Top Aluminum Alloy Door & Window Sealing Strips Manufacturer | OEM/ODM Custom Solutions
When you are sourcing sealing strips for aluminum alloy doors and windows, you need more than a commodity supplier. You need a manufacturing partner who understands how the seal integrates with the frame, the thermal break, and the hardware. At Jusen Doors & Windows Manufacturing Co., Ltd., we are not a trading company that resells generic strips. We are a professional solid wood door and aluminum window manufacturer with 20 years of experience, producing high-end custom doors and windows for global contractors, interior designers, retail dealers, and villa real estate developers. Our sealing strips are engineered as a critical component of our own finished window systems, and we offer full one-stop OEM & ODM customization service for your specific profiles.
This article explains how our factory, quality systems, and engineering support make us the right partner for your next project. Whether you need a standard EPDM bulb seal or a custom-designed thermal break gasket, we have the capability to deliver.
Aluminum Alloy Door & Window Sealing Strips We Manufacture
Our product range covers every common sealing application for aluminum windows and doors. Because we also manufacture the frames and hardware, we understand the precise tolerances required for a perfect fit.
Weatherstripping for Casement & Tilt-and-Turn Windows
For casement and tilt-and-turn windows, we manufacture compression seals, bulb seals, and fin seals using EPDM, silicone, TPE, and PVC. Our factory produces seals that withstand extreme weather conditions, from -40°C to +120°C. This is backed by our self-built workshops where we control every variable, from rubber mixing to final cutting. We have seen many generic strips fail after one season because they were not formulated for UV exposure or ozone resistance. Our materials are tested in-house to ensure they meet the demands of global construction projects.
Sliding Door & Window Sealing Solutions
Sliding systems present unique challenges: large openings, dust ingress, and air leakage. We manufacture brush seals, wool pile, and dual-fin EPDM strips specifically designed for sliding doors and windows. Our team works closely with global contractors and villa real estate developers who require high-performance sliding systems for luxury residences. We can match the color and hardness to your aluminum profiles, ensuring a seamless aesthetic and reliable performance.
Custom Profiles for Thermal Break & Insulated Glass Units
Beyond basic weatherstripping, we produce spacer bars, structural glazing gaskets, and thermal break strips. These components are critical for energy efficiency and condensation control. Our OEM service includes custom die development for unique aluminum profiles. If you have a proprietary frame design, send us your drawing, and our independent design team will create a sealing solution that integrates perfectly.
Our Factory: Where Precision Meets Mass Production
B2B buyers need to know that their supplier has the physical capacity to deliver on time, every time. Our factory is the backbone of our reliability.
Workshop & Production Line Scale
We own self-built wood drying, spraying, and aluminum processing workshops. For sealing strips, our dedicated aluminum processing workshop houses multiple extrusion lines and assembly stations. This vertical integration means we do not outsource critical steps. We control the rubber mixing, extrusion, vulcanization, and cutting under one roof. This is how we maintain stable quality across millions of meters of sealing strips each year.
Annual Output & Flexible MOQ
Our annual production capacity is measured in millions of meters. However, we understand that not every order is a bulk shipment. We offer flexible MOQ — we support small pilot runs for interior designers testing a new profile, as well as massive bulk orders for construction project supply. Whether you need 500 meters for a custom villa or 50,000 meters for a high-rise development, we can accommodate your timeline.
Advanced Equipment & Technology
Our machinery includes automatic rubber extruders, high-frequency vulcanizers, CNC cutting machines, and cold-feed extrusion lines. But equipment alone is not enough. Our 20 years of processing experience ensures that our machinery is operated by master technicians who understand the nuances of rubber and silicone. They can adjust parameters on the fly to correct for material variations, ensuring consistent quality from the first meter to the last.
Rigorous Quality Assurance for Global Standards
Product failure is expensive. Failed seals mean callbacks, water damage, and reputational risk. We take quality seriously because our own window systems depend on it.
