High-Volume Seating Programs
Armless chairs are commonly produced for events, cafeterias, and outdoor dining. This mold focuses on stacking stability, consistent finish, and repeatable cycle times for volume production.
Typical Use
Event seating, schools, rental fleets, and outdoor dining where chairs are stacked and transported frequently.
Leg Junction Reinforcement
Chair failures typically start at leg junctions and seat edges. We reinforce these areas while keeping wall thickness balanced for clean surfaces.
Key Engineering Points
- Leg junction ribs to distribute load
- Stacking stops for aligned stacking
- Cooling layout to reduce sink and warpage
- Surface texture options for scratch resistance

Frequently Asked Questions
Common questions about our Plastic Armless Chair Mold
How many chairs can be stacked?
Stacking count depends on chair profile and material. We can tune the stacking geometry for your target count.
Is UV resistance available for outdoor use?
Yes. We recommend UV-stabilized PP for outdoor applications.
Can we choose different surface textures?
Yes. We can provide matte, textured, or polished surface finishes.
Which materials are recommended?
PP is standard for cost and durability; ABS is available for higher stiffness if needed.
Can you add branding on the chair?
Yes. We can include embossed or debossed logos on the backrest or seat area.
