Silicone injection molding can meet the production of complex injection parts. Booling combines the precise temperature control technology of the injection molding machine with the high-precision processing technology of the mold to achieve large-scale production. As a new chemical material, silicone has excellent thermal stability. Compressed air is used to inject the molten silicone into the heated mold cavity. The silicone parts formed by cooling and solidification have high elasticity and impact resistance.
Silicone injection molding is economical and can be used for the manufacture and processing of various silicone products. It has strong biocompatibility.

Application of Silicone Injection Molding
Compared with traditional plastics, silicone has unique injection molding properties and can produce products with elasticity and a certain degree of toughness. It is widely used in automotive parts, aerospace, new energy, electronic equipment, medical equipment, video packaging, and other fields.
Guidelines for Silicone Injection Molding
Silicone has strong fluidity and good molding ability. Injection-molded products can replicate every detail of the mold and achieve micron-level accuracy.
Silicone injection molding uses molds and injection molding machines for precision molding. Booling injection molding machines have high-precision temperature and pressure control systems and automated processing functions. The molds have excellent cooling, exhaust, and ejection mechanisms. The two work together to achieve strict quality control.
Silicone Injection Molding Process
Booling provides a one-stop service for silicone injection molding from mold design to quality inspection and provides high-quality and high-precision silicone parts.
- Mold Design: Booling designers analyze the structure and size of samples or two-dimensional drawings, use CAD software to draw 3D drawings of molds, and obtain 3D models with complete structures
- Mold Processing: Purchase steel, standard parts, and mold frames for molds for processing. With the help of CNC machine tools, electric sparks, and wire-cutting technology, the mold can be precisely processed
- Injection Molding: After the mold is assembled and inspected, it enters the injection molding process. The silicone material and the corresponding additives are mixed to obtain a composite material. The mixture is injected into the mold cavity under high pressure to ensure that it is evenly filled before entering the next step to avoid short shots
- Cooling: The silicone material is vulcanized and cooled in the mold to achieve the transformation from liquid silicone to solid elastomer. At this time, Booling engineers need to strictly control the curing time and temperature to ensure the stability of the product.
- Ejection: The molded silicone parts are ejected, the flash is removed, and the silicone parts are carefully inspected as a whole to ensure that there are no defects in the product, the accuracy meets the required requirements, and defective parts are removed
Equipment Structure of Silicone Injection Molding
Each structural design of silicone injection molding equipment can directly affect the quality of silicone parts, mainly including injection molding system, clamping device, etc., to achieve precise control of each parameter in the processing process.
The clamping device of silicone injection molding is responsible for keeping the mold closed during the processing process. The force applied by the clamping device can ensure that the mold remains tightly closed to prevent silicone material leakage or flash caused by loose closure.
In addition, the injection molding process also includes various auxiliary systems, such as a cooling system, exhaust system, and robot control system, which can realize automation in the processing process, improve processing efficiency, and avoid defects.
Silicone injection molding can achieve high precision and reliability of product processing, and produce parts with strict tolerances and stability through strict quality control. Booling’s injection molded silicone parts have been exported to many countries such as Russia, India, South Korea, Germany, Argentina, etc., and have been unanimously recognized and praised.
