Four major differences between injection molding and blow molding processes for child safety seats:
Plastic parts are a large part of the child safety seat. The quality of the plastic parts determines whether it will break in the event of an accident. The processing of child seat plastic molds is mainly divided into two processes: injection molding and blow molding. What are the two industries? Let's take a look.
1. Material
There are two main types of safety seats currently on the market:
Injection molding: PP for short
Blow molding: HDPE5502 for short
2. Structure
Injection molding:
(1) The structure of injection molded parts is relatively complex
(2) Suitable for products with relatively complex structures
(3) Since injection molded parts only have a single wall thickness and are generally not strong enough, iron parts are generally added to the injection molded parts to increase the strength of the seat.
Blow molding:
(1) The structure of blow molded parts is relatively simple
(2) Suitable for products with relatively simple structure
(3) The blow molded parts are double-walled, relatively strong, and can withstand the strength of the seat during impact.
3. Craftsmanship
Injection molding: Injection molding uses an injection molding machine and a mold to press the plastic melt into the mold to form it.
Blow molding: Blow molding is an extruder that extrudes the plastic melt into a hollow shape and then places it on the mold, and uses compressed air to expand the hollow melt into shape.
4. Advantages and Disadvantages
Injection molding:
Advantages: (1) Beautiful surface
(2) The seat has many functions
Disadvantages: (1) The seat is bulky
(2) Complex structure
(3) The cost is relatively high
Blow molding:
Advantages: (1) Simple structure
(2) The seat is relatively light
(3) High cost performance
(4) The plastic is hollow and has better energy absorption effect.
Disadvantages: (1) The function is relatively simple
(2) The surface appearance is not very beautiful, and the product quality looks low.
