Micro-Molding Injection Molding Machine can reduce clamp tonnage.

Press Release Summary:

Designed for repeatability and accurate plasticization, GL30-LP provides advanced injection for micro features with extremely tight tolerances. Machine can reduce its rated 30 ton clamp tonnage to 5% (1.5 tons) without loss of accuracy, and injection response time is 2–3 msec. For consistent measurement and injection of melt stream, V-Line 2-stage plunger system separates plasticization and injection processes. Other features include hybrid clamping mechanism and 4.5 cc barrel.

Plustech Unveils New Micro-Molding Injection Molding Machine

The GL30-LP is able to reduce clamp tonnage to an amazing 5 percent and features the highest injection response time in its class, at an impressive 2-3 ms.

Schaumburg, IL – Plustech, Inc., the North American Branch of Sodick’s IMM Division, unveiled a new model of injection molding machine during the recent MD&M show in Minneapolis, MN. The event included North America’s formal introduction of the GL30-LP, a micro-molding injection molding machine.

The GL30-LP is the latest addition to Plustech’s line-up of horizontal injection molding machines.  This high-performance model offers excellent repeatability and accurate plasticization. The machine provides advanced injection for micro features with extremely tight tolerances.  It includes Sodick’s V-Line two-stage plunger system, which separates the plasticization and injection processes for consistent measurement and injection of the melt stream.  The 30 ton machine incorporates a true hybrid clamping mechanism utilizing an upgraded servo motor controlled hydraulic pumping system.

With unparalleled platen alignment and a high rigidity clamp ensures that the clamping force is applied uniformly.  This new machine is able to reduce the clamp tonnage to an amazing 5 percent, dialing it down to 1.5 tons without losing any accuracy. The GL30-LP (4.5cc barrel) has the highest injection response time in its class at an impressive 2-3 ms, max injection velocity of 1,300mm/sec (51.1”/sec) and max injection pressure of 288MPa (41,730 psi). 

The GL30-LP featured a demo provided by MTD Micro Molding, out of Charlton, MA. The demo piece was a RTP’s Polysulfone RADEL® material, four-cavity micro (thin wall) bushing with Star Automation robot. “The bushing actually had a relatively basic tool construction compared to the majority of tools we build today,” stated Lindsay Mann, Director of Marketing for MTD Micro Molding. MTD Micro Molding is a Plustech customer and owns Sodick equipment.  “We have found the Sodick equipment very helpful in meeting our varied requirements. The machines do not require many modifications to successfully process a multitude of different materials.  We also are impressed with the machines repeatability,” stated Dennis Tully, President of MTD Micro Molding.

MTD Micro Molding has impressive in-house capabilities including a Sarix EDM machine that has a micro EDM capability and uses cutting tools with a diameter of a red blood cell; this allows the company to make much more complex part designs with a mirror-smooth surface finish, perfectly detailed corners and sharp edges a reality. MTD Micro Molding is a vertically integrated contract manufacturer that does 100 percent micro-medical work. The company does business with more than half of the top 25 medical device companies in the world and produces millions of micro components every year.
