Dispensing Process Uses and Requirements

Uses of the dispensing process:

Dispensing process is a commonly used precision coating technique, whereby the glue is precisely applied to a specified location by controlling the flow of the glue. Dispensing process is widely used in electronics, automotive, medical, aerospace and other fields, with the following main uses:

1. Electronics manufacturing:

Protective coating on PCB boards before welding to prevent component surface oxidation and pollution.

Chip fixation, conductivity, isolation and other operations to ensure that the connection of electronic products is solid and excellent electrical properties.

Sealing, waterproofing, dustproofing, etc. on the shell or components of electronic products to improve the reliability and durability of the products.

2. Automotive parts manufacturing:

In the production of automotive parts, the dispensing process is used for sealing, fixing, waterproofing, shock absorption and so on.

For example, in the automotive lamp assembly, the use of dispensing technology for sealing treatment, to prevent water vapour from entering the interior of the lamps and lanterns to affect the service life of the lamps and lanterns.

3. Medical device manufacturing:

Some key components in medical devices need to be precisely sealed and fixed, dispensing process can meet these needs.

In single-use medical devices, dispensing is used to ensure that the product is sealed and hygienic.

4. Aerospace:

In the aerospace sector, dispensing processes are widely used in the manufacture and repair of aircraft, satellites and other vehicles.

Dispensing process is used to connect, seal and insulate aerospace materials to ensure a strong structure and stable performance of the vehicle.

Requirements of dispensing process:

The quality and effect of the dispensing process is affected by a variety of factors, need to meet certain requirements to ensure its stability and reliability:

1. Accurate control system:

Dispensing system needs to have accurate and stable control system, can accurately control the flow and position of the glue to ensure the accuracy and consistency of the glue.

2. Suitable glue selection:

According to different application scenarios and requirements to choose the right type of glue and performance, to ensure that the adhesion of the glue, weather resistance and environmental protection to meet the requirements.

3. Appropriate glue pressure and speed:

Adjust the glue pressure and speed to control the flow and moulding of the glue, and ensure that the glue is coated evenly and stably.

4. Good process flow and operation specification:

Set up reasonable process flow and operation specification, standardise the operation steps and requirements of operators to ensure that each process meets the standard requirements.

5. Strict quality inspection and control:

Establish a perfect quality testing mechanism to test and verify the coated glue, detect and deal with quality problems in time, and improve the qualified rate of the products.

6. Operator's skills and experience:

The dispensing process needs to be operated by professionally trained operators who have good skills and experience and are familiar with the dispensing equipment and process flow.

7. Environmental and safety requirements:

The dispensing process needs to be carried out in a clean and tidy production environment to avoid contamination such as dust and foreign matter affecting the coating effect of the glue.

At the same time, it is necessary to comply with safety regulations to ensure the safety of operators and equipment to reduce the occurrence of accidents.

Conclusion

Dispensing process, as an important precision coating technology, has a wide range of applications and important role. Through reasonable setting of process parameters, selection of suitable glue, strict control of quality requirements and other measures, the stability and effect of dispensing process can be improved to meet the product needs and quality requirements of different industries. Continuous improvement and upgrading of the technical level and management level of the dispensing process will help to improve production efficiency and product quality, and enhance the competitiveness and market share of enterprises.
