1.Materials

Choose hard materials such as PC, ABS or PC + ABS, which can not only enhance the durability and impact resistance of the luggage box, but also effectively prevent water damage. Soft materials luggage boxes are lightweight, but they are often prone to damage.

2.Wheels and handle

Choose a luggage with a four-wheel design, which can ensure a more stable and smooth pulling experience. The handle should be of sufficient length to accommodate users of different heights. At the same time, the handle should be sturdy and durable, and not prone to damage.

3.Locks

Choose luggage with a password lock or TSA (Transportation Security Administration) password lock to effectively prevent luggage theft. For international travel, choosing a TSA password lock is particularly important as it allows customs officers to inspect the luggage without having to break the lock.

4.Internal structure

The interior of the luggage compartment should have multiple independent compartments and zipped bags to facilitate the organization and storage of items. Additionally, there should be fixed straps or ties to secure clothes and prevent them from swaying around.

5.Size

Select a size that meets the airline's boarding requirements. Usually, it is around 20 inches. This way, it is convenient for carrying the luggage for boarding and also maximizes the luggage capacity.

6.Weight

Try to choose luggage made of lightweight materials. The weight of an empty suitcase should be within 4kg for the best result. This not only makes the luggage lighter but also doesn't exceed the luggage weight limit.

 

 

 

 

Ensuring the dimensional accuracy of the plastic part:

The dimensional accuracy of the plastic trolley case directly affects its usage function and appearance quality. A reasonable shrinkage rate can help mould designers more accurately predict the actual size of the plastic part after it is taken out of the mould during the design process, thereby ensuring the dimensional consistency of the final product.

Optimizing mould structure design:

The structure design of the mould, including the type of gate and the layout of the cooling circuit, all affect the shrinkage behavior of the plastic. Reasonable consideration of shrinkage rates helps optimize these structural designs, reduce the shrinkage differences in different parts of the plastic part, and prevent deformation.

Improving production efficiency:

Understanding and applying appropriate shrinkage rates can, to a certain extent, reduce the cost of trial and error and the adjustment time, increase the initial design success rate of moulds, thereby accelerating the product development cycle and enhancing production efficiency.

Reduce costs:

By reasonably setting the shrinkage rate, it is possible to minimize rework, scrap, and customer complaints caused by dimensional deviations of the plastic parts, thereby reducing the overall production costs.

A reasonable shrinkage rate is of vital importance for the design and manufacture of plastic trolley case mould. It not only affects the quality and functionality of the plastic parts, but also influences the economic efficiency and productivity of the production process. Therefore, during the mould design stage, the shrinkage rate of the plastic must be fully considered and accurately estimated.

 

 

The 3D designing process of plastic trolley case mould is one of the important steps in manufacturing plastic trolley case. Through 3D designing, designers can precisely create the molds of the plastic trolley case and optimize and adjust them in the computer to ensure that the final product meets the requirements and has high quality.

First of all, designers need to collect all the necessary information regarding the size, shape and structure of the plastic trolley case. This information can come from customer requirements, market research, or can also be created through creative design by the designers themselves. The designers need to integrate this information into a 3D designing software such as SolidWorks, AutoCAD or CATIA, etc.

Next, the designer begins to create the overall shape of the suitcase. This usually involves sketching the outline and basic structure of the suitcase, determining its size, shape, and internal divisions, etc. The designer needs to take into account the weight, strength, and appearance of the suitcase to ensure that the final product has good performance and appearance.

After creating the basic structure, the designer can start adding details and features, such as zippers, handles, wheels, etc. These details not only enhance the functionality of the luggage box but also increase the visual appeal of the product. The designer can continuously refine the design of the mold by adjusting the size and position of the details.

Finally, designers need to inspect and optimize the 3D designing. They must ensure that the structure of the mould is reasonable, the details are complete, and it meets the requirements of the manufacturing process. Designers can also test the performance and stability of the mould through simulation and modeling to ensure its reliability and durability.

The 3D designing process of plastic trolley case mould is a comprehensive design process that takes into account the product's functionality, performance and appearance. Through careful design and optimization, designers can create high-quality and competitive plastic trolley case mould.

 

 

When choosing the injection channel for plastic trolley case mould, we need to consider multiple factors to ensure the quality and production efficiency of the moulds. The injection channel is the passage through which plastic raw materials flow in the mould, and it directly affects the quality of the molded parts and production efficiency. Therefore, choosing the appropriate injection channel is very important.

We need to consider the mold design and the characteristics of the product. Based on the design and requirements of the trolley case, determine the optimal layout of the injection channel. Generally speaking, the layout of the channel should avoid short channels and long extensions as much as possible to reduce the impact of the channel on the appearance and quality of the product.

Secondly, we need to consider the diameter and length of the flow channel. The diameter and length of the flow channel directly affect the flow speed and uniformity of the material. A too small diameter will increase the resistance of the fluid, while a too large diameter will increase the cost. Therefore, the selection needs to be made based on specific circumstances. The length of the flow channel also needs to be determined according to the size and shape of the product to ensure the uniform flow of the plastic material.

In addition, we also need to consider the number and layout of the flow channels. A reasonable number and layout can effectively enhance the production efficiency of the mold and reduce production costs. Generally, a linear layout should be adopted as much as possible to avoid excessive bending or branching, in order to ensure the uniform flow and filling of the plastic material.

Finally, we also need to consider the selection of materials and the control of costs. Choosing the right materials can enhance the wear resistance and stability of the molds, and extend their service life. At the same time, it is necessary to balance the production cost and quality requirements, and try to control the production cost while ensuring the quality.
