Briefly describe the difference and connection between rotomolding and blow molding
Plastic products are more widely used in real life, and are used in all walks of life. But do you know how plastic products are manufactured? Plastic products process rotomolding, blister molding, blow molding and other differences and connections and what is it?
Plastic products are more widely used in real life, and are used in all walks of life. But do you know how plastic products are manufactured? Plastic products are generally made of plastic as raw materials through injection molding, rotomolding, blow molding and vacuum molding processes. As a professional rotomolding processing design and manufacturing manufacturers, often asked by newcomers who will just enter the industry: rotomolding and blow molding differences and links are? What is the big difference? Now we will give you a brief discussion to see.
Rotational molding process, also known as rotational molding process, rotational formation process, rotational molding process, etc., is a thermoplastic plastic hollow molding method. The more common rotomolding products are various liquid chemical storage tanks, gasoline containers, automobile rotomolding fittings (air-conditioning bends, backrests, armrests), and toys, models, handicrafts and so on. The blow molding process is also known as hollow blow molding products. The process is a thermoplastic resin by extrusion or injection molding of tubular plastic parison, while hot (or heated to a soft state), placed in a folio mold, closed immediately after the mold into the parison of compressed air, so that the plastic parison blowing and tightly adhering to the inner wall of the mold, the cooling demolding, that is, to obtain a variety of hollow products. General common bottles, jars, baby products, sporting goods and other products are hollow blow molded products.
Rotomolding and blow molding products have the same point, that is, rotomolding, blow molding products are hollow, the surface is not flat enough; rotomolding products are attached to the surface of the mold, the material of the mold affects the surface of the product feel. Blow molded products will have blowing mouth, injection molded products will have injection mouth, rotomolding can be seamless molding.
