A Custom Shape Thermal Break Strip is a non-standard polyamide insulation profile produced for aluminum systems with specific cross-sectional requirements. Unlike standard thermal break strips, its geometry is developed around the actual aluminum extrusion, including groove position, locking areas, profile depth, and other dimensional constraints.
Jinxing provides custom thermal break strip development for aluminum profile manufacturers, door and window producers, curtain wall suppliers, and engineering projects requiring a profile that cannot be matched by conventional strip shapes.
The main value of a custom thermal break strip is not simply changing its width or length. The entire cross-section can be developed around the aluminum profile.
Depending on the application, the profile may require:
· Non-standard locking edges
· Offset or stepped sections
· Asymmetrical geometry
· Different wall thicknesses
· Special groove-matching structures
· Combined or irregular cross-sections
This allows the strip to follow the actual geometry of the aluminum extrusion instead of forcing a standard profile into an unsuitable groove.
The cross-section is developed according to the mating aluminum profile, allowing critical dimensions and locking areas to be positioned where they are required.
For aluminum extrusions with irregular or specially designed grooves, a Custom Shape Thermal Break Strip can provide a closer dimensional match than a standard thermal break strip.
During extrusion, Jinxing controls the forming and cooling process according to the specific geometry of the profile, helping maintain consistent dimensions across production batches.
The thermal break profile can be produced with specified material grades, hardness requirements, and colors according to the customer's project requirements.
Custom thermal break strip production normally follows a development process:
Drawing / Sample → Section Review → Tooling Development → Trial Extrusion → Dimension Adjustment → Mass Production
Before tooling, Jinxing reviews the critical dimensions of the proposed section, including the overall profile size, insertion areas, locking geometry, and contact points with the aluminum extrusion.
Trial production can then be used to verify the actual section before moving into regular production.
Jinxing mainly produces Custom Shape Thermal Break Strip using PA66 GF25, where PA66 is reinforced with 25% glass fiber.
For customized sections, material selection needs to consider not only the basic thermal insulation function but also the geometry of the profile and the mechanical forces encountered during insertion and aluminum profile assembly.
For a customized product, dimensional inspection focuses on the critical features of the cross-section, rather than checking only the overall width and thickness.
Jinxing can inspect profile dimensions, surface condition, section geometry, and relevant material properties according to the agreed specifications. Samples from trial and mass production can be compared with the approved drawing to maintain section consistency.
It is a thermal break profile with a non-standard cross-section developed specifically for an aluminum extrusion that cannot use a conventional insulation strip.
Yes. An aluminum profile drawing can be used to review the required strip geometry and develop the corresponding tooling.
Yes. A sample can be used as a reference for section development when complete technical drawings are not available.
Jinxing mainly uses PA66 GF25 for customized thermal break strips.
The cross-section can be developed according to the technical and manufacturing requirements of the aluminum profile. The final geometry is confirmed after reviewing the drawing, groove structure, and production feasibility.
Normally, a dedicated extrusion die is required when the requested cross-section differs from existing tooling.
Yes. Existing tooling or profile designs can be reviewed when customers need adjustments to dimensions or specific section features.
