Brief description of the difference and connection between rotational molding and blow molding


Plastic products are widely used in real life and will be used in all walks of life. But do you know how plastic products are made? What is the difference and connection between plastic products process rotomolding, blister, blow molding and so on?

Plastic products are widely used in real life and will be used in all walks of life. But do you know how plastic products are made? Plastic products are generally made of plastic through injection molding, rotational molding, blow molding and blister molding. As a professional rotational molding processing design and manufacturing manufacturers, often will just enter the industry newcomers asked:The difference between rotational molding and blow moldingWhat is the connection with? Is there any big difference? Now let's have a brief discussion.

Rotational molding process, also known as rotational molding process, rotating forming process, rotary molding process, etc., is a thermoplastic hollow molding method. The more common rotational molding products include various liquid chemical storage tanks, gasoline containers, various rotational molding pipe fittings (air conditioning elbows, backrests, armrests) for automobiles, as well as toys, models, handicrafts, etc. The blow molding process is also called a hollow blow molded article. The process method is thermoplastic resin by extrusion or injection molding of tubular plastic parison, hot (or heated to softened state), placed in the open mold, closed immediately after the mold in the parison into compressed air, the plastic parison blowing and close to the inner wall of the mold, after cooling demoulding, that is, to obtain a variety of hollow products. General common bottles, cans, baby supplies, sporting goods and other products are hollow blow molding products.

The rotational molding and blow molding products have the same point, that is, the rotational molding and blow molding products are hollow and the surface is not smooth enough. The surface of the rotational molding product is attached to the mold, and the material of the mold affects the touch of the surface of the product. Blow molding products will have blowing mouth, injection molding products will have injection molding mouth, rotational molding can be seamless molding.
