PET Molded Automotive Felt

The LMPET proportion can be adjusted from 15% to 50%. The melting point of the low-melting fiber ranges from 110 to 180°C.

During production, mold temperature can be set within approximately 10°C above or below the melting point of the selected low-melting fiber. Temperature-control accuracy can reach ±3°C.

The material can be formed by a cold-material hot-mold process or heated quickly and evenly with high-pressure steam. The maximum forming depth is about 300 mm.

For products that include mounting clips, metal brackets, or plastic connectors, inserts can be positioned in the mold before forming. The PET felt and inserts can then be integrated during the same process.

This approach can reduce later assembly operations and improve dimensional matching around the inserted parts.

Different functional layers can be combined during molding. Available structures may include PET rigid felt, PET soft felt, PE or PE-PA bonding film, EVA or TPU sound-barrier film, aluminum foil, nonwoven fabric, needle-punched carpet, tufted fabric, leather, or PVC film.

These layers can create an integrated structure for support, sound insulation, sound absorption, thermal reflection, and surface decoration.

A door-panel substrate may use 600–1,000 g/m² rigid felt combined with a surface fabric. A headliner acoustic layer may use 400–800 g/m² soft felt.

A main-carpet structure can combine a 600–1,200 g/m² rigid forming layer with a 400–800 g/m² soft acoustic layer at 10–20 mm thickness.

An outer wheel-housing part may use rigid felt with a basis weight of 800–1,200 g/m² and a density of 0.5–0.7 g/cm³.

The material does not easily become brittle at -40°C, and its long-term service temperature can reach 120°C. A single-material PET structure can also support 100% PET recycling.

Jiangsu Haokai has PET continuous-fiber and steam-molding production lines. The company can develop PET Molded Automotive Felt according to component depth, curvature, mounting-hole positions, inserts, and surface-layer requirements.

Production covers raw-felt manufacturing, molding, precision cutting, final inspection, and warehouse management. Custom samples normally require 10–15 days, and the reference production period is 7–15 days.

Repeat orders may be completed more quickly after the material, mold, and process parameters have been confirmed. Packaging can be designed around the curved surface, edges, and insert positions of the molded component.
