4. Raw material extrusion.
Also, a good quality raw material sheet will influence the product’s quality too. The raw material sheet production is through machine extrusion. Then the vacuum forming sheet will have a good performance, the impact strength is very good. Some raw material sheets can be used at lower temperatures. For now, DITAI also establishes a raw material sheet production line. And our target is to have 3 production raw material lines, then we can produce all the raw materials by ourselves and can control the quality of the raw material at the beginning.
The raw material sheet size, glossy level, thickness, color, etc can be controlled here. So is the cost.
5. Vacuum forming Production Steps.
● The vacuum-forming aluminum mold is installed in the vacuum forming machine, then our worker will heat the mold to a suitable temperature.
● After the mold is ready, we will put the raw material sheet or roll it on the vacuum forming machine table.
● Then we will use the heater for the vacuum forming and heat the raw material into good condition and suitable for vacuum forming.
● Once the raw material is ready, the vacuum forming machine will push the mold and make the mold touch the raw material until it totally covers it.
● When the raw material touches the mold completely, the machine will vacuum forming the mold at the backside. And the air between the mold and plastic is evacuated. This makes the raw material touch the mold perfectly.
● Finally, we will use an air cooling machine on the vacuum forming to cool the raw material, then separate the finished plastic product and the mold. Once everything is ready, our worker will take the product out of the machine. The vacuum forming process is done.
For now, DITAI has 14 sets of vacuum forming machines, one machine is the full automatic vacuum forming machine. These machines are suitable for producing different sizes of customized plastic products. The biggest plastic size we can produce is 4000x2000x1000 for now this is the biggest vacuum forming machine in Dongguan and our CEO designer and DITAI create this machine. Based on our workers’ over 10 years of experience in vacuum forming technology, The temperature and delivery time can be controlled strictly here.
