Compared with Injection Molding, What Are the Features of Thermoforming Machines?
Working Principle
Injection molding machine: Injection molding machine injects melted plastic into the mould by heating it, where the plastic cools and solidifies rapidly. The injection molding machine completes the forming process by simultaneously melting the plastic, injecting the plastic, cooling the mould and discharging the finished product.
Thermoforming machine:The thermoforming machine heats thermoplastic sheets or coiled material to make it soften and melt, and then through uses vacuum pressure to adhere the material to the mold surface cooling and forming. Thermoforming machine mainly contains negative pressure adsorption, heating, blowing, cooling and other processes.
Application
Injection molding machine: Injection forming machine isprimarily used for small to medium batch production, as well as high-volume manufacturing of diverse composite materials and components of composites and components. It has the characteristics of high efficiency, high quality, high precision and multi-species production.
Thermoforming machine: Plastic thermoforming machine is mainly used for the production of small and medium batch, isomorphic products, such as disposable plastic tableware, cosmetic packaging shell. While thermoforming is generally slower than injection molding, it achieves excellent dimensional accuracy and superior surface finish.
Difference in Characteristics
Injection molding machine: Injection molding produces high-density parts with, high dimensional accuracy of the product, good surface finish, suitable for moulding complex structure of the product. However, has longer cycle times and requires more floor space.
Thermoforming machine: Thermoforming machine have lower structural density, dimensional accuracy has a certain tolerance, but because of the fast forming speed, can be mass production. At the same time, Due to lower capital investment, ease of operation, and minimal impact on product quality consistency, so it is widely used in some industries.
Main Features of Thermoforming Machine
Thermoforming plastic products are manufactured by heating and processing plastic sheets or films. Compared to traditional injection molding and extrusion molding, thermoforming has the following characteristics:
1. Fast moulding speed: Thermoforming processes heated plastic sheets, the moulding speed is faster and suitable for mass production.
2. Low cost: Thermoforming has significantly lower equipment and material costs than injection or extrusion molding,, thermoforming requires lower cost of equipment and material, suitable for small scale production.
3. Light weight: Thermoformed products have a lighter weight, suitable for occasions requiring lightweight materials.
4. Easy processing: Thermoformed products are easy to process, The products can be easily cut, drilled, or otherwise post-processed.
With the continuous development of technology, Thermoforming applications continue to expand. In the future, thermoforming products will be lighter, more environmentally friendly, energy saving, but also will have higher strength and durability. In addition, thermoforming machine will be more diversified, and enabling production of diverse products for various industrial applications.
