The Role of Horizontal Injection Moulding Machines in Eyewear & Accessories

A Complete Guide on Injection Moulding Machine

From lightweight spectacle frames to sleek optical accessories, today’s eyewear industry demands precision, uniformity, and speed. Horizontal injection moulding machines have become the backbone of modern eyewear production. At Pratishna Engineers, we provide servo-controlled horizontal moulding machines tailored to meet the exacting standards of eyewear design, material handling, and mass production.

What is a Horizontal Injection Moulding Machine for Eyewear?

A horizontal injection moulding machine injects molten polymer into a mould placed horizontally along the clamping axis. For eyewear applications, it enables:

  • 🕶️ Moulding of full spectacle frames, arms, or bridges
  • 🧰 Manufacturing of accessories like covers, cases, nose pads, clips
  • 🔍 Use of clear and colored optical-grade materials like nylon, TR90, cellulose acetate, polycarbonate

This setup is ideal for multi-cavity, repeatable output — essential for eyewear OEMs and private label brands.

Why Eyewear Manufacturers Prefer Horizontal Machines

In India’s eyewear hubs like Mumbai, Delhi NCR, Surat, and Bhiwadi, manufacturers face demand for:

  • 🧠 Sharp dimensional tolerance for frame hinges and lenses
  • 🎨 Clean surface finish with no runner marks or deformities
  • 🔁 Repeatable output for bulk orders
  • 🔬 Compatibility with clear resins like PC, PMMA, TR90

Horizontal injection moulding ensures tight part alignment, robot integration, and efficient demoulding of intricate eyewear parts.

Common Buyer Questions & 2025 Moulding Trends for Eyewear

Frequently Asked by Buyers:

  • “Which tonnage is ideal for spectacle frames?”
  • “Can I run transparent polycarbonate on this machine?”
  • “Will my mould’s fine features hold up under high pressure?”
  • “What’s the best way to handle multiple frame sizes?”

2025 Industry Trends:

  • 🌿 Use of eco-friendly TR90 and bio-acetate polymers
  • 🧠 Thin-walled frames with internal reinforcement ribs
  • 🤖 Automation for demoulding and trimming
  • 📦 OEMs demanding consistent color accuracy and material purity

➡️ In the next section, we’ll show how Pratishna’s horizontal machines meet these challenges in real-world eyewear manufacturing.

Horizontal vs Vertical – Which Is Better for Eyewear?

Feature Horizontal Machine Vertical Machine
Frame Part Precision Excellent Moderate
Optical Material Handling Best (clear resin flow) Limited
Multi-cavity Moulding Standard Limited
Insert/Overmoulding Possible Better
Floor Space Moderate Compact
Best Use Spectacle frames, arms, covers Insert parts or overmoulded trims

🧭 Tip: Use horizontal machines for core frame production, and vertical for small inserts or custom molded accessories.
