The child safety seat is made of polypropylene, a tough plastic that flexes under pressure and doesn't crack easily the way some other plastics do. Plastic Car Safety Seat Injection Mould use P20 steel S136 for cavity and core with single cavity
Plastic Car Safety Seat Injection Mould
Also after June 1, 2021, China also urgent that children under 8 must seat on the safety seat when driving on the way.
How To Select The Plastic Mould Steel
The plastic Car Safety Seat Injection Mould steel choice depends on expected mold overall life, part surface roughness and plastic materials .
The higher the overall life of the mold should be , the higher demand for wear resistance and hardness of plastic mould steel should ask for .
Transparent products require cavity to be mirror polished, and S136H, PAK80, PAK90 , 420 and other high-quality steel are better choice.
In terms of the plastic material, heat-sensitive plastics (eg PVC, etc.) must select anti-corrosion steel, such as S136H,PAK90 .
Relative sliding mold parts should use different steel and hardness, hardness difference is 2 HRC.
Steel For Mould Parts
if Car Safety Seat Injection Mould core material and insert materials are same, the hardness of core should be below the insert hardness by about 4 degrees.
dowel pins material: SKD61 (52HRC).
steel for slide parts and core-pulling mechanism:
1.lateral slide parts and core or cavity inserts should be made of different steel if relative sliding is needed for them; But if it really need the same steel for mold inserts material and the sliding block,sliding block’ surface must be nitrided, and its hardness should be below around 2.
2. slider block material: P20 or 718.
3. locking blocks: S55C (required heat treatment to 40HRC) or DF2 hardened to 52HRC.
4.wear plate: DF2 hardened to 52HRC.
5.angular pins: SKD61 (52HRC).
6.wedge block: S55C.
7.guide block : DF2 (oil heat treatment of steel required to 52HRC).
lifter steel: lifter steel and mould inserts steel can not the same for the lifter rod could be scratched when sliding.
Hongmei company try our best to use good steel and good stand of mould spares, because we know that good steel not only have good surface of the parts but also get long life and low maintain, this could help our customers short the Car Safety Seat Injection Mould
fix time and have considerable annual output.
