Sheet metal forming processes, the purpose of which is to give the shaped material
appropriate mechanical, dimensional and shape properties, are characterised by different …

In the sheet metal forming industry, rapid tools, especially those made of polymeric
materials, are increasingly used for small to medium volume productions, to compress the …

Epoxy-based composite molds are frequently used for polymer and wax materials injection.
Three kinds of epoxy-based composite mold inserts fabrication methods are proposed in this …

Purpose Custom-designed metal bellows require alternate ways to produce the die to
shorten lead time. The purpose of this study is to explore the possibility of using Additive …

The rapid tooling approaches were most sought after for the low-volume production of sheet
metal parts within a short duration. This study presents an investigation of direct rapid tools …

Rapid tooling technology is regarded as an important method of reducing the cost and time
to market in a new product development process. Silicone rubber mold is frequently used in …

Conventional, dies are manufactured subtractive for sheet metal forming. Beside the forming
process, high tooling costs, material exertion and energy consumption, the die production …

Purpose The purpose of this study is to produce a low-cost sheet metal forming mold made
from the low melting point Bi58Sn42 (bismuth) alloy by using an open-source desktop-type …

A bridge tooling is developed for fabricating the temporary mold inserts of aspheric lens
using silicone rubber materials. Prototype material of the aspheric lens is not recommended …

With impulse forming technologies like electrohydraulic and electromagnetic forming, the
punch in a stamping process is replaced by an impulse that acts in a short period and …
