As a novel synthetic material, toy PVC granules are widely used in the manufacture of various toys. Because PVC is a kind of non-crystalline material, it is not easy to burn, resist oxidation and high strength, so it is very suitable as a production material for children's toys. From radios to guns and rockets, from flowers and insects to cartoon characters, colorful and varied, it has formed a dynamic world of modern plastic toys. Below we will specifically talk about the production process of toy PVC granules.

Toy PVC granules usually have two forms of presence: powdered and granulated. Compared to powder, granular processing has the following advantages:
1. The relative density of PVC granules is larger than that of powdered materials, and the strength of plastic products is better.
2, convenient feeding, do not need to install a forced feeder in the hopper.
3. The mixing of PVC resin with various solid powder materials or liquid additives is relatively uniform, and the physical properties of plastic products are better.
4, granular toy PVC granules containing less airborne volatiles, so that plastic products are not easy to produce bubbles.
5. Extrusion granulation is a basic and simple granulation method. The hard PVC granules have no pollution to the extruder and production environment.

The advantages of PVC granules are very high, which is more conducive to our production and processing. The production process of toy PVC granules is as follows:
1. Preparation before the ingredients. The preparation work before the general ingredients includes a plurality of processes such as resin sieving, plasticizer filtration, powdery additive refining, preparation of color masterbatch powder, and heating, melting and drying of the block additive.
2. After the preparation is completed, the formula needs to be weighed. According to the volume of the equipment and the feed coefficient, the amount of feed is estimated and mixed to obtain the raw material for mastication.
3. Kneading. The toy PVC granules can be heated and kneaded or cooled and kneaded by a high-speed kneading machine.
4. Extrusion granulation. Both single-screw and twin-screw machines can be used for extrusion granulation, which requires control of extrusion temperature, cutter speed, and pellet cooling. The size and size of the particles are made uniform, the granules are not sticky, and the plasticization property is good.
The above is the specific process of the production process of toy PVC granules. Toy PVC granules have a wide variety, diverse performance and simple processing, providing an ideal plastic material for the manufacture of modern toys.
