Twin-Screw Extruder Technology
CTE’s non-intermeshing, counter-rotating twin-screw extruders
deliver higher throughput, lower energy use, and fewer defects
— helping manufacturer improve profitability.

High shear heat → more cooling energy needed
In co-rotating intermeshing extruders, material is forced through kneading discs under high compression. This generates excessive frictional heat, causing the resin temperature to rise rapidly. To compensate, more cooling energy is required, which will lead to increasing monthly electricity costs.
10–20°C lower resin temperature through compression-release kneading
CTE’s patented rotor design uses a grinding-like process that reduces localized shear. The compression-release cycle controls heat generation, achieving resin temperatures 10–20°C lower than conventional systems, reducing the cooling and energy costs.
Poor degassing → air bubbles in pellets → rejected batches
In intermeshing twin-screw extruders, the screws interlock tightly, leaving no pathway for air and gas to escape. This trapped gas creates bubble defects inside pellets — a major cause of molding defects. Every rejected batch means wasted material, labor, and revenue.
Non-intermeshing design enables exceptional gas venting
CTE’s non-intermeshing counter-rotating design maintains a gap between screws. Gases vent smoothly through the exhaust port, preventing air bubbles in pellets and eliminating a major source of production waste.
Must reduce screw speed to prevent thermal degradation
When excessive heat builds up during kneading, operators must lower screw speed to avoid thermal degradation — directly reducing throughput. Combined with feed-neck phenomena caused by poor degassing, this creates bottlenecks that hinder production capacity.
No need to reduce speed — stable high-throughput operation
CTE’s low heat generation eliminates the need to reduce screw speed. Its excellent degassing prevents feed-neck issues. The result: throughput volume approximately double that of conventional co-rotating extruders.*
When you factor in energy savings, waste reduction,
and increased throughput — CTE extruders deliver
a lower total cost of ownership.
CTE’s patented technology addresses the three biggest cost drivers in compounding operations.

Frequently Asked Questions
Q1. What is your price range and ROI estimate?
CTE’s extruder specifications vary depending on raw material conditions, production objectives, desired quality, and volume. Therefore, we do not have a uniform price or ROI estimate in advance. After a detailed hearing about your specific requirements, we propose pricing and cost-benefit estimates based on the optimal configuration for your operation.
Q2. How long does delivery take?
Delivery depends on model and specifications. For extruders, the standard is approximately 6 months or more after order. A detailed delivery schedule is confirmed after specifications are finalized.
Q3. What after-sales support do you provide?
CTE provides comprehensive post-installation support:
- Maintenance support after installation
- Guidance on operating methods and conditions
- Technical support in case of trouble
*Support details and complimentary period vary depending on contract terms.
Q4. What is the process after inquiry?
❶ Understanding your needs — We confirm your requirements based on your inquiry.
❷ Consultation — Detailed hearing on raw material conditions and targets.
❸ Testing — Send us your raw materials and CTE will conduct testing.
❹ Results — Test results shared as a report. Retesting available as needed.
❺ Proposal — Optimal model, specifications, and conditions proposed.
Q5. How does CTE compare to conventional co-rotating extruders?
CTE’s non-intermeshing, counter-rotating design offers fundamental advantages:
- Superior degassing — gaps between screws allow gas to vent, preventing bubble defects
- 10–20°C lower resin temperatures — compression-release kneading reduces shear heat
- Approximately 2× throughput* — no need to reduce speed for thermal management
- Better dispersion — Banbury-mixer-level kneading with patented rotors
*Based on comparison at screw diameter 40 mm, CTE data.
Q6. Are there government incentives in Thailand / Indonesia?
Yes. Thailand’s BOI offers import duty exemptions on machinery and CIT exemptions for up to 8 years. Indonesia provides capital goods import duty relief, KEK tax reductions, and other manufacturing incentives. Our team can provide guidance on applicable programs at no extra charge.
