Plastic Profiles Produced on This Line
PVC Track and Guide Profiles (Pellet Compound)
Transparent or colored track and guide profiles manufactured from pelletized PVC compound, widely used in electrical installations, sliding mechanisms, and interior decoration. The line is specially configured around optical clarity, snap-fit precision, and required dimensional stability.
ABS Protection and Decorative Profiles
Medical corridor wall guards, corner trims, and high-gloss visible components. The die and cooling path are precisely matched to maintain tight tolerances and consistent surface finish across extended production runs.
PC, TPE, PS Flexible and Sealing Profiles
Elastic strips, seals, and soft-touch profiles requiring surface clarity and dimensional stability. Non-stick sizing surfaces and gentle homogenization effectively reduce drag marks and air entrapment on soft, high-clarity compounds during extrusion.
PP and PE Industrial Profiles
Structural and functional profiles achieving shrinkage control and shape stability in continuous production. Extended cooling sections and reduced haul-off contact pressure effectively manage the high post-cooling shrinkage characteristic of polyolefin materials.
Co-Extruded Composite Profiles
Dual-color, cap-layer, or soft-rigid structures realized when material compatibility and product design permit. Co-extrusion dies and layer ratio parameters are specifically reviewed for each compound pair.

PP, PE, ABS, PC, TPE, PS, and selected PVC pellet compounds can all be processed on a single screw precision profile extrusion line. However, each resin possesses a distinct processing window and specific profile defect patterns requiring targeted management.
Precision Plastic Profile Extrusion Process
01 — Material Feeding and Preparation
PP, PE, ABS, PC, TPE, PS, or selected PVC pellet compound is fed according to resin grade specifications. Hygroscopic resins such as ABS and PC, TPE, PS require desiccant drying before extrusion to eliminate moisture-related surface defects.
02 — Single Screw Plasticizing and Melting
The single screw extruder melts and conveys resin with controlled shear and temperature. Screw geometry, compression ratio, and temperature profile are matched to the compound to ensure stable, uniform melt delivery.
03 — Profile Die Forming
Melt enters a profile die matched to the product drawing. Die flow paths are engineered around cross-sectional shape and wall thickness distribution for balanced melt delivery and dimensional stability.
04 — Sizing — Free-Sizing or Vacuum Calibration
The hot profile is sized by the method selected for its geometry and surface sensitivity: Free-sizing (direct-to-water cooling for contact-sensitive surfaces) or Vacuum calibration (calibrator with vacuum tank for hollow or complex profiles requiring strong shape lock).
05 — Cooling
The profile continues through water cooling to solidify the cross-section before traction. Cooling length and water coverage are determined by material, profile size, and line speed; semi-crystalline PP and PE typically require longer cooling paths.
06 — Synchronized Haul-Off
The haul-off pulls the profile at a steady speed synchronized with extruder ouPC, TPE, PSt. Belt or caterpillar traction is selected based on profile rigidity and surface sensitivity, with optimized contact pressure ensuring sizing without imprinting.
07 — Cutting and Stacking
The cutting unit cuts profiles to required length using saw, rotary, or guillotine cutting matched to material rigidity, wall thickness, and target length. Take-off and stacking systems ensure finished profiles without surface damage.
Optional Configurations: Mobile co-extruder for dual-color, cap-layer, or soft-rigid structures; Protective film applicator for high-gloss profile surface protection.

Key Quality Points for Precision Plastic Profiles
Surface Finish
Gloss or textured profiles are sensitive to die marks, melt instability, moisture, and downstream scratches. Deerma Machine reviews die polishing, temperature control, drying, and profile handling before quotation.
Dimensional Stability
Vacuum calibration (or free-sizing), cooling coverage, and haul-off speed must work together to maintain the drawing-defined cross-section. PP and PE require extended cooling and lower haul-off contact pressure to manage post-cooling shrinkage.
Material-Specific Defects
Each resin brings its own defect pattern: PP and PE (shrinkage and warping); ABS (silver streaks from moisture or brittleness from excessive shear); PC, TPE, PS (drag marks and bubbles); Co-extrusion (delamination at soft-rigid interfaces). Screw geometry, temperature strategy, and drying are matched to the compound to manage these defects.
Scratch-Free Handling
Glossy PVC, ABS, and PC, TPE, PS profiles can be rejected if the visible surface is scratched. Guided haul-off, clean support surfaces, and optional film application help protect the finished profile during collection, packing, and shipping.
For precision profiles, the line is reviewed around surface finish, dimensional stability, material-specific behavior, and scratch-free handling before quotation.

FAQ — Precision Plastic Profile Extrusion Lines
Q1: When should a plastic profile line use a single screw extruder instead of a twin screw extruder?
A precision single screw plastic profile extrusion line is normally used for pellet materials such as PP, PE, ABS, PC, TPE, PS, and selected PVC pellet compounds. It is suitable when the project depends on stable melt delivery, profile die matching, surface finish control, and downstream sizing rather than powder-compound processing. Twin screw systems are more commonly used for PVC powder compound and rigid PVC window or door profile production.
Q2: What materials can this precision plastic profile extrusion line process?
This precision plastic profile extrusion line can process PP, PE, ABS, PC, TPE, PS, and selected PVC pellet compounds when the line is configured around the resin grade, drawing, tolerance, surface finish, and sizing method. The screw geometry, temperature profile, drying requirement, cooling path, haul-off contact, and cutting method are reviewed according to material behavior and finished profile use.
Q3: How are PVC pellet compound profiles configured?
PVC pellet compound profiles are configured as single screw extrusion projects for track, guide, electrical, and interior profiles, not as PVC powder window or door profile lines. Free-sizing or vacuum calibration is selected according to profile geometry, while glossy track and guide profiles may need careful die polishing, cooling support, haul-off contact control, and scratch-conscious downstream handling.
Q4: How are PC, TPE, PS flexible profiles handled during extrusion?
PC, TPE, PS flexible profiles are handled with moisture control, gentle plasticizing, and low-friction downstream contact because PC, TPE, PS is sensitive to bubbles, drag marks, and deformation. For soft PC, TPE, PS grades, the line can use non-stick sizing surfaces, soft-touch haul-off, and chipless cutting to reduce surface marks and profile distortion during traction and cutting.
Q5: How do PP and PE profiles control shrinkage and warping?
PP and PE profiles control shrinkage and warping through die compensation, longer cooling paths, stable cooling coverage, and haul-off pressure matched to profile shape. Because PP and PE are semi-crystalline materials with post-cooling shrinkage, the line is configured to reduce temperature gradients, dimensional drift, and surface imprinting during continuous production.
Q6: How do ABS profiles keep gloss and impact strength?
ABS profiles maintain gloss and impact strength through melt homogeneity, precise temperature control, suitable screw geometry, and drying when the resin or surface requirement needs it. A desiccant dryer can help reduce silver streaks or splay marks from moisture, while controlled shear helps avoid degrading the butadiene rubber phase that gives ABS its impact resistance.
Q7: What information is needed before quotation?
Before quotation, Deerma Machine needs a profile drawing or sample photo, resin grade, profile size, wall thickness, tolerance, surface requirement, line speed or daily production target if available, cutting length, packing requirement, and factory voltage. Co-extrusion, straightening, film protection, cooling water, and layout limits should also be shared when they affect the final line configuration.
