About Weisu

We are a company specializing in plastic injection and mold design and manufacturing.

Founded in 1997 (formerly known as Huatai Plastics Co., Ltd., established in 1984), Weisu Industrial Co., Ltd. is a professional company specializing in plastic injection molding and mold design and manufacturing, with over 40 years of industry experience. Founder Mr. Lin Wen-hua entered the manufacturing industry at the age of 16, working his way up from a low-level worker and witnessing the rise and fall of Taiwan's manufacturing sector. To adapt to market changes and achieve industrial upgrading, the company not only maintains its mold manufacturing, injection molding, and processing assembly businesses, but also actively expands its overseas customer base, promoting international development.
