Integrated Plastic Molding Solutions
While our core focus is injection molding, we also handle vacuum forming, thermoset molding, and blow molding, and we support both small-lot and prototype production.
Our projects range from retail displays to aircraft interior parts, pneumatic equipment, and security or disaster-prevention components. We process challenging materials such as super engineering plastics, eco-friendly resins, and glass fiber–reinforced plastics.
From mold design to molding, finishing, and assembly, we provide integrated solutions tailored to each project.
Balancing Every Detail
Injection molding requires the careful adjustment of numerous factors—such as material temperature, mold temperature, injection speed, pressure, and clamping force—through repeated trial runs. Even the smallest variation can greatly affect the final result.
While many cases are considered difficult to mold due to narrow process windows, we go a step further. Under strict quality control, we continually refine molding conditions to bring out the best in each material and product shape. By balancing temperature, pressure, and resin flow with precision, we achieve stable, high-quality mass production even under challenging conditions.
