Backed by 40+ years of parent-company expertise and 20 years of Vietnam operations.
Experienced specialists supporting complex production programs.
A-SPARK Manufacturing builds on the legacy of its parent company, LEGE Corp, which brings more than 40 years of experience in Taiwan and 20 years of operations in Vietnam. That foundation shapes a practical, engineering-driven approach focused on precision, reliability, and responsive project support for global OEMs and industrial buyers. From its base in Bac Ninh Province and regional manufacturing connections including Dongguan, the company supports customers across Asia, North America, Mexico, and India with coordinated sourcing, quality assurance, assembly, and logistics. Its vision is to be a dependable long-term production partner that helps customers scale confidently through disciplined quality systems, transparent communication, and end-to-end manufacturing support.
Plastic molding processes commonly include injection molding, insert molding, overmolding, blow molding, compression molding, rotational molding, and thermoforming. For precision components, injection molding is widely used for repeatability and tight tolerances. Insert molding specifically combines plastic with metal or other embedded components in one molded part, which can reduce assembly steps, improve durability, and support more compact product designs.
