Improve Your Existing Recycling Line Performance

It is a retrofit solution combining continuous CDF melt filtration with a compact TA cascade extruder and vacuum degassing to expand the performance of an existing recycling line — raising throughput and pellet quality without replacing the whole line.

Potentially. Feasibility depends on accessible technical data, mechanical and control interfaces, equipment condition, safety/compliance, available space, utilities, capacity and remaining life. An audit is required; some lines may be unsuitable or uneconomical to retrofit.

If the problem comes from material preparation, recipe, temperature, screen practice, maintenance, vacuum leakage, worn parts, controls or operating discipline, correction may restore performance without a major retrofit. Compare this first.

There is no standard package. Depending on the proven constraint, scope may include preparation/feeding, CDF filtration, vacuum or TA cascade degassing, pressure build-up, pelletising, controls, conveying or utilities. Include only justified components.

CDF may be relevant when measurable solid contaminants remain in the melt and continuous filtration supports the required fineness, pressure and throughput. Confirm contaminant type/load, rheology and discharge behaviour. It cannot solve incompatible polymers or every upstream-cleaning issue.

A project-specific melt-distribution and venting arrangement can renew melt surface and expose it to controlled vacuum before pressure build-up. Actual removal depends on polymer, temperature, residence time, moisture/volatile load, vacuum performance and configuration; it must be validated.

Provide equipment list/drawings, models and age, screw/barrel/drive condition, controls and interfaces, filtration/vacuum/pelletising data, maintenance and downtime history, process trends, material and variability, current/target throughput and quality, energy/consumables, utilities, available space and production constraints.

Downtime depends on scope, interfaces, prefabrication, site access, utilities, controls, testing and contingency. MAS should provide a project-specific installation and restart plan with responsibilities, critical path, assumptions and a downtime range—not a universal duration.

Cost drivers include audit/testing, engineering, equipment, controls, interfaces, wear repairs, utilities, installation, downtime, commissioning and training. Payback also depends on throughput, usable yield, output value, energy, consumables, labour, maintenance and avoided replacement. Compare lifecycle scenarios with the same assumptions.

It can when the modified stage is the proven throughput bottleneck and upstream/downstream equipment can support the increase. A filter or degassing upgrade cannot overcome limits in feeding, drive power, cooling, pelletising, conveying or utilities. State the validated range and remaining constraints.

Not automatically. Energy per kilogram may improve, remain similar or increase depending on added equipment, throughput, material and operating window. Compare measured baseline and projected/validated total-line energy under equivalent output criteria.

Agree representative material, baseline, configuration, operating conditions, sampling and test methods. Verify throughput, stability, output quality and any energy, yield, maintenance or downtime criteria stated in the contract. Document scale-up assumptions and exclusions.

The audit should identify likely upstream and downstream constraints, but increasing one stage’s capacity can expose another limit. The proposal should state residual risks, retained-equipment capacity and staged follow-up options.

Replacement may be better when existing equipment has insufficient capacity or remaining life, unavailable spares/data, incompatible controls or interfaces, severe wear, safety/compliance issues, multiple bottlenecks or retrofit lifecycle cost and downtime approaching a new-line case.

Any guarantee must define material specification and variability, retained and new equipment, operating conditions, utilities, test methods, throughput/output criteria, exclusions, responsibilities and acceptance procedure. It cannot be universal across unknown materials or line conditions.
