Plastic mold grades are divided into grades according to production volume, product accuracy, customer requirements and quotations. Mass production molds, medium production molds, and small production molds.
- 1. Need detailed mold structure drawing.
- 2. The minimum hardness of the mold material is 28 HRC.
- 3. The internal mold steel with glue position must be pre-hardened to 48 ～ 50HRC. Other parts such as row position, pressure lock, and bead should also be hardware.
- 4. The thimble plate must have a mid-care.
- 5. To install straight lock or oblique lock.
- 6. For all waterways, it is recommended to use electroless nickel or 420 stainless steel as a template. This can prevent rust and clean up garbage.
- 7. The upper mold, lower mold and row position should have temperature control.
- 8. There should be wear-resistant blocks in the row position and pressure lock.
Mass production of molds
- 1. Need detailed mold structure drawing.
- 2. The minimum hardness of the mold material is 28 HRC.
- 3. The internal mold steel with glue position should be hard to a minimum of 48-52HRC, and the remaining parts such as row position, pressure lock, and pressure bar should also be hardware.
- 4. It is recommended to use straight lock or oblique lock.
The following items should be checked clearly when using the following items when quoting
- A. The thimble board needs to hold the toll.
- B. There should be wear-resistant blocks in the row position and pressure lock.
- C. Electroplating water transport hole.
- D. Electroplating cavity.
Medium production mold
- 1. Need detailed mold structure drawing.
- 2. The minimum hardness of mold base material is 16HRC.
- 3. The inner mold steel is P20 (28 ～ 32HRC) or high hardness (36 ～ 38HRC).
- 4. The remaining requirements depend on the needs.
Small-scale production of molds
- 1. Need mold structure drawing.
- 2. Mold material P20 (28 ～ 32HRC) can be mild steel or aluminum.
- 3. The inner module can be made of aluminum, mild steel or other approved metals.
- 4. The remaining requirements depend on the needs.
