Moulds are classified by SPIAN-102-78 into 5 categories, each of which has different specification.

Model 101

It is used in high-production products, for it has a long lifetime with 1,000,000 times. The material of 101 must be high quality. The specification of 101 is as fellows:

(1)     Detailed design of mould

(2)     The hardness of mould base is HRC30 at least

(3)     The surface hardness is HRC48 at least

(4)     Loss plate on the side slide is needed

(5)     There must be a temperature controller on the mould

(6)     In order to avoid corrosion, a cooling inserts is needed

(7)     A split line clamping mechanism

Model102

Its lifetime is around 5,00,000 to 1,000,000 times.

(1)     Detailed design of mould

(2)     The hardness of mould base is HRC30 at least

(3)     The surface hardness is HRC48 at least

(4)     There must be a temperature controller on the mould

(5)     A split line clamping mechanism

Model 103

The lifetime of 103 is 500,000 times.

(1)     Detailed design of mould

(2)     The hardness of mould base is HRC17 at least

(3)     The patrix and counterdie hardness is HRC30 at least

(4)     Other inserts is not compelling

Mould 104

The lifetime of 104 is 100,000 times. And it can be used in low-production products.

The specification:

(1)  The mould desigh is suggested

(2)  The material of mould base could be soft copper or aluminum

(3)  The material of patrix: alminum, mild steel or other identified material

Model 105

Lifetime: less than 500 times

Material: die casting material, epoxy resin
