How to Distinguish Mold Grades? Take A Look at The Five Major American Mold Standards

The price of the export mold will be more expensive, but it is expensive because the standard is different. The American Plastics Industry Association (SPIAN-102-78) divides the molds into five categories. Each of these five types of molds has its own requirements, and this classification of molds can only be applied to molds with 400 tons or less of injection molding machines.

mold making

101 type

 

The cycle can be up to 1 million times for high production. The best mold material is made, so the price is very high. The requirements are as follows:

 

(1) detailed mold design information is required.

 

(2) the mold hardness requirement is at least BHN280 (HRC 30).

 

(3) Mie surface (including upper and lower mold) must be at least within the hardness range of BHN450 (48RC). All other accessories such as slide block, inclined top and top press shall use hard tool steel.

 

(4) the ejector must be guided.

 

(5) the sideslip must be equipped with loss plates.

 

(6) a temperature controller may be installed on the upper mold, the lower mold, the slide block or the mold.

 

(7) In the life of the mold, because of the erosion of the cooling water pipeline, the quality of the product will decrease and the injection cycle will be increased. It is suggested that the embedded parts or formwork with cooling water should be treated as anti-erosion.

 

(8) all types of moulds shall be equipped with parting wire clamping mechanism.

 

102 type

 

The cycle can be up to 500 thousand times to 1 million times. The products used for high output are made of good quality mold materials, and the price is high. The requirements are as follows:

 

(1) detailed mold design information is required.

 

(2) the mold hardness requirement is at least BHN280 (HRC30).

 

(3) the surface hardness of the upper and lower mold should be in the range of BHN540 (HRC 48). All other functional accessories should be heat treated.

 

(4) a temperature controller may be installed on the upper die, the lower die, the slide block or the mold.

 

(5) all types of moulds shall be equipped with parting wire clamping mechanism.

 

(6) the possibility or need of the following items depends on the consideration of the final production quantity. It is recommended that the same price list be confirmed.

 

 

103 type

 

The cycle can reach 500 thousand times. The price for medium production is reasonable. The requirements are as follows:

 

(1) detailed mold design information is required.

 

(2) the mold hardness requirement is at least BHN165 (HRC17).

 

(3) the upper and lower mold must have at least BHN280 (HRC30) hardness or above.

 

(4) all other accessories are free to choose.

 

104 type

 

The cycle can reach 100 thousand times. For low output products, the wear resistance of mold materials is not high, and the price is lower than the general reasonable level. The requirements are as follows:

 

(1) mold design information is recommended.

 

(2) the mold embryo can be soft steel or aluminum metal.

 

(3) the upper mold can be aluminum, soft steel or other identifiable materials.

 

(4) all other accessories are free to choose.

 

105 type

 

The cycle should not exceed 500 times. It is used to produce the limited number of the first board, the price is very cheap. The requirements are as follows:

 

The mold structure may be die-casting material, epoxy resin or other material that provides sufficient strength to produce a minimum number of front plates.
