12th Tooling Conference & Exhibition - Tooling 2022

Low Pressure Die Casting (LPDC) is a widely used process for the manufacturing of automotive components. These components have high mechanical requirements, which
are difficult to achieve reproducibly within standard boundary conditions in LPDC. To ensure part feasibility, some areas are oversized to improve filling behavior and therefore local me-
chanical properties. Targeting these issues...

For industrial mechanical food processing steps, like cutting, slicing, grating, passing or similar applications, tools of martensitic stainless steels are preferably used because of their high hardness and corrosion resistance. The latter is decisive to avoid contamination of foodstuff by elements transferred from the steel alloy into the processed food.
In this work various martensitic...

Efficient processes offer a promising approach to meet requirements from global trends like sustainability or resource shortage. The process of orbital forming is established
for the manufacturing of functional components with a gradient in sheet thickness, like for example in a clutch. Nevertheless, the present tool setup disposes a lack in economic efficiency and is restricted by a maximum...

Improving tool life under cyclic loadings is of great economic interest, since forming tools often fail due to fatigue fracture initiated at volume or surface defects. Increasing the fatigue strength of tool steels can be achieved through improved steel making or properly chosen case hardening. Diffusion layer plasma-nitriding has never been investigated statistically or...

ROTA 2030 (in English, Route 2030) is a Brazilian strategic program for developing the automotive sector. Among its priority lines, it focuses on bringing competitiveness to the Brazilian tooling industrial sector. Called “Ferramentarias Brasileiras Mais Competitivas” (in English “More Competitive Brazilian Tool Shops”), it is a line organized in four axes, among which the first three...

The growing importance of lightweight construction to reduce resource consumption is leading to the increased use of multi-material systems consisting of components with varying geometric and mechanical properties. However, the joining processes to manufacture these assemblies are gradually reaching their limits, which is why innovative processes and methods are required. To enhance the...

Intelligent material combinations for the production of multi-material systems as well as lightweight construction to save weight are becoming increasingly important in industrial applications. But the joining process of dissimilar materials, such as high-strength steel and aluminium as well as steel and continuous fiber-reinforced plastics (CFRT), which are often used in multi-material...

Copper-Beryllium precipitation hardening alloys are widely used to manufacture molds in plastic injection moulding due to the excellent thermal properties combined with good mechanical strength and corrosion resistance. However, the lower hardness and wear resistance compared to tool steel, as well as the higher cost, limited their wider use. A tool steel cladding on copper alloy substrate...
