Plastics is one of the world’s largest and fastest growing industries, ranked as one of the few multi-billion dollar industries. Due to the vast improvements in polymers and production processes, plastics are now amongst the world’s most widely used materials, with the world consumption of polymers surpassing steel in volume and weight. Injection molding represents approximately 32% (by weight)...

The plastic industry is a very important manufacturing sector and injection molding is a widely used forming method in that industry. The contribution of this work is the development of a strategy to retrofit control of an injection molding machine based on an embedded system microprocessors sensor network on a field programmable gate array (FPGA) device. Six types of embedded processors are in...

The development of many photonic devices, such as photonic integrated circuit, optical sensors, and photovoltaic devices, demands low-cost and reliable fabrication technologies to fabricate sub-wavelength features. Here, we report a programmable nanoreplica molding process, which is capable of producing photonic devices with a variety of submicrometer patterns. The process utilizes a stretchabl...

Injection molding process is one of the most important methods of forming in the plastics manufacturing industry. Shrinkage and out of roundness are phenomenons that affect the final product quality. In this study, the effect of the thickness of cylindrical parts from polypropylene material on shrinkage and out of roundness has been investigated. For this purpose, injection molding process is s...

The structure of car seats is becoming increasingly complex, with mixing wire conformation and plastic injection. over-molding process implies some labor, which can be reduced if novel solutions are applied in this manufacturing area. handling the wires used main problem identified process, wasting time both feeding extraction molds process. However, these machines usually extremely compact fre...

Justification of production and manufacturing processes overtime, process capability in the concept of statistical control has been of great importance because it has promoted the production of products that satisfy the expectation of consumers. This paper aimed at promoting the adoption of quality process capability design in a bid to improve the process stability of a process and improve the ...
