Injection Molding Machines

The critical alignments of any injection molding machine are platen-to-platen parallelism and guideway squareness to the fixed platen. Poor alignment results in premature wear on the mold, part flashing, and stress on tie bars. With long lead times and mold costs of $75,000 or more, proper alignment can significantly reduce costly machine downtime and repairs.

L-730 Precision Leveling Laser Alignment System

The product of more than 50 years of alignment experience, Hamar Laser offers 2 solutions for aligning an injection molding machine:

  1. L-732 Dual Scan® Laser Alignment System – for large injection machines, the L-732 utilizes 2 auto-rotating lasers planes to offer guideway flatness/leveling, straightness and twist measurements, plus platen parallelism and squareness of the fixed platen to the guideways.
  2. L-730 Leveling Laser – a single, auto-rotating laser plane system used on smaller injection molding machines to measure platen parallelism.  Can also be used for leveling.

These systems offer many benefits, such as:

  • Measure platen flatness, guideway straightness, twist & squareness to fixed platen, and platen parallelism data quickly and easily with high accuracy.
  • Measuring leveling & flatness of machine guideways and squareness to the platens.
  • Using laser planes reduces the number of setups and combined with real-time measurement data, alignment times are cut by up to 70%.
  • Very simple to use and easy to set up with minimal training needed.
  • With a range of 100 ft. (30.5 m) in radius, even the largest injection molding machines can be easily measured.
  • Laser planes have a flatness accuracy of 2.0 arc seconds (.00012 in/ft or 0.01 mm/m).
  • Uses A-1519-2.4ZB Wireless Target with .00002 resolution (0.0005 mm).
  • Wireless data transmission to R-1358-2.4XBE PDA Android Data Display that can display data values for up to 5 targets simultaneously.
