What is DFM and its importance?
From the future development of the mold industry, how to produce “zero” defective products with low cost and high efficiency has been the continuous pursuit of the industry. Based on the reality, we analyze the actual situation of China's injection mold design and processing at this stage, and determine that all aspects from design to production can be affected by adverse factors, resulting in low level of injection mold production, it is difficult to launch high quality to meet customer needs. High quality injection molds. In view of this situation, the focus should be on DFM technology, which is one of the key technologies of concurrent engineering. It can be effectively applied to the design and processing of injection molds, and can penetrate into the design process, processing process and other links. Comprehensive evaluation, analysis and optimization of injection mold design and processing, and put forward feasible suggestions for improving product quality, shortening cycle and reducing production cost, further improving injection mold design and processing plan, and creating conditions for producing high quality injection molds. . From this point of view, the effective application of DFM technology in the injection mold industry is very meaningful.
I. Overview of DFM technology
DFM is one of the key technologies of concurrent engineering. The core idea is to consider the functional and performance requirements in product design, while considering the possibility of manufacturing, high efficiency and economy, so as to shorten the cycle and reduce the cost under the premise of product quality. the goal of. Its general approach is to interpret the product as a set of features, and to analyze the features that may cause manufacturing problems, and then propose improved design comments .
Second, the application of DFM technology in the injection mold industry
For a long time, the mold industry has been responsible for converting the products designed by upstream customers into molds to produce products that meet customer and market needs. In order to be able to do this, the company needs to connect with the technical departments, product design departments and R&D teams of upstream customers to communicate technical issues. At the same time, in order to ensure that the injection molds designed and manufactured can meet the needs of users. At the same time as the original requirements, reduce the production cost of the enterprise and reduce the ineffective labor.
Based on this, high-tech manufacturing enterprises generally engaged in the design, production and production of injection molds tend to focus on the evaluation and improvement of product design, mold structure, processing and production, in order to launch high-quality products. To this end, the specific work is to collect the relevant information of the injection molds required by the customers from the marketing department in the initial stage. On this basis, the evaluation, review and research of the injection mold project are carried out. This process is DFM analysis. Usually, senior technicians are responsible for researching customer data. According to the company's work flow, the content involved is researched and evaluated item by item. From the aspects of plastic characteristics, product features, mold structure, processing and manufacturing equipment matching, etc. Experts will review and other forms. On the basis of division of labor and cooperation, a special person is responsible for completing DFM, forming a professional report, referring to the report and communicating with customers, finally determining the best design plan and launching the production of injection molds.
(1) Application of DFM activities in product design
Carrying out DFM activities in product design enables the company to participate in product design evaluation, discuss with the customer about the design of injection mold products, and timely point out the shortcomings of product design, so as to optimize product design, this process can also let The company has a deeper and more accurate understanding of the customer's product design intent, and in the subsequent production can be strictly in accordance with the customer's intentions, and ultimately produce customer-satisfied injection molds. In addition, a good DFM activity can also promote the agreement between the two parties before the injection mold project is opened, so as to effectively solve the problems or contradictions in product design, related technologies, production standards, etc., so as to develop the injection mold. Production to avoid unnecessary disputes.
(II) Application of DFM technology in injection mold design
From the actual situation of the injection mold project implemented by the injection mold enterprise, it is determined that the application of DFM technology in the various aspects of the design and production of the injection mold can be used to analyze and evaluate the design, processing and production of the injection mold. And optimize, so as to point out the shortcomings in time, so that relevant staff can deal with problems in time, improve the feasibility of injection mold design and processing solutions, create conditions for the production of high-quality injection molds, in order to enable DFM technology to be produced in injection molds. In the full play of the role, it is best to have a dedicated person responsible for DFM work, and contact with colleagues in the mold design, processing and production, to obtain relevant information, on this basis in accordance with relevant standards for injection mold design and processing and manufacturing links analysis and evaluation And optimization, providing feedback for mold design, processing and production, so that relevant staff can optimize the injection mold solution, creating conditions for the production of good injection molds .
Third, the application of DFM technology in the injection mold industry needs attention
After the above analysis, it is determined that the application level of the injection mold at this stage has been greatly improved, and it is necessary to ensure the high quality of the injection mold produced. To truly do this, companies that undertake injection mold projects should pay attention to the scientific and rational application of DFM technology to evaluate, analyze and optimize the design and processing of injection molds.
