Commonly Available Bending and Stretching Machinery and Their Prices 

I. Overview of Bending and Stretching Machinery 

Bending and stretching machinery is a mechanical device specifically designed for bending metal profiles into specific shapes and curves. It is widely used in various industries, including construction, automotive, aerospace, and shipbuilding. The main function of this equipment is to bend metal profiles according to the required curvature and shape. Depending on different processing needs, bending and stretching machinery can be categorized into CNC roll benders, pipe benders, medium frequency pipe benders, among others. 

II. Classification and Features of Bending and Stretching Machinery 

(i) CNC Roll Bender 

CNC roll benders are high-precision, high-efficiency bending and stretching machinery. They utilize CNC technology to precisely control the bending angle and curvature of metal profiles. Typically, they consist of a host machine, CNC system, electrical system, hydraulic system, etc. Their main features include high precision, fast efficiency, simple operation, and easy maintenance. 

(ii) Pipe Bender 

Pipe benders are specialized equipment designed for bending metal round pipes. They usually employ mechanical or hydraulic transmission methods to form metal round pipes with different diameters. The main features of pipe benders include simple operation, good bending results, and wide applicability. 

(iii) Medium Frequency Pipe Bender 

Medium frequency pipe benders are devices that heat metal tubes using medium frequency current and then bend them through mechanical force. They typically consist of a medium frequency power supply, heating device, and bending device. Their main features include even heating, good bending results, and wide applicability. 

III. Factors Affecting the Price of Bending and Stretching Machinery 

(i) Equipment Type 

The price of different types of bending and stretching machinery varies significantly. Generally speaking, CNC roll benders have higher prices compared to pipe benders and medium frequency pipe benders. Specific prices depend on factors such as equipment specifications, performance, brand, etc. 

(ii) Equipment Specifications 

Equipment specifications also play an important role in determining the price. Larger equipment usually has a higher price because they require more materials and have higher manufacturing costs. Additionally, larger equipment often has higher production capacity, which leads to correspondingly higher prices. 

(iii) Equipment Performance 

Equipment performance is another key factor influencing the price. High-performance equipment usually has a higher price because it provides better processing results and higher production efficiency. For example, CNC roll benders with high precision and efficiency tend to have higher prices. 

(iv) Brand Factor 

Brand is also an important factor affecting the price of bending and stretching machinery. Well-known brands usually have higher prices due to their reputation and popularity in terms of product quality and after-sales service. Moreover, well-known brands often have higher market recognition and competitiveness, leading to correspondingly higher prices. 

IV. Market Price Analysis of Bending and Stretching Machinery 

According to market research, the current market prices of commonly available bending and stretching machinery are as follows: 

(i) CNC Roll Bender 

The price of CNC roll benders generally ranges from hundreds of thousands to millions of yuan. The specific price depends on factors such as equipment specifications, performance, brand, etc. For instance, a CNC roll bender with a length of 3 meters and an accuracy of ±0.1° may cost around 500,000 yuan. 

(ii) Pipe Bender 

The price of pipe benders generally ranges from tens of thousands to hundreds of thousands of yuan. The specific price depends on factors such as equipment specifications, performance, brand, etc. For example, a pipe bender with a length of 1 meter and a bending diameter of 100mm may cost around 100,000 yuan. 

(iii) Medium Frequency Pipe Bender 

The price of medium frequency pipe benders generally ranges from hundreds of thousands to millions of yuan. The specific price depends on factors such as equipment specifications, performance, brand, etc. For instance, a medium frequency pipe bender with a length of 2 meters and a bending diameter of 200mm may cost around 300,000 yuan. 

V. Suggestions for Purchasing Bending and Stretching Machinery 

(i) Define Requirements 

Before purchasing bending and stretching machinery, it's essential to clarify your processing requirements. For example, the specifications, shape, quantity of metal profiles you need to process. Only by defining your requirements can you choose the right type and specification of equipment for your needs. 

(ii) Choose Reputable Manufacturers 

When purchasing bending and stretching machinery, opt for equipment manufactured by reputable companies. Equipment from reputable manufacturers is usually reliable in quality, stable in performance, and offers excellent after-sales service. Furthermore, reputable manufacturers often have high credibility and reputation in the market, providing better product guarantees. 

(iii) Pay Attention to After-Sales Service 

When buying bending and stretching machinery, consider the after-sales service provided by the manufacturer. For instance, whether free installation and debugging services are offered, whether free training services are provided, whether free maintenance services are available, etc. Choosing a manufacturer with comprehensive after-sales service ensures timely and effective maintenance and care during equipment use, prolonging its lifespan and improving its efficiency. 

(iv) Consider Price Factors Holistically 

When purchasing bending and stretching machinery, take into account various price factors holistically. Although price isn't the only decisive factor, it does play an important role in purchase decisions. When selecting equipment, aim for reasonably priced options within the limits of quality and performance to reduce costs and enhance economic benefits.
