What is the difference between vacuum casting process and automatic pressure gel equipment(APG)?

The vacuum casting process and automatic pressure gel equipment are two different methods used in the manufacturing of components, particularly in the realm of polymer or resin-based materials. Here's a breakdown of the key differences between these processes:

Vacuum Casting Process:

Principle: The vacuum casting process involves using a vacuum chamber to remove air and create a low-pressure environment before introducing a liquid resin or polymer material.
Material Flow: The liquid material is poured into a mold, and the vacuum chamber helps remove air bubbles and draw the material into the mold cavities.
Pressure Application: Once the material is in the mold, the vacuum is released, and atmospheric pressure allows the material to flow and fill the mold completely.
Advantages: The vacuum casting process is suitable for producing complex, intricate parts with fine details and undercuts. It allows for excellent reproduction of mold details, minimal air entrapment, and good surface finish.
Automatic Pressure Gel Equipment:

Principle: Automatic pressure gel equipment, also known as resin transfer molding (RTM), uses a closed mold system and applies pressure to inject resin into the mold cavity.
Material Flow: The resin is mixed with a catalyst or hardener and injected into a closed mold cavity using hydraulic or mechanical pressure.
Pressure Application: The closed mold is pressurized using hydraulic or mechanical force to ensure the resin flows throughout the mold and fills all the cavities.
Advantages: Automatic pressure gel equipment is suitable for producing complex parts with consistent dimensions and mechanical properties. It allows for control over the resin-to-fiber ratio, leading to improved strength and stiffness of the final product.
In summary, the key differences between the vacuum casting process and automatic pressure gel equipment lie in the material flow and pressure application methods. Vacuum casting relies on the removal of air and atmospheric pressure to draw the material into the mold, while automatic pressure gel equipment uses controlled pressure to inject resin into a closed mold cavity. Each process has its advantages and is chosen based on the specific requirements of the desired component.

A SET OF VACUUM POURING TANK (ATMOSPHERIC PRESSURE) SYSTEM Vacuum tank technical specifications and uses:

Horizontal tank inner wall size: Φ2000mm×2400mm

Ultimate vacuum: 50Pa (no load, cold state)

No load leakage rate: 50Pa.L/S

Operating temperature: 70 ~ 85℃

Tank surface temperature: ambient temperature +20℃

The casting supervisor adopts pneumatic ball valve for feeding, and can adjust the vacuum casting valve actually needed according to the number of products. The spare flange interface of the casting pipe is reserved for future upgrading.

The pouring tank is horizontal, the door of the tank is swung open on the side, and the tank body is of vacuum pouring tank structure. After the door is closed in place, the tank is clamped.

The vacuum casting process can optimize the casting process, increase the permeability of the material, and finally achieve the effect of reducing the release index of the product.

Lock the can card manually after the can door is closed in place.

The tank body is installed on the ground, and light rail and working trolley (reinforced) are provided in the tank.

The outer surface of the tank is heated by electric heating plate.

The height of the track inside the tank is flush with the track of the transfer trolley outside the tank (self-made by the user of the transfer trolley outside the tank), so as to facilitate the access of the trolley;

Rock wool insulation, stainless steel plate (SUS430) armored processing.

The tank body is provided with other interfaces to meet the technological requirements.
