1. The solution is to remove the door decorative panel and fix the harness inside. It's better to find a small sponge and stick it on the door panel where the wire bundle is located, so that the wire harness will hit the sponge and there will be no noise.If the door limiter is not maintained regularly, it will also cause abnormal noise in the door.
2. Then there is a strange sound, so what we need to do is to take out the car rust inhibitor, spray some car rust inhibitor at the hinge, and then apply a little butter, so that the friction will be greatly reduced and the abnormal sound of the door will be removed.
3. After the hinge is used for a long time, rust spots will occur, which greatly increases its friction and produces a strange sound. Then what we need to do is to take out the car rust inhibitor, spray some car rust inhibitor at the hinge, and then apply a little butter, so that the friction will be greatly reduced, and the door will be different There will be no sound.
, energy saving and environmental protection replace a large number of natural materials and save a large amount of resources; good processability, energy saving in the production process; a large number of thermoplastic plastics are used, and waste materials can be easily recycled and directly used for remanufacturing.
Reduce weight. Because the density of modified plastics is generally below 0g/cm3 (mostly about 5g/cm3), it is much lighter than metal materials, so the weight reduction effect is obvious.Modified plastics are easy to mold, which makes it very convenient to process parts with complex shapes.
Reduce costs. Generally, fillers are cheaper than resins, so adding fillers can greatly reduce the cost of plastics, which has obvious economic benefits, which is also the main reason why plastic filling modification is popular. Improve the heat resistance of plastic.
Therefore, the amount of modified plastic used in cars has increased rapidly in recent years.
Modified plastics are more and more widely used in the automotive industry. As shown in the figure below, the modified plastics commonly used to make door inner panels are ABS and PP, which are made into skeletons, and there is a buffer layer on the surface. The buffer layer is made of PP foam, TPU, knitted polyester, etc.
What are the advantages of plastic sheets?The surface is smooth and the texture is very good. The flatness and smoothness of the plastic plate can provide customers with a better visual experience and impression. Paper substrates are prone to dust and slag, which are not easy to clean; wooden sheets are prone to corrosion and insects.
Car wax Slight scratches such as sun lines only damage the surface of the paint. Such scratches have less damage to the paint and are relatively convenient to repair. It can be solved by waxing. You can choose scratch wax first, and use a waxing sponge to grind the scratch. Remember to rub it clockwise or counterclockwise.
Use the meson machine to repair. Using the meson machine, first fasten the iron wire and then try to weld, because the adjustable parameters of the meson machine are tooRelaxation, an appropriate current and appropriate power-up time that are most suitable for this repair must be adjusted. This process needs to be adjusted three to five times to find the most appropriate parameter.
How to deal with the rusty door handle: 1 Sand it with sandpaper, which is the easiest way. Buy a piece of sandpaper and then sand it on the door handle. If there are a lot of dead corners, it is recommended that you cut the sandpaper into small pieces to wipe.
There are the following methods: the simplest way is to wipe it with a cloth dipped in toothpaste, which is very effective; the car decoration strip is oxidized and can be cleaned; wipe it with water first and then wipe it dry.
[Pacific Automobile Network] Need to sit in the car and the door panelRemove the screws on the top, generally three screws, and a circle of cards next to it. After removing the door panel, you can open the door first, and then operate normally. Wrap the soft cloth with a screwdriver to pry off the front door triangle guard from the upper snap position. Remove the front door triangle guard.
Cars can be divided into two-door, three-door, four-door, five-door, etc. according to the number of doors. Method 2 The car door panel has two screws and two plastic pins. If you disassemble them, you can remove the door panel.
How to disassemble the car door 1 First, remove the inner door handle trim panel, then remove the interior panel of the car door, remove the central control lock, reversing mirror and window control switch plug, remove the wiring harness, remove the car door limiter, remove the door hinge (two people need to cooperate, the door is very heavy), and remove the assembly.
How to disassemble the car door 1 Method/Steps Turn off the ignition switch and all electrical appliances, and remove the ignition key in the 0 (pre-lock position) position. Use the disassembly wedge to remove the cover from the bottom to the top. Use a torque wrench and spline sleeve to turn out the fixing bolt. Rotate the two clips at the bottom of the door panel by 90°.
Car door panel disassembly steps: You need to prepare the disassembly tool first. First, remove the two plastic pins, so you need to press the middle point inward with a tool first, and then pry it out with scissors. Pay attention to press the middle point. Just loosen the remaining two screws with the prepared tools and remove them.
There are certain differences in the disassembly of the door interior of different brands and models of cars. Let's take Tuan as an example. The process of dismantling the door interior is as follows: preparation of disassembly tools.
The door trim panel is covered on the inner panel of the door. In addition to decorating the door, it also has the functions of convenient door switch, supporting the elbow, soundproofing and vibration absorption, dustproof and waterproofing, and protecting the human body in the event of a vehicle crash, as An important component of the car interior, the comfort, reliability and aesthetics of the door interior panel are increasingly becoming the goal pursued by people.
Cars can be divided into two-door, three-door, four-door, five-door, etc. according to the number of doors. How to disassemble the car door 3 The car door panel has two screws and two plastic pins. If you disassemble them, you can remove the door panel.
Nowadays, if the safety performance and other functions can be guaranteed, designers will try to reduce the weight of the vehicle, including the door (such as using new materials) to reduce power consumption.According to the number of doors, cars can be divided into two-door, three-door, four-door, five-door, etc.
4 Welding and correcting the replacement parts of the exterior door panel. After welding and correcting the replacement parts outside the door, install the door on the door frame and check whether the gap between the door and the door frame is consistent. Otherwise, you need to change the position of the edge folding line of part of the replacement plate until it meets the requirements. 5 Welding and correcting the replacement parts of the interior door panel.
Car door, in fact, it's not just a door. The structure of the car is very complex, and a lot of things are "arranged" in a single door. An autopsy of the car door, you will find that it has glass lifters, stereos, anti-collision beams, door locks and other accessories.
Dismantling the inner door panel of the car is actually not harmful to the car, but the premise is to follow the regular disassembly process, and the inner door of the car doorThe plate is fixed with snaps. The normal disassembly process can make the snaps fall off completely, but if the operation is wrong, the snaps will be damaged, resulting in the door panel not strict and abnormal sound when reinstalling again.
[Pacific Automobile Network] You need to sit in the car and remove the screws on the door panel. Generally, there are three screws, a circle of cards next to it. After removing the door panel, you can Open the door first, and then operate normally. Wrap the soft cloth with a screwdriver to pry off the front door triangle guard from the upper snap position. Remove the front door triangle guard.
How to disassemble the car door panel 1 Pry it up from the edge gap between the door panel and the door interior panel with a large cone, andPry open the cards inside one by one to separate them from the door panel. Pay attention to be slower when prying to avoid prying the card and scratching the door panel.
How to disassemble the car door 1 Method/Steps Turn off the ignition switch and all electrical appliances, and remove the ignition key in the 0 (pre-locking position) position.
