FAQ
Q1. How do I choose the right filtration system for my specific materials?
A: The choice of filtration system primarily depends on the contamination level of the material, production output requirements, and the quality standards for the final product:
High Contamination (e.g., post-consumer films, mixed waste) 👉 Recommended: Self-cleaning filters or backflush filters
Moderate Contamination 👉 Recommended: Dual-piston screen changers or plate-type filters
High Particle Quality Requirements (e.g., films, sheets) 👉 Preferred Choice: Backflush filters
👉 We recommend providing material samples or specifications so that we can customize the optimal solution for you.
Q2. Will the filtration system affect granulation output?
A: No; on the contrary, it will enhance overall production efficiency.
Automatic filtration systems enable continuous, non-stop operation
They reduce downtime associated with screen changes, thereby increasing actual output
They stabilize pressure, improving extrusion efficiency
👉 In practical applications, customers typically achieve higher, more stable output with fewer losses due to downtime.
Q3. What level of contamination can the filters handle?
A: Different filtration systems possess varying capabilities:
SCF Self-Cleaning Filters: Can handle impurity levels of up to approximately 5%
Backflush Filters: Suitable for highly contaminated post-consumer plastics (PCR)
Traditional Screen Changers: Better suited for materials with low to moderate contamination levels
👉 If your material contains complex impurities (such as paper, metal, wood chips, etc.), we recommend prioritizing the SCF filtration system.
Q4. What advantages do automatic filtration systems offer compared to traditional screen changers?
A: Automatic filtration systems (such as the SCF) offer distinct advantages:
✅ No need for downtime; enables continuous production
✅ Automatic cleaning reduces the need for manual intervention
✅ More stable melt pressure
✅ More consistent particle quality
✅ Lower maintenance costs
👉 Particularly well-suited for production lines with stringent requirements regarding stability and product quality.
Q5. Can ACERETECH provide customized filtration solutions?
A: Yes, ACERETECH offers comprehensive customization services:
Based on material type (PE, PP, PET, etc.)
Based on contamination levels and production output requirements
Based on the intended application of the final product (blown film, injection molding, sheet extrusion, etc.)
👉 We match each client with the most suitable combination of filtration systems to ensure the best cost-performance ratio and long-term operational stability.
