The Role of Vertical Injection Moulding Machines in Footwear Manufacturing

A Complete Guide on Injection Moulding Machine

Footwear manufacturing today demands speed, flexibility, and precision — especially in the moulding of soles, insoles, and embedded inserts. At Pratishna Engineers, our vertical injection moulding machines offer footwear manufacturers a space-saving, insert-friendly, and energy-efficient solution for plastic and polymer shoe components.

What is a Vertical Injection Moulding Machine for Footwear?

A vertical injection moulding machine injects molten plastic vertically into a mould placed on a horizontal clamping table. For footwear applications, this design supports:

  • 🥿 Direct moulding of soles, midsoles, and insoles
  • 🧦 Insert moulding of steel shanks, TPU heel counters, and arch supports
  • 🔁 Compact rotary/slide table setup for multi-station production

It’s widely used for thermoplastic soles (EVA, TPU, PVC) and insert components embedded into shoe constructions.

Why Footwear Factories Choose Vertical Machines Over Horizontal

Footwear OEMs and tier-2 suppliers in regions like Agra, Kanpur, Mumbai, and Surat are increasingly adopting vertical machines for:

  • 📏 Better control over insert placement (e.g., steel, TPU, air-cushion units)
  • 🔄 Rotary table models that allow mould loading/unloading while the cycle runs
  • 🦶 Better cycle ergonomics for manual sole setting and demoulding
  • 🧩 Precision alignment of mould halves for thin TPU/EVA sections
  • 🏭 Space optimization for smaller footwear units

Vertical machines are also preferred when moulding onto pre-moulded or stitched uppers.

FAQs & 2025 Trends in Vertical Footwear Moulding

Common Buyer Questions:

  • “Can vertical machines mould multi-color soles or double layers?”
  • “What types of polymers can I use in sole moulding?”
  • “Is rotary table better than slide for productivity?”
  • “Can I mould directly onto fabric or pre-assembled uppers?”

2025 Trends in Footwear Moulding:

  • 🔁 Insert moulding of metal supports and shanks is rising
  • ♻️ Recyclable TPU and bio-based EVA demand growing
  • 📈 Compact, semi-automatic vertical machines now favored by SMEs
  • 🛠️ Custom footbed and orthopedic sole moulding growing in medical-grade footwear

➡️ In the next section, we’ll show how Pratishna’s vertical machines are optimized for industrial footwear moulding — from soles to full inserts.

Vertical vs Horizontal for Footwear Moulding

Feature Vertical Machine Horizontal Machine
Insert Moulding Excellent Moderate (requires fixture)
Floor Space Compact Larger
Sole Moulding Yes Possible but less ergonomic
Labour Positioning Ergonomic Manual alignment harder
Automation Ready Easy rotary/slide table Complex with loaders
Best For Footwear, small parts, inserts Mass production of flat parts

🧭 Tip: Choose vertical for precision footwear parts with inserts or multi-layer soles.

Buyer Tip – How to Select a Vertical Machine for Footwear

When selecting a vertical injection moulding machine for shoes, consider:

  1. Table type: Use rotary for continuous cycling; slide for lower volume
  2. Clamping force: Based on sole thickness and mould size
  3. Injection unit size: Ensure it matches your largest sole shot weight
  4. Insert alignment needs: Go for servo + position sensor support
  5. Footprint vs throughput: Match to your factory space and daily output
