Q1. Explain stress, strain curve diagram with example?
Ans. 
Stress-strain curve shows relationship between stress and strain in a material under tension.
• Stress-strain curve is a graphical representation of how a material deforms under stress.

• It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• Example: Steel has a high yield strength, so its stress-strain curve shows a steep initial slope.

• Example: Rubber has a low yield stre...read more

Q2. What is DOF? How many degrees of freedom from any object
Ans. 
DOF stands for Degrees of Freedom. It refers to the number of independent parameters that define the configuration of an object.
• DOF is the number of ways a rigid body can move in 3D space.

• For a rigid body in 3D space, there are 6 degrees of freedom - 3 translational and 3 rotational.

• Examples of DOF include linear motion along x, y, z axes and rotational motion around x, y, z axes.

Q2. 2. what is shutt off angle in molding?
Ans. 
Shut off angle in molding refers to the angle at which the mold halves meet and close to form a complete part.
• Shut off angle is crucial for ensuring proper part ejection and preventing flash formation.

• It is typically between 0.5 to 3 degrees, depending on the material and part design.

• A larger shut off angle may be required for parts with deep cavities or complex geometries.

• Improper shut off angle can lead to part defec

Q4. 4. In pp plastic material coating or painting are used?
Ans. 
In pp plastic material, coating is preferred over painting for better adhesion and durability.
• Coating is commonly used on PP plastic material for better adhesion and durability

• Painting is less preferred on PP plastic due to poor adhesion and durability

• Examples of coatings for PP plastic include polypropylene-specific primers and adhesion promoters

Q5. 5. How to define undercut angle in plastic?
Ans. 
Undercut angle in plastic is the angle between the side wall of a mold and the vertical direction.
• Undercut angle is important in plastic injection molding to ensure proper release of the part from the mold.

• It is typically measured in degrees and affects the draft angle required for the mold.

• A larger undercut angle allows for easier part ejection but may require more complex mold design.

• Examples of parts with undercut a...read more

Q6. 6. what is warpage & sink marks in plastic & how to prevent?
Ans. 
Warpage and sink marks are common defects in plastic parts caused by uneven cooling. Prevention methods include proper gate design, cooling system optimization, and material selection.
• Warpage is the deformation of a plastic part due to uneven cooling, leading to dimensional inaccuracies.

• Sink marks are depressions on the surface of a plastic part caused by uneven cooling and shrinkage.

• Prevention methods include proper g...read more
