Lab Report On Injection Molding

Introduction: This experiment is going to test the ability of antacids and how they absorb acid to see which is a better buffer. An antacid neutralizes acid, and this helps the most with heartburn. Heartburn is where stomach acid is regurgitated back into the esophagus, and this causes a burning feeling in the chest (Oxford University Press, 2017). A buffer is a source of hydroxide ions that can absorb hydrogen ions, which in turn keeps the pH stable (Mader, 2017). In this experiment, the different antacids that are being tested to absorb the hydrogen ions from stomach acid are the buffers. The pH scale helps determine how acidic or basic a solution

The Greater New York Dental Convention held on 26th November 2017 focused on issues relating to dental hygiene and practices. There were some exhibitions in that convention displaying various dental diseases, hygiene practices, and dental technologies. One of the exhibits that caught my eye was the exhibition by Amanda Vera and Tiffany Andron from New York City College of Technology. First of all, their poster was well designed with a well selected them for the poster which was visually attractive. The color schemes were appealing to the eye and could easily attract passersby. The layout of the poster was also clean with words having a clear font, not too dull.

Increasing the efficiency of the equipment, by upgrading components and eliminating the equipment’s inefficiencies is another option for energy savings. Substantial savings can be realized by changing the fixed speed motors on the injection molding equipment, to variable speed motors that use less energy during less demanding cycles. Fixing the leaks in the equipment’s hydraulic system as well as performing other routine maintenance will keep the equipment efficient and running as intended. Whereas these changes can increase efficiencies, they are simply bandages that will need to be changed.

There were various aspects in this investigation that had to be conducted carefully to maintain a safe environment. Prior to conduction the experiment, the students tested how far the foam would travel up to beaker to ensure that a sufficient sized beaker could be used to prevent any spillages. As the practical involved the use of hydrogen peroxide (H2O2), students had to be cautious when using this substance. Even though the hydrogen peroxide (H2O2) was only 6% concentrated, extra care was taken to avoid contact with the skin as it may cause a slight burning sensation. Furthermore, the beakers were labelled to prevent any cross contamination, especially between the hydrogen peroxide (H2O2) and water, as they were both colourless. For example, if hydrogen peroxide (H2O2) was used instead of water to dilute the Catalase concentration, the

We found that Polypropylene was our 5th unknown. Polypropylene (C3H6) or more commonly referred to as PP, is used for labeling, packaging, textiles, and stationery. In 1957, the crystallization of polymer was discovered. Soon fabric was made from the polymer, and was in high demand. It can also be used for moldings of cars, film, tape, foam and carpet. Polypropylene can not be glued to any objects or itself, and so it is melded. After Polyethylene, Polypropylene is the highest produced synthetic plastic. Polypropylene also holds up well over time, which is one of the reasons that it is the second most produced plastic. The melting point is between 130-171 degrees celsius. Because polypropylene is tough and flexible it can be used as an engineering plastic. Finally, polypropylene can be used be manufactured into a living hinge. A

In Figure 4, Young's modulus is plotted against yield strength. The diagonal line in the figure represents the material index M= σy/E. Materials below the diagonal line are the best candidate materials because they will remain elastic while providing the maximum conformability. All materials that cost more than $2.20 per pound and have a UV rating of "poor" were eliminated. Also, only materials that can be made through the polymer extrusion process were considered. The candidate materials are listed in Table 1 and ranked by the material index. The current material, TPV, is included in the table for

Battenfeld HM 40/130 is the machine used in the laboratory session to mold Polypropylene. Thermoplastic materials such as nylon, polystyrene, polythene and polypropylene can be used in a process called injection molding.

Mold is a microscopic element that belongs to the Fungi family. It reproduces by forming spores and usually thrives on moist cellulose based objects. They occupy an important ecological niche as they are responsible for braking down organic substances. However, mold poses several health risks to human beings and they should be removed as soon as they are detected.

Custom Molds Inc., manufactures custom designed molds for plastic parts and produces custom made plastic connectors for the electronics industry. Established in 1987, the primary focus was to provide manufacturers or electronic connectors a source of high-quality custom-designed molds for producing plastic parts. After building a strong brand reputation through the designing and fabrication of precision molds, Custom Mold’s expanded into the limited manufacture of plastic parts. The operations at Custom Mold’s include a process for fabricating molds and a second process for producing plastic parts.

To calculate the expected number of pipette tips needed per month take the number of pipette tip per sample to multiply it with the average sample analysed per month, 5 x 100 = 500.

3D printing is a technology that was invented in the early 1980s by a man named Charles Hull (Ventola, 2014). Since its creation, 3D printing has branched into many different aspects of the world and is being utilized in fields like the automotive industry, medicine and is even being used for everyday purposes. Later on, Charles Hull founded a company called 3D Systems which developed the first ever 3D printer. In 1988, Hull and his company 3D Systems, put forth the first commercially available 3D printer. From this point on, 3D printing would be advanced and evolved to the point where it would have the opportunity to create a revolutionary impact on the world we
