In order to better dredge the circulation of materials, make better use of inventory, solve the quality problems of purchased parts in time, ensure smooth production, prevent the loss of materials, reduce the inventory cost of materials, improve the efficiency of materials, and prevent the phenomenon of shutdown, material backlog and influence on production; At the same time, give full play to the role of material control. In view of this, this department formulates the work content and responsibility scope of material control. Scope of work: tracking and coordination of purchased parts and self-made parts. Work basis: the assembly department provides weekly production plan and executable daily production plan (the work is carried out according to the material demand plan). The purpose of the "three noes" principle is: don't want material, don't want material; Stay, stay; Work content: 1. According to the weekly production plan provided by the four departments and the material demand plan, the production materials are analyzed, calculated and predicted (establishing a platform for information sharing in the local area network, conducting multi-party digital communication and follow-up through data and color management, and telephone mail and one-on-one direct follow-up are also essential). Follow up according to the arrival information confirmed by purchasing and suppliers and the actual arrival situation of the warehouse. Under the condition of ensuring the execution of the weekly production plan, feedback it to the assembly department three days in advance, communicate with the workshop one day in advance to confirm the material preparation plan, and notify the warehouse to prepare materials. Second, the coordination and communication between abnormal feeding and production management, procurement, quality control, injection molding assembly and other departments ensures that abnormal materials are handled without stopping or waiting, and most of them go through warehousing procedures on the premise of timely selection and flow into the next working procedure to ensure the quality meets the standard. Therefore, we must keep active vigilance against material shortage, which requires material control to have a complete understanding of each order BOM and material demand plan, and fully understand the abnormal points of the company's key material feeding status. Third, control the orderly warehousing of incoming materials. On the premise of ensuring no hoarding and accumulation of materials, and on the premise of timely and effective supply of materials in the workshop, we will properly and orderly control the warehousing of a large number of materials, notify the procurement and suppliers to coordinate and communicate, ensure that there is enough space in the warehousing, and truly and effectively play the role of a transfer station. Four. Digest inventory in time, transform production surplus, and prevent unnecessary production of invalid inventory. The most important thing in order follow-up is to prevent inexplicable inventory. At the same time, due to the cancellation of orders, surplus accumulation and excessive delivery by suppliers, it can be transferred to new orders or replenishment in time and effectively, saving procurement costs, preventing unreasonable expansion of warehouses caused by blind production and procurement, effectively and pertinently controlling inventory in this follow-up way, and finally achieving economic rationality. 5. For abnormal materials, some material analysis and calculation methods, such as material turnover rate and material turnover days, are adopted, and some common parts adopt the practical operation method of safe inventory, but the premise is that it cannot cause inventory. 6. Verify the accuracy of warehouse inventory data, especially the purchased materials in the weekly plan. Seven. Analysis of reasons for delay: the manufacturer's delivery records and key follow-up measures for key materials should be followed up, and the time point and time period for follow-up should be set. For emergency materials, it is necessary to establish the way of on-site delivery, and take special treatment methods for special materials to play the role of "fire fighting". VIII. Define the steps of expediting 1. Using BOM to establish the material preparation of batch materials, the shortage of materials is clearly displayed. 2. Start expediting at the set time. 3. Grasp the actual situation and coordinate procurement, materials, production management and warehousing. 4. The most effective emergency material is on-site urging. 5. Established the usual interpersonal relationship with the cooperative factory. In addition, if there are opportunities and conditions, do not hesitate to set up fixed-point reminders for third-party manufacturers of key materials. The material controller should take a proactive attitude and coordinate the communication among production management, procurement, quality control, warehouses, workshops and even suppliers.
