How it’s Made: Metal food production funnel

This month’s how it’s made covers a curvaceous project which we helped reverse engineer and redesign for food production line machines. A fairly simple to look at funnel, but complicated to make from metal, involving precision design and skilled manufacture.

Made from 2mm stainless steel, perfect for the heavy duty nature of it’s purpose and working environment, this is how we made a food production funnel…

Laser Cutting

We start following this case study when it’s reached the laser cutter. It went through the same steps as all our projects, by starting with a consultation with the client and drawing up CAD designs and renders for approval before producing the final product in the factory.

The laser cutter makes quick work of the 2 mm steel the funnel is being manufactured from.

The funnel involves some intricate detailed curves to enable the funnel to bend effectively…

Precision Bending

Once cut, the parts are straight to the press brake operators.

They take each part and mark carefully the lines for each bend, alongside programming the machines to bend each gradient in succession.

Once the calculations are done, it’s time for the magic to happen!

Welding

….and then constructed by the welders into the completed funnel shape with simple tack welds to hold all the parts in place.

Manufacturing Metal Food Funnel

Once tack welded into shape, it’s onto the main welding. This funnel involved precision TIG welding to make sure it had the professional and clean finish required for the customer.

Once the funnel was welded, you can see it had a bit of work required to remove the blemishes and spruce it up to a polished finish.

Electrifying Finishing…

That means it was time for the grinding, linishing and polishing team to do their magic, but this time there isn’t a grinder or sander in sight…

Polishing - Metal Food Funnel

The funnel is earthed as we apply our special solution which literally burns off the welding marks and reduces all signs of welding on the finished product.

The funnels were then quality inspected by the QA team and packed off to the customer in Cheshire.
