1x4

Injection System

Cold Runner

Core Material:

LKM 738H

Type of gating:

edge gate with  sprue cutter inside the mold

Cavity Material:

LKM 738H

Ejection system:

ejector stripper plate

Slider material:

718 with heat treatment

Lead time for production

40 days

Mold base steel:

1045

Shot life:

300 000

Export  mold:

yes, we send the mold to our USA customer

Production cycle time:

40 s

 

 Product Characters:

1)     Critical important for the surface finishing, no any default for the outside and inside the plastic housing

2)     Push out by ejector stripper plate and can't easily find the lines

3)     Very strong and thick wall for the part design, No shrinkage marks or rib marks

4)     You can't find the gating location because we use the inside mold gate automatically cutting technology when the injection holding pressure is finished within 2 seconds

5)     Early supplier involve ( ESI) for production development due to lack of mechanical engineering capacity at customer side and Asia Billion help them for the custom plastic housing design main jobs

6) no welding line or flow marks for the holes

738H pre-hardened plastic mold steel Introduce


   738H is a common plastic injection mold steel , it is widelt used for many difference places , today Asia Billion will show you more details to help you understand this steel. 


 738H steel chemical composition: C: 0.30 Si: 0.30 Mn: 1.50 Cr: 2.00 Ni: 1.00 Mo: 0.20 P: 0.020 S: 0.003


738H feature application:

   738H, using vacuum degassing and refining, the steel is pure and the structure is uniform. The hardness distribution of large section thick plates is very uniform. 738 die steel has excellent polishing and toughness, excellent hardenability and uniform distribution of large section thick plates. In addition, 738 mold steel has excellent processing performance, easy cutting, grinding and electric erosion. 738 mold steel is mainly used in large-scale plastic molds, such as refrigerators, air-conditioning molds, etc., as well as molds with high gloss finishing requirements such as hard rubber (PS) and ultra-tempering (ABS).


738 mold steel physical properties: temperature 20 ° C, 250 ° C ,500 ° C


Density kg/m3: 7800, 7750 ,7700


Elastic modulus N/mm2:  212000, 197000, 175000


The coefficient of thermal expansion is from 20 ° C to 106 / ° C:  11.6 ,12.8 ,14.3


Heat transfer coefficient W/m: C34.0, 33.5, 33.0


738 mold steel nitriding treatment:

   Nitriding treatment can obtain a hard surface layer, increase the wear resistance and corrosion resistance of the material, and the hardness after nitriding in ammonia gas can reach 650HV.

   Nitriding temperature (°C) time (h) concentration (mm)

525 20 0.29

525 30 0.36

525 60 0.50


Benefits of using 738H die steel:


   738H mold steel adopts iron ore blast furnace steelmaking, refining outside the furnace, vacuum degassing, forging using three forging and three drawing, and other advanced steelmaking processes. The obtained 2738H material has high purity, good compactness, high hardness and uniformity, and smooth milling and milling. The hardness is up to HRC38°, the mold is difficult to collapse, the product will not be draped, and the die life is 13%; the material purity is high and the mold polishing is good. Available within 830mm.


738H mold steel applications:


  738H mold steel is suitable for molds requiring high gloss uniformity such as production of hard rubber (PS) and ABS. Suitable for large-sized, especially thicker than 400mm, plastic molds with uniform hardness, high toughness and good surface finish; such as home appliances, TV shells, copier shells, bumpers, shock absorbers, instrument panels and other large molds; And trash can mold; die-casting mold base.


 738H is a high wear-resistant pre-hardened plastic mold steel with a quality rating between P20 and 718. The domestic 2738H has six quality grades, and the price is even more strange. The price quoted by some merchants is so low that you doubt life. Everyone has a different mentality in doing business and different gestures. Low-cost suppliers are holding the mentality and gestures of doing business with you; high-priced suppliers are holding the mentality and gestures of doing business with you for a lifetime; different attitudes, you get different products and services.


   Asia Billion is a professional Custom Plastic Housing For Electronics and mold manufacturer. We clearly understand the requirements of our customers and the performance of steel. We use high quality mold steels such as LKM 738H for our mass production products, and provide global Proof of traceable steel material. This is not a guarantee that unscrupulous merchants who often do ultra-low prices can do it. If you have any need for custom molds and injection molding products, please feel free to contact us!
