Use of conventional flexible polymeric mould materials yields to longer solidification time of (wax/plastic) patterns in soft tooling process, thereby reducing the rapidity of the process to a great extent, which is not desirable in present competitive market. In this work, approach of particle-reinforcement with mould materials is introduced to reduce the cycle time of Soft tooling process and...

The demand of highest possible effectiveness is put on all production processes, while the highest quality is demanded from products. These requirements are particularly justifi ed in the steel industry, due to high cost of technical equipment assembly and production cost. In such conditions continuous processes are of signifi cant meaning, since they facilitate maximum utilization of productio...

In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...

it is highly desirable to employ biopreservatives of the antioxidant and antimicrobial properties to avoid the side effects associated with the use of synthetic preservatives. cake batters containing essential oil extracts of some such iranian native herbs as: lemon balm (melissa officinalis), camel thorn (alhagi maurorum) and ajwain (trachyspermum copticum), were prepared. the chemical composi...

comnode classification within membrane residue curves (m-rcms) currently hinges on lyapunov’s theorem and therefore the computation of mathematically complex eigenvalues. this paper presents an alternative criterion for the classification of nodes within m-rcms based on the total membrane flux at node compositions. this paper demonstrates that for a system exhibiting simple permeation behaviour...

The plasmodium of the slime mould Physarum polycephalum has recently received significant attention for its value as a highly malleable amorphous computing substrate. In laboratory-based experiments, microand nanoscale artificial circuit components were introduced into the P. polycephalum plasmdodium to investigate the electrical properties and computational abilities of hybridised slime mould....

Novel syntactic foams made of starch and ceramic hollow micro-spheres were developed. Foams of four different micro-sphere size groups were manufactured with either preor post-mould gelatinisation process. Compressive failure behaviour and mechanical properties were evaluated. Not much difference in failure behaviour or in mechanical properties between the two processes (preand post-mould gel) ...

In recent years, public concern about indoor mould growth has increased dramatically in the United States. In this study, lactic acid bacteria (LAB), which are known to produce antimicrobial compounds important in the biopreservation of food, were evaluated to determine if the same antimicrobial properties can be used to inhibit mould fungi that typically colonize wood. Based on biomass measure...

A variety of parts in microsystems technology are manufactured by injection moulding of polymeric materials. In Particular the high cooling velocity affects negatively the process and the resulting part properties. The scope of this paper is to investigate the influence on the reachable flow length in injection moulding of different polymeric materials. The results indicate that the mould tempe...

A mould release agent is an additive that makes the moulded product easy to detach from mould, it forms a protective film on ensure surface quality of mould. Mold agents are divided into water-based agents, oil-based and powder-based agents. Water-based widely used because they have advantages low price, good effect, green environment protection, smooth casting surface, air tightness automatici...
