the mold industry lays great emphasis on efficiency. Sometime, considering the credit therein, even when business negotiation between the manufacturing and the customers is still under way, the design of molds and even the manufacturing have already started. The materials are essentially used immediately upon being purchased. they only stay for a brief time at the warehouse and taken to be processed or assembled thereafter. The material management, closely connected with processing. is the intermediate stage between mold deisgn and workshop processing. As a system, the management for direct materials should be convenient and in quick response.
