Production management system for sand casting enterprise

Abstract

The invention discloses a production management system for a sand casting enterprise. The production management system for the sand casting enterprise comprises a sales order module, a smelting module, a post-processing module, a logistics module and the like. The sales order module is responsible for performing standardization setting on clients and orders, a casting process analog module performs process design on casting parts required by the orders, the casting parts are guided into a producing process, a mold production module designs a production operation instructive order, and the production operation instructive order instructs the fabrication of a mold. A sand form manufacturing module operates a sand form mold to generate a sand form production plan. A smelting pouring module executes a pouring production plan to automatically generate reports by a total quantity control model method. The post-processing module sets a post-processing procedure according to requirements to form inspection reports. A purchase transportation module performs purchasing according to the orders and logistics arrangement of chemical components, post-processing, machining, transportation and the like of set clients. By means of the ERP production management system for the sand casting enterprise, according to production management features of the sand casting process, defects of existing management loopholes can be overcome, production costs are lowered, and the production efficiency is increased.

Description

Technical field [0001] The invention relates to the field of management software, in particular to a production management system and a management method for sand casting enterprises. Background technique [0002] The characteristic of the sand casting industry is that the production workshop occupies a large area and belongs to an order-type production enterprise. It has high requirements for production link control. Moreover, the involved procedures are complicated. The same raw materials adopt different procedures and processes, and the chemical composition of the casting products produced Mechanical properties, surface roughness and crystal phase characteristics are different. [0003] The casting production process involves many instruments and equipment, and the control of the production process is often prone to quality problems, resulting in an increase in the scrap rate and delays in delivery. How to perform lean control on the production process and deliver on time is a p...

AI Technical Summary

Problems solved by technology

[0007] The existing sand casting production enterprises are in the initial stage of the supply chain of the machinery industry. Therefore, compared with the terminal equipment production enterprises, the profit margin of the foundry enterprises is low, the management control is chaotic, and the technical force is weak, which makes the whole industry seem to have the following problems: (1) The production management process has a high degree of intersection, and the links between various production links are not smooth

(2) The process technology cannot directly guide and control the production, and the actual production operation is separated from the process design

(3) Lack of production process tracking management

(4) Cost control is extensive, and most costs are estimated prices, which cannot be tracked and calculated

(5) High dependence on manual management, repeated management and quality problems due to human factors

(6) The production capacity is greatly affected by the quality, and the subsequent processing speed has obvious obstacles to the front process

(7) The quality of casting products is unstable, and repeated repairs and repeated inspections cause many problems

(8) The production environment is harsh, the turnover of personnel is high, and the risk of human resources continues to increase
