How does a Fully Automatic Blow Molding Machine Handle Different Types of Plastic Materials?

Material Selection
The first step is to select the appropriate plastic material for the desired bottle. Different types of plastic materials have different properties, such as melting point, viscosity, and shrinkage rate, which can affect the final product.

Material Preparation
The selected plastic material is then prepared for the blow moulding process. This involves melting the plastic pellets or granules in a hopper and then transferring them to the extruder.

Extrusion
The extruder is a heated barrel with a rotating screw that melts and mixes the plastic material. The molten plastic is then forced through a die, which shapes it into a hollow tube called a parison.

Moulding
The parison is then clamped between two halves of a mould, which is designed to create the desired shape of the bottle. The mould is cooled to solidify the plastic and then opened to release the finished bottle.

Cooling and Trimming
The newly formed bottle is cooled to ensure its shape is maintained. Once cooled, excess plastic is trimmed off from the top and bottom of the bottle.

Quality Control
The final step is to inspect the bottle for any defects or imperfections. This is done using various quality control measures, such as visual inspection, leak testing, and weight measurement.
