every product developer should know about the basics of injection mold gate design. Having this information will help you to make informed decisions when you are consulting with your supplier to make injection mold tools. The location of an injection mold gate directly affects the quality of the finished part so consider these general rules: The gate should be placed away from pins, cores and other internal obstructions. Otherwise this may cause weld marks as molten plastic flows around them and reforms on the other side Gates should be placed closest to thick walled areas to ensure complete Improper gate location can cause part if the build volume of the entire part is filled unevenly Gates are areas of high stress. Try to locate gates away from locations on the finished part that will be affected by or the potential degrading of plastic that happens in these areas Gates need to be located in areas that will be easy to degate, either manually or automatically. Note that some plastics are susceptible to high sheer forces and therefore can only be degated manually Thin walled parts might need flow channels or additional gates to provide a sufficient volume of plastic in a minimum All gates force molten plastic under pressure into the cavity which accelerates and heats the plastic as it does so. This creates a variety of effects which may need a change to gate design strategy. The most common defects include: If the gate is too small the resulting pressure drop through the gate will cause jetting, that is, spraying into the cavity rather than flowing smoothly. Jetting causes wavy distortions called "worming". This may require a decrease in pressure, an enlargement of the gate or both. High injection speed through the gate creates heat through friction. Too much heat at this point may cause the resin to decay by destroying molecular bonds. However, slowing down the injection speed to avoid degradation may cause other defects such as poor mechanical strength at weak weld lines. And slower cycle times means fewer parts per hour, increasing processing costs. It's possible therefore to divide a given volume of resin over a number of separate gate openings. This helps to dissipate pressure and avoid overheating, but it also creates multiple flow fronts which may cause weld lines and gas traps where these fronts meet inside the cavity. 3. The Difference Between Hot and Cold Runner Systems A hot gate/runner system uses an electrically heated cylinder to deliver pre-heated plastic into the mold cavity. The runner is built into the mold in the form of a manifold plate and a number of hot runner drops. Cold runner systems are less expensive, but the length of the runner represents plastic that will be wasted at each cycle, which in turn increases costs. Moving a witness mark to a more advantageous location should be balanced against the increased consumption of material due to longer runners. 4. The Pros and Cons of the Most Common Gate Types There are different sizes and gate designs to consider, and each type has their advantages and disadvantages. Here are the most common ones: Edge gates are used most often. They are machined into the mold at the parting line and fill the cavity from the side of the part. Easy to enlarge if necessary without removing the mold from the machine Location of the witness mark may not be ideal Plastic flowing from a single gate will create noticeable weld lines as it flows around obstructions in the mold High injection pressures and velocity at the small gate opening can cause the plastic to degrade A gate built into the sprue directly where it enters the fixed or A-side of the tool. Able to inject large volumes of plastic quickly Ideal for round or cylindrical parts where concentricity is important Leaves behind a large witness mark with the potential for a sink mark on the opposite side For a submarine gate design, the runner directs plastic to the edge of the cavity at the parting line, but then the gate drops below the parting line and tunnels upward to fill the part from below. This design is only possible on two-plate mold construction. Moves the witness mark to a more desirable location Excess gasses can be pushed up and out of the mold from below More complex, expensive and time-consuming to manufacture An alternative type of edge gate, the fan maintains a consistent thickness but spreads out to increase the volume over a larger area. Recommended for polycarbonate plastics. Good for increasing the flow volume for thin-edged parts May leave a large, tab-like witness mark that must be post-processed Are You Ready To Start Your Next Project?

3. Does anyone have stories about disgusting things they have found in their food?

Once I found a large piece of plastic (looked like it was the cut off top of a bag of guacamole) in my taco salad. Last month I was eating fish and chips and a huge clump of hair stuck in the batter of the fish and *vomit* in mine and my toddlers mouths. It was horrible, I had to take my kids dinner away from him and go fish hairs from his mouth while trying not to vomit. he was so sad :(

KUU A10 Laptop Review: The Best Notebook Under 350 Euros?
