In the fiercely competitive manufacturing environment, reasonably and effectively reducing the processing cost of injection molds is of crucial importance for injection mold processing factories. This can not only significantly enhance the factory’s economic benefits and strengthen its profitability in the market but also effectively lower product prices, thereby improving the product’s market competitiveness and winning a broader market share for the enterprise. The following will elaborate in detail on how to achieve a reasonable reduction in the processing cost of injection molds from three key dimensions: mold selection, processing technology, and management methods.
Reasonable Selection of Injection Molds
Before the production of plastic products officially commences, carefully selecting and designing reasonable injection molds is the most fundamental and effective way to reduce production costs. The structural design of the mold serves as the cornerstone of the entire production process, playing a decisive role in the quality and cost of the products. Different mold structural designs impose different requirements on the products.
An excellent mold takes into full consideration various factors such as the molding characteristics, dimensional accuracy, and demolding convenience of the products during the design phase. It boasts a high yield rate, minimizing the generation of defective products during the production process. Moreover, a well-designed mold can effectively control the amount of waste produced, reducing the loss of raw materials. For example, by optimizing the design of the mold’s runner system, the plastic melt can fill the cavity more evenly and smoothly, reducing the occurrence of defective products due to insufficient or excessive filling, thus naturally lowering production costs.
Adopt Reasonable Mold Processing Technologies
For the same plastic products, different processing technologies will result in significant differences in the types and amounts of raw materials required. Therefore, based on the characteristic requirements of the products and under the premise of ensuring that the product quality meets the standards, actively improving processing technologies is an effective way to reduce production costs.
On the one hand, optimize and adjust the processing parameters. For instance, reasonably control the injection pressure, injection speed, holding time, and mold temperature of the injection molding machine. By precisely adjusting these parameters, not only can the quality stability of the products be improved and the defect rate reduced, but also energy consumption and raw material waste can be decreased. On the other hand, actively explore and apply new processing technologies and methods. For example, the use of hot runner technology can reduce the plastic residue in the runners and improve the utilization rate of raw materials; the adoption of gas-assisted injection molding technology can reduce the weight of the products while ensuring their quality, thereby reducing the amount of raw materials used.
Implement Scientific and Reasonable Management Methods
Implementing scientific and reasonable management methods during the processing of injection molds is a key link in reducing costs and improving efficiency. Strengthen cost accounting and establish a comprehensive and detailed cost management system to strictly control all aspects of production, supply, sales, and finance.
Break down all cost items in the production cost, such as raw materials, auxiliary materials, fuels, power, wages, manufacturing expenses, and administrative expenses, into the unit product cost. By establishing detailed cost ledgers, monitor and analyze the expenditure of each cost item in real-time, promptly identify the reasons for abnormal cost fluctuations, and take corresponding measures for adjustment. For example, through the analysis of raw material procurement costs, optimize procurement channels and select suppliers with higher cost-effectiveness to reduce raw material procurement prices; through the analysis of energy consumption during the production process, adopt energy-saving measures to improve energy utilization efficiency and reduce energy costs.
At the same time, pay attention to reducing unnecessary waste in each link. In the production link, strengthen on-site production management, standardize operation procedures, improve equipment utilization and production efficiency, and reduce downtime and defective products caused by equipment failures and improper operations. In the material management link, reasonably plan inventory to avoid overstocking of raw materials and finished products and reduce inventory costs. Through scientific and reasonable material storage management, ensure the quality and safety of materials and reduce losses caused by material damage and deterioration.
In conclusion, reasonably reducing the processing cost of injection molds requires a comprehensive approach from multiple aspects such as mold selection, processing technology, and management methods to form a systematic and effective cost control system. Only in this way can injection mold processing factories stand invincible in the fierce market competition and achieve sustainable development.
