Reliable Compressed Air for
Consistent Plastic Manufacturing
In plastic and rubber manufacturing, compressed air is critical to production. Unstable pressure, high energy consumption, moisture, and oil contamination can lead to inconsistent molding, higher operating costs, and production downtime.
⚙
Unstable Air Pressure
Keep Your Production Stable
Pressure fluctuations can affect injection molding, blow molding, demolding, and pneumatic equipment. Our compressor solutions provide stable pressure to support consistent production.
⚡
High Energy Consumption
Reduce Compressor Energy Costs
Compressors often run for long hours in plastic factories. Variable speed and two-stage compression technologies help match air supply to demand and reduce unnecessary energy consumption.
💧
Moisture & Oil Contamination
Protect Your Products & Equipment
Moisture, oil, and particles in compressed air can affect product quality and equipment. Our air treatment solutions combine refrigerated dryers and precision filters to deliver cleaner, drier air.
🔄
Continuous Production
Reliable Air, 24/7
Injection molding and blow molding require a dependable supply of compressed air. Sollant provides complete compressor and air treatment solutions designed for continuous industrial operation.
Common Challenges
❌ Excessive oil content leading to scrap: Oil leaks from oil-lubricated air compressors, and trace amounts of lubricating oil come into contact with the high-temperature melt via the compressed air, causing “silver streaks” or “black spots” on the surface of plastic parts, resulting in the entire batch being scrapped.
❌ Pressure fluctuations affecting dimensional accuracy: When supply pressure falls below 0.6 MPa, the clamping force of the injection-molded part is insufficient, resulting in flash; when it exceeds 0.8 MPa, it wastes electrical energy and shortens valve lifespan.
❌ Pipeline freezing causes shutdowns: Improper dew point control in winter causes saturated moisture in compressed air to condense into ice crystals at low temperatures, blocking precision pneumatic components (such as proportional valves and fine-orifice nozzles).
❌ High summer temperatures reduce air output: For every 5°C increase in ambient temperature, the actual air discharge volume of screw compressors decreases by approximately 4–6%, failing to meet full-load production line demands and forcing production cuts.

Project Case Studies
Compressed Air System Upgrade for a Rubber and Plastic Products Factory
Customer Pain Points: A medium-sized rubber and plastic factory operating 28 injection molding machines faced significant pressure fluctuations (6.5–9.2 bar) with its original fixed-speed air compressors. This resulted in a 3.8% defect rate during demolding and annual electricity costs of approximately 480,000 RMB, alongside high energy consumption and frequent maintenance requirements.
Solution: Installed one SLT-75V permanent magnet variable-frequency screw air compressor (75 kW; 8/10 bar; air delivery: 5.04–12.35 m³/min) as the primary unit. The system was complemented by a refrigerated dryer, precision filtration, and a 3 m³ air receiver tank, all optimized specifically for molding and demolding air requirements.
Implementation Results:
- Point-of-use pressure stabilized at 8.2–8.8 bar (fluctuation ≤±0.2 bar)
- Demolding defect rate dropped from 3.8% to 0.9%
- Average monthly electricity consumption reduced by approximately 35%, saving about 168,000 RMB annually
- Noise levels lowered to 68–70 dB; maintenance costs reduced by approximately 40%
