Export mold prices will be more expensive, but there are expensive reasons, because the standards are not the same. The American Society of Plastics Industry (SPIAN-102-78) divides molds into five categories. Each of these five types of molds has its own different requirements. This type of mold is only applicable to molds with an injection molding machine of 400 tons or less.
Model 101
Cycles up to 1 million times for extremely high throughput products. The use of the best mold material makes it extremely expensive. The requirements are as follows:
(1) Detailed mold design information is required.
(2) BHN280 (HRC 30) is the minimum required for mold embryo hardness.
(3) The mold surface (including upper and lower molds) must be at least in the BHN450 (48RC) hardness range. All other accessories such as sliders, sloped roofs, pressure tops, etc. should use hard tool steel.
(4) The ejector must be provided with guides.
(5) The side slider must be equipped with a lossy plate.
(6) Mount the temperature controller on the upper mold, lower mold, slider, or mold where possible.
(7) In the life of the die, due to the erosion of the cooling water pipeline, the product quality is degraded and the injection cycle is increased. It is recommended that the insert or template for cooling the water be used for anti-erosion treatment.
(8) All molds of this type should be equipped with split mold clamping mechanism.
Model 102
The cycle can reach 500,000 to 1 million times. For high-volume products, use good quality mold materials, expensive. The requirements are as follows:
(1) Detailed mold design information is required.
(2) BHN280 (HRC30) is the minimum required for the hardness of the mold.
(3) The surface hardness of the upper and lower molds should be in the BHN540 (HRC 48) range. All other functional accessories should be heat treated.
(4) Mount the temperature controller on the upper mold, lower mold, slider, or mold.
(5) All molds of this type must be equipped with split mold clamping mechanism.
(6) The following items may or may not be required depending on the final production quantity. It is recommended that these projects also make a confirmed quotation.
Model 103
The cycle can reach 500,000 times. For the production of the product, the price is reasonable. The requirements are as follows:
(1) Detailed mold design information is required.
(2) BHN165 (HRC17) is required to have a minimum mold mold hardness.
(3) The upper and lower molds must have a minimum hardness of BHN280 (HRC30) or more.
(4) All other accessories are free to choose.
Model 104
The cycle can reach 100,000 times. For low-volume products, mold material wear resistance is not high, the price is lower than the general reasonable level. The requirements are as follows:
(1) It is recommended to have mold design information.
(2) Mold blanks may be mild steel or aluminum metal.
(3) The upper die may be aluminum metal, mild steel or other identifiable material.
(4) All other accessories are free to choose.
Model 105
The cycle does not exceed 500 times. For the limited number of first boards, the price is very cheap. The requirements are as follows:
The mold structure may be die-cast material, epoxy or other material that provides sufficient strength to produce the lowest number of first plates.
