Thin Wall Food Container Injection Plastic Mold
1. What is thin-wall injection molding
Thin-wall injection molding technology is also called thin-wall plastic injection molding technology. There are three definitions of it:
The ratio of flow length to thickness L/T, that is, the ratio of the flow length L from the melt entering the mold to the farthest point of the cavity that the melt must fill to the corresponding average wall thickness T is 100 or 150 or more for thin-wall injection molding;
The thickness of the molded plastic part is less than 1 mm, and the projected area of the plastic part is more than 50 c㎡ for injection molding;
The wall thickness of the molded plastic part is less than 1 mm (or 1.5mm), or t/d (plastic part thickness t, plastic part diameter d, for disc-shaped plastic parts) is less than 0.05 for injection molding is defined as thin-wall injection molding.
It can be seen from this that the critical value of the definition of thin-wall injection molding will also change, and it should be a relative concept.
2. Development prospects of thin-wall injection molding
As a cutting-edge technology in the injection molding industry, thin-wall injection molding technology has attracted much attention in recent years. This technology is based on the injection molding machine. By precisely controlling the mold shape and structure, high-quality products can be efficiently produced under rapid cooling conditions. Its core advantages are efficient production, cost savings, excellent appearance and energy savings. Specifically, ultra-thin-wall injection molding technology can significantly improve production efficiency and realize automated large-scale production; at the same time, compared with traditional injection molding technology, the material use cost can be reduced by about 50%, and the product appearance quality is excellent with very few defects. In addition, this technology can also efficiently use energy and achieve green production.
Looking to the future, ultra-thin-wall injection molding technology will show a development trend of diversified material application, high-speed molding technology and precise injection control. With the increasing market demand for different plastic materials, ultra-thin-wall injection molding technology will continue to expand the scope of material application; at the same time, the development of high-speed molding technology will further improve production efficiency and product quality. In terms of technology, the support of new cooling technology and injection mold technology will become the key to ensure the high precision and efficient production of ultra-thin-wall injection molding technology. In short, ultra-thin-wall injection molding technology will occupy an important position in the injection molding industry with its outstanding advantages and broad development prospects.
