High‑temperature metal gaskets are sealing components engineered to withstand elevated thermal and pressure environments. Unlike
soft or elastomeric gaskets, these are made with metallic or metallurgical composite structures, offering:
* Superior thermal resistance (upwards of 400 °C / 750 °F, and beyond)
* Excellent chemical inertness and pressure integrity
* Stability against thermal cycling, creep, and compression set

SpecificationCNC Metal Heat Insulation Gasket Produce Processing
1. Raw Material Selection and Inspection Select metal substrates such as stainless steel and aluminum foil, matched with
insulation core materials like ceramic fibers and asbestos substitutes; conduct a full inspection on substrate thickness, core material insulation performance and temperature resistance grade, and reject unqualified raw materials.
insulation core materials like ceramic fibers and asbestos substitutes; conduct a full inspection on substrate thickness, core material insulation performance and temperature resistance grade, and reject unqualified raw materials.
2. Substrate Pre-treatment
The metal substrate undergoes degreasing → pickling and rust removal → water washing and drying → surface sandblasting in sequence to improve the surface roughness of the substrate and enhance the composite adhesion with the core material.
3. Core Material Cutting and Forming Cut the insulation core material into corresponding specifications of sheets with a cutting machine according to the gasket size requirements; for special-shaped gaskets, adopt die cutting or laser cutting processing.
4. Composite Pressing Stack the metal substrate and insulation core material in the structure of "metal layer - core material layer - metal layer", put them into a hot press, and complete the compounding under the set temperature, pressure and pressure holding time to ensure no hollowing or peeling between layers.
5. Integral Forming Processing According to the product drawings, process the composite sheet into the required gasket shapes (such as round, square, special-shaped parts with bolt holes) through stamping, CNC cutting or laser cutting, to ensure dimensional accuracy and edge flatness.
6. Edge Treatment and Sealing Grind the edges of the gaskets to remove burrs to prevent scratching the flange surface during installation; some high-demand products need to be coated with high-temperature resistant sealant on the edges or adopt metal edge wrapping technology to improve sealing and insulation performance.
7. Heat Treatment for Shaping Put the formed gaskets into an oven for low-temperature heat treatment to eliminate pressing stress, enhance structural stability, and ensure no deformation under high-temperature working conditions.
8. Quality Inspection
Conduct dimensional inspection (caliper, projector) → appearance inspection (no cracks, burrs) → insulation performance test (high-temperature thermal conductivity measurement) → pressure resistance and sealing test in sequence, and issue an inspection report.
9. Surface Treatment and Packaging The metal surface can be passivated or coated with anti-rust agent; classify them according to specifications, package them independently with moisture-proof films, and mark the product model, specification, batch number and temperature resistance parameters on the outer box.
