The difference between silicone parts and injection molded parts
Silicone parts and injection molded parts are two common plastic products, which are significantly different in terms of material, production process and characteristics.
First of all, silicone parts are mainly made of silicone material, while injection molded parts are made by injecting molten plastic material into the mold through the injection molding process. Silicone material has a high degree of softness and elasticity, while injection molded parts are usually made of harder plastics with a high degree of hardness.
Secondly, in terms of production process, silicone parts are usually made by mold cooling method, which has good flexibility and plasticity and is suitable for making complex shapes and structures. While the injection molded parts are made by melt injection process, the injection molding machine injects the melted plastic raw material into the mold, which is cooled and solidified and then demolded. Injection molded parts are faster and suitable for mass production.
In addition, silicone parts and injection molded parts have differences in physical properties. Silicone parts have better high-temperature resistance, not easy to deform or melt in a high-temperature environment, but also has a better cold resistance, in a low-temperature environment can still maintain the softness. The physical properties of injection molded parts depend on the selected plastic materials, and different plastics have different melting points, melting properties and high temperature resistance.
Besides, silicone parts and injection molded parts in the use of some differences. Silicone parts are often used in electronic products, medical equipment, baby products, etc., because of its excellent insulation and corrosion resistance, but also to meet the demand for flexibility. Injection molded parts are widely used in automobiles, home appliances, toys and other daily necessities. Injection molded parts usually have high hardness and strength, and can withstand a certain amount of pressure and weight.
Overall, silicone parts and injection molded parts, as common plastic products, have significant differences in material, production process, characteristics and uses. Understanding their differences helps us to better choose and apply the related products.
