What are the surface treatment processes of silicone products? Silicone products are a very popular product, silicone products have excellent performance and are applied in many fields. Many silicone products have a delicate appearance, which also benefits from the surface treatment process of silicone products.
1, pad printing process: Silicone products printing process is a relatively early surface treatment process, it is suitable for silicone, rubber and plastic hardware and other materials of the printing process, mainly using printing ink through the plastic head mechanical printing, in the early stage mainly using the screen plate for artificial wall chart, and has been basically eliminated, currently with the upgrade of machine equipment, Mechanical printing has developed to multi-color printing and printing multiple colors at the same time through the glue head.
The printing effect belongs to the plane, the surface has about 0.05MM printing steps, and the hand will feel a slight step bump effect.
2, molding: Silicone jewelry surface molding is easy, usually can also be directly made on the surface of the product, the product mold surface through the silicone products manufacturers processing concave and convex groove, directly put the silicone material into the mold pressing and curing molding products have concave and convex effect, usually many decorations are made into grooves, can be secondary filling oil processing, Add other colors of silicone ink to the grooves to make the surface of the product an additional pigment.
In addition to this way, it can also be molded twice to inject other colors into the surface, this way is not difficult, mainly because the other color K pieces must be put into the mold cavity in the filling processing, the resulting product will naturally be combined with color K to achieve multi-color effect, the difficulty lies in the process of dispensing glue and production efficiency.
3, silicone drop glue, drop glue is currently the most popular process in silicone decorative supplies, mainly through the mold injection into the face of the mold cavity, through the color allocation of color glue can be made at the same time more than a dozen colors, and the effect of the production of glue products will have a certain three-dimensional effect, touch the product can be in the middle of the mold line there will be a color separation slot, the size of about 0.5mm, The product effect made by this process has been recognized by many consumers, and it is also widely used in silicone decorative bracelets and watchbands.
4, transfer: transfer process is divided into many types, in the general film industry there are basically transfer process, such as hardware, ceramics, plastics and other industries, and silicone transfer there are mainly several ways.
Heat transfer printing is a more common processing of silicone bracelet, it is mainly printed pattern through high temperature PET polyester film that is printed into a heat transfer flower film, the heat transfer flower film installed on the heat transfer hot stamping machine for printing, simple operation, pattern molding, no need to color.
And when some products can not use heat transfer, it is necessary to use the water transfer process, water transfer with special chemical treatment of the film, after printing the required color lines, flat to the surface of the water, the use of water pressure, the color pattern evenly transferred to the surface of the silicone product, when the coating is automatically dissolved in water, after cleaning and drying, and then a layer of transparent protective coating, By this time the product has presented a completely different visual effect.
In addition to the above two transfer processes, silicone products are currently more common is the in-mold transfer effect, this way is the same as thermal transfer, the product pattern effect directly into the PET film production, through the mold design structure of the product for alignment molding, and the main technical control of this process is the open mold structure and the film plate alignment screen position. If the screen version is not strictly aligned, the resulting product will cause the overall offset.
