The forming process of acrylic bottle

The main material of the acrylic bottle is polymethyl methacrylate. The various acrylic bottles we have seen are heated in a high temperature environment, and various kinds of acrylic bottles can be obtained through the related molding process. different products.

1: Casting

The casting molding of the acrylic bottle is dissolved into a flowing liquid. Various shapes are produced in the mold by the method of bulk polymerization, and various styles can be obtained after cooling.

2: Injection molding

Injection molding requires the use of suspended polymers to produce various granular substances. The operation needs to be completed on a designated injection molding machine. After molding, internal stress is eliminated, and drying is performed in a hot air circulation drying environment of 80 degrees. The processing time From 3 hours to 8 hours, the time needs to be determined according to the specific thickness.

3: Extrusion molding

Extrusion molding is generally used for sheet processing of acrylic materials, and it is relatively rarely used for the molding of acrylic bottles. Single-stage and double-stage vented extruders are used to process various polymerized molecules in the equipment. Extrusion, to produce a variety of products of your different styles, with high production efficiency and low processing difficulty.

4: Thermoforming

Thermoforming is to soften the acrylic material after heating, and pressurize it so that the veneer can be close to the surface of the mold to obtain the same shape as the surface. After cooling and shaping, acrylic products can be produced. For complex acrylic Bottles, generally cannot be processed by thermoforming.
