Although the downward pressure on the economy in the first half of the year has increased, with the implementation of various national policies for steady growth, the business environment of the company will be further improved this year. It is expected that the operation of the Chinese construction machinery industry will stabilise and recover. In 2014, the sales revenue of the entire industry could increase by about 8%. %.
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.

According to the China Construction Machinery Industry Association, sales of major construction machinery products in China in the first seven months of this year increased by 0.88% year-on-year. In general, the development trend of China's construction machinery industry is steady at present. Although its overall sales volume and operating income show a negative growth trend, this is by no means the industry is declining, but is experiencing a painful process from rapid growth to stable growth. period". In the future, the pull of the country’s steady growth policy will gradually emerge, the overall situation of the industry will improve, and the trend of stable and sustainable development will emerge. In the long run, the future construction machinery industry is still a sunrise industry. Looking at the history of world construction machinery development, China is still in a period of growth.
At the same time, industry experts also emphasized that China's equipment manufacturing industry as a whole is large and not strong. With the shift of middle and low-end product processing and manufacturing industries to Southeast Asia and other developing countries, and the “re-industrialization†strategy of western developed countries leading to the “backflow†of high-end manufacturing companies, the current status of China's equipment manufacturing industry is facing challenges. .
It is reported that in the future, the development path of China's construction machinery industry will be divided into two phases. The first phase will be to enter the first phalanx of global construction machinery. The concrete manifestation is the stable improvement of scale, the continuous improvement of quality performance, and the obvious optimization of product structure. The potential for development is significant.
The second stage is to become a powerful country in the world of construction machinery. The concrete manifestation is the steady development of scale, the overall improvement of quality performance, the overall optimization of product structure, and the potential for sustainable development.
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.
