How much compressed air is required for the hot press to produce the connector

The compressed air requirements of the hot press for the production of connectors vary according to the type of equipment and process, the working air pressure range of common hot presses is between 0.4 and 0.7MPa, and the specific dosage shall be comprehensively calculated in combination with equipment specifications, production rhythm and the number of equipment running at the same time.. The following is a detailed analysis:

1. typical hot press compressed air demand parameters

1. INP166E hot press: It is clearly required that the compressed air pressure range is 0.4-0.6MPa, which is suitable for the crimping process of precision electronic components.
2. Large size pulse hot press: The working air pressure requirement is 0.5-0.7MPa, which supports TAB process combination crimping of 12-80 inch TFT panel, reflecting higher requirements for air pressure stability of large-size equipment.
3. General equipment for heat treatment workshop: The pressure requirement of pneumatic handling equipment covers 0.1-3.0MPa, of which 0.5MPa is the common intermediate value, reflecting the differential demand of different processes for air pressure.

Calculation method of 2. compressed air quantity

1. single equipment usage: Refer to the rated gas consumption (such as m & sup3;/min or L/s) marked on the equipment nameplate or technical manual. For example, a certain type of hot press is marked with a gas consumption of 0.5m & sup3;/min, the air consumption per hour is 30m & sup3;.
2. Overlay calculation of multiple devices: If the workshop runs n identical equipment at the same time, the total gas consumption = single gas consumption x N x simultaneous use coefficient (usually 0.6-0.8). For example, 3 sets of equipment are running at the same time, the total gas consumption = 0.5 × 3 × 0.7=1.05m & sup3;/min.
3. dynamic adjustment mechanism: It is necessary to consider the impact of production rhythm changes (such as intermittent operation of equipment) on the actual gas consumption, and it is recommended to carry out actual measurement and verification by installing a flowmeter.

3. key influencing factors

1. equipment Specifications: Large-size equipment (such as 80-inch panel crimping machines) usually requires higher air pressure and flow due to the increase in the size of the driving parts.
2. process complexity: Multi-stage heating procedures (such as four-stage temperature control) may increase the number of pneumatic control valves, resulting in an increase in gas consumption.
3. system efficiency the pipe diameter, the number of elbows and the pressure drop of the filter will affect the terminal air pressure. The pressure reserve of the air supply source shall be determined through the pressure loss calculation. For example, if the terminal needs 0.5MPa, after considering the pressure drop of 0.05MPa, the pressure of the air supply source should be set to above 0.55MPa.
