What is the Difference Between Blow Molding and Injection Molding?
The main difference between injection molding and blow molding is the types of products that can be produced. Generally, blow molding is the manufacture of hollow containers, such as bottles, pots, barrels and so on. There is no injection port on the surface, Injection molding is used to produce solid parts. The plastic granular material is first melted, and then injected into a closed mold under high pressure for shaping. There will be traces of the injection port on the surface.
What are the disadvantages of blow moulding?
Blow molding has many limitations due to the molding principle, so there are a few points that should be paid attention to when designing blow molding products:
● Only limited to hollow structural parts.
● The wall thickness is thin and the strength is low.
● By adding other materials in the multilayer part, the effect of blocking sound and heat sources is increased. (So not recyclable)
● A second trimming is required to remove burrs and excess material.
● Only for thermoplastics
Where is blow moulding used?
Blow molding is widely used in the production of hollow structure products, such as: water bottles, oil drums, chemical turnover barrels, floats, medical reagent bottles, etc. Injection blow molding is suitable for small container production, and stretch blow molding is suitable for medium and large-volume container products. However, the surface effect of injection blow molded products is better than stretch blow molding, and can be highly transparent and flat. Drinking water bottles are the most typical injection blow molding.
Is blow moulding expensive?
Blow molding will be more cost-effective than injection and rotational molding.
Generally speaking, the production cost of a product needs to refer to several factors, such as part structure design, product quantity, product material selection, and product application functionality. After a comprehensive analysis, we choose the most reasonable cost manufacturing process. Blow molding materials are relatively small, but for hollow structure parts, the structure is not complicated. When mass production is required, blow molding must be cheaper and more efficient than other plastic molding processes.
