Hot melt extrusion equipment
Melt Extruder
Melt extruder for pharmaceutical hot melt extrusion, controlled release formulation trials, oral film process evaluation and scale-up planning.
Short Answer
A melt extruder processes powder or formulation blends through heated screw barrels to support hot melt extrusion, controlled release development and specialty dosage form evaluation.
Process position
Where A Melt Extruder Fits In The Process
The melt extruder is used after formulation blending or feeding and before downstream cooling, cutting, milling, granulation, film forming or collection.
Step 1
Blend feed
Step 2
Melting and mixing
Step 3
Extrusion
Step 4
Cooling or shaping
Step 5
Downstream sizing
Product data
What It Is And How It Works
Use this product data as a starting point for equipment selection. Final configuration should be confirmed against URS, material characteristics and testing where required.
What It Is
A melt extruder is a continuous thermal processing machine used to melt, mix and form pharmaceutical or specialty material formulations.
Working Principle
A metered feed enters heated screw barrels. The screw conveys, melts, mixes and pressurizes the formulation before it exits through a die or downstream process interface.
Material and sizing
Suitable Materials, Particle Size And Capacity
Particle size and throughput are process results, not generic promises. They depend on material behavior, selected model and operating parameters.
Suitable Materials
- Hot melt extrusion formulation blends
- Polymer-based controlled release systems
- Oral film and specialty dosage form materials
- Research samples for process feasibility
- Pharmaceutical excipient/API blends after thermal review
Target Particle Size / Control
Melt extrusion does not primarily target powder particle size. Final product form depends on screw configuration, die, temperature profile and downstream cutting, cooling or milling.
Capacity Range
Capacity depends on screw diameter, material behavior and process settings. Catalogue data covers lab through production models, with exact output confirmed by formulation testing.
