The plastic children's low-seat mold is a specialized molding system developed specifically for children's body characteristics and usage scenarios. Such molds must meet the basic load-bearing requirements (usually ≥ 50kg), while also taking into account the safety, lightweight (single-piece weight controlled within 0.8 - 1.2kg), and fun design for children's use.
The mold design adopts a rounded corner safety structure, with all edges rounded to a radius of R ≥ 2mm. The surface of the cavity is formed with anti-slip textures through etching or sandblasting processes, with the friction coefficient controlled within the range of 0.4 - 0.6. The pouring system employs the three-point balanced injection technology to avoid the appearance of weld marks in the load-bearing area; the cooling system adopts a multi-layer loop design, shortening the molding cycle by 18% while ensuring dimensional stability. The demolding mechanism is equipped with elastic pins and pneumatic auxiliary devices to prevent deformation of thin-walled parts (average wall thickness 2.5mm).
Yige Mold has introduced the modular design concept in this field. By replacing different shape modules, various designs such as animal shapes and block assembly can be achieved on the same mold base.
