Cracking is a common defect in the manufacture of plastic products by plastic product manufacturers. The main cause is cracking due to stress and deformation. There are mainly residual stress, external stress and stress deformation caused by the external environment. Cracks caused by residual stress Residual stress is mainly caused by the following three conditions, namely overfilling, ejection from the mold and metal inserts. As the cracks generated in the case of overfilling, the solutions can be started in the […]

For plastic products, the degree of groovedness of the color of oil injection processing is generally selected above 10, do not choose low gloss matte, because its surface hardness will be relatively low, below 1H, and at the same time, the oil injection processing is not wear-resistant. Generally, the hardness of the paint after drying is above 2H, but when the hardness is too high, the paint will be brittle, so the general surface hardness should not exceed 4H. In […]

How to define our current plastic toys? Perhaps the requirements on safety performance of products such as toys for younger children must be quite high. So, is there a deadline for using plastic toys? The answer is yes. This is even more the case with current toy use features. Many parents do not have a good definition of plastic toys. They do not know what kind of use period of such plastic toys. The important thing is that in the […]

Plastic toys are colorful and have great ornamental value. The processing materials of plastic toy manufacturers are environmentally friendly and harmless plastic materials. The reason for rich colors is the coloring process. What coloring methods do plastic toy manufacturers have? The compound coloring technology can produce accurate, highly reproducible, deep and shallow injection molding products, suitable for small batch production. The masterbatch coloring method is divided into granules and liquid processing, which are made by mixing plastic and masterbatch together […]

If there is a strong odor during the processing of plastic products, this may indicate that the raw materials are defective, there are impurities in them, or some products are added. So how should we solve it? 1.Use more pure resin In many plastics, especially in plastics such as polyvinyl chloride, styrene, polyethyl acetate, and acrylate, the trace amount of residual monomers can produce an unpleasant smell. Use resins with very difficult monomer residues Eliminate those smells. It would also […]

In recent years, toy customization has become more and more popular. It can be said that it is a new marketing method for toy doll customization. In fact, it is also because most companies pay more attention to representative corporate mascots. With the emergence of more and more toy manufacturers in the market, the price of custom-made toys has been reduced. At this time, the toy factory needs innovation, because consumers ’shopping psychology changes from time to time, and they […]

During the melting and plasticizing process of plastic toys, plastic toys are prone to defects. The solution is to reduce the quenching stress after heat treatment to an ultra-low limit, because the quenching stress and the reticulated carbonized structure are under the action of the grinding force. The occurrence of phase transitions can easily cause cracks in the workpiece. Toy manufacturers stated that they need to use cooling lubricants reasonably, and play the three major functions of cooling, washing, and […]

Raw materials for plastic toys: Infiltrated into various auxiliary materials or additives by polymer synthetic resin (polymer) as the main component, which has plasticity and fluidity under specific temperature and pressure, can be molded into a certain shape, and under certain conditions. Keep the material in shape unchanged. Most of the raw materials for plastic toys are extracted from some oils. The most familiar PC materials are extracted from petroleum. PC materials have a gasoline smell when burned; ABS is […]

Due to climate change and pollution, plastics manufacturers estimate the environmental cost of using plastics to be estimated at $75 billion. However, cost savings can be achieved by closed-loop recycling and the use of biodegradable polymers. If you expand these behaviors, you can create a net worth of $3.5 billion a year. Citing the example of Dell closed-loop recycling, using recycled plastics from its own products to create new computers, according to plastics manufacturers, if every plastics manufacturer can recycle […]

In recent years, toy customization has become more and more popular. It can be said that it is a new marketing method customized by toy dolls. In fact, most enterprises pay more and more attention to representative corporate mascots, so the mascots of plush toys are more and more The market, with the emergence of more and more toy manufacturers, has created a situation in which the price of toy customization has been depressed. At this time, the toy factory […]
