Stainless steel funnel （hopper）

Stainless steel funnels are widely used. Their core function lies in ‌efficiently and hygienically guiding the transfer and filtration of liquids or fine particulate matter‌. Whether it is for household use in the kitchen or for food packaging machinery, injection molding machines, dryers, canning machines, or automated production feeding equipment, stainless steel funnels are all used.

The traditional method of making funnels

Traditional funnels are generally made by rolling cones and welding，First, a fan-shaped sheet is cut by plate laser cutting, then a conical body is formed by rolling with a hydraulic conical machine, and finally the interface areas are welded.

The disadvantage of traditional funnel

The traditional funnel is processed by conical rolling and welding. The dimensional accuracy of the funnel is not high. The weld seam position is difficult to grind due to the deformation of the material after heating during welding. After grinding, the surface of the weld seam is uneven and the appearance quality is not high. Moreover, it is prone to dirt accumulation.

Why use metal spinning to make a funnel

The spinning funnel is a funnel made through the metal spinning process, which uses rotation and pressure to shape metal sheets into the desired form. Compared with traditional stamping or welding processes, spinning funnels have several significant advantages, especially in terms of strength, precision and production efficiency.

No welding, high strength

The spinning process can achieve the one-time integral molding of the funnel without welding or splicing, avoiding the strength weakening and potential leakage risk caused by weld seams, and significantly improving the structural integrity and durability of the product.

Smooth surface and high precision

The inner wall of the funnel after spinning is smooth and flat, without seams or burrs, and the outer wall has only fine lines, meeting the high cleanliness requirements (such as in the food and pharmaceutical industries). The diameter accuracy can reach ±0.1mm and the length accuracy can reach ±0.2mm, ensuring consistency in assembly and use.

High production efficiency and controllable cost

CNC spinning equipment can achieve automated continuous production, especially suitable for medium and large-scale manufacturing. The equipment is independently developed and customized by the manufacturer, which can optimize process parameters according to demand, shorten the production cycle and reduce unit costs.

One-time process forming

Metal spinning can complete various processes such as trimming, flanging and rolling in one go in the mold. Traditional funnels still require flanging machines and rolling machines to complete each process.

Dinnovation metal spinning advantage

CNC metal spinning ＞

Dingchuang CNC Spinning has 10 CNC spinning machines. The maximum diameter of the stainless steel funnel that can be spun can reach 1.3M, the height can reach 0.5mm, and the thickness can reach 5mm.

Polishing machine

Large funnels are usually heavy and difficult for people to handle. The best way to polish funnel by large automatic polishing machine, which ensures stable quality and uniform brushing patterns. Our polishing machine can polish up to a maximum diameter of 1.5 meters and a height of 1 meter.

Exterior surface polishing

Interior surface polishing

Automatic laser welding

We have Panasonic manual argon welding machines, A automatic straight seam welding machines and a 4-axis 2000KW laser welding machine. The weld surface is smooth without sand holes, easy to grind and has a low polishing cost.
