Introduction to ABS Plastic
ABS plastic is a thermoplastic widely used in various fields due to its excellent mechanical properties, processability, and surface glossiness. It has good impact resistance, heat resistance, and chemical corrosion resistance, while being easy to process and shape.
Principle of Vacuum Forming
Vacuum forming is a plastic molding technology, whose basic principle is to heat the plastic sheet to a softened state and then place it above the mold. By using the vacuum system inside the mold, the air inside the mold is extracted to create negative pressure. Under the action of negative pressure, the softened plastic sheet is adsorbed onto the surface of the mold and closely adheres to the shape of the mold. As the plastic cools and solidifies, it ultimately produces plastic products that conform to the shape of the mold.
ABS plastic Vacuum Forming Process
Preparation stage: Select suitable ABS plastic sheets and design and manufacture molds according to the shape and size of the required product.
Heating stage: Place the ABS plastic sheet into the heating device and heat it to an appropriate temperature to soften it and have a certain degree of ductility. The heating temperature and time should be adjusted according to the characteristics of ABS plastic and the requirements of the desired product.
Molding stage: Place the softened ABS plastic sheet above the mold and activate the vacuum system. As the air inside the mold is extracted, the softened plastic sheet is adsorbed onto the surface of the mold and closely adheres to the shape of the mold. At this point, it can be observed that the plastic sheet gradually deforms and fills the contour of the mold.
Cooling stage: After the plastic sheet fully conforms to the shape of the mold, turn off the heating device and start the cooling system. By cooling, the plastic gradually solidifies and maintains a stable shape.
Demoulding stage: After the plastic is completely cured, open the mold and take out the molded product. At this point, the ABS plastic vacuum forming process is completed.
