Detailed explanation of treadmill belt and its joint process

As people's living standards improve, more and more people begin to pay attention to their health. Among them, treadmills, as a convenient sports equipment, are loved by more and more people. However, during the use of treadmills, the material, characteristics, manufacturing process and joint heat-sealing process of the belt are also worthy of our attention. This article will explain these aspects in detail to help everyone better understand the relevant knowledge of treadmill belts.

1. Material of treadmill belt

The main materials of treadmill belts are PVC, nylon, PU, ​​etc. Treadmill belts of different materials have different performances, as follows:

1. PVC (polyvinyl chloride): PVC is a common plastic material with good wear resistance, aging resistance and waterproofness. However, PVC material has poor elasticity and is easy to deform after long-term use, affecting the use effect.

2. Nylon: Nylon is a high-strength, high-toughness synthetic fiber material with good wear resistance, tensile resistance and aging resistance. Nylon treadmill belts have good elasticity and long service life, but the price is relatively high.

3. PU (polyurethane): PU is a polymer compound with good wear resistance, tensile resistance and aging resistance. Compared with PVC and nylon, PU treadmill belts have better elasticity and are not easy to deform.

2. Characteristics of treadmill belts

The characteristics of treadmill belts are their excellent performance and comfortable use experience. Specifically manifested in the following aspects:

Wear resistance: The treadmill belt needs to withstand long-term use and friction, so good wear resistance is its basic requirement. High-quality treadmill belts can ensure longer service life and reduce the frequency of replacement.
Tensile resistance: During the use of the treadmill, the running belt needs to bear the weight of the human body and the impact force during exercise, so good tensile resistance is its important feature. High-quality treadmill belts can maintain good flatness during exercise and avoid discomfort caused by deformation of the running belt.
Comfort: The treadmill belt has a large sports usage rate, so comfort has a great impact on its use experience. High-quality treadmill belts can improve the user's sports experience.

3. Manufacturing process of treadmill belts

The manufacturing process of treadmill belts is mainly divided into two types: injection molding and extrusion molding.

Injection molding: Injection molding is to inject molten plastic material into the mold, and obtain the desired shape of the product after cooling and shaping. Injection molding has the advantages of high production efficiency and low cost, but it is difficult to achieve for complex running belt structures.
Extrusion molding: Extrusion molding is to extrude the heated plastic material through the extruder through the mold, and obtain the desired shape of the product after cooling and shaping. Extrusion molding is more suitable for running belts with complex structures, but the production efficiency is relatively low.

4. Joint heat sealing process of treadmill belt

The joint heat sealing process of treadmill belt mainly connects two running belts together through heat sealing equipment to make them a whole. The quality of joint heat sealing process directly affects the use effect and service life of the running belt. The common joint heat sealing at present is high-frequency heat sealing process:

High-frequency heat sealing refers to the use of high-frequency current to make the running belt molecules generate oscillation and heat, so that they combine and melt together. High-frequency heat sealing has the advantages of high bonding strength, good durability and beautiful appearance.

Summary: As a convenient sports equipment, the material, characteristics, manufacturing process and joint heat sealing process of the treadmill belt are all key factors affecting its performance and use experience. Understanding this knowledge will help us choose a suitable treadmill and get a better exercise experience during use.
