1+1 Cavity Plastic Stool Mold: Two-Cavity Tooling for Efficient Furniture Production

ISM Mould proudly presents our 1+1 Cavity Plastic Stool Mold—a precision-engineered tooling solution designed specifically for the efficient production of plastic stools and seating products. The 1+1 cavity configuration enables simultaneous molding of two stool components or two complete stools per cycle, delivering enhanced productivity while maintaining exceptional quality and dimensional accuracy . Ideal for manufacturers of household furniture, outdoor seating, and industrial stacking stools.

Key Features

1. Optimized 1+1 Cavity Design

Our two-cavity configuration offers balanced efficiency:

  • Simultaneous production of two stool components or two complete stools per cycle

  • Enhanced productivity compared to single-cavity tooling

  • Ideal for medium to high-volume stool manufacturing

  • Balanced cavity layout ensuring consistent fill and cooling across both cavities

2. Robust Structural Engineering

Plastic stools require exceptional strength for reliable seating:

  • Reinforced rib structure integration for load-bearing capacity

  • Optimized wall thickness distribution preventing weak points and sink marks

  • Stress-resistant design ensuring durability under repeated use

  • Stacking feature compatibility for space-efficient storage and transport

3. Precision Mold Construction

Core and Cavity InsertsS136 / 2316 Stainless SteelHRC 48-52
Slider ComponentsPremium Tool SteelHRC 50-55
Mold BaseP20 / 4Cr13 SteelPre-hardened
Wear PlatesBronze / Graphite-embeddedLow friction
  • Mold life: Engineered for 500,000 to 1+ million injection cycles

4. Advanced Runner System

Our 1+1 stool molds feature optimized runner systems:

Runner TypeAdvantages
Hot RunnerNo runner waste, faster cycles, ideal for high-volume production
Cold RunnerLower initial investment, simpler maintenance, suitable for medium volumes

5. Optimized Cooling System

Efficient cooling is essential for cycle time optimization and part quality:

  • Strategically placed cooling channels ensuring uniform heat extraction

  • Enhanced cooling in thick sections such as seating surface and leg connections

  • Balanced temperature distribution minimizing warpage and shrinkage

6. Specialized Ejection System

Proper ejection ensures clean part release without damage:

  • Multi-point ejection for large surface area parts

  • Synchronized ejector pins ensuring balanced part release

  • Optional robotic part removal for automated production
