large capacity vacuum formed plastic car roof luggage box parts

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 .

Production flow

1. Extruding plastic sheet: 

ABS, HIPS, PP, PE, PC, PETG, PMMA resin granules are extruded or co-extruded intothermoplastic sheet--textured, smooth, gloss or matt, fire-retarded or UV resiste

2. Vacuum forming to shape:

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 desired shapes.

3. Cooling to maintain 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. Making large product: 

Our machine could be restructured to make larger plastic ABS thick vacuum forming plastic shell, with maximum dimensions of 3000*2000*800* (L*W*H*T)

5. Trimming edges: 

Extra material is firstly trimmed before more accurate processing. Sawing is often used in this stages. Polishing is made additioanlly to smoothen the edges. 

6. Drilling holes:  

Drilling oftens follow the trimming. Other post forming processes include decoration, printing, strengthening, reinforcing and assembly

7. CNC Processing: 

For more accurate and faster speed post thick ABS vacuum forming plastic shell processing, CNC is often used. The machine is computer programmed to select the correct cutting tools and angle to suit each cutting area.

8. Examination and checking:

Before packaging, all our thick vacuum forming samples and products will be carefully checked in terms of dimensions, surface finish, strength, colour requirements and so on.

9. Cleansing and Packaging 

All ABS thick vacuum forming plastic shells are cleaned before packaging. Products are wrapped with plastic film to prevent scratches and cartoon boxs are used or other methods are applied as required.
