I. What's vacuum forming?Vacuum forming is a process in which a thermoplastic sheet is heated to the appropriate temperature, stretched around or into a mold or pattern, and conformed to the mold by applying vacuum pressure between the mold surface and the plastic sheet. Because heating of the material to be formed is required, vacuum forming is considered a thermoforming process.II. Vacuum Forming Machined process:1. Extruding plastic sheet:ABS, HIPS, PP, PE, PC, PMMA resin granules are extruded or co-extruded into thermoplastic sheet or plate that textured, smooth, gloss or matt, fire retardant and UV resistant2. Vacuum forming:After being heated, the plastic sheet is stretched onto or into a mould, and held against the mold by applying vacuum between the mould surface and the sheet to form designed shapes.3. Cooling to keep shape:Once formed the plastic need to cool before being released from the mould. To speed up the cooling cycle, fans are fitted and activated once the plastic part is formed.4.Machinelarge products:Our machine could be restructured to make larger plastic vacuum forming plastic products, with maximum dimensions of 3000*2000*800*10mm (L*W*H*T)5. Trimming edges:Extra material is firstly trimmed before more accurate processing. Sawing is often used in the stages. Polishing is made additionally to smooth the edges.6. Drilling holes:Drilling often follow the trimming. Other post forming processes include decoration, printing, strengthening, reinforcing and assembly.7. CNC Processing:For more accurate and faster speed vacuum forming plastic products processing, CNC is often used. The machine is computer programmed to select correct cutting tools and angle to suit each area.8. Examination and checking:Before packaging, all our vacuum forming plastic products will be carefully checked in terms of dimensions, surface finish, strength, color requirements and so on.9. Cleaning and PackagingAll vacuum forming plastic products are cleaned before packaging. Products are wrapped with plastic film to prevent scratches and cartoon boxes are used or other methods are applied as required.About us:Amei Brothers is a professional vacuum forming products manufacturer in Shenzhen.The max size we can do is 3000*2000*800mm.The thickness can reach 10mm.The materials include PMMA,ABS,PP,PE,PET,PETG,etc.We can produce good according to your design.If you have any pictures or designs, pls send it to us.It would be appreciated if you could provide us 3D drawings.
