Split design, reasonable layout and convenient maintenance. â– Boom upgrade: The boom of the HT75W has been changed from the front-mounted type to the side-mounted type, which makes the excavation center of gravity move backwards, greatly improving the stability during excavation work, and also solves the problem of the right front line of sight of the whole machine during walking, and improves the whole machine. Safety factor. At the same time, the arc of the boom is improved, the length is lengthened, the back angle is increased, and the working parameters are close to 9 tons. â– Engineering tires: Super wear-resistant, puncture-proof, tear-proof; withstand the quality of its own and load, maintain its running performance; buffer the shock and vibration received by the vehicle, maintain the stability and smoothness of the vehicle; ensure the reliability of the entire tire Contact with the ground to improve vehicle passability and braking. â– Some parameters: â– Can be equipped with accessories: (This article comes from Hengte excavator)
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.

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.
