How much vacuum degree of vacuum glue filling machine is suitable?

When vacuum filling glue, the vacuum degree is generally required to reach about 10 ^-3~10 ^-4 Pa. The vacuum degree within this range can effectively prevent oxygen, moisture and other impurities in the air from entering the glue, thereby ensuring the bonding quality and bonding strength.

If the vacuum degree is too high, it may cause adverse effects on the product, and the negative pressure may explode the product components. If it is too low, it may not meet the vacuum potting standard, which will affect the product quality. However, in actual operation, it is necessary to determine the appropriate vacuum degree according to the requirements of specific materials and glue. Standards should not be overly applied. Before the formal large-scale potting production, a small batch of vacuum pouring glue test should be carried out.

What products need vacuum glue?

Vacuum glue filling is a kind of glue filling and packaging process widely used in electronic components, automobiles, aircraft, military equipment and other fields. Its main function is to remove air during the bonding process to prevent oxygen, moisture and other impurities in the air from affecting the bonding performance of the glue. There are no restrictions on the use of the product. Glue manufacturers suggest that vacuum glue can be used for glue filling whenever the product manufacturing process needs.

The following are some common products that require vacuum filling:

1. Electronic components: for example, semiconductor devices, capacitors, inductors and other electronic components.

2. Automobile: Manufacturing of brake, steering gear, transmission and other parts in the automobile industry.

3. Aircraft: Various assemblies in the aviation industry, such as aircraft seats, fuselage shells, etc.

4. Military equipment: all kinds of tanks, ships, aircraft and other military equipment manufacturing components.

5. Other: such as medical equipment, chemical equipment, spacecraft and other industries need to ensure material sealing and rust resistance components.

How much product can vacuum glue be poured?

The size of the vacuum glue filling is related to the model and specification of the equipment. Generally speaking, the small vacuum glue filling machine can fill the product with smaller size, while the large vacuum glue filling machine can be used for larger size products. The more common vacuum glue machine models can be used for filling smaller size products, such as electronic components in the range of a few millimeters to tens of centimeters, auto parts, etc. For larger products, such as fuselage, large rubber products, etc., it is necessary to use larger specifications of equipment for vacuum filling. The equipment specifications of different manufacturers will also vary slightly, so the size and quality requirements of the product should be carefully considered before selection.
