  plastic granules volumetric doser Details description
product name:plastic granules volumetric doser
release time:2020-05-08 08:28:39
simple description:Volumetric doser are designed for auto-propotional mixing of 1 new material and 1-4 kinds of masterbatch/additives for the injection, extrusion and blow-moulding production. Each of the dosers is applied with a stepper motor and microcomputer controller. They can accurately caculate the proportion of the masterbatch and additives. This volumetric doser can be connected with any kind of molding machines and fulfill synchronized operation, which assures the quality of the product.

plastic granules volumetric doser Equipment principle

The signal from the control box is transmitted to the motor, and the motor starts to rotate, driving the screw to rotate through the coupling. The color masterbatch in the hopper falls into the falling rod, is squeezed by the screw, and is transported into the base by the screw, so as to achieve the purpose of accurately measuring and transferring the color masterbatch.

Modular detachable structure design, can quickly change the screw and sleeve;
Using high-precision hybrid stepping motor, accurate measurement and wide output range;
Directly driven by the motor, no gearbox, long life and maintenance-free;
The microprocessor controller is easier for operation.
With 50 sets of formula access function, it can be quickly called to start the machine;
The screw is chrome-plated and durable;
The measuring part can be removed from the base as a whole without material leakage. The side of the base is equipped with a window device.

plastic granules volumetric doser Precautions

     1.The mixing chamber of the injection molding machine or the masterbatch machine generally has multiple temperature zones, and the temperature near the blanking port should be slightly higher. This is to make the masterbatch melt quickly after entering the mixing chamber, and quickly mix with the plastic resin , This will help the masterbatch pigment to be in a good dispersion state in the product.

       2. Appropriately apply back pressure to the injection molding machine, which can improve the mixing effect of the screw and facilitate the dispersion of the pigment. The side effect of applying back pressure is to slow down the injection speed.

       3. The temperature of the die head of the color master extruder is appropriately increased, which can increase the brightness of the product.

       The masterbatch maker mentioned that the basis for confirming the masterbatch application share is to obtain a satisfactory coloring effect. As long as the color of the product is uniform and there are no stripes or mottles, it can be recognized.

       1: 100 Unless the mixing of the equipment is very good, it will simply show the phenomenon of uneven pigment dispersion, and it is generally not recommended for customers to use this share.

       However, due to price pressure, some customers who use masterbatch machines particularly want to use this share of masterbatch. Masterbatch manufacturers consider it for customers and generally can meet the requirements.

       1:50 is used for coloring general plastic products, PE, PP masterbatch mostly use this share.

       1: 33--1: 25 is used for PO products with high color requirements, and ABS products with low color requirements or general.

       1:20 for gao-grade plastic products, including PO and ABS, can be widely used in injection molding, blow molding, spinning and other processes.

       1:20 or more It is generally used for coloring gao-level cosmetic containers, and is mostly used for small injection molding machines.
