A casting machine refers to a specialized equipment used for producing casting films. Using a high-precision electronic ceramic casting machine, alumina is used as the main raw material for ceramic casting. The crushed powder is first mixed with binders, plasticizers, dispersants, and solvents to form a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and pressed onto a dedicated base tape with a certain thickness by a scraper. After drying and curing, it is peeled off from the top to become a thin film of the raw material strip. Then, according to the size and shape of the finished product, the raw material strip is processed by punching, laminating, etc. to produce the raw material product to be sintered. It has the advantages of low cost, high quality, non-toxic, and simple production process.
Characteristics of Domestic Cast Film Production Line:
1. The domestic cast film production line can be divided into 2500mm, 3000mm, 3500mm, and 5000mm according to the film width, and can be divided into three layers, five layers, and seven layers according to the configuration of the extruder.
2. The domestic cast film production line mainly consists of five parts: extrusion part, cast part, corona discharge part, winding part, and electric control part. The mold and extrusion parts can be freely combined according to customer requirements, thus maximizing the satisfaction of a wide range of customers (different market demands).
In addition, domestically produced equipment also closely follows the international advanced level in design, such as:
A, The unique design of the back device allows for free adjustment of the extruder pressure.
B, The unique design of the screw flow channel can be applied to different materials, achieving multi-purpose use for one machine.
C, The flow channel design of the roller provides better cooling effect, more stable product quality, and higher output.
D, The production line speed of domestically produced cast film has reached a level of 160m/min to 250m/min.
Compared with imported equipment, domestic cast film production lines also have the characteristics of high speed, stable performance, environmental protection, and energy saving. The thickness of the product ranges from 0.017mm to 0.08mm (calculated according to international standards as 0.025mm).
