1.The styles of plastic suitcases are usually divided into two types: hard-shell and soft-shell. Hard-shell luggage boxes are usually made of durable ABS plastic or PC material, which have good waterproof and moisture-proof properties and can effectively protect the contents inside the luggage. Soft-shell suitcases are usually made of soft materials such as nylon or polyester fibers, which are lightweight and easy to fold, and are more suitable for long trips.

2.The styles of plastic suitcase include different sizes of boxes. Small suitcases are suitable for short trips or as carry-on luggage, while large suitcases are suitable for long trips or for carrying more items. In addition, there are also multi-functional suitcases, such as those with internal compartments and zipped bags, which are convenient for organizing the luggage.

3.The designs of plastic suitcase also feature many personalized features. Some suitcase have rotating wheels or silent wheels, which are convenient for dragging and moving; some also come with password locks or fingerprint unlocks to enhance security. At the same time, some brands have launched limited editions or collaboration styles to meet the fashion needs of different consumers.

4.The styles of plastic suitcase are diverse and abundant. Consumers can choose the suitable style according to their own needs and preferences. At the same time, whether it is choosing a hard-shell or soft-shell, small-sized or large-sized, they can all provide convenient and practical functions for travelers during their trips. We hope that every traveler can find the most suitable style when choosing plastic suitcase and enjoy the pleasure of traveling happily and easily.

 

 

 

 

The use of a hot runner system for plastic suitcase mould is a widely recognized excellent choice. This is because the hot runner system can provide a more stable and efficient solution for mould injection molding. Compared to the traditional cold runner system, the hot runner system has many advantages and benefits in the plastic injection molding process.

The hot runner system can enhance the efficiency of mold injection molding. The traditional cold runner system requires additional time for preheating and cooling, which increases the production cycle and cost. However, the hot runner system can quickly and uniformly heat the plastic material and reduces the cooling time, thereby significantly improving the production efficiency and speed.

The hot runner system can enhance the quality and consistency of the products. Since the hot runner system can more accurately control and regulate the temperature and fluidity of the plastic material, it can better avoid problems such as bubbles, deformation, and defects in the products, and produce higher-quality and more consistent plastic products.

The hot runner system can also reduce waste and save materials. Since the hot runner system can inject plastic materials into the mold more accurately and reduces the generation of waste and defective products, it can significantly decrease material loss during the production process, save costs, and be more environmentally friendly.

The hot runner system can also enhance the lifespan and stability of the mold. Since the hot runner system can reduce the pressure and friction of plastic materials in the mold, it can significantly extend the lifespan of the mold, reduce maintenance and replacement costs, and maintain the stability and reliability of the mold.

 

 

A good exhaust system has a significant impact on both the plastic suitcase mould and the products. Therefore, in order to avoid troubles caused by poor exhaust later on, we should pay great attention to the exhaust system of the plastic suitcase mould.

Understanding the importance of exhaust: During the injection molding process, molten plastic entering the mold cavity needs to completely remove the air inside the cavity, including the air in the cavity and the injection system, the water vapor produced by the evaporation of water in the plastic raw materials at high temperatures, the gases produced by the decomposition of plastic at high temperatures, and the gases produced by the volatilization or chemical reactions of certain additives in the plastic, etc. Reasonably setting up exhaust grooves can reduce parameters such as injection pressure, injection time, holding time and mould closing pressure, thereby improving production efficiency, reducing production costs and reducing the energy consumption of the machine.

Understand the effects of poor exhaust: Poor exhaust can lead to problems such as product scorching, overflow, silver streaks, welding marks and bubbles. Therefore, when designing the mold, these issues must be taken into account, and corresponding measures should be taken to prevent their occurrence.

Understanding the types and methods of exhaust: Exhaust is divided into exhaust slots at the sealing position and air introduction slots avoiding voids. The length and width of the exhaust slots are relatively flexible, and the height should not exceed the plastic overhang value. The exhaust slots should be preferably opened at the front mould, and specific situations should be analyzed on a case-by-case basis. In addition, there are various types and methods of exhaust such as exhaust between mould cores and nylon pins, exhaust at the parting surface, exhaust at the runner position, exhaust with insert pins, exhaust at large collision surfaces, exhaust by push pins, exhaust of the flow channel, exhaust of the assembly structure, exhaust of the venting steel, and exhaust at the garbage position.

Adhering to the principle of exhaust design: When designing the exhaust system, certain principles should be followed. For instance, the position and size of the exhaust channels should be determined based on the type and fluidity of the plastic. At the same time, it is necessary to avoid excessive exhaust channels that may cause material leakage. Additionally, factors such as the mould structure and processing technology should also be taken into consideration.
