High-precision machinery engineered for low to high viscosity applications, ranging from beverages to heavy lubricants.
The automotive and industrial lubricant sector faces strict standards regarding volumetric precision, spill containment, and chemical compatibility. Motor oils exhibit non-Newtonian flow behavior under pressure, and their viscosities vary greatly across temperature changes (ranging from thin 0W-16 winter oils to thick 80W-90 gear lubricants). Processing these liquids requires customized machinery that prevents foaming, manages drip, and maintains exact volumes.
As an experienced OEM exporter, our solutions address these issues by combining heavy-duty physical engineering with intelligent automation. We customize every component—from the fluid path to the diving nozzles—to match the chemical makeup of synthetic, semi-synthetic, and mineral motor oils. Our production lines optimize cycle times and prevent product loss, ensuring operations meet environmental and efficiency requirements.
Packaging technology is shifting from manual pneumatic configurations to intelligent, closed-loop feedback systems. This change is driven by the need to minimize product giveaway and enable quick changeovers between different bottle sizes. Our engineering roadmap focuses on three main technological pillars:
Moving away from mechanical stroke adjustments, our rotary servo drives control the piston movement to within fractions of a millimeter. This ensures accurate volumetric dispensing regardless of product viscosity fluctuations.
For operations requiring weight-based accuracy, we integrate Coriolis mass flowmeters. These systems calculate mass directly, eliminating error factors caused by changes in temperature and entrained air bubbles.
Modern production environments require live diagnostic reporting. Our PLC systems integrate with industrial networks, tracking component wear and supporting Clean-In-Place (CIP) programs to simplify product changes.
Our manufacturing base in China utilizes localized component networks, precision CNC machining, and scale-driven material sourcing. This combination allows us to build robust machinery that meets global performance standards while maintaining cost efficiency.
At Hebei Yongli, we manage the entire production cycle in-house. From raw laser cutting of SUS304/SUS316 stainless steel to the assembly of explosion-proof electrical panels, our processes ensure structural integrity and quality. This vertical integration allows us to keep lead times short and configure equipment to match your project specifications.
Founded in 2009, Hebei Yongli Machine Co., Ltd operates a 15,000㎡ manufacturing facility. We specialize in the research, development, and production of liquid and beverage packaging systems. Our product portfolio includes water treatment systems, daily chemical and beverage filling machines, labeling systems, shrink-wrap packaging, and complete automated production lines.
Over the past decade, we have focused on engineering durable machinery and delivering responsive technical service, helping packaging plants worldwide run efficient production lines.
International buyers need equipment that integrates into existing layouts and complies with local safety standards. Our engineering team designs custom configurations to match these facility parameters, ensuring smooth installation and operation.
We configure product feed lines with heat-jacketed hoppers and pressurized feeding circuits. This maintains consistent fluid thickness, preventing dripping or under-filling when handling heavy lubricants.
Motor oil packaging lines are built to comply with ATEX, IECEx, or Class I Division 2 requirements. This includes using explosion-proof motors, intrinsically safe wiring, and pressurized control enclosures.
Our quick-change tooling allows one machine to run 1L bottles, 4L canisters, and 20L pails. Tool-free adjustments minimize downtime during product changeovers.
From initial concept to line commissioning, we guide your project through a structured engineering workflow.
We design custom container layouts, product label paths, and machine footprints to fit your floor plan and production goals.
Following approval of designs, we manufacture the system using high-grade stainless steel and brand-name components, verifying operation against target bottle dimensions.
Our engineers provide on-site installation, system debugging, and staff training to ensure your team is ready to operate the machinery safely.

Answers to common design and integration questions from global buyers.
Our servo-driven volumetric piston systems maintain a filling accuracy of ±0.2% to ±0.3% of the target volume. This precision minimizes product loss and ensures compliance with global packaging regulations.
Our lines are built with modular star wheels and guide rails. Switchovers between plastic canisters and glass jars are managed via quick-change parameters on the HMI touch panel and tool-free neck guide adjustments.
Yes. For flammable or volatile chemicals, we construct the machine with explosion-proof motors (ATEX-certified), pneumatic control valves, and isolated electronics to meet facility safety codes.
We provide on-site commissioning by field technicians, real-time remote programming assistance, and keep a stock of standard wear parts (seals, nozzles, valves) ready for immediate shipment to prevent downtime.
