Two-color injection molding machine, in short, is a plastic machine that can produce two colors of plastic products. The application of two-color injection molding machine will introduce these two different colors of raw materials into the two-color mold, and then produce a two-color plastic product with a certain look and even a grain. Today, a wide variety of two-color plastic products used in daily life are derived from two-color injection molding machines, such as a soft toothbrush, a small toy, and a computer keyboard

First, the principle of two-color injection molding machine

The two-color injection molding machine has two cylinders that are the same as the general cylinders in use and structure, but the two cylinders have safety channels and both contain opening and closing valves, and the safety channels are connected with the nozzle. After the raw materials in the two cylinders are melted, the proportion of materials required for each cylinder is controlled according to the opening and closing valve and the order of exclusion. The 200g injection molding machine is then shot into the mold core according to the nozzle, so as to make different kinds of two-color plastic products.

Two, two-color injection molding machine manufacturing regulations

In the matching raw materials of two-color injection molding processing, the injection molding two-color machine must meet the two main compatibility standards of bond phase dissolution and production process phase dissolution. Technically, the melting point of hard and soft rubber must have a temperature difference, this difference is generally around 30°, to 60° is appropriate, and the melting point temperature of the first shot raw material should be high. At the same time, in order to better ensure the adhesion of hard and soft adhesive, it can be completed by making pipe trenches or expanding the total contact area.

In the binocular design scheme of full transparent and non-full transparent, the first shot of the binocular design scheme of small lens is not fully transparent, and the second shot is the lens; In the double-shot design scheme used in the decoration design of precision injection molding machine, the first shot is not fully transparent, and the second shot is fully transparent raw materials.

Third, the use of two-color injection molding machine equipment

In everyone's daily life, you can often see the existence of two-color plastic products, two-color injection molding machine products are now used in several places such as appliances, mobile phones, vehicles, stationery, household appliances, decorations, and so on, and will soon cover more common industries in the future.
