What the hell is a car "inverted mold"?

Presumably all car owners have heard of the word "inverted mold", but do you really know this modification technology? Next, please follow in Bian Xiao's footsteps and see what "inverted mold" is!

Due to the influence of the interior space of the carriage, the installation position of most original car horns is defective. With the continuous improvement of people's pursuit of music, car stereo modification has gradually become a trend, and the gameplay is more diversified. In order to create a better listening environment, make the sound directivity more accurate, and combine the internal structure of the vehicle to make the interior more exquisite, the "inverted mold" technology came into being.

The concept of inverted mold

Using wood, putty, acrylic board, leather and cloth, the process of transforming the original car interior is called "inverted mold". The common inverted mold positions are: A-pillar, trunk, door panel, etc.

Automotive audio reverse molding materials mainly include the following:

1. Plastic material

Simply put, it is the material used to make the model, such as putty or rubber mud. If it is a large model, FRP glue is needed to enhance the rigidity of the mold. The trunk shape also needs a lot of boards to make borders and speakers.

2. Surface treatment materials

The surface treatment material is what we can see after the completion, which can be leather (usually artificial), spray paint, electrostatic flocking and high-elastic fiber flannel. Anvil cloth is also commonly used in the trunk.

3. Accessories

Mainly some catalysts, glue and the like used for reverse molding.

The purpose of reversing the modification mode of car audio

In order to solve the problem that the modified horn does not match the size of the original car, and also to make the modified car look better and the interior more beautiful.

In addition to being beautiful, the sound quality has also been greatly improved, not only in directivity, because after installing the bass, there will be a certain volume behind the speaker, and the bass will sound fuller and more solid, and it will not sound so loose as it is directly installed on the door panel. So if you install bass, you can pad two speaker rings, not just one. The so-called melody hole effect is this principle.

If the mold is poured well, the effect will be different, the sound field will be improved and the sound will be transparent and beautiful. Reverse molding still plays a great role in improving sound effects, but I suggest that you must choose a store with excellent brand and technical quality to operate.

Is bad luck really that simple?

There are several necessary tools for car audio refitting: baking gun, Jigsaw, grinder, knife, putty, sandpaper, wood board, glue and so on. The quality of the material also determines the quality of the inverted mold!

Mould inversion can only be done by masters with the title of senior technician (engineer) or above, and all the masters with the title of senior technician (engineer) or above have more than ten years' working experience. The effect of inverted mold should not only consider beauty, smoothness and symmetry, but also design orientation and orientation according to acoustic knowledge, which is not as simple as measuring several dimensions as everyone thinks.

According to different models, the master will design different reverse mold schemes for each car. All reverse mould construction needs to be carried out in a transparent and dust-free automatic woodworking room, and all tools adopt the most advanced machines; When the master works, the dust left behind will be automatically pumped away, which will give the master a high-quality construction environment, make the master pay more attention to pouring the mold, and the effect of pouring the mold will be better.

So it seems that bad luck is not easy!
