The circular plastic cutting board injection mold designed by Yige Mold is specifically customized for the balanced force distribution and convenient usage characteristics of circular products. It can be customized with a diameter ranging from 10 to 80 cm.
The mold is equipped with a ring-shaped hot runner system, which ensures uniform filling of the cavity with molten material, effectively addressing industry pain points such as center shrinkage and uneven thickness at the edges of circular cutting boards. The dimensional tolerance is strictly controlled within ±0.15 mm. The cavity is made of high-quality 718h mold steel and is processed as a whole by high-precision CNC engraving to create a concentric circular texture for anti-slip properties. Simultaneously, a forming area for ginger and garlic grinding protrusions is reserved. No additional processing is required, enhancing the practicality of the product.
The ring-shaped cooling water channel optimized for circular structures evenly distributes water to the cavity, increasing the cooling efficiency of thick-walled models by 30%. The molding cycle is compressed to 28-38 seconds, balancing efficiency and quality.
