Dimension accuracy:

Ensure that the model's dimensions are precise and error-free, taking into account the needs of actual production and use.

Material properties:

Choose the appropriate plastic material and assign it the correct physical properties to achieve a realistic effect during the later rendering process.

Structural rationality:

When designing, consider the actual structure of the roller suitcase, including internal frames, hinges, drawbars, etc., and ensure that these structures are accurately represented in the model.

Detail handling:

Pay attention to the details on the surface of the roller suitcase, such as textures and patterns, as these will affect the appearance quality and feel of the final product.

Lightweight design:

While ensuring strength, try to reduce the weight of the roller suitcase as much as possible. This not only helps to lower transportation costs but also enhances the user experience.

Mold feasibility:

Considering the subsequent injection molding process, avoid overly complex shapes and structures to prevent increasing the difficulty and cost of mould production.

Color and texture: Select appropriate colors and textures to make the model more realistic.

 

 

 

 

The design of a plastic roller suitcase mould is a very crucial step, and the design of the ejection mechanism is particularly important. The ejection mechanism plays a very significant role in the mould, and its design directly affects the molding quality and production efficiency of the plastic products.

Firstly, the design of the ejection mechanism should be in line with the overall structure and shape of the plastic roller suitcase. Plastic roller suitcase usually come in various shapes and sizes. The design of the ejection mechanism needs to be reasonably formulated and adjusted according to the specific size and shape of the roller suitcase , so as to ensure that the ejection mechanism of the plastic roller suitcase mould can fully match the shape of the roller suitcase, reduce deformation and damage during ejection, and ensure the molding quality.

Secondly, the design of the ejection mechanism should take into account the production efficiency and stability of the roller suitcase. The design of the ejection mechanism should ensure that the ejection speed and force are appropriate, so that plastic products can be ejected from the mould in a timely manner without causing unnecessary damage or pressure to the mould and the products, thereby ensuring the efficiency and stability of production.

Furthermore, the design of the ejection mechanism should take into account the maintenance and upkeep of the mould. The ejection mechanism is usually a part of the mould that is prone to damage and wear. When designing, factors such as service life and maintenance cycle should be considered. Materials and structures that are resistant to wear and corrosion should be selected to ensure that the ejection mechanism can maintain a good working condition and extend the service life of the mould.

 

 

1.Mould material selection: Choose high-quality mould materials, such as pre-hardened steel or stainless steel. These materials have good wear resistance and corrosion resistance, and can maintain the smoothness of the mould surface for a long time.

2.Mould design optimization: Reasonably design the mould structure to avoid stress concentration and deformation. At the same time, adopt precise processing techniques, such as electrical discharge machining (EDM) and CNC machining, to ensure the dimensional accuracy and surface roughness of the mould cavities and cores.

3.Surface treatment technology: The surface of the mould can be polished. Methods such as mechanical polishing, chemical polishing, and electrolytic polishing can be employed. Among them, mechanical polishing is the most commonly used method, which gradually improves the surface smoothness by using different grit sandpapers and diamond polishing pastes.

4.Using additives: By adding appropriate additives to the plastic raw materials, such as lubricants and anti-static agents, the surface properties of plastic products can be improved and surface defects can be reduced.

5.Control of molding process: Properly set the injection molding parameters, such as temperature, pressure, and speed, to avoid scratches or damages on the mould surface. At the same time, regularly maintain and clean the mould to prevent impurities from adhering to the mould surface.

6.Mould temperature control: Through the mould temperature control system (MTS), the mould is uniformly heated or cooled to reduce the deformation of the mould caused by temperature changes, thereby improving the surface smoothness of plastic products by.

In conclusion, achieving high surface finish of plastic roller suitcase mould requires comprehensive consideration of various aspects such as mould material, design, surface treatment, additive usage, process control during molding, and mould temperature management. By implementing these measures, the surface finish of plastic roller suitcase can be effectively improved, thereby enhancing the quality and appearance of plastic products.

 

 

Understand product characteristics

It is necessary to know the dimensions (length, width, height, wall thickness) and weight of the plastic products to be produced.

Select the appropriate model

Based on the extraction direction of the product and the structure of the mould, determine the structural form of the injection molding machine. Common structural forms include vertical, corner, and horizontal injection molding machines. Different structural forms are suitable for different types of products and moulds.

Consider the clamping force

The clamping force is an important parameter of an injection molding machine. It determines whether the machine can withstand the expansion force within the mould cavity, thereby ensuring the stability of the mould. The magnitude of the clamping force needs to be calculated based on the projected area of the product, the ratio of the process length to the wall thickness, the material, and the cavity pressure of the mould.

Matching mold dimensions

The size and shape of the mould directly affect the selection of the injection molding machine. It is necessary to ensure that the dimensions of the mould conform to the specifications of the injection molding machine, especially the spacing of the connecting columns (guide columns), as it determines the overall dimensions of the mold. At the same time, the size of the template also needs to be in accordance with the size requirements for installing and fixing the molding mould.

Consider product accuracy

The accuracy requirements of the product directly influence the selection of the injection molding machine. For example, for engineering plastic products, an injection molding machine with an alloy screw and barrel, as well as a screw with a length-to-diameter ratio (L/D) exceeding 20 times, needs to be chosen to achieve good plasticization standards and meet the requirements.

Understanding the performance parameters of the injection molding machine

Before selecting an injection molding machine, one should refer to the performance parameter values provided in the product user manual by the manufacturer. These parameter values include the maximum injection volume, working accuracy, speed, and product precision level, etc. They determine whether the injection molding machine can meet the molding conditions of the products.

Consult professionals

If you are still unsure about how to choose an injection molding machine, you can consult professional injection molding machine suppliers. They can provide the most suitable injection molding machine solution based on your specific needs.
