With the strengthening of the degree of design and manufacturing of moulds and the realization of new moulds, the quality of moulds has received more and more attention. No matter from which aspect, many things have been gradually replaced by plastics in the life of the present era. No matter where the products produced by the plastic mould factory are produced, great attention has been paid to the quality problems. Any quality problems may lead to cracking, sticking, deformation and flashing of the products, big head problem and so on.

Plastic mold factory product quality includes the following aspects:.
⑴ Service life: Under the premise of ensuring the quality of the product, the number of working cycles that the mold can complete or the number of parts produced.
⑵ Product quality: product size stability, conformity, product surface finish, product material utilization rate, etc.
(3) The use and maintenance of the mold: whether it is the most convenient to use, easy to demould, and the production auxiliary time is as short as possible.

The basic way to improve the quality of the plastic mold factory: the design of the mold is the most important step to improve the quality of the mold. many factors need to be taken into account, including the selection of mold materials, the usability and safety of the mold structure, the manufacturing process of the plastic mold factory is also an important part of ensuring the quality of the mold, and the processing method and precision in the mold manufacturing process will also affect the service life of the mold, surface strengthening of the main injection mold forming parts of the mold is carried out to improve the surface wear resistance of the mold parts, so as to better improve the mold quality. The correct use and maintenance of the mold is also a major factor in improving the mold quality. For example, the installation and debugging method of the mold should be appropriate. In the case of hot runner, the power supply wiring should be correct, the cooling water circuit should meet the design requirements, and the mold should be injection molding machine and die casting machine in production, the parameters of the press shall meet the design requirements, etc.
In the packaging industry, injection molding process more and more attention, the reason is that people use multi-layer mold, which is a hot runner technology progress, through the use of thin-walled injection molding process, can save the cost of raw materials, other special processes such as die marking and multi-component technology, but also to reduce process steps, improve production and improve efficiency has played a positive role.
Plastic packaging materials, especially in the field of food industry, because of its light weight and good durability, has made a great contribution to improving our living standards today. In addition, it is hard to imagine that the products produced by large industrialization should be distributed to all parts of the world without packaging materials. Therefore, on the whole, in the past few years, the whole plastic packaging market, mainly deep-drawn packaging plastic film has been rapid growth, in which injection molding packaging materials, such as boxes or cups, are on the rise and gradually replace thermoformed packaging materials.

From this point, the following trends can be inferred:.
Higher material costs and additional emissions costs encourage the use of lightweight packaging materials.
The requirements for the performance of packaging materials are getting higher and higher. Today's good packaging materials should have many functions, such as good writability, anti-accidental opening and accurate portion distribution.
Due to the globalization of the processing and sales of packaging materials, the production of packaging materials has increased rapidly. As a result, multi-layer cavity molds have been widely used.
This development has an impact not only on production, but also on the product itself, and while increased productivity and reduced product weight have been priorities, other issues have also arisen, such as consumer protection and text marking.
According to the requirements of comfort and consumer protection, it can be realized by a corresponding safety lock. In order to increase the strength of the edge part, fastening ribs can be added. This measure can improve the comprehensive performance of the material. If it is a thermoforming material, it is impossible to achieve this effect. In addition, polypropylene with good transparency can exert optical properties, and printing links can be omitted by die marking.
