Industrial Butter Bottle Moulds are core products in our industrial lubrication packaging lineup, specifically engineered for the Injection Molding of packaging bottles for industrial butter, lubricating grease, and other high-viscosity lubricants. These products have unique packaging requirements—they must be pressure-resistant to withstand stacking during storage and transportation, provide an airtight seal to prevent contamination and product degradation, and be durable enough to withstand the harsh conditions of industrial environments.

The mold cavity features a thickened wall design, which is optimized through structural analysis to ensure the finished bottle can withstand the required pressure loads. This design meets the strict safety standards for industrial packaging, ensuring the bottles remain intact even under heavy stacking or accidental impacts. The cavity surface is treated to achieve a high hardness level, enhancing wear resistance and corrosion resistance. This allows the mold to process a wide range of wear-resistant plastic materials, including HDPE and PP, which are commonly used for industrial lubrication packaging due to their excellent chemical resistance and durability.

The gating system employs an eccentric gate design, which is strategically positioned to direct the plastic melt away from the bottle’s critical structural areas. This prevents uneven wall thickness caused by direct melt impact, ensuring the bottle has consistent strength throughout. The cooling system features a layered waterway design, with separate cooling circuits for the bottle body and the neck. This targeted cooling approach ensures that both sections of the bottle cool at the same rate, preventing shrinkage inconsistencies and ensuring the bottle maintains its dimensional accuracy. The neck area, which is critical for sealing performance, receives special cooling attention to ensure precise thread formation and a smooth sealing surface. By addressing the unique requirements of industrial lubrication packaging, the Industrial Butter Bottle mould delivers durable, reliable, and high-performance packaging solutions for industrial butter and lubricant products.
