Manufacturing Technologies: Shaping & Molding Processes
1. Manufacturing Technologies
Manufacturing technology is a set of transformation processes applied to a material during preparation. Requirements for piece manufacturing include:
- Prepared for assembly
- Faithful to the pre-established design
- Reasonable cost of materials and energy
- Reliable quality control
2. Shaping by Melting and Molding
A mold is a container with a cavity. Molten material is poured into the cavity, and solidifies in the shape of the cavity.
2.1 Mold Components
- Bottom: Main cavity or half

ASP.NET GridView Control
The ASP.NET GridView server control is a server-side rich-data control for repeated-value binding. It is the successor to the .NET Framework version 1.1 DataGrid control.
The GridView is a powerful control that provides the ability to display, format, paginate, and edit data.

A machine is a system composed of one or more mechanical parts with moving components and, at times, other assemblies. A mechanism is a set of mechanical elements that perform guidance and transmission functions related to the movements and forces within a machine. Joints can be classified as fixed or detachable.
Fixed Joints: Used when the union must withstand significant mechanical forces, and dismantling is not necessary.
Detachable Joints: These elements are linked but can be dismantled. Some

Car Transmission Systems
Epicyclic Train
This system builds speed transmission relationships, offering several transmission ratios and reverse spin. Key components include the planetary gear and ring gear. Some systems use two epicyclic trains, uniting a planetary gear with other fitted pieces.
Brakes and Clutches
Cinta Brake
The drum rotates while a band tightens when the piston receives pressure, activating the brake.
Disc Brake
Oil pushes the piston, compressing discs of different materials. The housing

Water distribution networks ensure a sufficient and continuous water supply to all subscribers and have the precise extent to cover the entire population.
Distribution Control Tanks
Given that the water flow is constant during the clock in the case of driving shot, or during certain hours only in the case of elevation, and which, in turn, the flow of consumption is essentially variable, the use of tanks is needed where excess water can be stored when the flow of consumption is less than the input

Tables and Keys
A table (or relation) represents a specific entity of data. It’s composed of:
- Primary Key: A unique value identifying each tuple (row).
- Tuples (Rows): Instances of the entity.
- Attributes (Columns): Characteristics of the entity.
Primary Key: Unique across all tuples, used for identification and querying.
Foreign Key: Links to the primary key of another table.
Data Integrity
Ensures data accuracy, consistency, and validity through rules and constraints.
- Entity Integrity: No primary key attribute
