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 process performance of products, 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, etc. )
3) Purchase orders: deliver customer orders, store and accept supplier orders.
4) Mold production plan and progress: At this stage, we need to reply to the customer according to the specific delivery date of the mold.
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 engraving and polishing.
8) mold assembly
9) Trial operation of the mould
10) model evaluation report (SER)
1) Approve the model evaluation report (SER approval)

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 forging blank is not perfect, and there are hidden dangers in heat treatment.
2) The mold structure design problem, the mold structure is unreasonable. The slender punch is not designed with reinforcement device, and the discharge port is not smooth, resulting in accumulation. Excessive discharge force intensifies the alternating load of the punch.
3) The forming process is not perfect, which is mainly manifested in the poor internal quality of the forging blank of the male and female dies and the problems in the heat treatment technology and process, resulting in incomplete quenching of the male and female dies, soft spots and uneven hardness. Sometimes there will be micro-cracks or even cracks, grinding and polishing are not in place, and the surface roughness is too large.
4) No lubrication or lubrication but poor effect,
