What is injection parameter?
Injecting parameters into a macro means that you can take a parameter of a Supplier and inject the value of that parameter into that macro. For example, using the Report Variable macro, you can declare a variable with a constant value of “10”.
What are the injection Moulding machine parameters?
The process parameters such as cycle time, fill time, cooling time, injection time, injection speed, injection pressure, holding pressure, melting temperature, mould temperature and so on need to be optimized in order to produce finished plastic parts with good quality.
How is induction heating measured?
For temperature control, induction heating systems use pyrometers, also known as infrared thermometers. These instruments measure temperature without contact and have no wearing parts. Based on Planck’s radiation law, a pyrom- eter captures the infrared radiation and converts it to a temper- ature value.
How is heat transferred through induction?
Induction heated products are not relying on convection and radiation for the delivery of heat to the product surface. Instead, heat is generated in the surface of the product by the flow of current. The heat from the product surface is then transferred through the product with thermal conduction.
How do you set injection molding parameters?
Injection of main process parameters are as follows:
- (1) cylinder temperature.
- (2) the melting temperature.
- (3) the mold temperature.
- (4) injection pressure.
- (5) injection speed.
- (6) time parameter (molding cycle)
What injection molding process parameters affect the part quality the most?
Through empirical and theoretical analysis, the most significant process parameters affecting surface waviness is the melt temperature, followed by mold temperature, injection pressure and packing pressure.
What is induction heating principle?
Induction heating is the process of heating electrically conductive materials like metals by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to melt down steel, copper, brass, graphite, gold, silver, aluminum, and carbide.
On which principle induction heating process is based?
electromagnetic induction principle
The induction heating works on the electromagnetic induction principle. Moreover, it is also known as eddy current heating.
Which parameters are fixed before starting injection Moulding?
Injection of main process parameters are as follows:
- (1) cylinder temperature. Melting temperature is very important, the shot cylinder temperature is directional.
- (2) the melting temperature.
- (3) the mold temperature.
- (4) injection pressure.
- (5) injection speed.
- (6) time parameter (molding cycle)
How do you calculate injection pressure?
Pressure (lb/in2) x Projected Area (in2) = Force (lb.) Here are a few other important tips for calculating the right press size for your plastic injection molded part.
How do you reduce part weight in injection molding?
the lT method, part weight control is achieved by controlling the temperature and pressure of the melt in the cavity at gate freeze time. This time is considered to occur when the cavity melt pressure starts to decrease from its peak value.
How is heat generated in an induction heating system?
In ferromagnetic and ferrimagnetic materials, such as iron, heat also is generated by magnetic hysteresis losses. The frequency of the electrical current used for induction heating depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.
How does induction heating work in ferrimagnetic materials?
Induction heating. In ferromagnetic (and ferrimagnetic) materials like iron, heat may also be generated by magnetic hysteresis losses. The frequency of current used depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.
Why is inductive heating used in manufacturing industries?
In manufacturing industries, this process offers speed, control, and consistency. This method is efficient, quick & non-polluting. During inductive heating, the loss of heat can be solved with the help of Lenz’s law. This law shows a way effectively with the heat loss which occurs in the method of inductive heating.
