Specifications

vacuum forming process :

 1. Extruding plastic sheet:

ABS, HIPS, PP, PE, PC, PETG, PMMA resin granules are extruded or coextruded into thermoplastic sheet--textured, smooth, gloss or matt, fire-retarded or UV resisted.

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 vacuum formed plastic.  

5. Trimming edges:

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

6. Drilling holes: Drilling often follows the trimming. Other post forming processes include decoration, printing, strengthening, reinforcing and assembly.

7. CNC Processing: For more accurate and faster speed post acrylic vacuum forming 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 vacuum formed products will be carefully checked in terms of dimensions, surface finish, strength, colour requirements and so on.

9. Cleansing and Packaging All acrylic vacuum formed plastic products are cleaned before packaging. Products are wrapped with plastic film.
