Automotive Lamp Housings
Lamp housings and covers for automotive lighting — balancing appearance, assembly fit and durability, with experience in black cosmetic and clear parts.
For more than three decades Dusun Plastics has focused on one thing: plastic injection molding. From tooling and trial runs to mass production, we deliver consistent, dependable parts through stable process conditions and disciplined quality control.
晟揚塑膠股份有限公司（Dusun Plastics Co., Ltd.） has been a dedicated plastic injection molding manufacturer since 1988, with its plant in Linkou District, New Taipei City, Taiwan.
We provide an integrated service covering tooling development, trial-run verification, mass production and final inspection. Three decades of process experience help customers validate faster in development and deliver steadily in production.
To us, the value of injection molding is not merely getting a part out — it is doing it the same way, every time. Consistency is the real cost advantage in mass production.
From a single tool to a production lot — every step, done steadily.
Stable molding conditions and disciplined process control keep appearance and dimensions consistent, lot after lot.
From tooling development and first trial (T-0) to production sign-off — helping customers hold the schedule and surface risks early.
Hands-on experience with commodity and engineering plastics, including the process differences between clear, cosmetic and structural parts.
Visual inspection, dimensional control and trial assembly — quality is confirmed before shipment, not after a complaint.
