Forming/stamping 304 sheet

[Mark FryParticipant @markfry71618]

Hi all,

I'm planning to have 1,000 pieces of the following made. Material is 304. Does it require several dies be made for multiple stage stamping? Is it even feasible?

I wonder if something like this could be made for less than £2,000 all up.

Any thought appreciated.

Try contacting a company in China.

Assuming your dimensions are in mm not inches it doesn't sound impossible. I've had similar sized parts made in Malaysia for a few pence each and reasonable tooling costs. However you might want to reconsider the design to eliminate the rolled section and the specification of angles to 1/100 degree is a bit extreme!

Yes, units are in mm.

Does each die cost much to make? How is pressing compared to injection moulding (as plastic) in terms of tooling costs?

Will the rolled section be difficult?

At a modest charge out rate of £25 an hour that gives you 80 man hours. Take off that the cost of materials and heat treatment for the tool steel and you have no hope in the UK or Europe. Far east may come up with something in your budget. An aluminium mould to injection mould the item in plastic may work out cheaper, only you know the application.

It was a few years ago now but I think it was around £1500 for the tooling, a lot more in Europe. Plastic moulding tools tend to be a lot more expensive.

Yes, the rolled section will be difficult. It will probably need a multi-stage tool or multiple operations and thus more tooling cost.

I don't know the cost of press dies, but a few years back I manufactured a number of dies/ moulds for forming vulcanized rubber parts, a die maker valued them at an average of $NZ 1500 each for the six dies, cost to me minus time, about $NZ 10, each mould cost $NZ 6 per fill, most of the parts sold in USA for $US 50 each. With these dies I was able to use hot rolled mild steel as no heat treatment was needed, for press tools these would require hardening and tempering, there for needing a high carbon steel. I don't know how big the press would be for an item like that.
