Is there a shortage of supply in the precision mold market?

The mold industry has a broad prospect, and the precision mold market is in short supply. However, the proportion of high, medium and low-end molds produced by my country's mold industry is extremely unbalanced, which is very unfavorable to the development of my country's mold industry. There is an urgent need to speed up structural adjustment and develop the high-end market segment to keep pace with the international market.

Is 3D printing a replacement for traditional mold making?

In addition, in terms of product design, the principles and practices of traditional injection mold manufacturing have a history of more than a century, and the industry has thoroughly studied them. For example, the draft angle must be greater than or equal to 5 degrees to meet the requirements of most aluminum molds. 3D printing molds to inject plastic parts is a challenge, and extra care is needed for the number and placement of plastic mold thimbles. 3D printed molds (especially high injection temperatures) are somewhat more flexible in terms of increasing cavity wall thickness and reducing pressure. The gate design is also different and tunnel and point gates should be avoided. Direct gate, fan gate, wing gate should be increased to 3 times the normal size. The flow direction of the polymer in the printing mold should be in line with the 3D printing line to avoid high filling caused by stickiness and low pressure. The cooling system can increase the life of the mold to a certain extent, but it will not significantly reduce the cycle times of the printed mold, because the heat dissipation ability of 3D printed molds is not as good as that of aluminum or steel molds.

Five opportunities and three challenges for the plastic products industry

Because of its excellent performance, plastic products are widely used in real estate, automobiles, household appliances, consumption, packaging, consumer electronics, medical equipment and other fields, and their role in promoting the construction of the national economy and improving the material and cultural life of the people is increasingly apparent. In recent years, the Chinese government has formulated a series of industrial policies to support and promote the development of the plastic products industry in the direction of high performance, high quality and environmental protection.

Precautions for the heating of injection molds

　In order to make the injection mold process reflect the exquisite workpiece, we will heat the injection mold, which can not only improve the precision height of the injection mold, but also improve the quality and precision of the workpiece. It is mainly divided into four links, namely forging process, preparatory heat treatment, quenching and tempering, and stress relief annealing. Below are the points to note for each section.

What should be paid attention to when choosing plastic additives

　Plastic additives not only make the polymer easy to process, but also make up for the shortcomings of the polymer itself to a large extent, such as improving the performance of the product and prolonging the service life. Therefore, it is no exaggeration to say that without the cooperation of processing aids, there will be no development of the plastics industry.

Injection mold technology and its development trend

Mold is the basic process equipment in industrial production, and it is also an indispensable tool for the development and realization of less cutting technology. In electronics, automobiles, motors, electrical appliances, instruments, home appliances and communications industries, 60% to 80% of the parts and components require mold processing. More molds are used in the production of light industrial products. Therefore, the mold industry has the "mother of all industries". "The reputation.
