1. Extruding plastic sheet:

ABS, HIPS, PP, PETG,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 resistant

2. 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.Machine large 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 Packaging

All 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.
