Paint bucket mold

The paint bucket injection molds professionally manufactured by our company take pressure-resistant sealing molding and high durability as their core competitiveness. Made of imported pre-hardened mold steel, the molds undergo precision CNC machining and multiple heat treatments, with excellent fatigue resistance and corrosion resistance, suitable for injection molding of anti-corrosion raw materials dedicated to paint buckets such as PP and HDPE. To meet the sealing requirements of paint buckets, we optimize the design of mold parting surfaces and thread structures, and cooperate with precise cavity size control to ensure tight fit between the bucket mouth and lid without leakage risks. The bucket body has uniform wall thickness (tolerance ≤ 0.25mm) and compressive strength of over 150kg/cm². The molds support customization of conventional capacities from 1L to 20L and non-standard sizes. Equipped with an efficient circulating cooling system, the single injection cycle is shortened to 55-85 seconds, enabling integrated molding of the bucket body and handle. They are widely used in packaging production scenarios of coating, chemical, building materials and other industries.
