Individualising series production: Actually a contradiction in terms, yet Speedpart can offer it, thanks to its own mould making and 3D printing solutions. With their process, the individualised parts are produced by 3D printing, inserted into the injection moulding machine and then overmoulded. In this way, individualised parts are possible from a batch size of 1. On the one hand, this enables the production of parts that are identical as a series but can still be numbered or coded. This process is interesting for various applications in electrical engineering for plug connections or in the automotive industry. Speedpart already offers this service for one-piece injection moulded parts, small quantities or in series of up to 100,000 pieces.

At Speedpart, the combination of metal laser sintering (DMLS) and CNC production is the fast way from the CAD data set to the injection mould. A major advantage of DMLS at Speedpart is that moulds can be produced in tool steel without the limitations of classic machining processes: Internal channels for optimised mould tempering can increase the quality of the injection moulded parts and also shorten the cycle times on the injection moulding machine. Sintering of bionic trusses, free forms and fine details allows new design freedoms. Undercuts, e.g. for elastomer moulds, are sintered directly.

Thanks to the finest layers from 20 μm and wall thicknesses from 0.5 mm, the finest details and good surfaces are possible, which only require minor finishing. The desired finish is carried out by Speedpart specialists in precision work on the workbench, on the CNC machine or with special polishing systems.
