the first step is as follows: weighing A, B two kinds of glue according to a certain proportion, and stirring uniformly;
the second step is that: manually placing a mold on the table;
the third step: pouring the prepared AB glue into a mold;
the fourth step: spreading the glue on a mold by using a sponge scraper, and forcibly scraping the mould back and forth to extrude bubbles in the glue;
the fifth step: scraping the redundant glue off the die by a scraper blade, and finally scraping;
and a sixth step: the scraped mould is manually lifted to a baking frame plate, the whole procedure can be finished within 50 seconds at the fastest speed, 50 layers of baking frames are required, one baking frame needs 42 minutes to be made, the other baking frame is pushed into an oven after being fully made, the temperature of the oven is opened to 100 ℃, baking is carried out for 2 hours, the product is pushed out and cooled after being baked, the mould is manually taken down from the frame plate after being cooled, a layer of glue residue can be left on the plate, the glue residue on the plate needs to be manually shoveled one by one, and the plate is shoveled for later use. After the mold is cooled, the mold is placed in a self-made demolding machine, a product is demolded, the demolding machine can only be placed to 15-20 molds at a time, and the product can be stirred from the mold only by stirring and kneading for 3 minutes. The product can not be completely separated from the mold, the product is adhered to the front and the back of the mold, the product is shaken up by the mold which is operated by people one by one, the silica gel mold which is shaken up is cleaned up by transparent adhesive tape one by one for standby, so that the time spent by one mold product from front to back is as long as 43 minutes, meanwhile, a large amount of manual follow-up is needed, the power of an oven is 25 kilowatts, one mold is scraped, kneaded, torn and pulled, and is baked at high temperature for a long time, the service life of the mold is greatly shortened, one mold can be scrapped for only 25 times, one mold is 42 yuan, each mold product is 2.8 thousands, the cost is very high when the product is spread out, in the process, the product can be delivered in a day after a large amount of molds are used (about 6000) in normal production, meanwhile, a large number of ovens and baking frames are needed, which deviates from the national advocated energy-saving and emission-reducing guidelines.
At present, the commonly used resin material is glue formed by thermally curing A, B components, commonly called AB glue, and the glue needs a long time for forming in a mold, so that the production time and the cost are greatly wasted, and the production efficiency is reduced. At present, the resin products seen by people have a problem of yellowing which is difficult to overcome, the resin products can slowly turn yellow after 3-6 months, and the yellowing is accelerated especially when the resin products are exposed to high temperature or sun. The brightness of the like products is presented by the glossiness of the products, so the products are not glittering enough and the colors are not vivid enough.
