Explain the mechanical property issues that could be caused if pressure is not correctly controlled in Injection Molding process

KiRa [710]4 years ago
6 0

Answer:

As soon as the material that is molded contacts the mold in the injection operation, it begins to cool and solidify. For this reason the injection must occur quickly, so that the cavity is filled while the material is molten. This is achieved with a high injection pressure since the compound is very viscous, despite the high temperatures. The molten material must overcome the resistance offered by friction, in the nozzle and cavity, which could not be done if the pressure is lower than required, preventing the proper filling of the mold.

If the injection pressure inside the mold is higher than the appropriate one, it exceeds its closing force, the partition line of the mold is forced to open; allowing the molded compound to escape from the cavity (resulting in burr and additional work is required in order to eliminate it).

How can you evaluate whether the slope of the dependent variable with an independent variable is the same for each level of the
s2008m [1.1K]

Answer:

By running multiple regression with dummy variables

Explanation:

A dummy variable is a variable that takes on the value 1 or 0. Dummy variables are also called binary

variables. Multiple regression expresses a dependent, or response, variable as a linear

function of two or more independent variables. The slope is the change in the response variable. Therefore, we have to run a multiple regression analysis when the variables are measured in the same measurement.The number of dummy variables you will need to capture a categorical variable

will be one less than the number of categories. When there is no obvious order to the categories or when there are three or more categories and differences between them are not all assumed to be equal, such variables need to be coded as dummy variables for inclusion into a regression model.

Rzqust [24]

Answer:

Marcus would have to take an exam administered by the national council of examiners for engineering and surveying.

Explanation:

Civil engineers design, construct, and maintain projects regarding infrastructure. A civil engineer also looks after the systems in the public and private sectors like roads, buildings, and systems for water supply and sewage treatment.

In order to pursue a career in civil engineering, Marcus aims to work for the city council as a civil engineer. Therefore, he would have to take an exam administered by the national council of examiners for engineering and surveying.

natulia [17]

Most business owners begin his business in order to increase profit and to expand.

<h3>What are Business Practices?</h3>

This refers to the various ways in which a business owner decides to organize his business and the policies which guides it.

With this in mind, we can see that Mr X believes that it is a good business practice to <em>prioritize the work</em> that seems the most difficult and the most likely to kill their projects but this is not a good business practice because it can put the entire business in jeopardy.

Please note that your question is incomplete so I gave you a general overview so that you could get a better understanding of the concept.
