Airflow mould board
The generic all-purpose board will fit your machine exactly and do the job. However, it will be the same for a cola-bottle and a comforter – only the moulds differ. The shape of the mould and the positioning of the moulds on the board determine what parts of the board are critical. For example, those places where moulds are closest to each other, leaving a thin powder bride. Or, the hole in the comforter needs to be open in the mould boards, so that the air can escape when the mould is pressed into the starch. Deltavorm offers airflow boards that are optimized for the specific product.
The mould board will follow the outline of the mould. This will ensure maximum airflow between and around the moulds. Once the correct wire mesh is assembled on the mould board, the moulds are postitioned in the right place and are mounted with one or two bolts.
Mould board construction
1. mould; 2. wire mesh; 3. mould board: ventilation distancer (optimized for the mould) + ribs (optimized for strength and weight); 4. bolts
When a mogul machine presses a mould board into starch, the air must escape through the mouldboard. When the mould board is pulled out of the starch, the air must flow back into the cavities in the starch. The more free the air can flow through the mouldboard, the better. The starch will be undisturbed and the print quality will be optimal.
Generally, we will produce a complete metal airflow mouldboard with PTFE coated or polished aluminium moulds. They will last many years with a minimum of maintenance and easy cleaning.
A full-metal airflow mouldboard will cost more than a generic board with (detectable) plastermoulds, because of the chosen material and required engineering, but it will offer superior return-on-investment for high-volume products.
Advantages of airflow boards:
- Fewer production problems and better product quality by better airflow
- Increased yield: product-specific design can increase production speed
- Improved handling by lighter design
- Improved product quality by optimized airflow
- Improved print quality if combined with aluminium moulds bolted to the board
- Easy maintanance and cleaning of board
- Improved return-on-investment for high-volume products
- Reduced down-time (fewer damages to moulds)
- Reduced replacement costs (fewer mould replacements needed)
- Long lasting board and moulds
- Higher yield by increased production speed
