Many purchaser want to choose a good metal spinning supplier, but they don't know which companies is suit your metal spun products. This article introduces the basic information of different spinning companies to help you select a right suppliers.

1. Metal spinning levels of various countries

Metal spinning, as a traditional process, has been developed in many countries for many years. However, the technical levels of spinning vary from country to country. The countries with relatively leading global spinning levels include Germany, Spain, the United States and Japan. Although China has only been developing numerical control spinning for a relatively short period of time, it has developed very rapidly in the nearly two decades since joining global trade. At present, Chinese metal spinning factories are the largest in scale, specializing in hub spinning and three-wheel spinning. Chinese CNC spinning equipment manufacturers have also successively developed powerful double-roller, hub spinning, three-roller flowing forming and other excellent cnc spinning equipment.Many countries such as Vietnam and India are constantly purchasing equipment from China because the equipment made in China has a significant cost advantage.

Although India and Vietnam have low labor and land costs, the current spinning technology is mostly manual spinning, and it is mainly used in the lighting and tableware industries. This metal spun products don’t need accuracy, and the thickness is thin.

2. Why choose a metal Spinning supplier in China

As you know, The manufacturing industry in China is of a very large scale, Not only in the metal spinning industry, but also in the supply chain used for spinning products, such as planar laser, three-dimensional laser, heat treatment, stamping, drawing, polishing, powder coating, and oxidation. The manufacturing density in China is extremely high, The communication and transportation of the entire product are extremely convenient.This advantage is irreplaceable by the manufacturing industries of other countries.

3. Why the advantages of the USA and Europe in high-end industries can't be replaced

The precision and performance of the metal spinning equipment used in factories in Europe and the United States are still more advanced than other countries. Meanwhile, their spinning technology has been accumulated for a longer time and there is less turnover of technical personnel. Most companies in China were established not long ago, have a short lifespan and high staff turnover. Often, in high-end fields, the competition for spun products lies in the performance of the equipment and the level of craftsmanship. These are the weak points of Chinese spinning companies.

In addition, the original R&D companies of the upstream metal spinning products are located in Europe and the United States. It is more convenient for them to choose local spinning companies for communication. Data adjustment is faster, and the sample and freight cycles are short, Of course, the manufacturing costs of companies in Europe and the United States are high.

4. The distribution and trends of metal spinning suppliers

The manufacturing of some precision and high-end spun products has gradually shifted from the United States, Europe and Japan to China. At present, all industries in China are developing rapidly. A European purchaser came to China ten years ago. Most of the spinning in China was still done by hand. Ten years later, he was amazed at the speed of progress of Chinese spinning companies when he come again. Both the R&D and design capabilities, as well as the spinning production equipment and testing equipment in the factory, have been greatly enhanced.

Due to the reasons of land and labor costs, a large number of products produced by spinning have gradually shifted to India and Vietnam, such as the lighting industry and the tableware industry. These spun products can meet the customers' demands by hand spinning.

5. Classification of metal spinning factory

When you visit a spinning company, the first thing you can examine is their equipment. Based on the equipment, you can determine the fields they manufacture in.

1) Manual spinning lathe

Factories mainly engaged in manual spinning mainly produce lighting fixtures, tableware and hotel decoration. Hand spinning can’t spin the products that need control the accuracy. When the order quantity is large, the production capacity is not as fast as that of CNC spinning.

2) Light-duty CNC spinning machine

Light-duty CNC spinning machines refer to those machines that can only spin thin spinning products, such as aluminum thickness is less than 2mm, steel thicknes is less than 1.5mm, stainless steel thickness is less than 1mm. The existence of light duty CNC spinning machines is mainly to replace manual spinners, to enhance the production efficiency of spinning and reduce labor costs. The power of the main shaft motor is generally less than 10KW.

3) Heavy - duty CNC spinning machine

Heavy-duty spinning machines are mainly designed to solve the spinning forming problems of thick materials and special materials for aviation and other industries in the market. For instance, the core components of some machinery and equipment, high-precision parts, these spun parts require tensile strength, hardness, precision. The power of the main shaft motor is generally more than 20KW.

6. What are the characteristics of a precision CNC spinning company

Many companies that need to purchase high-precision spinning products often make a mistake. They usually place orders with factories that produce manual spinning and ligh-duty spinning. Due to the limitations of equipment and technology, they often can’t provide qualified spinning samples even after a long time of production. The precision metal spinning companies often has the following characteristics, you can make a judgment from the following aspects.

1) Advanced spinning equipment

The spinning machines are all very neat and clean, and there are a lot of daily records of the spinning process archives and parameters.

2) Standardization management

Mold, roller, tool management is very standardized, the maintenance and labels are clear.

3) Various blank materials

There are a wide variety of raw materials for spinning. Due to the different mechanical property requirements for raw materials in the high-end field, spinning plants come into contact with many types of raw materials, such as Special nickel, high-temperature alloys, and aviation aluminum, which are very common.

4) Inspection tool

All spun products are thin-walled parts. Traditional calipers cannot detect spun products. When a caliper applies a little force to hold a spun product, it will cause it to deform and its size will also change accordingly.

In order to inspect spun product better, it better to choose the go-no go gauge to inspect the diameter and height. So precision CNC metal spinning companies will have many inspection tool to check the spun products in quality control room.

8. Why choose a metal spinning in Dongguan

Dongguan is the world's manufacturing capital. Compared with other manufacturing cities in China, manufacturing in Dongguan is more concentrated. For instance, in the hardware manufacturing industry, various processing industries are gathered in one town of Dongguan, such as wire cutting, milling, turning, grinding, sheet metal, spraying, oxidation, polishing, spinning, five-axis laser, and heat treatment. Basically, corresponding factories can be found within 5 kilometers to supply. The entire operation and communication are highly efficient. In addition, all kinds of equipment in Dongguan are of a relatively high precision type. The overall level of factory management and quality control in Dongguan is higher compared to other factories in China. Dongguan is more suitable for making high-precision customized spun metal products.
