Mixing, Heating, Injection Molding: The Birth of Plastic Parts

Injection molding is the core process for producing components for ergonomic chairs, training chairs, plastic chairs, stackable chairs, and more. The quality of molded parts directly affects structural strength, assembly accuracy, and long-term reliability of the final chair.

MSDA's injection workshop is equipped with large-scale machines and self-developed molds, building a highly controllable manufacturing system. We deliver reliable molding solutions from three dimensions:

Precision Molding
Plastic raw materials are precisely weighed, blended, and heated to strict temperature specifications. The molten material is injected into large mold cavities, then cooled and demolded. Key parameters – temperature, pressure, and holding time – are monitored in real time to ensure consistent dimensional accuracy across every batch.

Self-Developed Molds
Our mold workshop handles everything from cutting and rough machining to finishing, assembly, and debugging. Our technical team independently designs and builds various injection molds. Combined with presses, these molds enable high‑precision, high‑volume production of complex parts such as backrests, bases, and writing tablets.

Flexible Customization
We support custom colors and sizes. From design sketches and 3D renderings to precise color matching, every step is under our control. We commit to delivering samples within 2 days for fast validation, meeting diverse project requirements for customized plastic parts.

We consistently uphold precision and stability throughout our injection processes. From pellets to finished components, every operation follows strict procedures, laying a solid quality foundation for our entire commercial seating portfolio.
