How injection molding works？

Injection molding is an extremely efficient part production process that quickly transforms plastic particles into products with complex designs. At the heart of the process is the melting of thermoplastic particles, which are then injected into a mold under high pressure. With mechanical control, injection molding can produce complex structures with precision, making it ideal for the production of everything from simple containers to complex components. In terms of materials, several injection molding supplies such as PP, PE, PVC, and PBT can be used, which play a crucial role in determining the durability and properties of the final product. According to the 2024 Global Plastics Processing Report, PVC injection molding alone accounts for 18% of the global plastics processing market.

In injection mold manufacturing, although metal molds are known for their high mechanical strength and long life, their excellent wear resistance also leads to a long processing cycle for mold processing, usually 4 to 8 weeks. According to the material, process, mold fineness and other factors, the production time may also exceed this range. If customers need to get parts quickly, LVMA factories can adopt the form of 3D printing to help customers quickly produce products or complete the transition of capacity climbing period. However, it is important to note that while 3D printing technology eliminates the time required for mold manufacturing, its per-part production efficiency is far lower than injection molding. Consequently, in large-scale production scenarios, the lead time to meet order demands with 3D printing would be significantly longer compared to injection molding.

With the continuous development of the injection molding industry, customers' demand for high-quality and affordable plastic parts continues to grow. LVMA always focuses on customer demand and continues to provide global customers with customized injection molding solutions with high precision and reliability through four core strategies of technological innovation, process optimization, quality control and service upgrading.
