The first is the selection of materials
Currently seen in the domestic acrylic panels, basically imported or foreign joint venture production, the quality of the panels should be said to be relatively good.
The second is the mold
Acrylic panel is formed by vacuum positioning, suction pressure, even if the same word, different sizes also need different molds, and the mold itself requires high quality and good precision. Because the precision of the mold itself, the quality is directly related to the quality of acrylic products.
Third is the post-production
Now acrylic blister production is basically mechanized production, the application of new equipment to improve production efficiency at the same time, greatly reducing the labor intensity of the workers, acrylic blister material after the basic molding, but also after milling, milling, grinding and other processes, and finally will be laying the light box light source, baking varnish after the production of the completion.
Fourth is the picture processing
Henan this is a professional advertising light-emitting character design and production company. Production of a variety of luminous characters
According to the different needs of customers, through screen printing directly. Competition picture transfer to the acrylic sheet, after the vacuum suction molding, the picture has a person, animal or commodity images, but also re-absorption established .
LED exposed light-emitting word production specific methods:
In the production of LED light-emitting word before, then let us understand the LED light-emitting word (LED exposed light-emitting word) production materials: acrylic, galvanized sheet, stainless steel, titanium plate and other basic materials.
1, the word first whole sheet of machine tool punched holes (according to the size of the LED to determine the aperture);
2, the engraved word welded three-dimensional edge (and baking paint the word of the same practice);
3, sanding the corners of the word, don't have a burr;
4, baking paint treatment;
5, LED lights, there are two kinds of installation: A, one is the earlier practice (material). Is a former relatively early practice (low material costs but more labor), is to use the bare lamps one by one connection, calculate the current, and then sealing glue to do waterproof treatment, this is more prone to problems; B, a now with a lot of ways (high material costs but less labor), is to use a lot of manufacturers do a good job of each lamp with a rubber sleeve with good waterproofing treatment connected to a good string of lights, the market has been a lot of this kind of way is also easier to maintain, protect the big point.
LED three-dimensional light-emitting word production method
The first step & gt; & gt; Calculate the number of LED modules: the use of equal spacing arrangement, simulation of the distribution of the LED modules on the computer, the initial budget for the number of LED modules required. Module spacing depending on the brightness required between 3-6cm, the thickness of the light-emitting word can be selected between 5-18cm.
The second step & gt; & gt; Calculate the total power consumption, power supply selection: the budget for the number of LED light source module × the power of a single module = total power consumption. It is recommended that the power supply selection to leave a margin, 75% of the rated power use. According to the use of environmental selection of ordinary or waterproof power supply.
The third step & gt; & gt; installation of modules: ① clean mounting surface; ② double-sided adhesive tape on the bottom of the module; ③ even layout, connect the wires; ④ installed the word slot panel and measure the effect; ⑤ final product.
Resin light-emitting word production method:
Resin light-emitting word is composed of three parts: shell, filler material, light source. The shell part of the plastic (ABS) injection molding or metal plate (iron, stainless steel, titanium, etc.) welding molding; shell filled with raw materials for the modified liquid resin casting molding; light-emitting source is used in the ultra-high brightness semiconductor light-emitting diode (LED).
1. Do a good job of the word mold, the layout of the line. Note: The interface between the line and the mold can be sealed with glass glue or silicone, and must be sealed to avoid resin leakage.
2. Pour the resin material. That is, 3 parts A + 1 part B Note: The resin level is about 5mm from the top of the mold to stop casting. The thickness of the resin casting layer is about 2cm. This layer is cast as a colorless and transparent casting layer. It can be called light guide layer.
3. When the light guide layer is cured, cast the second layer, A + B + screed + color paste that is, 3 parts of A + 1 part of B + (A 2-3%) screed + (A 0.5-1%) color paste for the second layer of the resin system, the layer casting full of the entire word mold, called the screed layer.
4. Natural temperature, or heating curing to make the screed cured.
5. Repair any defects.
6. Note:
1) The inner wall of the mold can be coated with reflective paint, so that the light emitted by the light source is repeatedly refracted inside the mold to avoid loss of light source.
2) need to control the thickness of the light-guiding layer and the uniform layer of light, the above is the thickness of 2.5cm - 3cm thickness of the resin light-emitting word. 3. A and B mixed must be used up within 12 hours (this time will slowly thicken, if you feel that the consistency can still be poured, then you can continue to use it), such as can not be used up then discarded, can not be poured back into the A or B. If you can't use it up, discard it and don't pour it back into A or B. Henan this is the advertising design and production company
