Thermoforming is a manufacturing process used to shape plastic sheets into various custom design products. It involves heating a plastic sheet until it becomes pliable, then using a mold or a vacuum to form it into the desired custom shape.
Thermoforming and vacuum forming are both processes used to shape plastic sheets into specific forms. However, there are some differences between the two techniques:
Thermoforming is a versatile process that is widely used in industries such as packaging, automotive, aerospace, and medical. It offers advantages such as cost-effectiveness, quick turnaround times, and the ability to produce complex shapes with high precision.

The competition between China's machine tool companies and international machine tool companies is inevitable under the global economic environment. What the domestic machine tool companies have to do is to give full play to their existing advantages and strive to upgrade their products against the market gap. The biggest advantage of the Chinese machine tool industry is that it is close to the machine-consumption market in China, and the industry can achieve technological upgrading in the tide of market development.
The Chinese machine tool industry will strive to adapt to economic growth and have the technological advantages required by users of machine tools around the world - this includes high precision, high efficiency, high output rate, and high stability. On this basis, we can deepen the international competitiveness of China's machine tool industry.
Of course, in order to further guide the market demand, the Chinese machine tool industry must continue to devote itself to strengthening the technical strength. It is believed that in the near future, local Chinese companies will be able to provide the market with higher-performance machine tool products.
1. Process: In thermoforming, a plastic sheet is heated until it becomes pliable, and then it is pressed against a mold using pressure or a vacuum. Vacuum forming, on the other hand, relies solely on the use of a vacuum to draw the heated plastic sheet onto the mold.
2. Mold complexity: Thermoforming is typically used for more complex shapes and intricate molds, as it allows for greater detail and precision. Vacuum forming, on the other hand, is better suited for simpler shapes and molds that do not require as much detail.
3. Material thickness: Thermoforming is often used for thicker plastic sheets, typically ranging from 0.030 to 0.250 inches in thickness. Vacuum forming is more commonly used for thinner plastic sheets, typically ranging from 0.005 to 0.060 inches in thickness.
4. Production volume: Thermoforming is generally more suitable for high-volume production due to its faster cycle times and ability to handle larger sheets of plastic. Vacuum forming is better suited for low to medium volume production, as it has slower cycle times and is limited by the size of the vacuum forming machine.
5. Cost: Thermoforming typically requires more expensive equipment and molds, making it a more costly process compared to vacuum forming. Vacuum forming, on the other hand, is a more cost-effective option for smaller production runs or prototypes.
Overall, thermoforming is a more advanced and versatile process that offers greater precision and complexity, while vacuum forming is a simpler and more cost-effective option for less complex shapes and smaller production volumes.
CNC technology pushes the machine tool industry to higher performance products
The links between the machine tool industry in China and Japan are getting closer and closer, which is evidenced by the development of JMTBA's member companies in China – there are currently a total of 63 JMTBA members operating in China (at least There are business establishments. This number was 55 in 2000 and it is still growing steadily in the following years.
