SPI-SPE plastic mold classifications and standard

The mold category is divided into the following categories according to the American SPI-SPE standard.

SPI-SPE standard Class 101 Injection Mold

Cycles 1,000,000 shots or more, extremely high production mold

1. Detailed mold design required.
2. The minimum hardness of mold base material is 280BN. (DME #2 steel / 4140 steel)
3. The inner mold cavity/core steel must be as hard as 48~50HRC. All other details, such as sub-inserts, slides, heel blocks, gibs, wedge blocks, lifters, etc. should also be of hardened tool steels.
4. The ejection board must have guide posts.
5. Slides must have wear plates.
6. If possible, the mold cavity & core and slides should have temperature control.
7. For all cooling, it is recommended to use electroless nickel or 420 stainless steel plates. This can prevent rust and clean up garbage.
8. Need parting line locks for 101 class molds.

SPI-SPE standard Class 102 Plastic Mold

Cycles 1,000,000 shots or more, extremely high production mold

1. Detailed mold design required.
2. The hardness of the mold base material is at least 280BHN. (DME #2 steel / 4140 steel)
3. The inner mold cavity/core steel should be as hard as 48~52HRC at least, and the other useful mold components should also be treated in the same way.
4. It is recommended to use parting line locks for 102 class molds.
5. The following items may or may not be required. It depends on the final production quantity. It is recommended to check if the following items are used when make a plastic mold quotation.
A. Ejector plate guide post.
B. Slide ware plates.
C. Electroplating water line.
D. Electroplating mold cavity/core. 

SPI-SPE Class 103 Injection Mold

Cycles less than 500,000 shots, medium production mold

1. Detailed mold design required.
2. The minimum hardness of mold base material is 165BHN. (DME #1 steel / 1040 steel)
3. The inner mold cavity/core steel is P20 (28~32HRC) or high hardness (36~38HRC).
4. The rest of the requirements depend on the need. 

Class 104 Injection Mold

Cycles less than 100,000 shots, small production molds

1. The mold design is required.
2. The mold base material P20 (28~32HRC) can be made of mild steel or aluminum. (1040 steel)
3. The inner mold cavity/core can be made of aluminum, mild steel or other approved metals.
