In the new era when the automotive industry is moving towards personalization and functionalization, windshield sealing strips have been upgraded from traditional standardized parts to customized components that adapt to diverse needs. With its deep technical accumulation and flexible production capabilities, Hengcheng Factory has built a customized windshield sealing strip development system covering all scenarios, providing global customers with precisely matched solutions.
Hengcheng customization capabilities stem from a multi-dimensional response to market demand. In the field of materials, based on the basic EPDM formula, the factory has developed special rubber compounds such as conductive, chemical corrosion resistant, and ultra-low temperature brittle, to meet the needs of special scenarios such as polar vehicles and new energy battery compartments. According to the structural characteristics of different models, the parametric design system is used to quickly generate variable-section sealing structures that adapt to curved glass, or integrate aerodynamic components such as drainage grooves and wind guide wings, taking into account both functional and aesthetic needs. In the face of the popularization of intelligent driving technology, the factory innovatively embeds electromagnetic shielding layers and sensor wiring channels in the sealing strip to ensure that signal transmission is not interfered with, expanding the added value of windshield sealing strips.
The flexible production system is the core guarantee to support the implementation of customization. Hengcheng modular production line can seamlessly switch between the production of windshield sealing strips of different specifications. The multi-cavity mold technology realizes the single vulcanization molding of composite structural sealing strips, which not only improves efficiency but also avoids the sealing risks of split assembly. The intelligent visual inspection system compares the 3D design model in real time, accurately captures the contour deviation of the special-shaped windshield sealing strip, and ensures the millimeter-level fit with the car body. Through the digital production platform, customized orders can be traced from order receipt to delivery, and the delivery cycle is significantly shortened compared with the industry average, meeting the rapid iteration of the development rhythm of car companies.
In response to the personalized needs of emerging markets, Hengcheng has created a variety of scenario solutions. The dynamic sealing system of the convertible sports car adopts a segmented pressure adjustment structure to balance the smoothness of opening and closing and air tightness under high-speed wind pressure; the heavy-duty sealing strips dedicated to electric trucks use the wear-resistant coating technology on the contact surface to increase the service life to several times that of traditional windshield sealing strips; the invisible sealing solution for high-end models uses optical-grade surface treatment technology to achieve a seamless visual transition between glass and body. These innovative achievements not only solve the pain points of specific scenarios, but also redefine the technical boundaries of windshield sealing strips.
The in-depth extension of technical services further enhances the value of customization. Hengcheng technical team has been involved in development since the conceptual design stage, using fluid mechanics simulation technology to predict the impact of different climates on sealing performance and optimize the material expansion coefficient in a targeted manner. Relying on the structural parameters stored in the global vehicle database, the adaptation plan of the modified vehicle model can be quickly matched. For special assembly requirements, the factory provides on-site compression molding services, and completes the one-piece molding of special-shaped sealing strips directly on the customer’s production line, breaking through the limitations of traditional logistics and assembly.
In the context of rapid iteration of the automotive industry, Hengcheng continues to expand the boundaries of customization by building an agile response chain of “design-verification-production”. From the dynamic sealing of the smart cockpit to the edge packaging of the solar canopy, each windshield sealing strip carries a deep understanding of user needs. We always believe that only by deeply integrating technological innovation with scene insights can we create a sealing solution for modern cars that truly fits its soul.
