1) ESI (early supplier participation):
This stage is mainly the technical discussion between customers and suppliers on product design and mold development. The main purpose is to let suppliers clearly understand the design intent and precision requirements of product designers, and at the same time let product designers better understand the mold production capacity and product process performance, so as to make more reasonable designs.
2) Quotation: including mold price, mold life, turnover process, tonnage required by the machine, and mold delivery date. A more detailed quotation should include information such as product size and weight, mold size and weight. )
3) Purchase orders: the issuance of customer orders and deposits and the acceptance of supplier orders.
4) Mold production plan and schedule: At this stage, the specific delivery date of the customer's mold needs to be replied.
5) Mold design: The possible design software includes Pro/Engineer, UG, Solidworks, AutoCAD, CATIA, etc.
6) Purchasing materials
7) Machining: The processes involved include turning, gong (milling), heat treatment, grinding, computer gong (CNC), electric spark (EDM), wire cutting (WEDM), fixture grinding, laser lettering and polishing.
8) mold assembly
9) Trial operation of the mold
10) sample evaluation report (SER)
1 1) Template evaluation report approval (SER approval)
Extended data:
Cause of loss
1) Material problem of the main working parts of the mold, improper material selection. Material performance is poor, not wear-resistant; Die steel is not refined and there are many smelting defects; The forging process of punch and die and forging blank is not perfect, and there are hidden dangers of heat treatment.
2) The mold structure design problem, the mold structure is unreasonable. The slender punch is not designed with reinforcement device, and the poor discharge port leads to accumulation, and the excessive discharge force makes the punch bear alternating load.
3) Imperfect die-making process is mainly manifested in poor internal quality of the punch and die forgings, and problems in heat treatment technology and process, which lead to incomplete quenching of the punch and die, soft spots and uneven hardness. Sometimes micro-cracks or even cracks appear, the grinding and polishing are not in place, and the surface roughness value is too large.
4) There is no lubrication or lubrication, but the effect is not good.
