In a game-changing update for the automated filling equipment industry, Dongguan Dihai Automation Intelligent Equipment Co., Ltd. has upgraded its flagship filling machine to support an unprecedented range of materials, including not only CBD and THC oils but also petroleum jelly. This innovation breaks traditional equipment limitations, catering to diverse production needs across healthcare, cosmetics, and wellness sectors.
Versatile Filling Capabilities for Multiple Materials
The upgraded machine features a high-precision temperature control system (adjustable range: 25°C–100°C) that efficiently heats petroleum jelly into a fluid state, enabling seamless filling into standard containers of 1ml, 2ml, 3ml, and 5ml. Unlike conventional machines restricted to low-viscosity liquids, this equipment adapts to varying material properties through optimized pump pressure and needle design-ensuring consistent dosing accuracy of ±0.03ml for both oil-based substances (CBD/THC oils) and thermally liquefied semi-solids (petroleum jelly).
"Our goal is to provide a one-stop filling solution for manufacturers," said a senior R&D engineer at Dihai Automation. "Whether it's cannabis-derived extracts for wellness products or petroleum jelly for skincare and medical applications, this machine delivers reliable performance without the need for costly tool replacements."
Intuitive Cleaning System Boosts Operational Efficiency
Addressing a key pain point in production line maintenance, the machine integrates an automated cyclic cleaning function. Operators simply fill the oil tank with alcohol, initiate the cleaning cycle, and the system flushes internal pipelines, needles, and reservoirs automatically. This process eliminates residue buildup from different materials (e.g., sticky petroleum jelly or concentrated cannabinoid oils) in just 5 minutes, cutting maintenance time by 70% compared to manual cleaning methods.
The self-cleaning feature not only enhances production hygiene-critical for compliance with FDA and EU regulatory standards-but also minimizes downtime between product line switches, enabling manufacturers to handle small-batch, multi-SKU orders more efficiently.
Market Implications for Cross-Industry Applications
With the global CBD market projected to reach $102.8 billion by 2028 and the petroleum jelly-based product sector growing steadily at 4.2% annually, this versatile filling machine is poised to capture demand from diverse industries. Small and medium-sized enterprises (SMEs) stand to benefit most, as it eliminates the need to invest in multiple specialized machines, reducing capital expenditure and streamlining production workflows.
Dihai Automation has already received pre-orders from clients in the U.S., Germany, and Southeast Asia, with initial shipments scheduled for Q4 2025. The company plans to expand its material compatibility further, with future upgrades targeting additional high-viscosity substances such as waxes and emulsions.
For manufacturers seeking to enhance production flexibility and operational efficiency, this innovative filling solution marks a significant step forward in automated manufacturing technology.
