Production process

1) ESI (Earlier Supplier Involvement):

This stage is mainly about the product between customers and suppliers. The main purpose of technical discussions on design and mold development is to allow suppliers to clearly understand the design intentions and accuracy requirements of product designers, and also to allow product designers to better understand mold production capabilities and product process performance, thereby making a more reasonable design.

2) Quotation: including the price of the mold, the life of the mold, the turnover process, the required tonnage of the machine and the delivery time of the mold. (A more detailed quotation should include information such as product size and weight, mold size and weight.)

3) Purchase Order: Issuance of customer orders, deposits, and acceptance of supplier orders.

4) Mold production planning and schedule arrangement (Production Planning and Schedule Arrangement): This stage requires a reply to the customer regarding the specific delivery date of the mold.

5) Mold design (Design): The design software that may be used includes Pro/Engineer, UG, Solidworks, AutoCAD, CATIA, etc.

6) Purchasing materials

7) Mold processing (Machining): The processes involved include turning, milling (milling), heat treatment, grinding, CNC, EDM, WEDM, and JIG GRINGING , laser engraving, polishing, etc.

8) Mold Assembly (Assembly)

9) Mold Trial Run (Trial Run)

10) Sample Evaluation Report (SER)

< p>11) Sample Evaluation Report Approval (SER Approval)

Causes of loss

1) Problems with the materials of the main working parts of the mold, Improper material selection. The material properties are poor and not wear-resistant; the mold steel is unrefined and has a large number of smelting defects; the convex and concave molds and the forging process are imperfect, leaving hidden dangers of heat treatment.

2) Mold structure design problem, the die structure is unreasonable. The slender punch is not designed with a reinforcement device, the discharge port is not smooth, and accumulation occurs. Excessive discharge force causes the punch to bear increased alternating loads, etc.

3) The mold making process is imperfect, mainly manifested in the poor internal quality of the convex and concave die forging blanks, and problems with the heat treatment technology and process, resulting in the convex and concave dies not being quenched through, with soft spots and poor hardness. all. Sometimes micro-cracks or even cracking occur, grinding and polishing are not in place, and the surface roughness value is too large.

4) No lubrication or lubrication but poor effect,
