Gate & runner in molding are channels through which molten material is injected into the mold cavity.

• Gate is the opening through which molten material enters the mold cavity

• Runner is the channel that connects the gate to the sprue or main injection point

• Proper design of gates and runners is crucial for ensuring even distribution of material and preventing defects

• Examples: Submarine gate, edge gate, hot runner system

Shrinkage in plastic refers to the reduction in size of a plastic part after it has been molded.

• Shrinkage occurs as the plastic cools and solidifies after being injected into a mold.

• It is important to account for shrinkage when designing molds and parts to ensure proper dimensions.

• Factors affecting shrinkage include material type, mold temperature, cooling rate, and part geometry.

• Common methods to compensate for shrinkage include adjusting mold design, using shrinkage factors...read more

Molding is a manufacturing process where a liquid or pliable material is poured into a mold to create a specific shape.

• Molding involves heating a material until it becomes pliable, then shaping it using a mold.

• Common types of molding include injection molding, blow molding, and compression molding.

• Examples of molded products include plastic bottles, car parts, and toys.

SMPS, amplifier, and power supply are all electronic devices used to regulate and control electrical power.

FIFO stands for First In, First Out. It is a method used for inventory management where the oldest stock is sold or used first.

• FIFO is a method used to ensure that the oldest inventory items are used or sold first.

• It helps in reducing the risk of inventory obsolescence.

• FIFO is commonly used in industries like retail, food, and manufacturing.

• For example, in a grocery store, products with the earliest expiration dates are sold first using the FIFO method.

Yes, SAP T Codes are transaction codes used in SAP systems to execute specific functions or tasks.

• SAP T Codes are shortcuts to access specific transactions in SAP systems.

• They are alphanumeric codes that represent a specific task or function.

• For example, T Code 'MM01' is used to create a material master record in SAP MM module.

Joins are used in databases to combine rows from two or more tables based on a related column between them.

• Types of joins include inner join, outer join (left, right, full), cross join, and self join.

• Inner join returns rows when there is at least one match in both tables.

• Outer join returns all rows from one table and matching rows from the other table.

• Cross join returns the Cartesian product of the two tables.

• Self join is used to join a table to itself.
