gas-assisted injection molding process has high requirements on raw materials, which require good flow and thermal stability of raw materials.
First, gas-assisted injection molding process introduction
Gas-assisted injection molding is a kind of injection molding process in which plastic melt is filled in the mold by air flow. The process improves plastic fluidity and fillability by injecting compressed air into the molten plastic to form bubbles for better mold filling.
The process flow of gas-assisted injection molding is similar to that of traditional injection molding, but additional gas-path systems and control parameters are required. At the same time, the gas-assisted injection molding process also has many advantages, such as high production efficiency and good product appearance quality.
Second, the requirements for raw materials for gas-assisted injection molding
Because gas-assisted injection molding requires the injection of air into the molten plastic, the requirements for raw materials are high. Specifically, the raw material requirements for gas-assisted injection molding are as follows:
1. Good liquidity
Gas-assisted injection molding requires the molten plastic to be delivered to the mold cavity through an airway and air injected during the injection molding process. Therefore, the raw material needs to have good fluidity to ensure that the mold cavity can be evenly filled when the gas is injected.
2. Good thermal stability
Gas-assisted injection molding requires the injection of compressed air into the molten plastic, which will heat the plastic to a certain extent. Therefore, the raw material needs to have good thermal stability to ensure that it will not be deformed or scorched due to excessive temperature when injected into the air.
3. Low shrinkage rate
In gas-assisted injection molding, due to the injection of air, the shrinkage rate of the plastic will be lower than that of traditional injection molding. Therefore, it is necessary to consider the shrinkage rate of raw materials when selecting raw materials, so that better molding effects and higher production efficiency can be obtained in the production process.
In summary, gas-assisted injection molding has certain requirements for raw materials, which require raw materials to have good fluidity and thermal stability, and need to consider the shrinkage rate of raw materials. Therefore, the right raw materials need to be selected in the production process of gas-assisted injection molding to ensure product quality and production efficiency.
