What is the difference between several common plastic board processing techniques?
The application of plastics is becoming more and more extensive. There are many kinds of processing techniques. Among them, the more common ones are the blister process, the injection molding process and the blow molding process. So what is the difference between these common plastic board processing processes? ?
The blister process is mainly to heat and soften the plastic hard sheet, adopt a vacuum adsorption on the mold surface, and finally cool and form a processing method. It is widely used in plastic packaging, advertising, decoration and other industries. .
The injection molding process is a process in which plastic materials are melted, then injected into the mold cavity, and finally cooled and molded. The finished product shape through injection molding is the final product, and no other processing is required before use. Suitable for thermoplastics such as ABS sheet materials.
blow molding process, also known as hollow blow molding, is a relatively fast-developing plastic processing method. It mainly extrudes or injection molds thermoplastic materials, and then cools them. A processing technology to obtain hollow products.
There are both different aspects and similarities between the three different plastic plate processing methods. The blister processing technology requires the surface to be smooth and transparent, and the thickness to be balanced. The injection molding process requires complete consistency of product color and size, while the surface must be kept clean and tidy. The blow molding process requires a smooth surface, a balanced thickness, and a consistent weight and color.