Do you have a notebook? How do you usually use it? What are the main features that you think a product of this type should have? These are the questions that more or less any type of user asks himself when deciding to buy a new laptop. However, it is not always easy to answer these questions due to various factors. Sometimes, in fact, you think you have to make a certain type of use of a product which then, in the end, turns out to be completely useless. It also happens, however, that we become passionate about this world and decide, at some point, to learn how to manage more and more applications and programs. It becomes crucial, therefore, to choose the right model among the many offered on the market. In addition to being various price ranges, there are also totally different characteristics between the various models, so the choice becomes increasingly difficult. For example, you might just turn your gaze to ours KUU a10 laptop who, in the last few days, has accompanied us in various work activities. It is difficult to say, however, if it is actually worth buying it, even in the face of what is offered by the competition. We, therefore, are here for this, to shed light on its functioning and on all its strengths within its Full review. Unboxing As often happens in these cases, the company has taken steps to include the bare minimum in the sales package, finding the following products inside: KUU a10 laptop; wall power supply, with European socket; warranty certificate; short sales manual, also in Italian. Design & Materials Pick up the sales box, open it and take a look inside. Grab your new KUU a10 laptop and try to describe this product with the first word that comes to mind. I think the first one that could come to your mind is “light” since to the touch it seems to be in front of a featherweight. Be careful, however, because we are still in the presence of a laptop from 1,3 Kg which due to the presence of plastic, in the totality of the external structure, seems to be much more manageable than others. In any case, I did not appreciate this choice of polycarbonate on the entire surface, even the internal one, which almost denotes the presence of a cheap product. Taking a look at the price, in fact, we are on the same wavelength as other devices that show at least some metal components. By handling this device a little, then, you can notice some creaks that do not bode well for the future as regards the assembly of the product. I report, however, also the general dimensions of this notebook, which measures 375 x 245 x 22 mm, therefore, a device that is also quite demanding in this respect. I would have expected something more, as already mentioned, on a constructive level. I must say, however, that this device has also disappointed me in another respect, namely that relating to the provision of ports. Taking a closer look at the KUU laptop, in fact, we notice the presence of two ports USB-A 3.0 left and right as well as the audio jack 3,5mm, the hole to connect the power cord, and a door mini HDMI. There is really nothing more. Surely, however, the fact remains that the company could have done something more in terms of robustness since with slight pressure on the keyboard there is an important flexion. Even if this problem does not affect its daily use, it remains a critical issue to report. Taking a look at the back we see how this KUU a10 laptop presents two accesses to the hardware. With the smaller compartment, it is possible to replace the SSD da 256 GB, while with the larger one we access an area adjacent to the keyboard and trackpad. I have not yet understood, however, what its real usefulness can be. Keyboard & Trackpad Having had the opportunity to try many similar products I already knew, more or less, what to expect from the feedback area of the keyboard. I was not wrong, because actually the distance between the various units is good and the accuracy is also not bad. There remains only the problem of their running which, as far as I'm concerned, is too soft. Last but not least, the layout is the American one so it will be necessary to get used to it a bit at the beginning, especially if you have never used such a system. In spite of everything, however, I did not find it uncomfortable and after a few hours of use, I hardly made any more mistakes. It is a rather large keyboard, then, also because on the right side there is a numeric keypad. I never complain about the trackpad, except in exceptional situations. I must admit, however, that this component did not impress me at all on this laptop, since the accuracy is rather sketchy. From a certain point of view, in fact, not all movements are received in the same way, and sometimes it is difficult to click on the right button, or on the right icon. I specify, in any case, that I come from a MacBook Pro from 2019, therefore of one of the devices accused of having a rather fragile keyboard but, at the same time, very comfortable when writing and phenomenal when moving around the interface, thanks to its trackpad. While the dimensions of that component on this A10 are really good, it fails to satisfy in the same way. Display On the front, it is located in an IPS LCD display da 15,6 " with resolution Full HD (1920 x 1080 pixels). I have to admit that the plastic side bezels are quite thin on three sides. In fact, this component is still predominant at the bottom. Despite this, however, we find an excellent surface anti-glare and the viewing angles are decent. This means that, even at maximum brightness, the panel can be seen quite well in direct sunlight, although we were not meant to be used outdoors. In my opinion, in fact, it behaves much better in the home, also due to its not very small size. Let's say it is a display without infamy and without praise. In its same price range, however, I found much poorer panels in terms of quality. There is no problem, therefore, in viewing multimedia