Funnels & hoppers
The hopper or funnel is a conical (tapered) hollow body and is used to fill containers with small openings relative to the size of the container. Liquids such as water or fine-grained materials such as sand, gravel or granulate are added to the wide inlet of the funnel or hopper and then flow via the thinner outlet (neck) into the vessel.
Hoppers and funnels have also become firmly established in industry. Whether round or square, all types find their own appropriate area of use. Hoppers are used in every small or large filling system. The material to be used, the size and shape used to produce hoppers and funnels are always dependent on the subsequent use.
We produce hoppers and funnels made of stainless steel (e.g. 1.4301), made of aluminium, mild steel such as S235 / S355, made of deep drawn steel DD11 or even from wear-resistant steel (e.g. Hardox). They can be produced using different methods. One option is to Roll the material, in order to achieve the required shape. Another option is to produce them by bending with subsequent folding to achieve the appropriate degree of rounding. The end edges are then joined together by welding or tacking.
