Over the past 30 years, China's packaging industry has experienced a development process from scratch and from small to large. Today, China is the world's second largest packaging country with an annual industrial output value of more than 1.2 trillion yuan. The output of packaging products ranks among the top in the world. In the 42 industrial sectors of the national economy, the total output value of the packaging industry has risen from the second to the twelfth in the 1980s, becoming an important industry in the national economy.
In the packaging industry, injection molding processes are increasingly favored by people. The reason is that people use multi-layer molds. This is an advancement in hot runner technology. By using a thin-wall injection molding process, the cost of raw materials can be saved. Other special processes, such as stamping and multi-component technology, have also played a positive role in reducing process steps, increasing throughput and benefit.
Plastic packaging materials, especially in the food industry, have contributed greatly to improving our living standards today due to their light weight and durability. In addition, it is unimaginable to distribute large-scale industrial products to all parts of the world without packaging materials. Therefore, on the whole, in the past few years, the entire plastic packaging market, mainly deep-drawing plastic film, has grown rapidly. Among them, injection molding packaging materials, such as boxes or cups, are on the rise and gradually replace thermoforming packaging materials.
However, at present, the manufacturing process conditions of domestic packaging molds (packaging machines, filling machines, molds on filling and sealing machines) are uneven, which seriously affects the precision and quality of the molds. For example, in the precision heat treatment process, the difference in mold materials makes it difficult for domestic molds to compete with foreign products in terms of appearance quality and service life. In foreign countries, special mold materials are used, which are superior in mechanical properties, wear resistance, corrosion resistance and polishing brightness. The level of standardization needs to be improved. China's mold standardization work started late, and the production, sales, promotion and application of standard parts were relatively backward.
The demand for mold talents is far greater than the dilemma of supply. We must make persistent efforts to accelerate the pace of structural adjustment of mold products. The overall development direction will still be to achieve the development speed of large, precise, complex, long-life molds and mold standard parts higher than the overall speed of the industry; continue to expand the proportion of plastic molds and injection molds; expand the number of professional mold manufacturers and ability. Increase investment to strengthen innovation capabilities. It is necessary for the backbone enterprises to complete the complete set of equipment from roughing and heat treatment of molds to various finishing, finishing, quality control and monitoring. General enterprises should also have CNC machining equipment to realize fully automatic processing of mold manufacturing. Promoting joint restructuring between mold companies should become the general trend. This is mainly due to the fact that a considerable part of the current mold enterprises are private enterprises, and objectively there are problems in the introduction of advanced molding technology and equipment, which undoubtedly intensifies competition in the middle and low-end markets. The development of overseas markets needs to be deepened. In Australia, for example, the country's demand for stamping dies is rising, and China can use its technological and equipment advantages in this area to further explore the international market.
