1. Plastic & Rubber Machinery Industry (Largest Market Demand, Mainly PV2R Single/Double Vane Pumps)

1.1 Injection Molding Machines

• Small and medium-sized injection molding machines (50–800 tons): PV2R single and double vane pumps (dual flow for fast and low-speed operation), supporting mold clamping, injection, ejection, mold adjustment and core pulling hydraulic circuits
• Auxiliary pumps and lubrication cooling pumps for servo injection machines: SVPF variable vane pumps and small-displacement PV2R1 pumps
• Applicable models: horizontal injection molding machines, vertical injection molding machines, wire extrusion machines

1.2 Die-casting Machines, Blow Molding Machines & Extruders

• Cold-chamber and hot-chamber die-casting machines: PV2R2/PV2R3 large-displacement double vane pumps, providing stable oil supply for mold closing, pressure boosting and core pulling systems
• Blow molding machines, plastic extruders and rubber vulcanizing machines: PV2R fixed displacement pumps, supporting 24-hour continuous operation with low noise performance

2. Machine Tools & Precision Processing Equipment (Low Noise Required, PV2R1/2 & SVPF Preferred)

2.1 CNC Machine Tools & Machining Centers

• Vertical/horizontal machining centers, gantry milling machines and drilling & tapping machines: PV2R1 and PV2R2 pumps for fixture clamping, spindle tool release, tool magazine and auxiliary feed hydraulic systems

2.2 Grinding Machines & Precision Lathes

2.3 Special-purpose Machine Tools

3. Hydraulic Forming Equipment (Hydraulic Presses & Forging Equipment)

1. General hydraulic presses, four-column hydraulic presses, stretching machines and powder metallurgy presses
   1. Fast downward movement and working pressure maintaining: PV2R double vane pumps (large pump for fast feeding, small pump for pressure holding)
2. Leather embossing machines, sponge pressing machines and thermal laminating machines: SVPF variable pumps feature energy saving and low heat generation for stable low-pressure pressure maintaining work.

4. Automatic Production Lines & Tooling Fixtures (SVP/SVPF Variable Pumps as Main Products)

1. Tooling clamping cylinders, positioning cylinders, lifting platforms and transfer mechanisms for automatic assembly lines
2. 3C electronic jigs, mobile phone shell stamping equipment and battery packaging machines
3. AGV hydraulic lifting units and small hydraulic stations: Variable pumps automatically match flow rate according to variable load, featuring energy saving, low heat generation and low noise, which is suitable for indoor workshop working environment.

5. Testing Equipment & Laboratory Hydraulic Benches

1. Material testing machines, fatigue testing machines and tension & compression testing machines
   1. Static durability test: PV2R fixed displacement vane pumps
   2. Dynamic loading and stepless pressure regulation: SVPF variable vane pumps
2. Hydraulic teaching benches and seal pressure resistance test benches: 50T/150T low-cost low-pressure vane pumps with low procurement cost and easy maintenance.

6. Light Industry, Shoemaking, Packaging & Printing Machinery

1. Shoemaking machinery: hydraulic cutting machines, shoe mold forming machines and sole pressing machines (SVPF variable pumps to meet workshop low-noise requirements)
2. Packaging machinery: paper tube forming machines, carton pressing machines and hydraulic sealing mechanisms
3. Printing machinery: web tension control systems and hydraulic locking devices for printing rollers
4. Food machinery: food extruders and hydraulic filling equipment (low flow pulsation avoids impact on raw materials)
