Plastic coating of plywood using extrusion technique

Plastic Coating of Plywood Using Extrusion Technique

The target was to study and develop industrially suitable methods to apply thermoplastic coatings on plywood. Typically, wear and climatic resistance for wooden sheets, such as chip board and plywood, is achieved by thermosetting resin coating (e.g. phenolformaldehyde). However, economical and environmental issues are driving towards thermoplastic coatings (e.g. polyethylene) in such products. ...

Optimal Performance of Plastic Extrusion Process Using Fuzzy Goal Programming

Abstract—This study optimized the performance of plastic extrusion process of drip irrigation pipes using fuzzy goal programming. Two main responses were of main interest; roll thickness and hardness. Four main process factors were studied. The L18 array was then used for experimental design. The individualmoving range control charts were used to assess the stability of the process, while the p...

Condition Monitoring of Plastic Extrusion Machine Using Artificial Neural Network

Proactive programs as condition monitoring justify the most extreme demands of plastic industry as safety, reliability and cost-competitiveness with other ones. It is a less expensive and precautionary way, rather than the reactive one. Condition monitoring program is utilizing different emerging technologies for better results. The aim of this practical research work, carried out on a plastic ...

Plastic deformation of 7075 Aluminum Alloy using Integrated Extrusion-Equal Channel Angular Pressing

Grain refinement improves the mechanical properties and formability of metals and alloys. So far, several different grain refinement methods have been proposed and studied. Severe plastic deformation is one of the most promising and efficient methods. Therefore, in the present study the possibility of imposing a two-step severe plastic deformation (Extrusion and Equal channel angular pressing) ...
