People’s pursuit of sensory enjoyment has never stopped. Under the digital new energy boom, new demands for color, touch, and intelligence in automotive accessories are also constantly calling for processes and products with higher expressiveness.
Material solutions enhance appearance
Crystal clear and translucent surface, various textures and diverse colors with a strong sense of design. How to achieve these appearances?
Wanhua Chemical relies on its advanced R&D platform and integrated industrial chain to develop a polyurethane in-mold molding material solution—Surface-form.
Pro. The polyurethane material is injected into the mold, and the resulting product has excellent properties such as high light transmittance, high gloss, scratch resistance, and self-healing. It has a high degree of design freedom and can realize colorful and textured appearances, touch surfaces, and ambient lights. It has excellent effects in automotive decorative parts such as instrument panels, door panels, and central control panels.
Advanced technology supports terminal applications
In-mold painting technology is the process path for Surface-form Pro product technology to reach end products, and has received widespread attention from the industry in recent years.
Compared with traditional processes, in-mold painting technology simplifies multi-layer spraying, baking and other processes, and is more in line with the automotive industry’s continuous pursuit of low-carbon and environmental protection. At the same time, the mold is used to present different appearance effects, has strong plasticity, and solves the problem of spraying. The industry’s difficulty in achieving three-dimensional pattern effects has added new vitality to the high-end and technological performance of automotive accessories.
The combination of Surface-form Pro and the in-mold painting process enables fully automated manufacturing with a high degree of design freedom and significant cost-effectiveness.
Multi-dimensional services empower diverse designs
Relying on the group’s advanced technology platform, Wanhua Chemical can assist customers in conducting CAE simulations and mold flow analysis to ensure the smooth realization of process design; combined with CMF aesthetic appearance development, Wanhua Chemical can provide industrial aesthetic design thinking to meet more personalized needs. ; At the same time, relying on the advantages of the industrial chain, combined with modified PC, etc., it provides overall material solutions for the industry.
