1, Economy of material selection
Material cost is an important component of the total cost of molds. Reasonable selection of mold materials is the key to cost control in injection mold design. On the one hand, it is necessary to consider the physical properties, chemical stability, and thermal conductivity of the material to ensure that the mold can meet production needs; On the other hand, it is also necessary to balance the price and supply stability of materials to achieve maximum cost-effectiveness.
High performance mold steels such as H13 and P20, although expensive, can significantly improve the service life of molds due to their excellent heat fatigue resistance and wear resistance. In the long run, it is beneficial to reduce the cost sharing of molds per unit product. Meanwhile, with the increasing awareness of environmental protection, choosing materials that are recyclable or have low environmental impact is also an economic consideration for companies to fulfill their social responsibility and enhance their brand image.
2, Economic feasibility of structural design
The design of mold structure directly affects the manufacturing cost, processing difficulty, and production efficiency of the mold. In design, the principle of "simplicity rather than simplicity" should be followed, striving to simplify the mold structure and reduce unnecessary complex features while meeting the functional requirements of the product, in order to reduce processing difficulty and manufacturing costs.
For example, by optimizing the parting surface design and reducing the use of complex mechanisms such as sliders and inclined tops, the difficulty of mold processing and assembly costs can be reduced. In addition, adopting standardized and modular design concepts not only facilitates the rapid manufacturing and maintenance of molds, but also improves the universality and interchangeability of molds, further reducing mold costs.
3, Economic efficiency of processing
Improving the processing efficiency of molds is an important way to reduce production costs. In the mold design stage, the ability of processing equipment and the optimization of processing paths should be fully considered to reduce processing time and material waste.
Using advanced CAD/CAM software for mold design can achieve 3D modeling and automatic programming of molds, improving design efficiency and machining accuracy. At the same time, combined with CNC machining technology, precision machining and efficient production of molds can be achieved, reducing manual operations and errors, and lowering processing costs.
4, Economic viability of mold lifespan
Mold lifespan is one of the key factors affecting mold costs. In mold design, reasonable structural design and material selection should be used to improve the durability and fatigue resistance of the mold, and extend its service life.
For example, optimizing the cooling system design to ensure effective heat dissipation of the mold during operation, avoiding mold deformation and damage caused by overheating. In addition, surface treatment techniques such as nitriding and carburizing can improve the hardness and wear resistance of the mold surface, and extend the service life of the mold.
5, Economic viability of maintainability
The maintainability of molds is of great significance for reducing production costs and improving production efficiency. In mold design, attention should be paid to the ease of disassembly and maintenance of the mold, which facilitates daily maintenance and troubleshooting of the mold.
For example, using standardized and universal fasteners and connectors facilitates rapid disassembly and assembly of molds. At the same time, necessary inspection holes and maintenance channels should be reserved in the mold design to facilitate cleaning, inspection, and maintenance of the interior of the mold, reducing downtime and production costs caused by mold failures.
6, Case Study: Application of Economic Considerations in Injection Mold Design
Taking the design of an injection mold for a certain automotive interior part as an example, the mold needs to meet the requirements of high precision, high output, and long service life. In the design, the designer used high-performance mold steel and combined advanced CAD/CAM software and CNC machining technology to achieve precision manufacturing and efficient production of the mold. Meanwhile, by optimizing the design of the mold structure and cooling system, the durability and fatigue resistance of the mold have been improved.
In actual production, the mold has demonstrated excellent performance and stability, not only meeting the high-precision requirements of the product, but also greatly improving production efficiency and reducing production costs. In addition, due to the reasonable design and easy maintenance of the mold, the maintenance cost of the mold has also been effectively controlled.
