Acrylic, also known as PMMA or Acrylic, is derived from English acrylic (acrylic plastic). The chemical name is polymethyl methacrylate, which is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance. Has a wide range of applications. Plexiglass products are generally classified into cast sheets, extruded sheets, and molding compounds. In the field of cosmetic bottle pack...
1. Cast molding Cast molding is used to form profiles of plexiglass sheets, rods, etc., that is, forming profiles by bulk polymerization. The cast product needs to be post-treated, and the post-treatment conditions are 2 h at 60 ° C and 2 h at 120 ° C. 2. injection molding Injection molding uses pellets obtained by suspension polymerization and is formed on a conventional plunger or screw injection molding machine. Injection molding products also need post-treatment to eliminate internal stress....
Thermoforming is a process of forming a plexiglass sheet or sheet into articles of various sizes and shapes. The blank cut into the required size is clamped on the mold frame, heated to soften it, and then pressed to make it close to the mold surface. The shape is the same as that of the profile, and the product is finished by trimming the edge after cooling and setting. The pressurization may be by vacuum drawing or by direct pressing of a punch having a profile. The thermoforming temperature c...

Acrylic bottles are not only resistant to plastic, light, easy to color, easy to process, low cost, but also have the characteristics of glass bottles, beautiful appearance and high quality. It allows cosmetic manufacturers to obtain the appearance of glass bottles with the cost of plastic bottles, and also has the advantages of resistance to falling and transportation.
