20L Oil bucket moulds
2026-07-31
When selecting molds for 20L plastic oil buckets, multiple core factors need comprehensive evaluation to match mass production demands.
- Mold steel selection is critical. We recommend corrosion-resistant and high-hardness mold steel to cope with continuous injection molding of PP/HDPE raw materials, effectively extending the service life and reducing frequent maintenance downtime.
- Optimized mold cavity design. Reasonable runner and cooling system layout ensures uniform product cooling. It helps oil barrels achieve stable wall thickness, avoiding deformation, leakage and surface sink marks after molding.
- Precision sealing structure design. The mold reserves precise forming positions for bucket mouth, handle and sealing rib, guaranteeing the tightness of finished oil barrels, which meets the packaging standard of edible oil and industrial lubricants.
- Stable ejection system. Balanced ejection structure prevents product sticking and barrel body distortion during demolding, improving the yield rate and lowering defective product costs.
- Customization flexibility. Support personalized modification such as bucket surface logo, anti-slip texture and handle shape. We can adjust mold solutions according to customers’ exclusive product drawings.
- After-sales technical support. Complete mold trial service is provided. Technicians can adjust molding parameters on site, and supply long-term spare parts to guarantee uninterrupted customer production.
