Thick wall blister discusses the difference between blister, injection molding and blow molding
The three processes of blister, injection molding and blow molding are all related to plastics, but the major differences between them are poorly understood. The small series of thick wall plastic manufacturers will introduce the main differences between these three processes.
Blister, the main principle is to flatten the plastic sheet after heating and softening, using vacuum adsorption on the mold surface, cooling molding. It is mainly suitable for products with simple structure, single-sided molding and small quantity. Mold cost-effective. It costs only 1/20 of the injection mold. The opening time of similar complex products only needs 1/4 of the injection mold.
Injection molding refers to the melting of plastic raw materials, through the injection molding machine high pressure into the mold, cooling molding. Suitable for large quantity, high precision products, mold costs are very high.
Hair dryers, also called hollow hair dryers, are a rapidly developing plastic processing method. It is mainly used for the production of hollow products, such as bottles and cans, etc., and the mold price is not much different from the molding mold.
