🏭 What are Plastic Injection Moulds?

Plastic injection moulds are precision tooling systems used in injection moulding machines to manufacture plastic parts by injecting molten plastic material into a cavity. The material cools and solidifies, taking the shape of the cavity. This process is ideal for mass production of identical plastic components with high precision and repeatability.

At Laxmi Micro Industries, we have been manufacturing high-precision plastic injection moulds since 1987. Our injection moulds are engineered for automotive, packaging, pharmaceutical, consumer goods, and electronics industries. Using advanced CAD/CAM software and high-tech machineries, we deliver moulds with tolerances up to Β±0.01mm.

πŸ”§ Detailed Overview of Plastic Injection Mould Types

Two-Plate Moulds

The most common and cost-effective mould design with a single parting line. The runner system is located on the same side as the cavity. Ideal for most standard applications where runner separation is acceptable.

  • Simple design - lower cost
  • Easy maintenance
  • Suitable for automatic operation with robot or conveyor

Three-Plate Moulds

Features two parting lines - one for the runner and one for the part. The runner automatically separates from the part during mould opening, eliminating manual runner removal.

  • Automatic runner separation
  • Center gating capability
  • Higher initial cost but reduced labor

Stack Moulds

Multiple parting line design with two or more mould faces stacked together. Doubles or triples output without increasing machine tonnage significantly.

  • Up to 200% increased output
  • Reduced clamp force per cavity
  • Higher initial investment

Family Moulds

Single mould producing multiple different parts simultaneously. Ideal for assemblies requiring multiple components in matched quantities.

  • Reduced mould changeover time
  • Balanced cavity design required
  • Perfect for component assemblies

βœ… Key Features of Our Plastic Injection Moulds

  • Precision Machining - Tolerances up to Β±0.01mm for consistent part quality
  • Optimized Cooling Channels - Reduced cycle times and faster production
  • Wear-Resistant Materials - Hardened steel for extended mould life
  • Balanced Runner Systems - Uniform filling across all cavities
  • Easy Ejection - Optimized ejector pin placement for smooth part release
  • Venting Design - Proper venting for complete cavity filling without burns
  • Interchangeable Components - Easy replacement of wear parts
