Hello everyone, my name is little LiM. Last time we talked about how to improve the stability of large size laser selective melting equipment during technology development. In this period, we will continue to discuss this topic from the design and development of equipment and production process control, and see how LiM laser does it.

Establish a sound product system, focus on R & D and quality system control

In view of the company to add variety material manufacturing equipment research and development, research and development cycle, the characteristics of many varieties and small batch production, based on different models this paper summarizes the general requirements of products, from based on the functional demands, security, economy, reliability requirements, and other aspects to control and balance the diversification demand and standardization requirements. Establish perfect research and development of project management and decision making mechanism, in the process of project research and development and production, analyze the organization of internal and external environmental factors, through the establishment of related party list of needs and expectations, develop risk measures, planning, design and development process input, output, change, trial production, experiment and key process control. Strictly implement ISO9001, ISO14001, ISO45001 related systems and GJB9001C military standard system requirements.

Using a platform and modular device development model, to ensure that small batch also has high quality

For modular design of equipment, it is necessary to understand the structure of existing products, construct BOM and assembly relationship (e.g. Equipment can be disassembled into by molding chamber, shaft, circulation purification module module shop, powder, powder conveying and recycling, atmosphere system module composition and so on), by analyzing the strength of the correlation relationship between the components, the strong relationship between the components to be integrated, reduce the number of parts and form module, and design a standard interface between the modules (such as: The drive and control method of forming shaft, the migration and innovation of powder spreading module and atmosphere module, the unified design of circulation purification module, powder conveying and recycling). Adopting the design concept of platform, according to the key factor of additive equipment "molding size", it is divided into small, medium and large series. According to the key factor "number of optical systems", it is divided into single, double and multi-series. Finally, through the synthesis of "molding size" and "number of optical systems" two factors, the formation of LiM-X150, X260, X400, X650, X400H, X650H, X800 and other series of models of equipment installed in the same assembly line. The platform design can not only meet customers' customized requirements, achieve cost and quality control, but also improve equipment reliability and reduce maintenance costs.

Implement lean production to improve consistency and stability of product quality

Special leading group was set up to implement lean production way, clear related business management responsibilities and tasks, lean production work plan, including production management department, production department, technical department, project department, quality department, purchasing department, lean production organization, clear to improve the responsibility of the head. The goal of LEAN improvement is continuous improvement, and the concept of lean improvement is instilled in all employees. Improve the efficiency of taking and counting by strengthening 6S management in the workshop; Conduct regular investigation of potential risks to reduce safety accidents; Improve the reward and punishment system, encourage employees to put forward reasonable suggestions and other measures, multi-pronged to ensure the consistency and stability of product production, quality, environment, so as to ensure the long-term trouble-free work of equipment.

Through the deployment and use of digital systems, enhance the collaboration ability of design, development and production processes

Use the ERP and OA information system uniformly deployed by the whole company to support the business of finance, purchase, sales and stock, production management and process approval. At the same time, the PDM system is deployed to support R&D services, and the interconnection and integration between the systems have been realized. In the process of informationization tool use, will be the long-term development of knowledge and experience accumulated in the standardization, standardization, and routing, form data information center (server database), and Shared with all project to participate in the department, through the research and development of PDM and ERP system to make BOM information sharing in supply chain, such as to reduce the overall cost of supply chain. Through the design data management of PDM system, ensure the consistency and security of R&D data, and timely manage engineering changes to ensure the efficient collaboration between R&D and production.

   

That's it for this episode, and we'll share more about how to improve the stability of large scale laser selective melting equipment next time. I am Xiao LiM, follow me, more technology sharing welcome everyone to participate.
