The manufacturing method of the arc base plate mold of the magnetic absorption light box is as follows: firstly, the required radian is made of wood plate or 1.8-thick density plate, and the standard radian ratio is 1:3.25. Use a 0.9CM or 1cm thick density board to cut the required size, and place an arc on each side of the bottom (if the density board is an arc, fix the two arcs together to increase the strength). Use the air nail gun to nail the density board on the arc. You can also nail a few radians in the middle, and you can nail them with a straight density board on both sides. Female models are the same as before. The good radian is made into the same mold as the base plate, and the base plate adopts the full plate nail. When using 0.9-thick, 1-thick or 1.2-thick density plate to make circular arc mold, the selection of density plate thickness is determined by the size of characters (because the thickness, size and material of density plate determine the degree of bending).
The magnetic absorption light box shall nail the common mould of the characters on the arc plate, and nail the same arc in the characters. According to the physical properties of acrylic plate, the best cooling time is 24 hours, at least 12 hours. Cooling method of acrylic base plate: after taking the acrylic base plate off the platform, turn it to the bottom of four sides, and pad it with bracket, so that the base plate is suspended and the acrylic floor surface does not touch the ground. Each middle part of the upper four sides of the acrylic base plate is compacted with heavy weight, and then the dust gun side by side gently presses its surface with hand, so that it reverses the surface of the rapid cooling set. Press for a period of time. After the completion of the male and female mold, the four sides and four legs of the male mold are processed with sandpaper or file to make the edges and corners slightly round. The corners tilt slightly to release the mold. Sand the bottom of the mold. No matter how large the arc is in the middle of the arc floor mold, try to ensure that the height of both sides is about 3cm. It is very easy to crack the quadrilateral plate when it is too high to form. Finally, the pressure absorption molding. 18、 The method of making arc text mould is to make the same radian as that of the base mould. According to the size of the base, the radian in the middle is slightly larger than the font. When you do this arc, you have to keep the inner arc and the outer arc at the same time. Acrylic cooling method: remove the acrylic from the platform and place it in a flat place with four sides pressed to prevent deformation of the bottom.
