Mold is an important process foundation in manufacturing industry, accounting for a large proportion in China's manufacturing industry. With the development of the Chinese economy and the improvement of people's living standards, the demand for various products continues to increase, which is both an opportunity and a challenge for the mold industry.
1、 Overview of mold industry
Various molds and tools used in the mold industry for injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make molded objects, which is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the formed material. Known as the 'Mother of Industry'.
A tool that transforms a blank into a specific shape and size of a workpiece under external force. Widely used in punching, forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as in the molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape, and using a contour shape with a cutting edge can cause the blank to separate (punch) according to the contour line shape. The application of inner cavity shape can enable the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a convex mold and a concave mold), which can be separated or combined. Remove the parts when separated, and inject the blank into the mold cavity to form when closed. Molds are precision tools with complex shapes that can withstand the swelling force of raw materials. They have high requirements for structural strength, stiffness, surface hardness, surface roughness, and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
2、 Market development status of mould industry
In addition to the mold itself, it also requires a mold base, mold frame, mold core, and a device for ejecting the workpiece, which are generally made into universal types. Mold enterprises need to become bigger and more refined. They need to determine product positioning and market positioning based on market demand, technology, funding, equipment, and other conditions. These practices are particularly worth learning and referencing for small mold enterprises, and focus on gradually forming their own technological and product advantages. Therefore, Chinese mold companies must actively strive to learn from the experience of these advanced foreign enterprises in order to achieve better development in the future.
There are many types of molds, which can be classified into different types according to different classification methods. According to the different materials formed, molds can be divided into metal molds and non-metal molds. Metal molds are divided into casting molds (non-ferrous metal die-casting, steel casting) and forging molds, while non-metal molds are also divided into plastic molds and inorganic non-metal molds. According to the different materials of the molds themselves, molds can be divided into sand molds, metal molds, vacuum molds, paraffin molds, and so on.
Intelligent molds are stamping molds and die-casting molds with sensing and temperature control functions. Injection molds manufactured by intelligent control methods such as temperature control, injection parameters, and flow state inside the mold are all intelligent molds. Compared with traditional molds, intelligent molds have obvious advantages such as high technological content, high product added value, long service life, wide application range, and large market space. High precision, sharpness are the most obvious features of intelligent molds. If effectively used in traditional industries, intelligent molds will greatly improve the production efficiency of existing manufacturing industries, and industrial transformation and upgrading work can be better carried out. The market size of China's intelligent mold industry reached 5.53 billion yuan in 2020 and 5.94 billion yuan in 2021.
The market size of China's mold industry in 2022 is about 346.773 billion yuan, a year-on-year increase of 12.6%. From the perspective of market structure, with the steady progress of automobile lightweighting in recent years and the continuous development of China's plastic industry, especially modern new material industries such as engineering plastics, the plastic mold market has developed rapidly and has become the largest sub category of molds in China, accounting for about 45%, followed by stamping molds and casting molds, accounting for about 37% and 9%, respectively.
Molds can not only meet the domestic market demand, but also be exported in large quantities to the international market, and the industry's import and export trade gap is also expanding year by year. Specifically, in recent years, the overall import amount of molds in China has shown a downward trend, while the overall export amount has shown an upward trend. In 2022, the import amount of molds in China was 711 million US dollars, a year-on-year decrease of 17.6%; The export amount was 6.142 billion US dollars, a year-on-year increase of 5.7%. From the perspective of export distribution, in the amount of mold exports in China in 2022,
The top three regions in terms of proportion are the United States, Vietnam, and Germany, accounting for 10.73%, 7.4%, and 6.55% respectively.
With the advancement of technology, new manufacturing techniques and processing technologies continue to emerge, providing more possibilities for the mold industry. For example, the application of new technologies such as digital manufacturing, 3D printing, and intelligent manufacturing will make mold manufacturing more efficient, precise, and personalized. With the increasing complexity of product appearance and internal structure, the requirements for precision and complexity of molds are also becoming higher and higher. In the future, precision and complex molds will become mainstream, and the demand for high-precision and high-efficiency mold manufacturing equipment will continue to increase.
