瀬川化学工業 Company Profile

We are experts in soft injection-molded resin products, including weatherstrips.

Our company has been manufacturing automotive parts through resin molding for over 60 years. In particular, we have a strong reputation in the field of injection molding of soft resins, such as automotive weather strips, with our weather strip products being installed on more than 1.2 million vehicles annually (including rear quarter windows and front fixed windows). In recent years, the freedom of design has increased, leading to more complex shapes and a demand for more advanced molding technologies. However, we respond flexibly and supply products that satisfy our customers.
