The two common types of thermoforming machines are vacuum forming machines and hot melt adhesive machines.
A thermoforming machine is a device that heats plastic sheets or sheets so that they can be formed under certain conditions. It usually consists of two upper and lower heating plates, which can heat the plastic material to a specific temperature and then shape it into the desired shape through pressure and cooling. Thermoforming machines are widely used in the manufacture of packaging, electronics, medical and automotive fields.
At present, there are two main types of thermoforming machines, including vacuum forming machines and hot melt adhesive machines.
1. Vacuum forming machine
A vacuum forming machine is a machine that adsorbs thermoplastic plastic sheets or sheets on the surface of the mold and heats them to a softened state, and then cools them into the desired shape through negative pressure. It usually consists of two upper and lower heating plates, an air pressure system and a vacuum pump. Among them, the heating plate is used to heat the plastic sheet, the air pressure system is used to compress the plastic sheet, and the vacuum pump is used to extract air from the mold to form a vacuum. Vacuum forming machines can be used to make packaging and containers of various shapes, such as boxes, disc packaging, shoe boxes, glasses boxes, etc.
2. Hot Melt Glue Machine
A hot melt glue machine heats and melts hot melt glue particles into liquid, then sprays or applies it to the surface of the desired molding part, and forms the desired shape after cooling. It usually consists of a heating cylinder, a melting chamber, a nozzle, and a pressure device. Among them, the heating cylinder is used to heat and melt the glue particles, the melting chamber is used to store the melted glue liquid, the nozzle is used to spray or apply the melted glue liquid, and the pressure device is used to press the glue liquid so that it can better fit the shape of the molding part. Hot melt glue machines can be used to manufacture electronic devices, automotive parts, and building materials of various shapes.
In short, the choice of thermoforming machine depends on factors such as the shape, size, material, and budget of the desired item. No matter which type of thermoforming machine is chosen, you need to pay attention to its safety and operating specifications, and you should comply with relevant regulations and recommendations when operating.
