Polyurethane casting equipment mainly consists of a metering system, a mixing system, and a control system. High-end equipment typically employs high-pressure metering pumps and automatic control systems, enabling high-precision and highly repeatable production.
Low-pressure casting equipment has a simple structure and is suitable for experimental or small-batch production; high-pressure equipment is suitable for large-scale industrial production, offering advantages such as uniform mixing and high efficiency.
Mold design is equally crucial in the casting process. Mold materials are typically chosen from steel, aluminum, or epoxy resin, based on service life and cost.
The mold structure needs to consider a venting system to prevent gas stagnation; simultaneously, a well-designed gate and runner system are essential to ensure uniform material filling.
