baby bottle manufacturing process
This article will show you baby bottle manufacturing process.
The baby bottle production process is also called plastic molding processing (referred to as plastic processing). It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production sector in the plastics industry. The following editor of Bianbao.com introduces the plastic production process.
Plastic ingredients
In addition to polymers, various plastic additives (such as stabilizers, plasticizers, colorants, lubricants, strength agents, fillers, etc.) are generally added in addition to polymers to improve the molding process and product performance. Or reduce the cost of the product. Additives and polymers are mixed and uniformly dispersed into powder, also known as dry mix. Sometimes the powder needs to be plasticized into pellets. Such powders and pellets are collectively referred to as batch materials or molding compounds.
Plastic molding
The key link in plastics processing. Various forms of plastic (powder, pellets, solutions or dispersions) are made into products or blanks of the desired shape. There are more than thirty methods for molding. Its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. Common methods for processing thermoplastics include extrusion, injection molding, calendaring, blow molding, and thermoforming. Thermosets are generally processed by compression molding, transfer molding, and injection molding. Laminating, molding, and thermoforming are molding plastics on a flat surface. The above plastic processing methods can be used for rubber processing. In addition, there are castings using liquid monomers or polymers as raw materials. Among these methods, extrusion and injection molding are the most used and are the most basic molding methods.
Introduction to plastic production process steps
Plastic parts
The methods of joining plastic parts include welding and bonding. The welding method is hot air welding using electrodes, hot-melt welding using hot electrodes, and high frequency welding, friction welding, induction welding, ultrasonic welding, etc. The bonding method can be divided into flux, resin solution and hot-melt adhesive bonding according to the adhesive used.
Plastic assembly
The operation of assembling finished plastic parts into a complete product by means of bonding, welding and mechanical connection. For example: plastic profiles are assembled into plastic window frames and doors through sawing, welding, drilling and other steps.
Machining
Borrowing methods such as metal and wood can be used to manufacture plastic products with very precise or few dimensions, and can also be used as an auxiliary process for forming, such as sawing of extruded profiles. Due to the different properties of plastics from metals and wood, plastics have poor thermal conductivity, low thermal expansion coefficient and low elastic modulus. When the clamp or the tool is pressurized too much, it is easy to cause deformation. It is easy to melt when heated and stick to the tool . Therefore, when machining plastics, the tools used and the corresponding cutting speed must be adapted to the characteristics of plastics. Common machining methods include sawing, shearing, punching, turning, planing, drilling, grinding, polishing, and thread processing. In addition, plastics can be cut, drilled and welded with lasers.
Surface Modification
The purpose is to beautify the surface of plastic products, usually including: mechanical modification, that is, using files, grinding, polishing and other processes to remove burrs, burrs, and correct dimensions, etc .; painting, including coating the surface of the article with a coating The surface is bright, and the surface of the product is covered with a patterned film; color application, including color painting, printing and hot stamping; metal plating, including vacuum coating, electroplating, and chemical silver plating. The hot stamping is to transfer the colored aluminum foil layer (or other pattern film layer) on the hot stamping film to the product under heat and pressure. Many household appliances, building products, daily necessities, etc., use this method to obtain patterns such as metallic luster or wood grain.
