Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold.
Molten material is injected into a mold cavity
The material cools and solidifies, taking the shape of the mold
Commonly used for producing plastic parts
Can also be used for producing metal, glass, and ceramic parts
Back pressure is the resistance to the flow of molten plastic in the injection moulding machine.
It is the pressure exerted by the machine's screw on the molten plastic.
It helps to ensure that the plastic is properly melted and mixed.
Too much back pressure can cause the plastic to degrade or burn.
It is measured in pounds per square inch (PSI).
There is no such term as 'suck buck' in injection moulding. It may be a mispronunciation or a term used in a different industry.
There is no known term in injection moulding called 'suck buck'
It may be a mispronunciation of a different term
It could be a term used in a different industry altogether
Short molding is a process where the plastic material is injected into the mold cavity for a shorter duration than usual.
Short molding is used to produce smaller parts with faster cycle times.
It requires precise control of the injection speed and pressure.
Short molding can result in lower part quality if not done correctly.
Examples of short molding applications include electronic components and medical devices.
PP material stands for Polypropylene. Its melting point ranges from 130°C to 171°C.
PP is a thermoplastic polymer widely used in injection moulding.
It has a low density and high stiffness, making it ideal for packaging and automotive industries.
The melting point of PP varies depending on the grade and can range from 130°C to 171°C.
PP is resistant to chemicals and has good electrical insulation properties.
Examples of PP ...
ABS stands for Acrylonitrile Butadiene Styrene. Its melting point is lower than its upper limit.
ABS is a thermoplastic polymer commonly used in injection moulding.
It is known for its toughness, rigidity, and resistance to impact.
The melting point of ABS is typically around 105-110°C, which is lower than its upper limit of around 220°C.
ABS is commonly used in the production of automotive parts, toys, and electronic hous
Sink mark and gate mark are common defects in injection moulding.
Sink mark is a depression on the surface of the moulded part caused by uneven cooling or insufficient packing pressure.
Gate mark is a small protrusion or indentation at the point where the plastic enters the mould, caused by the gate being removed from the part.
Both defects can be minimized by adjusting the moulding parameters, such as cooling time and pa...
5S and 6S are lean manufacturing methodologies used to organize and maintain a clean and efficient workplace.
5S focuses on workplace organization and standardization of processes to improve efficiency and reduce waste.
6S adds safety as a sixth element to 5S, emphasizing the importance of a safe work environment.
Both methodologies involve regular audits and continuous improvement to maintain a high level of organization...

DC current is the flow of electric charge in a constant direction.
DC stands for Direct Current.
It is the opposite of AC (Alternating Current).
DC current flows continuously in one direction.
It is commonly used in batteries and electronic devices.
Examples of DC current include the current from a solar panel or the current from a car battery.