In-House Material Testing
We own the testing equipment in our factory to guarantee stable quality before shipment. Every batch of material is tested for tensile strength, elongation, compression set, and temperature resistance from -40°C to +120°C. We do not rely on supplier certificates alone. Our quality control team runs these tests in-house, and if a batch fails, it is rejected before it ever reaches the extrusion line.
Dimensional & Adhesion Verification
A seal that is 0.5 mm too thick will not compress properly. A seal that is too thin will rattle. Our quality control team works alongside our independent design team to ensure the seal matches the frame geometry exactly. We use digital calipers and profile gauges to verify dimensions on every production run. For adhesive-backed strips, we test peel strength to ensure the strip will not detach during installation or in hot weather.
Certifications & Compliance
We comply with international standards, including ISO and SGS testing protocols. Additionally, we provide a full shipping damage after-sales guarantee. If the seals fail due to our manufacturing defect, we replace them at no cost. This guarantee is not just a promise — it is a reflection of our confidence in our own production process.
Full Customization: OEM & ODM Sealing Strip Manufacturing
Most buyers searching for an “aluminum alloy door and window sealing strips manufacturer” are looking for a partner who can handle custom work. That is our core competency.
Private Label & Branding
We offer Private Label services, allowing you to sell our high-quality strips under your own brand. We can print your logo, part numbers, and specifications on the packaging or directly on the strip. This is ideal for retail dealers and distributors who want to build their own product line without investing in manufacturing.
Custom Size, Color & Hardness
Whether you need a custom design for a unique wooden door frame or a standard aluminum window seal, we can produce it. We match RAL colors, durometer (Shore A hardness), and specific cross-section designs. If you have a physical sample or a 2D drawing, we can reverse-engineer it. Our factory can produce strips in a wide range of colors and hardness levels, from soft silicone (Shore A 30) to rigid EPDM (Shore A 80).
Engineering Support & Rapid Prototyping
Send us your profile drawing, and our team will provide customized construction drawings and a formal quotation within 24 hours. This rapid response is possible because we own our independent design team and self-built workshops. We do not wait for external contractors. Mold development and sample production typically take 7-15 days, depending on complexity. Once approved, we move to mass production with the same molds and parameters.

Q: What materials do you use for aluminum alloy door and window sealing strips?
We primarily use EPDM (Ethylene Propylene Diene Monomer) for its excellent weather resistance, but we also offer silicone, TPE, and PVC depending on the application. As a manufacturer with 20 years of experience, we can recommend the best material for your climate. For example, silicone is preferred for extreme cold, while EPDM offers superior ozone resistance for hot climates.
Q: Can you match a specific color to my aluminum window frames?
Yes. We offer full OEM service including color matching. You can provide a RAL code or a physical sample. Our factory can produce strips in a wide range of colors and hardness levels. We have matched colors for luxury villa projects where the seal must be invisible against the frame.
Q: What is your minimum order quantity (MOQ) for custom sealing strips?
Our MOQ is flexible. We understand that retail dealers and interior designers may need smaller runs for custom projects, while villa developers need bulk supply. We can accommodate both scenarios. For standard profiles, MOQ can be as low as 500 meters. For custom molds, we require a minimum order to cover tooling costs, but we work with you to find a solution.
Q: How long does it take to develop a new mold and start production?
Because we own our independent design team and self-built workshops, we can move fast. Typically, we can provide a customized construction drawing and formal quotation within 24 hours. Mold development and sample production usually take 7-15 days. Mass production begins immediately after sample approval.
Q: Do you have overseas warehouses to reduce shipping time?
Yes. We have North America overseas warehouses, which significantly reduces lead time and shipping costs for our clients in that region. We also offer a full shipping damage after-sales guarantee for all exports. If your order arrives damaged, we replace it.
Q: How do I send an inquiry for a specific profile?
You can Contact Our Team directly through our website. Please attach a drawing, a sample photo, or the dimensions of your aluminum profile. We will review it and provide a formal quotation within 24 hours.
