Plastic Chair Injection Mold Manufacturing Process

1. Mold Design & Engineering

The foundation of a high-quality plastic chair mold lies in its design. Our engineering team uses advanced CAD/CAE software to create optimized designs, considering:

• Structural integrity – Ensuring the chair can support weight without deformation

• Ejection system – Smooth demolding to prevent damage

• Cooling channels – Efficient cooling for faster production cycles

• Material flow analysis – Preventing defects like air traps or uneven filling

2. High-Quality Mold Steel Selection

The durability of a plastic chair mold depends on the steel used. We offer:

• P20 Steel – Cost-effective for medium production runs

• H13 Steel – High heat resistance for long-lasting performance

• S136 Stainless Steel – Superior polishability for glossy finishes

All molds undergo heat treatment (quenching, tempering) to enhance hardness and wear resistance.

3. Precision CNC Machining & Polishing

Our factory is equipped with:

• CNC milling machines – For high-precision cavity and core machining

• EDM (Electrical Discharge Machining) – For intricate details

• Wire-cutting machines – For smooth, burr-free edges

After machining, molds are hand-polished to a mirror finish, ensuring smooth plastic chair surfaces.

4. Testing & Quality Control

Before mass production, we conduct trial runs to check:

• Mold performance – Smooth ejection, no defects

• Cycle time optimization – Faster production = lower costs

• Final product quality – Strength, finish, and dimensional accuracy

Frequently Asked Questions (FAQs)

Q: How long does it take to manufacture a plastic chair mold?

A: Typically 45-60 days, depending on complexity.

Q: What plastic materials are best for chairs?

A: PP (Polypropylene) is most common due to its flexibility and cost-effectiveness. Other options include ABS (durability) and PC (transparency/impact resistance).

Q: What is the lifespan of a plastic chair mold?

A: With proper maintenance, a high-quality mold can produce 500,000 to 1,000,000+ chairs.

Q: How can I reduce mold costs?

A: Optimize design, use standardized components, and choose the right steel grade for your production volume.
