To achieve high quality products from Plastic Injection Molding (PIM) process it is very essential to identify the defective operations in automatic manner which most challenging task. This paper proposes a Machine Learning (ML) approach detect complex faults occurrence during PIM process. During initial sampling of molding and low time consumption concentrate on suitable determination paramete...

Ultraprecision aspheric cutting process using a monocrystalline diamond tool is widely used in the manufacturing of optical components and their molds/dies. Plastic lenses are molded by injection molding an amorphous electroless Ni-P plated molds/dies decreasing lens surface roughness required. Generally, oblique one methods to decrease force burr, roughness. In this study, was applied mold mat...

Mate...

acrylic resin denture bases undergo dimensional changes during polymerization. injection molding techniques are reported to reduce these changes and thereby improve physical properties of denture bases. the aim of this study was to compare dimensional changes of specimens processed by conventional and injection-molding techniques.sr-ivocap triplex hot resin was used for conventional pressure-pa...
