ELECTRICAL INSTALLATIONS:
The electricity used to meet our energy needs (housing, buildings and industries) But there are serious dangers such as fires and electrocucions if facilities do not meet the appropriate security.
Low Voltage Electrotechnical Regulations (REBT) technical conditions and guarantees must be met by electrical installations connected to a low voltage supply in order to:
-Preserve the safety of persons and property.
-Ensure the normal operation of these facilities and prevent disruptions that could cause other facilities and prevent disruptions that could cause other facilities and services.
-Contribute to the technical reliability and efficiency of economic facilities.

General cargo Terminals. Classification: - Conventional: These terminals Are very old installations, which at the beginning did not move unitized cargo. Their layout is simple and in general they do not require large extensions for Cargo handling and manipulation. Distribution and dimensions, as well as Installations needed depend on the cargo type manipulation and they have open Storage areas as well as light storage facilities, silos and horizontal Storage. ¿How do they operate? For the cargo loading and discharging, They use mobile shore cranes with high lifting capacity between 20 to 30 mt, For the storaging and interconnectitvity, depends on the cargo presentation, They use: platforms, rolling cars and reach stackers and reclaimers.

What is Injection Molding:

Injection Molding is a manufacturing process for producing parts in Large volume. It is most typically used in mass-production processes where the Same part is being created thousands or even millions of times in succession.

Injection Molding Machine

Why Use Injection Molding:

The principal advantage of injection molding is the ability to scale Production en masse. Once the initial costs have been paid the price per unit During injection molded manufacturing is extremely low. The price also tends to Drop drastically as more parts are produced. Other advantages include the Following:

Molding is very repeatable.

 That is, the second part you produce is going To be practically identical to the first one etc. This is a wonderful... Continue reading "Plastic molding site:.Uk" »
