BENEFITS RUBBER PAD FORMING
Extremely suitable for small series thanks to low investment in tools
Tooling costs are low, 5 to 10% of deep drawing toolings.
Single tools, time to market is short
High-tech look for a high-tech product
Optimum flow through round shapes
Not bound to sheet thickness
No surface damage
Often possible to jointly replace conventional operations such as lapping, welding and post-processing by rubber pad forming
Simple integration of functional properties, such as: lightweight, stiffness, cleanability, flow and design
Easy to achieve cost savings
LIMITATIONS RUBBER PRESSING
Too expensive for very large numbers due to higher variable costs
Maximum sheet thickness approx. 4 mm (depending on shape)
ADVANTAGES RUBBER PRESSING
SMALL AND MEDIUM-SIZED SERIES – DEEP DRAWING VS RUBBER PAD FORMING
The initial investment in tools is extremely low for rubber press technology. That alone gives you a great advantage. But, to be honest, the variable costs for rubber pad forming are higher because processing takes more time. In case of conventional deep drawing, this is just the opposite; high tooling costs, but lower variable costs. When these are compared, a break-even point is reached. Below that point, rubber pad forming is more advantageous, above this point you should opt for conventional deep drawing.
In addition to the advantage in tooling costs – which facilitates the launch of a new product – you can easily add or combine functional properties with rubber pad forming in the product. For example reinforcement with ridges, so you can ‘cut back’ in sheet thickness and have less material costs, and you won’t have to provide your product with separate reinforcement. Or how about pressing round corners? This eliminates edging, welding and post-processing.
In addition, it is often possible to bring down the Total Cost of Ownership. The round shapes make products easier to clean, which in turn leads to lower changeover costs (i.e. the food market).
