Service (Injection Molding)

Precision plastic molding driven by
expertise and innovation.

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.

Taisei’s Strengths

01

Reproducing Complex Geometries

Our engineers precisely control mold temperature, injection pressure, and cooling conditions to achieve optimal molding balance. Even with complex shapes or varying wall thicknesses, we ensure dimensional accuracy and surface quality for stable, high-precision results.

02

Crystal-Clear Molding

Using high-transparency grades of PMMA and PC, we produce thick transparent parts with minimal bubbles and whitening. By carefully controlling resin flow and pressure, we maintain clarity and visual quality even in complex shapes.

03

Precision Management

We meet the strict specifications required for aircraft interior parts, including galleys, flight decks, and lavatories for Boeing.
 Through a traceable, tightly controlled production system, we supply components to JAMCO Corporation, a global leader in aircraft interiors.
 The standards developed through these projects enable us to deliver high-precision products with stable, reliable quality.
