An introduction to heat transfer

This exploration is identified with the demonstrating and control of a plastising twin screw extruder (TSE), which will be utilized to accomplish the nature of the item ceaselessly. TSE is a broadly utilized procedure strategy for joining crude polymers. Intensifying structures a polymer with better properties that fulfills the need of current plastic applications. In view of the information on the procedure, factors and distress factors chose were controlled. Choice of controlled factors was finished utilizing a choice strategy, which contains a steady position relationship between's the procedure creation variable and nature of the item factor and dynamic thoughts. In the color, two procedure yield factors, softening temperature (Tm) and bite the dust when the dissolving pressure (Pm) was picked as the controlled variable. Polymer extrusion is a significant compound procedure that is utilized in consistent creation tubing, pipes, film, sheet, covered wire and other polymer items in the plastic business. Roughly 60% of all polymers go through the extruder before making the last item. In the polymer extrusion process, the crude material appropriate for liquid creation in wanted size is pushed to a metal bite the dust. A few units, including blending, warming, working, haircutting, and response and molding, can be worked in a solitary machine.

Adaptive control of plastic extrusion process

One of the biggest environmental challenges of Vietnam is plastic wastes without recycling such as bottle, cans, plastic bag. The Vietnamese government have recognized these problems and called the reforming campaign to develop the sustainable technology to re-producing the wasted plastic. Thus, this research aims to contribute to deal with the issue by designing a plastic recycling machine. To satisfy domestic market of over 120 units at the first time, this research attempted to make a small machine at a low cost, but its throughput still reaches about 8kg plastic/hour and it can run within 16 consecutive hours a day. Hence, most of components is expected to be supplied by local vendors. As the result, the product price as well as maintenance cost is anticipated to be reduced. With the aim to produce the automated machine can incorporate continuous raw materials flow and at the same time move melted plastic in screw conveyor as defined by the regulation of the Programmable Logic Controllers (PLC) with timer to detect a velocity of melted plastic which come out from a nozzle of the screw conveyor and go to a mold. The hydraulic pressure, then, applies force to compressing and forming products. There are potential risks that can happen in fact, to deal with them. That is a reason Computer aid engineering and Finite element method modeling were conducted to make sure the force pressed in mold sufficiently and controlled the thickness of production as customer requirements.

Model Design and Numerical Simulation for Plastic Recycle Machine

This research focuses on introduction and evaluation of machine parts manufactured by bound powder deposition method, a new approach in metal 3D printing. After a review of metal 3D printing technology, a new approach for metal printing, called bound powder deposition, is introduced. Several specimens manufactured by the bound powder deposition are then conducted for experimental works. In the experimental works, the crystal structure of the printed part is investigated. In addition, typical mechanical proprieties of the printed part produced by the bound powder deposition are tested and compared with other those produced by other 3D printing and metallurgy methods.
