How Sumiparts Executes High-Volume Plastic Extrusion
Sumiparts SAS plastic extrusion is a process that presents high productivity and is one of the most important for obtaining plastic shapes in volume. Sumiparts has the equipment, tools and qualified personnel to carry out this operation, which is very simple, once the conditions have been established of operation. The extrusion of rigid and flexible plastics of Sumiparts SAS, consists of giving a defined shape to the plastic through the use of pressure, thrust and temperature.
The material that is supplied to the machine is loaded through the use of a container in the upper part of the extruder called a hopper, which uniformly deposits the material inside the screw, later it will be subjected to temperature and fusion, in order to thus push this material into the cavities of the mold and obtain our profile or packaging footage to the desired size.
Uses in the plastic extrusion market
The extrusion of rigid and flexible plastics is a highly demanded market line which must provide the market for profiles, coatings and finishes, products that meet the needs of individual and / or general projects
We specialize in the development of extruded profiles, with established market lines and line products, we also have new development lines where it is executed:
Manufacture of molds for rigid extrusion
Manufacture of molds for flexible extrusion
The Sumiparts plastic extrusion process, It is an efficient method of manufacturing profiles and semi-finished products, or also known as shapes, with large wall thicknesses and dimensions.
The inventory of products and semi-finishes goes from the creation of hoses, tubes, sheets, shutter sheets, windows, water flow channels, filaments, save brooms, among others.
With Sumiparts the plastic extrusion process has several advantages, such as the variety of
shapes, lower costs, lighter parts and products, and high productivity, efficiency and quality.

Advantages of Plastic Extrusion
High Efficiency: Continuous operation allows large-volume production with minimal downtime.
Design Flexibility: Complex profiles with consistent dimensions can be created.
Cost-Effectiveness: Efficient use of material reduces waste.
Lightweight and Durable Components: Extruded plastics provide strength without excessive weight.
Customizability: Color, material type, and mechanical properties can be tailored to requirements.
These advantages make plastic extrusion a go-to method for producing functional and aesthetic components in industries ranging from automotive and construction to consumer goods and electronics.
Common Applications of Extruded Plastics
Plastic extrusion enables the production of a wide variety of products, including:
Pipes and tubing for plumbing, chemical transport, or air ducts
Window and door profiles for construction
Protective casings for electrical cables
Custom shapes for automotive or industrial assemblies
Consumer goods such as plastic rods, sheets, and trims
The versatility of extrusion allows manufacturers to meet both mechanical performance requirements and aesthetic standards, ensuring components are reliable, durable, and visually appealing.
Tips for Optimizing Plastic Extrusion
Select the Right Material: Consider mechanical, thermal, and chemical resistance properties.
Optimize Die Design: Proper die engineering prevents defects like warping or uneven thickness.
Control Process Parameters: Temperature, screw speed, and cooling rate directly affect dimensional accuracy and surface finish.
Implement Quality Control: Inline monitoring, surface inspection, and regular calibration ensure consistent production quality.
Material Mastery: Processing High-Performance Thermoplastics
The ultimate field durability of an extruded profile depends entirely on polymer rheology and compound stability. Our extrusion division processes a wide spectrum of commercial and engineering-grade resins:
Rigid & Flexible PVC (Polyvinyl Chloride): The foundation of architectural window profiles, structural conduits, and chemical-resistant industrial hoses. We process specialized formulations featuring targeted UV stabilizers and impact modifiers.
ABS (Acrylonitrile Butadiene Styrene): Valued for its exceptional impact toughness, structural rigidity, and dimensional stability, making it ideal for heavy-duty automotive trim, appliance housings, and protective edge guards.
Polycarbonate (PC) & PMMA (Acrylic): Engineered for lighting diffusers, sight glasses, and optical biosecurity channels, requiring crystal-clear transparency paired with strict thermal resistance.
Engineered Elastimers (TPE / TPU): High-flexibility polymers processed for custom gaskets, flexible bellows, and vibration isolation dampening strips that resist environmental oil exposure.
Advanced Processing Capabilities: Co-Extrusion and Multi-Material Geometry
Modern industrial designs frequently require a single profile to perform multiple mechanical functions simultaneously. To address this without requiring secondary manual assembly, the Sumiparts facility utilizes advanced dual-durometer and tri-extrusion technology.
By routing distinct molten polymers from independent satellite extruders into a single, unified cross-sectional die, we combine rigid and flexible elements seamlessly. This allows us to manufacture complex architectural seals featuring a rigid structural polypropylene base that clips effortlessly into aluminum framing, bonded directly to a soft, flexible TPE bulb that compresses perfectly to form an airtight, watertight barrier. This integrated manufacturing loop reduces your assembly labor and eliminates the risk of layer delamination under extended field operations.
End-to-End Inline Secondary Fabrication
The Sumiparts high-efficiency extrusion lines are engineered as fully integrated, automated downstream systems. We don’t just extrude raw plastic shapes; we deliver turnkey, drop-in components directly to your assembly floor via automated inline processing modules:
Precision Flying Cut-Offs & Saws: Programmable cutting heads that shear or saw profiles to exact linear lengths down to fractional tolerances without crushing or deforming the hot hollow geometry.
Inline Punching & Notching: High-speed pneumatic stations that stamp mounting holes, slots, or custom registration tabs into the profile while it travels continuously along the conveyor bed.
Automated Adhesive Application: Applying high-bond acrylic or rubber-based double-sided tapes (PSA) directly onto specified profile faces mid-production for immediate peel-and-stick installation.
Conclusion
Plastic extrusion is a highly versatile and efficient method for producing durable components with precise dimensions. By combining the right materials, optimized machinery, and skilled operation, manufacturers can create products that meet both performance and aesthetic requirements.
From custom profiles to standardized pipes and tubes, plastic extrusion continues to be a cornerstone in modern industrial production, delivering reliable and cost-effective solutions across multiple sectors.
