In Mold Graining

The In-Mold Graining (IMG) process, a vacuum-forming technique, efficiently textures leather and bonds injection-molded plastic parts at once, making it cost-effective and widely used in crafting automotive and aviation interiors like instrument panels and door trims.

TDL:Leading Company of In Mold Graining in China!

Commencing its journey in in-mold graining (IMG) tool creation back in 2008, TDL has since established a robust portfolio of successful IMG initiatives aimed at enhancing automotive interiors. Serving manufacturers within the automotive interior parts sector, we’ve demonstrated our proficiency in delivering meticulously grained pieces where the leather covering can possess a thickness of up to 3.5mm, thus ensuring a soft-touch surface.

By applying nickel shell mold graining, we’re capable of delivering sophisticated vehicle interior components, including instrument panels and door trims. These products not only possess a pleasant tactile sensation but are also crafted with a strong commitment to environmental responsibility and efficiency.

Aligning with TDL for your automotive interior parts production means partnering with a company that’s not just a service provider, but a valuable tool in your manufacturing process, dedicated to one-stop solutions that consistently deliver quality and efficiency.


TDL In-Mold Graining (IMG) Capabilities

Explore the in-mold graining (IMG) technology with TDL: Your trusted partner for automotive applications.

Automotive Low Pressure Injection Molding Manufacturing

The mold cost and equipment investment are less than IMG manufacturing and Lamination wrapping production. While the thickness of the leather cover is thin, around 0.8-1.2mm, the instrument panel’s touch feeling is not very soft.

IMG is high efficiency, and the thickness of the cover can be 3.5mm or more. The material is TPO, PVC, TPO+ PP FOAM, etc. The soft-touch feeling is better than low-pressure injection molding parts. Most used for IP parts manufacturing.

Hot Pressing (Lamination Wrapping) Automotive Trims Manufacturing

Leather wrapping can be automatic or manual. The thickness of the leather cover is 3.5mm or more, which means the soft touch is better. And materials of the cover are various, PU, TPO, FOAM+PU, PVC, 3D MESH, etc.

IMG-S (In Mold Grain-Skin): It is a smooth film material that uses a mold engraved with a grain pattern to create a skin in the shape of an automotive interior with a grain. Before laminating the skin to the injection molded parts, workers can stitch patterns on it.
IMG-L (In Mold Grain-Laminate): It uses a mold engraved with a leather pattern to form textured skin in the shape of an interior part from a smooth film material. Then laminates the skin to the injection molded plastic parts by vacuum adsorption. IMG-L equipment has low investment and high efficiency, and the skin used differs from IMG-S.

IMG technology is widely used in the car door trim, instrument panels, and IP trims. The injection molded parts in contact with people are covered with soft skin. This flexible design can improve the car’s decorative effect and the sound and heat insulation effect of the vehicle, thereby improving the comfort and safety of the occupants in the car.
