1

Material costs account for approximately. 30%of mold prices.

The cost of material includes: mold core steel+mold frame (S50C)+copper public+standard parts+heat flow channel

Common mold steel: S 136, NAK 80, 2344, 2733, P20, 718, SKD 11 and SKD 61

1 million cycle-quenching S 136, quenching 2344

500,000 cycles-Nak 80, S 136

300,000 cycle-2733, P2020,718

Graphite electrode-40 yuan/kg; copper electrode-80 yuan/kg

The commonly used mold substrate is S50C-10 yuan/kg.

2

Design costs account for 3%-5%of mold costs.

Processing/manufacturing cost: normal processing, numerical control processing, electric spark processing, line cutting, mold polishing, heat treatment, deformation

3

Processing costs usually account for 30%of mold costs.

The length and width of the mold core = product size+30-60 mm, core thickness = product thickness+approximately. 80 mm

Generally, the length and width of the mold seat = on both sides of the size of the mold core+50-120 mm, the thickness of the mold seat is usually twice the mold core.
