In today’s fast-paced consumer goods manufacturing sector, the production of plastic chopsticks relies on high-precision, high-efficiency mold systems. Among them, the mold base serves as the “skeleton” of the mold, carrying core components such as cavities and cores, directly determining the dimensional accuracy, surface quality, and production stability of the final product. A professional mold base manufacturer must not only provide high-strength structural support but also ensure long-term stable performance in high-temperature, high-pressure injection molding environments.
Why is the Mold Base So Important?
The mold base for plastic chopsticks molds is typically made from high-quality mold steels (such as P20, 718, S136, etc.) and possesses the following key characteristics:
- High Precision: Ensures tight fit between mold components, guaranteeing consistent length and thickness for each pair of chopsticks, with tolerances controlled within ±0.1 mm, or even achieving ultra-high precision of ±0.01 mm.
- High Strength: Withstands long-term, high-pressure cyclic operations of injection molding machines, preventing deformation or damage and extending mold service life.
- Excellent Thermal Stability: Maintains dimensional stability during high-temperature melt injection, ensuring consistency in mass production.
