Mold Standards in America

The price of export mold is more expensive due to the different standards. The mold is divided into five categories by SPIAN-102-78. Five types of mold have different requirements and standards of themselves. This kind of mold classification only applies to the mold of injection molding machine with 400 tons or less.

101 mold
The cycle can reach one million times which is suitable for products of extremely high volume production. Choose the best mold material to make, so the price is very expensive. Below is the required standards:

• Detailed mold design information is required.
• Hardness of mold base reach at least BHN280(HRC30).
• The mold surface(upper die and lower die) must be at least in the BHN450(48RC) hardness range. All other accessories, such as the slider, lifter etc., should use hard tool steel.
• The ejector must have a guide.
• (The side slider must be equipped with a loss plate.
• A temperature controller should be installed on the upper and lower die, slider or where possible on the mold.
• In the die life, due to the erosion of the cooling water pipe, the product quality is reduced and the injection cycle is increased. The embedded parts or templates with cooling water transportation are recommended to do erosion protection treatment.
• All mold of this type shall be equipped with parting line and clamping mechanism

102 mold
The cycle can reach between half a million and one million times, which is suitable for products of high volume production. Choose good quality mold material to make, so the price is expensive. Below is the required standards:

• Detailed mold design information is required.
• Hardness of mold base reach at least BHN280(HRC30).
• The surface of upper die and lower die must be at least in the BHN540 (HRC48) hardness range.All other functional parts should be heat treated.
• A temperature controller should be installed on the upper and lower die, slider or where possible on the mold.
• All mold of this type shall be equipped with parting line and clamping mechanism
• Following items need or not, which depends on the consideration of the quantity of final production. Suggest for these project is that doing a confirmed quotation.

103 mold
The cycle can reach half a million times, which is suitable for the products of medium volume production. Cost is reasonable. Below is the required standards:

• Detailed mold design information is required.
• Hardness of mold base reach at least BHN165(HRC17).
• The surface of upper die and lower die must be at least in the BHN280(HRC30) hardness or higher.
• Freedom choice for all other accessories.

104 mold
The cycle can reach one hundred thousand times,which is suitable for the products of low volume production. The wear resistance of die material is not high, the price is lower than the general reasonable level. Below is the required standards:

• Mold design information is suggested.
• The mold base can be soft steel or aluminum.
• The upper mold can be aluminum metal, soft steel or other identified material.
• Freedom choice for all other accessories.

105 mold
Cycle no more than 500 times, which is used to produce a limited number of the first board. The price is very cheap.Below is the required standards:
Mold structure may be die-casting material, epoxy resin or other materials that can provide sufficient strength to produce a minimum number of first plates.
