What is the difference between cast film machine and extrusion laminating machine?
The extrusion laminating machine is mainly composed of four types of machines, which are the main machine, the mirror roller system, the unwinding system, and the winding system. Sumino Machinery's laminating machine, the unit uses polyethylene, polypropylene and other raw materials, adopts the flat film extrusion coating process of the casting method, and is extruded to form a variety of substrates such as plastic woven fabric, paper, and non-woven fabric. It can be coated or compounded to improve the strength and compactness of the material. It is widely used in the production of plastic tents, shade cloth, geotextile, and heavy packaging materials.
Casting film machines are mostly single-layer structures and are specially used to make casting films. They use high-precision electronic ceramic casting machines, using alumina as the main raw material for ceramic casting, and first combine the crushed powder with The plasticizer, binder, dispersant, and solvent are mixed to make a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and coated on the special base tape with a certain thickness by a scraper. After drying and curing, it will be peeled off from the top. The thin film becomes the green tape, and then according to the size and shape of the finished product, the green tape needs to be processed by punching, laminating, etc., to make a finished product to be sintered.
The casting film machine is used for casting film. The casting machine feeds the mixed slurry into the material box through the feeding and defoaming device. The laser displacement sensor controls the height of the liquid level, and then it is made to have a certain strength and flexibility. After drying through a drying tunnel and multiple high-speed air nozzles, fully automatic film strip correction is carried out. The base tape and the green billet can be wound for use. After drying, the green billet can be peeled off and trimmed, and then cut to the user The specified width.
Extrusion Laminating machine is a kind of extrusion molding machine. It has the advantages of high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion fastness, smooth coiling, environmental protection, saving labor and raw material costs, etc.
