China MS vinyl toys Company, vinyl toy manufacturer
we custom made vinyl toys, vinyl figures, pop/designer vinyl toys, vinyl game/movie figures, vinyl characters, carton figures etc.The quality and safety hazards of toys made of recycled plastics may be manifested in three aspects:First, the strength, stiffness and impact resistance of plastic reduce, easy to be broken or broken, so that small parts or debris fall off, there is a risk of being swallowed by children, at the same time, its sharp tip is easy to harm children;Secondly, excessive plasticizer may be added, resulting in excessive plasticizer;Third, in the process of recycling and dissolution of waste plastics, the harmful substances in the solvent, especially the volatile organic compounds remaining on the finished products, may cause harm to consumers.Plastic toy manufacturers remind when buying toys to see plastic toys production address and product description. Avoid buying three no productsTemperature, the word we are familiar with, the proper temperature is one of the best, for example, shower, water was too cold is not good, it’s too hot is not good, is the best way to moderate, it is the most comfortable, for the mold temperature to its influence is very big, proper temperature can reduce the deformation of products, but also can improve the quality of products and so on. What are the effects of temperature on mold quality?First, can reduce the deformation of dongguan plastic productsThe mould temperature is stable and the cooling speed is balanced to reduce the deformation of the product. For products with inconsistent wall thickness and complex shape, deformation often occurs due to uneven shrinkage. Therefore, an appropriate cooling system must be adopted to keep the temperature of the mold and various parts of the core basically uniform, so that the plastic melt in the cavity can solidify at the same time.Second, can improve the surface quality of productsImproving the mold temperature can improve the surface quality of dongguan plastic products, too low mold temperature will make the outline of products is not clear and produce obvious fusion lines, resulting in increased surface roughness of products.Three, reduce the stress of the mold crackingFor crystalline plastics, the crystallinity is high. The greater the chance of stress cracking is, the lower the control temperature will be.Fourth, improve the stability of the dimensional accuracy of dongguan plastic productsBy using the temperature control system to keep the mold temperature constant, the molding shrinkage of dongguan plastic products can be reduced and the dimensional accuracy of dongguan plastic products can be improved. If possible, lower mold temperature can help to reduce the molding shrinkage of dongguan plastic products. For example, for crystalline plastic, because the mold temperature is low, dongguan plastic products crystallinity is low, low crystallinity can reduce the shrinkage rate. However, low crystallization is not conducive to the stability of the size of the products, starting from the stability of the size, and the need to properly increase the mold temperature, so that the crystallization of dongguan plastic products uniform.