content locally and in streaming, on some digital platforms such as Netflix e Amazon Prime Video. Even if the blacks are not too deep, it is still possible to enjoy a good experience when watching movies and TV series, with not too vivid colors and a sufficiently good image contrast. Hardware & Performance Onboard resides a processor Intel Celeron J4125, therefore a CPU with base clock frequency equal to 2,0 GHz and turbo boost up to 2,7 GHz. We have, then, well 8 GB of LPDDR4 RAM and an SSD 256 GB which, in any case, can also be replaced. I want to specify, however, that this storage space has been divided into two parts, namely disk C with 118 GB available and disk D with another 118 GB. From the graphic point of view, however, we find one Intel UHD 600 GPU with a base frequency of 200 MHz. I have already tried machines of this type, with similar or even identical processors, and I must say that in terms of performance we are on good levels. Obviously, you can't expect who knows what results, but in everyday use, this laptop behaves quite excellently. I want to immediately say, in fact, that it does not show any particular problems in playing movies in 4K, even beating products equipped with an AMD Ryzen 7 (see TBAO H7). This means that the system has been optimized, managing to bring out all the characters of the processor. Beyond this, then, the management of different open tabs on Chrome is discreet, although the loading of various contents puts a strain on the hardware. We must then clash with the trackpad that is really too inaccurate which very often cannot understand our intentions on the fly, carrying out other unwelcome actions. We also find this aspect during the editing of a short video on Adobe Premiere Pro, where it becomes difficult to manage all the various video and audio tracks. Everything runs quite smoothly but you can't exaggerate that much, necessarily going to insert a few effects and transitions. Lato Gaming let's say you can't complain, especially considering the hardware mounted inside this laptop. I was able to play discreetly only ad Asphalt 9, but it is necessary to make the necessary considerations of the case. The frame rate is low, so the images really are poco fluid and greatly ruin the gaming experience. In short, this product was obviously not designed for video games, so much so that after a few tens of minutes there temperature perceived on the body is quite high. This problem also emerged in the test phase, often reaching 85 ° at maximum speed. I must admit, however, that under normal conditions the heat remains on more acceptable values, climbing dramatically only with some benchmark programs and during prolonged gaming. Benchmark Software Do you want to install Linux on that machine? You can safely do this, but first, take a look at how it works with Windows 10 Pro. Thanks to this system, in fact, it is possible to enjoy the classic Windows interface, all the various apps that can be downloaded through the Microsoft Store, and much more. As always, in fact, we are in the presence of ready-to-use software that does not require any further adjustment. By purchasing this KUU a10 laptop, therefore, you may simply have to update the system before being able to use it every day. Even on this the best custom laptop brand are present all the rights of Windows, being able to manage the system as on other similar products. Connectivity & Audio As said also in the initial phase, in the first chapters, I must say that I was a bit disappointed with the hardware equipment of this product. I would have expected more ports, simply finding myself with two USB 3.0 inputs, a mini headphone jack, and the mini HDMI port. Let's say that the USB Type-C and microSD slots would have certainly been welcome. Despite everything, however, we find a module on board 802.11 Wi-Fi a / b / g / n / ac Dual Band e Bluetooth. There is no shortage, then, two audio speakers placed at the bottom, right on the lower surface. In short, an unfortunate position since if positioned on some soft plane the sound is completely covered. Beyond this, however, the quality is insufficient due to an absolutely poor sound depth. Da poco I have reviewed the TBAO H7 which shows the webcam on the front frame, bottom left. Also this device, therefore, has opted for the same solution, proposing a sensor from 2 MP. I must admit, however, that even in this case the quality is insufficient and barely valid for videoconferencing. Autonomy One is hidden under the body battery da 38Wh which manages to satisfy most users. With average intense use, always under Wi-Fi network, I mainly used YouTube, web browsing, a few tens of minutes on Premiere Pro, WordPress for writing articles, and poco other, totaling 5 hours of continuous ignition. Let's say that we are more or less in line with what is offered by the competition, managing to manage resources well even in the most hectic phases. The 24W power supply supplied in the package is not too big, showing even smaller dimensions than those of a common MacBook charger. It can, therefore, be easily inserted into any backpack without too many problems. Price & Conclusions Currently, this KUU a10 laptop is sold for about the price of 330 €. It becomes difficult to compare it with other similar products, but I must say that in this case, the performance is convincing. Although at a gaming level is in no way manages to excel, in everyday use it shows the solidity and good execution speed. I would have preferred, in any case, to be able to take advantage of a better and much more precise trackpad than the one mounted on this product. Despite this, other various accessories can be added, being able to connect, for example, an external mouse, thus improving the quality of use of this device. The fact remains, however, that the performances are there and also go well beyond expectations, managing to manage resources well in almost every situation.
