🔩 Leading Auto Unscrew Mould Manufacturers in India

Laxmi Micro Industries is one of India's most trusted auto unscrew mould manufacturers, with a legacy spanning over 35 years. Founded in 1987 by Mr. Shantilal Panchal, we have consistently delivered precision-engineered unscrewing moulds for caps, closures, and threaded components to clients across the nation.

Our state-of-the-art facility in Ahmedabad is equipped with 5-axis CNC machining centers, wire-cut EDM, spark erosion machines, and CMM inspection. We specialize in rack & pinion and hydraulic unscrewing mechanisms for tamper-evident caps, child-resistant closures, and multi-start threads.

As a leading auto unscrew mould manufacturer in India, we serve industries including beverage, pharmaceutical, personal care, food, automotive, and industrial packaging.

⚙️ Our Unscrewing Mechanisms

  • Rack & Pinion Unscrewing - Mechanical unscrewing using rack and gear system. Cost-effective and reliable for standard applications.
  • Hydraulic Unscrewing - Hydraulic motor-driven unscrewing for larger threaded components and high-torque requirements.
  • Hydraulic + Rack Combination - Hybrid system for complex moulds with multiple unscrewing stations.
  • Pneumatic Unscrewing - Air-powered unscrewing for lightweight and small components.
  • Collapsible Core Technology - For components with undercuts and complex thread geometries.

❓ FAQs - Auto Unscrew Mould Manufacturers in India

1. What is the difference between rack & pinion and hydraulic unscrewing?
Rack & pinion unscrewing is a mechanical system driven by the mould's opening force. It is cost-effective and reliable for standard applications. Hydraulic unscrewing uses a separate hydraulic motor, providing higher torque and independent control, ideal for larger threads and complex moulds.
2. What is the typical lead time for an auto unscrew mould?
Our standard lead time is 15-25 days from design approval, depending on cavity count and complexity.
3. Do you provide trial runs before dispatch?
Yes, every auto unscrew mould undergoes live trial runs on injection moulding machines with sample parts and trial reports.
4. Can you manufacture moulds for multi-start threads?
Absolutely. We have extensive experience in designing auto unscrew moulds for multi-start threads, including 2-start, 3-start, and 4-start configurations.
