The use of stereolithography rapid tools in the

The holding pressures applied to injection molds made with the stereolithography resin are low due to the low mechanical properties of DSM Somos 7110 resin at high temperatures (Hopkinson et al 2000) Ascertaining the correct cooling periods before opening and ejecting the part is therefore very crucial to the success of the process A long cooling period leads to high contraction of the

Mechanical Properties of Rubber Samples

This article demonstrates what influence has a change in production technology on mechanical properties of rubber testing samples It compares two basic production technologies compression molding and injection molding The aim of this research is to show and evaluate to what extent the properties (tensile strength extension tear strength and microhardness) are influenced by the used

Mold Design

Benefits of Liquid Injection Molding (LIM) Faster cure cycles are a key benefit for specifying LSR for molded gaskets and seals Cure cycles of 30 to 60 seconds are typical for small gaskets and cushioning components with thin cross-sections This means a single or two cavity liquid injection mold can out-produce a multi-cavity compression mold due to the 6 to 8 minute cure cycles that are

Mold Design

Injection Stretch Blow Molding- (ISBM) the Injection Stretch Blow Molding- (ISBM) process is similar to the IBS process described above in that the preform is injection molded The molded preform is then presented to the blow mold in a conditioned state but before final blowing of the shape the preform is stretched in length as well as radially The typical polymers used are PET and PP
